Pin Name Description This pin outputs signals from the charge pump of the PLL frequency synthesizer. If the frequency divided from the local oscillator (VCO) frequency is higher (lower) than the reference frequency, high (low) level is output from this pin, respectively. When the two frequencies match, this pin is placed in the high-impedance state. This pin outputs pulse swallow control signal. This signal switches division ratio for the dedicated prescaler PB595. This pin is the input of the local oscillator. The output signal coming from the local oscillator (VCO) in the tuner and divided by the dedicated prescaler PB595 should be input to this pin, where the PB595 is a two-module prescaler capable of frequency division up to 1 GHz. This pin is the input of the H sync signal counter. This active-high pin outputs blanking signals to delete video signals. This active-high pin outputs character data that correspond the R signal (one of the RGB signals of IDC). This active-high pin outputs character data that correspond the G signal (one of the RGB signals of IDC). This active-high pin outputs character data that correspond the B signal (one of the RGB signals of IDC). This pin outputs character data that correspond the I signal of IDC. The H sync signals for IDC should be input to this pin in an active-low manner. The V sync signals for IDC should be input to this pin in an active-low manner. These are the input and output pins of the LC oscillation circuit for IDC. Adjust the oscillation frequency to 10 MHz. These are the analog input pins of the 6-bit resolution A/D converter.

Pin Name Description This pin selects a device to be activated, or resets this device. (1) Use as input of device selection signal When CE=high, PLL synthesizer and IDC operate. When CE=low, their operation are disabled (stops). (2) Use as reset input When CE changes from low to high, this device is reset in synchronization with the carry FF operation for the internal basic interval timer 0. This pin inputs the clock stop release signal. XIN XOUT An 8-MHz crystal resonator for main clock generation should be connected to these pins. These pins supply positive power voltage for this device. The power supply voltage of 5 V 10 % should be applied to these pins when all functions operate. When IDC is disabled, the voltage range from 4.0 to 5.5 V is allowed. When clock is stopped, the applied voltage to these pins may be lowered down to 2.5 V. Because this device internally has the power-on reset circuit, the voltages applied to these pins are changed from 0 to 4.0 V, system reset sequence is started and the program is implemented from address 0H. To assure normal operations of the power-on reset circuit, the rise time from 0 to 4.0 V should be shorter than 500 ms. These pins supply the ground level for this device. This pin should be left unconnected. -- -- -- -- I/O Output Type When Reset Shared by

Notes 1. Input ports go to input mode when the power supply rises, when the clock stops, and on CE reset. 2. Be careful of the fact that when an external pull-up (connection to VDD through a resistor) or pull-down (connection GND through a resistor) is made, if the pull-up or pull-down is done through a resistor with a high value, because the pin comes near to being in high impedance, the consumed (through) current increases. This also depends on the application circuit, but a typical value for a pull-up or pull-down resistor is a few tens of k.

1.5 Notes on Using the CE and INTNC Pins (Only in Normal Operation Mode) In addition to the functions shown in 1.1 Normal Operation Mode, the CE pin also has the function of setting a test mode (for IC testing) in which the internal operations of the PD17P068 are tested. Also, the INTNC pin has the function of the VPP pin for program memory write/verify. When a voltage higher than VDD is applied to either of these pins, the test or program memory write/verify mode is set. This means that, even during normal operation, the PD17P068 may be set in the test mode if noise exceeding VDD is applied. For example, if the wiring length of the CE or INTNC pin is too long, noise superimposed on the wiring line of the pin may cause the above problem. Therefore, keep the wiring length of these pins as short as possible to suppress the noise; otherwise, take noise preventive measures as shown below by using external components. * Connect diode with low VF between VDD and CE/INTNC pin

2. WRITE, READ, AND VERIFY OF ONE-TIME PROM (PROGRAM MEMORY)
The program memory contained in the PD17P068 is the 12160 x 16-bit one-time PROM that can electrically be written one time only. This PROM is accessed in 16 bits per word in normal operation mode, and in 8 bits per word in write, read, verify modes. The 16 bits of a word in normal mode are divided into higher 8 bits and lower 8 bits which are assigned to even and odd addresses, respectively. When the PROM is written, read, or verified, set this device into the PROM mode. In this mode, these pins are used as shown in the table below. Notice that no address input pins are provided. Addresses are automatically updated by the clock signal supplied from the CLK pin. Table 2-1. Pins Used in Program Memory Write, Read, and Verify Modes
Pin VPP CLK MD0-MD3 D0-D7 VDD0, VDD1 Function Programming voltage (+12.5 V) application Address update clock input Operation mode selection 8-bit data input/output Power supply voltage (+5 V) application

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it.
2 HANDLING OF UNUSED INPUT PINS FOR CMOS
Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices.
3 STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.

NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices in "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact NEC Sales Representative in advance. Anti-radioactive design is not implemented in this product.
