DESCRIPTION
The CAT15008/16 (see table below) are memory and supervisory solutions for microcontroller based systems. A CMOS serial EEPROM memory and a system power supervisor with brown-out protection are integrated together. Memory interface is via SPI bus serial interface. The CAT15008/16 provides a precision VCC sense circuit with two reset output options: CMOS active low output or CMOS active high. The RESET output is active whenever VCC is below the reset threshold or falls below the reset threshold voltage. The power supply monitor and reset circuit protect system controllers during power up/down and against brownout conditions. Seven reset threshold voltages support 5V, 3.3V, 3V and 2.5V systems. If power supply voltages are out of tolerance reset signals become active, preventing the system microcontroller, ASIC or peripherals from operating. Reset signals become inactive typically 240ms after the supply voltage exceeds the reset threshold level.

CAT15008, CAT15016 PIN DESCRIPTION
RESET/RESET: Reset output is available in two versions: CMOS Active Low (CAT150xx9) and CMOS Active High (CAT150xx1). Both versions are push-pull outputs for high efficiency. SI: The serial data input pin accepts op-codes, addresses and data. In SPI modes (0,0) and (1,1) input data is latched on the rising edge of the SCK clock input. SO: The serial data output pin is used to transfer data out of the device. In SPI modes (0,0) and (1,1) data is shifted out on the falling edge of the SCK clock. SCK: The serial clock input pin accepts the clock provided by the host and used for synchronizing communication between host and CAT15008/16. CS: The chip select input pin is used to enable/disable the CAT15008/16. When CS is high, the SO output is tri-stated (high impedance) and the device is in Standby Mode (unless an internal write operation is in progress). Every communication session between host and CAT15008/16 must be preceded by a high to low transition and concluded with a low to high transition of the CS input. : The write protect input pin will allow all write WP operations to the device when held high. When WP pin is tied low and the WPEN bit in the Status Register (refer to Status Register description, later in this Data Sheet) is set to "1", writing to the Status Register is disabled.
DEVICE OPERATION
The CAT15008/16 products combine the accurate voltage monitoring capabilities of a standalone voltage supervisor with the high quality and reliability of standard EEPROMs from Catalyst Semiconductor.
RESET CONTROLLER DESCRIPTION
The reset signal is asserted LOW for the CAT150xx9 and HIGH for the CAT150xx1 when the power supply voltage falls below the threshold trip voltage and remains asserted for at least 140ms (tPURST) after the power supply voltage has risen above the threshold. Reset output timing is shown in Figure 1. The CAT15008/16 devices protect Ps against brown-out failure. Short duration VCC transients of 4sec or less and 100mV amplitude typically do not generate a Reset pulse.

Figure 2 shows the maximum pulse duration of negative-going VCC transients that do not cause a reset condition. As the amplitude of the transient goes further below the threshold (increasing VTH - VCC), the maximum pulse duration decreases. In this test, the VCC starts from an initial voltage of 0.5V above the threshold and drops below it by the amplitude of the overdrive voltage (VTH - VCC).

EMBEDDED EEPROM DESCRIPTION
The CAT15008/16 devices support the Serial Peripheral Interface (SPI) bus protocol, modes (0,0) and (1,1). The device contains an 8-bit instruction register. The instruction set and associated op-codes are listed in Table 1. Reading data stored in the CAT15008/16 is accom- plished by simply providing the READ command and an address. Writing to the CAT15008/16, in addition to a WRITE command, address and data, also requires enabling the device for writing by first setting certain bits in a Status Register, as will be explained later. After a high to low transition on the CS input pin, the CAT15008/16 will accept any one of the six instruction op-codes listed in Table 1 and will ignore all other possible 8-bit combinations. The communication protocol follows the timing from Figure 3.

