NM25C160  
16K-Bit Serial CMOS EEPROM  
(Serial Peripheral Interface (SPI) Synchronous Bus)  
General Description  
Features  
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-  
systemdataupdates. ThisEEPROMiswellsuitedforapplications  
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.  
2.1 MHz clock rate @ 2.7V to 5.5V  
16,384 bits organized as 2,048 x 8  
Multiple chips on the same 3-wire bus with separate chip  
select lines  
Self-timed programming cycle  
Simultaneous programming of 1 to 16 bytes at a time  
Status register can be polled during programming to monitor  
READY/BUSY  
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.  
Write Protect (WP) pin and write disable instruction for both  
hardware and software write protection  
Block write protect feature to protect against accidental  
writes  
Endurance: 1,000,000 data changes  
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.  
Data retention greater than 40 years  
Packages available: 8-pin DIP, 8-pin SO, or 8-pin TSSOP  
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.
