F2MC-16LX MB90820 Series MB90822/823/F822A/F823A/V820
DESCRIPTION
The MB90820 series is a line of general-purpose, Fujitsu 16-bit microcontrollers designed for process control applications which require high-speed real-time processing, such as consumer products. While inheriting the AT architecture of the F2MC* family, the instruction set for the F2MC-16LX CPU core of the MB90820 series incorporates additional instructions for high-level languages, supports extended addressing modes, and contains enhanced multiplication and division instructions as well as a substantial collection of improved bit manipulation instructions. In addition, the MB90820 series has an on-chip 32-bit accumulator which enables processing of long-word data. The peripheral resources integrated in the MB90820 series include : an 8/10-bit A/D converter, 8-bit D/A converters, UARTs (SCI) 0, 1, multi-functional timer (16-bit free-running timer, input capture units (ICUs) 0 to 3, output compare units (OCUs) 0 to 5, 16-bit PPG timer 0, waveform generator), 16-bit PPG timer 1, 2, PWC 0, 1, 16-bit reload timer 0, 1 and DTP/external interrupt. *: F2MC stands for FUJITSU Flexible Microcontroller, a registered trademark of FUJITSU LIMITED.

DIFFERENCES AMONG PRODUCTS
Memory Size In evaluation with an evaluation product, note the difference between the evaluation product and the product actually used. The following items must be taken into consideration. * The MB90V820 does not have an internal ROM, however, operations equivalent to chips with an internal ROM can be evaluated by using a dedicated development tool, enabling selection of ROM size by settings of the development tool. * In the MB90V820, images from FF8000H to FFFFFFH are mapped to bank 00, and FE0000H to FF7FFFH are mapped to bank FE and bank FF only. (This setting can be changed by configuring the development tool.) * In the MB90822/F822A, images from FF8000H to FFFFFFH are mapped to bank 00, and FF0000H to FF7FFFH are mapped to bank FF only. In the MB90823/F823A, images from FF8000H to FFFFFFH are mapped to bank 00, and FE0000H to FF7FFFH are mapped to bank FE and bank FF only.

HANDLING DEVICES
Special care is required for the following when handling the device : * Preventing latch-up * Stabilization of supply voltage * Treatment of unused pins * Using external clock * Power supply pins (VCC /VSS ) * Pull-up/pull-down resistors * Crystal Oscillator Circuit * Turning-on Sequence of Power Supply to A/D Converter and D/A Converter, and Analog Inputs * Connection of Unused Pins of A/D Converter and D/A Converter if A/D Converter and D/A Converter are unused * Notes on energization * Notes on During Operation of PLL Clock Mode
1. Preventing latch-up
CMOS IC chips may suffer latch-up under the following conditions : * A voltage higher than VCC or lower than VSS is applied to an input or output pin. * A voltage higher than the rated voltage is applied between VCC and VSS. * The AVCC power supply is applied before the VCC voltage. Latch-up may increase the power supply current drastically, causing thermal damage to the device. In using the devices, take sufficient care to avoid exceeding maximum ratings. For the same reason, also be careful not to let the analog power-supply voltage (AVCC, AVR) exceed the digital power-supply voltage.
2. Stabilization of supply voltage
A sudden change in the supply voltage may cause the device to malfunction even within the specified VCC supply voltage operation range. Therefore, the VCC supply voltage should be stabilized. For reference, the supply voltage should be controlled so that VCC ripple variations (peak-to-peak values) at commercial frequencies (50 Hz to 60 Hz) fall below 10% of the standard VCC supply voltage and the coefficient of fluctuation does not exceed 0.1 V/ms at instantaneous power switching.
3. Treatment of unused pins
Leaving unused input pins open may result in misbehavior or latch up and possible permanent damage of the device. Therefore they must be pulled up or pulled down through resistors. In this case those resistors should be more than 2 k. Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above described connection.
4. Using external clock
To use external clock, drive the X0 pin and leave X1 pin open. MB90820 series