CAT15008, CAT15016 STATUS REGISTER
The Status Register, as shown in Table 2, contains a number of status and control bits. The (Ready) bit indicates whether the device is RDY busy with a write operation. This bit is automatically set to 1 during an internal write cycle, and reset to 0 when the device is ready to accept commands. For the host, this bit is read only. The WEL (Write Enable Latch) bit is set/reset by the WREN/WRDI commands. When set to 1, the device is in a Write Enable state and when set to 0, the device is in a Write Disable state. The BP0 and BP1 (Block Protect) bits determine which blocks are currently write protected. They are set by the user with the WRSR command and are non-volatile. The Table 2. Status Register 7 WPEN 6 0 5 0 4 0 3 BP1 2 BP0 1 WEL 0 RDY user is allowed to protect a quarter, one half or the entire memory, by setting these bits according to Table 3. The protected blocks then become read-only. The WPEN (Write Protect Enable) bit acts as an enable for the pin. Hardware write protection is enabled WP when the pin is low and the WPEN bit is 1. This WP condition prevents writing to the status register and to the block protected sections of memory. While hardware write protection is active, only the non-block protected memory can be written. Hardware write protection is disabled when the pin is high or the WP WPEN bit is 0. The WPEN bit, pin and WEL bit WP combine to either permit or inhibit Write operations, as detailed in Table 4.

CAT15008, CAT15016 WRITE OPERATIONS
The CAT15008/16 device powers up into a write disable state. The device contains a Write Enable Latch (WEL) which must be set before attempting to write to the memory array or to the status register. In addition, the address of the memory location(s) to be written must be outside the protected area, as defined by BP0 and BP1 bits from the status register. take the CS input high after the WREN instruction, as otherwise the Write Enable Latch will not be properly set. WREN timing is illustrated in Figure 4. The WREN instruction must be sent prior any WRITE or WRSR instruction. The internal write enable latch is reset by sending the WRDI instruction as shown in Figure 5. Disabling write operations by resetting the WEL bit, will protect the device against inadvertent writes.
Write Enable and Write Disable
The internal Write Enable Latch and the corresponding Status Register WEL bit are set by sending the WREN instruction to the CAT15008/16. Care must be taken to Figure 4. WREN Timing

Byte Write Once the WEL bit is set, the user may execute a write sequence, by sending a WRITE instruction, a 16-bit address and data as shown in Figure 6. Only 10 significant address bits are used by the CAT15008 and 11 by the CAT15016. The rest are don't care bits, as shown in Table 5. Internal programming will start after the low to high CS transition. During an internal write cycle, all commands, except for RDSR (Read Status Register) will be ignored. The bit will RDY indicate if the internal write cycle is in progress (RDY high), or the the device is ready to accept commands (RDY low). Table 5. Byte Address Device CAT15008 CAT15016 Address Significant Bits A9 - A0 A10 - A0 Address Don't Care Bits A15 - A10 A15 - A11 # Address Clock Pulse 16 16 Page Write After sending the first data byte to the CAT15008/16, the host may continue sending data, up to a total of 32 bytes, according to timing shown in Figure 7. After each data byte, the lower order address bits are automatically incremented, while the higher order address bits (page address) remain unchanged. If during this process the end of page is exceeded, then loading will "roll over" to the first byte in the page, thus possibly overwriting previoualy loaded data. Following completion of the write cycle, the CAT15008/16 is automatically returned to the write disable state.

CAT15008, CAT15016 READ OPERATIONS
Read from Memory Array To read from memory, the host sends a READ instruction followed by a 16-bit address (see Table 5 for the number of significant address bits). After receiving the last address bit, the CAT15008/16 will respond by shifting out data on the SO pin (as shown in Figure 10). Sequentially stored data can be read out by simply continuing to run the clock. The internal address pointer is automatically incremented to the next higher address as data is shifted out. After reaching the highest memory address, the address counter "rolls over" to the lowest memory address, and the read cycle can be continued indefinitely. The read operation is terminated by taking CS high. Read Status Register To read the status register, the host simply sends a RDSR command. After receiving the last bit of the command, the CAT15008/16 will shift out the contents of the status register on the SO pin (Figure 11). The status register may be read at any time, including during an internal write cycle.
