NM93C56 2048-Bit Serial CMOS EEPROM (MICROWIRE™ Synchronous Bus) General Description Features NM93C56 is a 2048-bit CMOS non-volatile EEPROM organized as 128 x 16-bit array. This device features MICROWIRE interface which is a 4-wire serial bus with chipselect (CS), clock (SK), data input (DI) and data output (DO) signals. This interface is compatible to many of standard Microcontrollers and Microprocessors. There are 7 instructions implemented on the NM93C56 for various Read, Write, Erase, and Write Enable/Disable operations. This device is fabricated using Fairchild Semiconductor floating-gate CMOS process for high reliability, high endurance and low power consumption. ■ Wide VCC 2.7V - 5.5V “LZ” and “L” versions of NM93C56 offer very low standby current making them suitable for low power applications. This device is offered in both SO and TSSOP packages for small space considerations. ■ Endurance: 1,000,000 data changes ■ Typical active current of 200µA 10µA standby current typical 1µA standby current typical (L) 0.1µA standby current typical (LZ) ■ No Erase instruction required before Write instruction ■ Self timed write cycle ■ Device status during programming cycles ■ 40 year data retention ■ Packages available: 8-pin SO, 8-pin DIP, 8-pin TSSOP Functional Diagram VCC CS INSTRUCTION DECODER CONTROL LOGIC AND CLOCK GENERATORS SK DI INSTRUCTION REGISTER HIGH VOLTAGE GENERATOR AND PROGRAM TIMER ADDRESS REGISTER DECODER EEPROM ARRAY 16 READ/WRITE AMPS VSS 16 DATA IN/OUT REGISTER 16 BITS DO © 2000 Fairchild Semiconductor International NM93C56 Rev.

However some of them are bonded for special testing purposes. Hence if a signal is applied to these pins, care should be taken that the voltage applied on these pins does not exceed the VCC applied to the device. This will ensure proper operation.