5. Power supply pins (VCC/VSS)
* If there are multiple VCC and VSS pins, from the point of view of device design, pins to be of the same potential are connected the inside of the device to prevent such malfunctioning as latch up. To reduce unnecessary radiation, prevent malfunctioning of the strobe signal due to the rise of ground level, and observe the standard for total output current, be sure to connect the VCC and VSS pins to the power supply and ground externally. * Connect VCC and VSS to the device from the current supply source at a low impedance. * As a measure against power supply noise, connect a capacitor of about 0.1 F as a bypass capacitor between VCC and VSS in the vicinity of VCC and VSS pins of the device.

6. Pull-up/pull-down resistors
The MB90820 series does not support internal pull-up/pull-down resistors option (Port 0 to Port 3 : built-in pullup resistors) . Use external components where needed.
7. Crystal oscillator circuit
Noises around X0 or X1 pins may be possible causes of abnormal operations. Make sure to provide bypass capacitors via shortest distance from X0, X1 pins, crystal oscillator (or ceramic oscillator) and ground lines, and make sure, to the utmost effort, that lines of oscillation circuit do not cross the lines of other circuits while you design a printed circuit board. It is highly recommended to provide a printed circuit board art work surrounding X0 and X1 pins with a ground area for stabilizing the operation.
8. Turning-on sequence of power supply to A/D converter and D/A converter, and analog inputs
Make sure to turn on the A/D converter power supply, D/A converter power supply (AVCC, AVRH, AVR) and analog inputs (AN0 to AN15) after turning-on the digital power supply (VCC). Turn-off the digital power after turning off the A/D converter power supply, D/A converter power supply, and analog inputs. In this case, make sure that the voltage not exceed AVR or AVCC (turning on/off the analog and digital power supplies simultaneously is acceptable).
9. Connection of unused pins of A/D converter and D/A converter if A/D converter and D/A converter are unused
Connect unused pins of A/D converter and D/A converter to AVCC = VCC, AVSS = AVRH = AVRL = VSS.
10. Notes on energization
To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at 50 s or more (0.2 V to 2.7 V) . 16
MB90820 Series
11. Notes on During Operation of PLL Clock Mode
If the PLL clock mode is selected, the microcontroller attempts to be working with the self-oscillating circuit even when there is no external oscillator or external clock input is stopped. Performance of this operation, however, cannot be guaranteed.

Note: The ROM data of bank FF is reflected to the upper address of bank 00, realizing effective use of the C compiler small model. The lower 16-bit is assigned to the same address, enabling reference of the table on the ROM without stating "far". For example, if an attempt has been made to access 00C000H, the contents of the ROM at FFC000H are accessed actually. Since the ROM area of the FF bank exceeds 32K bytes, the whole area cannot be reflected in the image for the 00 bank. The ROM data at FF8000H to FFFFFFH looks, therefore, as if it were the image for 008000H to 00FFFFH. Thus, it is recommended that the ROM data table be stored in the area of FF8000H to FFFFFFH.

The MB90820 series has the following CPU operating mode configured by selection of an operating clock and clock operation control. * Clock mode PLL clock mode : A PLL clock that is a multiple of the oscillation clock (HCLK) frequency is used to operate the CPU and peripheral functions. Main clock mode : The main clock, with a frequency one-half that of the oscillation clock (HCLK), is used to operate the CPU and peripheral functions. In main clock mode, the PLL divide circuit is inactive. * CPU intermittent operation mode CPU intermittent operation mode causes the CPU to operate intermittently, while high-speed clock pulses are supplied to peripheral functions, reducing power consumption. In CPU intermittent operation mode, clock pulses are supplied intermittently to the CPU when it is accessing a register, internal memory, a peripheral function, or an external unit. * Standby mode In standby mode, the low power consumption control circuit reduces power consumption by stopping; * The supply of the clock to CPU (sleep mode) * CPU and peripheral functions (timebase timer mode) * The oscillation clock itself (stop mode) * PLL sleep mode PLL sleep mode is activated to stop the CPU operating clock when the microcontroller enters PLL clock mode; other components continue to operate on the PLL clock. * Main sleep mode Main sleep mode is activated to stop the CPU operating clock when the microcontroller enters main clock mode; other components continue to operate on the main clock. * PLL timebase timer mode PLL timebase timer mode causes microcontroller operation, with the exception of the oscillation clock, PLL clock and timebase timer, to stop. All functions other than the timebase timer are deactivated. * Main timebase timer mode Main timebase timer mode causes microcontroller operation, with the exception of the oscillation clock, main clock and the timebase timer, to stop. All functions other than the timebase timer are deactivated. * Stop mode Stop mode causes the source oscillation to stop. All functions are deactivated.

