NM25C020 2K-Bit Serial CMOS EEPROM (Serial Periphrial Interface (SPI) Synchronous Bus) March 1999 NM25C020 2K-Bit Serial CMOS EEPROM (Serial Peripheral Interface (SPI) Synchronous Bus) General Description Features The NM25C020 is a 2048-bit CMOS EEPROM with an SPIn2.1 MHz clock rate @ 2.7V to 5.5V compatible serial interface. The NM25C020 is designed for datan2048 bits organized as 256 x 8 storage in applications requiring both non-volatile memory and in- nMultiple chips on the same 3-wire bus with separate chip system data updates. This EEPROM is well suited for applications select lines using the 68HC11 series of microcontrollers that support the SPI nSelf-timed programming cycle interface for high speed communication with peripheral devices via a serial bus to reduce pin count. The NM25C020 is imple-nSimultaneous programming of 1 to 4 bytes at a time mented in Fairchild Semiconductor’s floating gate CMOS process nStatus register can be polled during programming to monitor that provides superior endurance and data retention. READY/BUSY The serial data transmission of this device requires four signalnWrite Protect (WP) pin and write disable instruction for both lines to control the device operation: Chip Select (CS), Clock hardware and software write protection (SCK), Data In (SI), and Serial Data Out (SO). All programming nBlock write protect feature to protect against accidental cycles are completely self-timed and do not require an erase writes before WRITE. nEndurance: 1,000,000 data changes BLOCK WRITE protection is provided by programming the STA- nData retention greater than 40 years TUS REGISTER with one of four levels of write protection. nPackages available: 8-pin DIP, 8-pin SO, or 8-pin TSSOP 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.
