D.1 March 1999 © 1999 Fairchild Semiconductor Corporation NM25C160 16K-Bit Serial CMOS EEPROM (Serial Peripheral Interface (SPI) Synchronous Bus) General Description The NM25C160 is a 16,384-bit CMOS EEPROM with an SPI compatible serial interface. The NM25C160 is designed for data storage in applications requiring both non-volatile memory and in- system data updates. This EEPROM is well suited for applications using the 68HC11 series of microcontrollers that support the SPI interface for high speed communication with peripheral devices via a serial bus to reduce pin count. The NM25C160 is imple- mented in Fairchild Semiconductor’s floating gate CMOS process that provides superior endurance and data retention. The serial data transmission of this device requires four signal lines to control the device operation: Chip Select (CS), Clock (SCK), Data In (SI), and Serial Data Out (SO). All programming cycles are completely self-timed and do not require an erase before WRITE. BLOCK WRITE protection is provided by programming the STA- TUS REGISTER with one of four levels of write protection. Additionally, separate WRITE enable and WRITE disable instruc- tions are provided for data protection. Hardware data protection is provided by the WP pin to protect against inadvertent programming. The HOLD pin allows the serial communication to be suspended without resetting the serial sequence.