5. 16-bit reload timer ( x 2)
The 16-bit reload timer provides two operating mode, internal clock mode and event count mode. In each operating mode, the 16-bit down counter can be reloaded (reload mode) or stopped by underflow (one-shot mode). Output pins TO1 and TO0 are able to output different waveform according to the counter operating mode. TO1 and TO0 toggles when counter underflows if counter is operated as reload mode. TO1 and TO0 output specified level (H or L) during counting if the counter is in one-shot mode. Features of the 16-bit reload timer : * Interrupt when timer underflows * Supports for EI2OS * Internal clock operating mode : Three internal count clocks can be selected. Counter can be activated by software or external trigger (signal at TIN1 and TIN0 pins). Counter can be reloaded or stopped when underflow after activated. * Event count operating mode : Counter counts down one by one with specified edge at TIN1 and TIN0 pins. Counter can be reloaded or stopped when underflow. (1) Register configuration

7. Multi-functional Timer
The 16-bit multi-functional timer module consists of one 16-bit free-running timer, four input capture circuits, six output comparators and one channel of 16-bit PPG timer. This module allows six independent waveforms generated by PPG timer or waveform generator to be outputted. With the 16-bit free-running timer and the input capture circuit, input pulse width and external clock period measurement can be done. (1) 16-bit free-running timer (1 channel) * The 16-bit free-running timer consists of a 16-bit up counter, 16-bit up-down counter, timer control status register, 16-bit compare clear register (with buffer register) and a prescaler. * 8 types of counter operation clock (, /2, /4, /8, /16, /32, /64, /128) can be selected. ( is the machine clock.) * Two types of interrupt causes : - Compare clear interrupt is generated when there is a comparing match with compare clear register and 16bit free-running timer. - Zero detection interrupt is generated while 16-bit free-running timer is detected as zero in count value. * EI2OS supported. * Compare-clear register buffer provided : The selectable buffer enables the 16-bit free-running timer update its compare-clear register automatically without stop the timer operation. User can read the next compare-clear value to the compare-clear register when the timer is running. The compare-clear register will be updated when the timer value is "0000H" * Reset, software clear, compare match with compare clear register in up-count mode will reset the counter value to "0000H". * Supply clock to output compare module : The prescaler output is acted as the count clock of the output compare. (2) Output compare module ( 6 channels) * The output compare module consists of six 16-bit output compare registers (with selectable buffer register), compare output latch and compare control registers. An interrupt is generated and output level is inverted when the value of 16-bit free-running timer and output compare register are matched. * 6 output compare registers can be operated independently. * Output pins and interrupt flag are corresponding to each output compare register. * 2 output compare registers can be paired to control the output pins. * Inverts output pins by using 2 output compare registers together. * Setting the initial value for each output pin is possible. * Interrupt is generated when there is a comparing match with output compare register and 16-bit free-running timer. * EI2OS supported. (3) Input capture module (4 channels) Input capture consists of 4 independent external input pins, the corresponding input capture data register and input capture control status register. By detecting any edge of the input signal from the external pin, the value of the 16-bit free-running timer can be stored in the capture register and an interrupt is generated simultaneously. * Operations synchronized with the 16-bit free-running timer's count clock. * 3 types of trigger edge (rising edge, falling edge and both edge) of the external input signal can be selected and there is indication bit to show the trigger edge is rising or falling. * 4 input captures can be operated independently. * Two independent interrupts are generated when detecting a valid edge from external input. * EI2OS supported.

(4) 16-bit PPG timer (1 channel) The 16-bit PPG timer 0 is used to provide a PPG signal for waveform generator. (See section "6. 16-bit PPG Timer (x 3) ".) (5) Waveform generator module The waveform generator consists of three 16-bit timer registers, three 16-bit timer control registers and a waveform control register. With waveform generator, it is possible to generate real time output, 16-bit PPG waveform output, non-overlap 3-phase waveform output for inverter control and DC chopper waveform output. * It is possible to generate a non-overlap waveform output based on dead-time of 16-bit timer. (Dead-time timer function) * It is possible to generate a non-overlap waveform output when realtime output is operated in 2-channel mode. (Dead-time timer function) * By detecting realtime output compare match, GATE signal of the PPG timer operation will be generated to start or stop PPG timer operation. (GATE function) * When a match is detected by real time output compare, the 16-bit timer is activated. The PPG timer can be started or stopped easily by generating a GATE signal for PPG operation until the 16-bit timer stops. (GATE function) * Force to stop output waveform using DTTI pin input. * Interrupt is generated when DTTI active or 16-bit timer underflow. * EI2OS is supported. (6) Register configuration * 16-bit free-running timer registers

8. PWC Timer ( x 2)
The PWC (pulse width count) timer is a 16-bit multi-functional up counter with reload timer functions and input signal pulse width count functions. The PWC timer consists of a 16-bit counter, an input pulse divider, a division ratio control register, a count input pin, a pulse output pin, and a 16-bit control register. The PWC timer has the following features: * Interruption is generated when timer overflow or end of PWC measurement. * EI2OS is supported. * Timer functions : - Generates an interrupt request at set time intervals. - Outputs pulse signals synchronized with the timer cycle. - Selects the counter clock from three internal clocks. * Pulse-width count functions: - Counts the time between external pulse input events. - Selects the counter clock from three internal clocks. - Count mode: * H pulse width (rising edge to falling edge) / L pulse width (falling edge to rising edge) * Rising-edge cycle (rising edge to falling edge) / Falling-edge cycle (falling edge to rising edge) * Count between edges (rising or falling edge to falling or rising edge) Capable of counting cycles by dividing input pulses by 22, 24, 26, 28 using an 8-bit input divider. Generates an interrupt request upon the completion of count operation. Selects single or consecutive count operation. (1) Register configuration

12. A/D Converter
The A/D converter converts the analog voltage input (input voltage) to an analog input pin to a digital value. It has the following features : * The minimum conversion time is 3 s (for a machine clock of 24 MHz; including sampling time). * The converter uses the RC-type successive approximation conversion method with a sample and hold circuit. * A resolution of 10 bits or 8 bits can be set. * Up to 16 channels for analog input pins can be selected by a program. * Various conversion mode : - Single conversion mode : Selectively convert one channel. - Scan conversion mode : Continuously convert multiple channels. Maximum of 16 selectable channels. - Continuous conversion mode : Repeatedly convert specified channels. - Stop conversion mode : Convert one channel then halt until the next activation (enables synchronization of the conversion start timing). * At the end of A/D conversion, an interrupt request can be generated and EIOS can be activated. * In the interrupt-enabled state, the conversion data protection function prevents any part of the data from being lost through continuous conversion. * The conversion can be activated by software, 16-bit reload timer 1 (rising edge) and 16-bit free-running timer zero detection edge.

13. D/A Converter
The D/A converter is used to generate an analog output from an 8-bit digital input. By setting the enable bit in the D/A control register (DACR) to 1, it will enable the corresponding D/A output channel. Hence, setting this bit to 0 will disable that channel. If D/A output is disabled, the analog switch inserted to the output of each D/A converter channel in series is turned off. In the D/A converter, the bit is cleared to 0 and the direct-current path is shut off. The above is also true in the stop mode. The output voltage of the D/A converter ranges from 0 V to 255/256 x AVCC. To change the output voltage range, adjust the AVCC voltage externally. The D/A converter output does not have the internal buffer amplifier. The analog switch (= 100 ) is inserted to the output in series. To apply load to the output externally, estimate a sufficient stabilization time. Table below lists the theoretical values of output voltage of the D/A converter. Value written to DA07 to DA00 and DA17 to DA10 00H 01H 02H : FDH FEH FFH Theoretical value of output voltage 0/256 x AVCC (= 0 V) 1/256 x AVCC 2/256 x AVCC : 253/256 x AVCC 254/256 x AVCC 255/256 x AVCC

14. ROM Correction Function
When the corresponding address matches the value set in the address detection register, the instruction code to be loaded into the CPU is forced to be replaced with the INT9 instruction code (01H). When executing a set instruction, the CPU executes the INT9 instruction. The address detection function is implemented by processing using the INT9 instruction routine. The device contains two address detection registers, each provided with a compare enable bit. When the value set in the address detection register matches an address and the interrupt enable bit is "1", the instruction code to be loaded into the CPU is forced to be replaced with the INT9 instruction code.

16. 512K/1024K bits Flash Memory
The 512K bits flash memory is allocated in the FFH banks on the CPU memory map. The 1024K bits flash memory is allocated in the FEH and FFH banks on the CPU memory map. Like Mask ROM, flash memory is read-accessible and program-accessible to the CPU using the flash memory interface circuit. The flash memory can be programmed/erased by the instruction from the CPU via the flash memory interface circuit. The flash memory can therefore be reprogrammed (updated) while still on the circuit board under integrated CPU control, allowing program code and data to be improved efficiently. Note that sector operations such as "enable sector protect" cannot be used.

*1 : This parameter is based on VSS = AVSS = 0.0 V. *2 : AVCC must never exceed VCC when the power is turned on. *3 : VI and VO must never exceed VCC + 0.3 V. However if the maximum current to/from an input is limited by some means with external components, the ICLAMP rating supersedes the VI rating. *4 : The maximum output current is a peak value for a corresponding pin. *5 : * * * * Applicable to pins: P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50, P51, P80 to P87. Use within recommended operating conditions. Use at DC voltage (current). The +B signal is an input signal exceeding VCC voltage. The +B signal should always be applied a limiting resistance placed between the +B signal and the microcontroller. * The value of the limiting resistance should be set so that when the +B signal is applied the input current to the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods. * Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input potential may pass through the protective diode and increase the potential at the Vcc pin, and this may affect other devices.
78
MB90820 Series
* Note that if a +B signal is input when the microcontroller power supply is off (not fixed at 0 V), the power supply is provided from the pins, so that incomplete operation may result. * Note that if the +B input is applied during power-on, the power supply is provided from the pins and the resulting supply voltage may not be sufficient to operate the power-on reset. * Care must be taken not to leave the +B input pin open. * Note that analog system input/output pins (LCD drive pins and comparator input pins, etc.) other than the A/D input pins cannot accept +B input. * Sample recommended circuits:

7. Notes on Using A/D Converter
* About the external impedance of the analog input and its sampling time * A/D converter with sample and hold circuit. If the external impedance is too high to keep sufficient sampling time, the analog voltage charged to the internal sample and hold capacitor is insufficient, adversely affecting A/D conversion precision. Therefore, to satisfy the A/D conversion precision standard, consider the relationship between the external impedance and minimum sampling time and either adjust the resistor value and operating frequency or decrease the external impedance so that the sampling time is longer than the minimum value. And if the sampling time cannot be sufficient, connect a capacitor of about 0.1 mF to the analog input pin. * Analog input circuit model
