NM93C06 256-Bit Serial CMOS EEPROM (MICROWIRETM Synchronous Bus) February 2000 NM93C06 256-Bit Serial CMOS EEPROM (MICROWIRE™ Synchronous Bus) General Description NM93C06 is a 256-bit CMOS non-volatile EEPROM organized as 16 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 NM93C06 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. “LZ” and “L” versions of NM93C06 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. Features I Wide VCC 2.7V - 5.5V I Typical active current of 200µA 10µA standby current typical 1µA standby current typical (L) 0.1µA standby current typical (LZ) I No Erase instruction required before Write instruction I Self timed write cycle I Device status during programming cycles I 40 year data retention I Endurance: 1,000,000 data changes I Packages available: 8-pin SO, 8-pin DIP, 8-pin TSSOP Functional Diagram CS SK DI INSTRUCTION REGISTER VCC INSTRUCTION DECODER CONTROL LOGIC AND CLOCK GENERATORS ADDRESS REGISTER HIGH VOLTAGE GENERATOR AND PROGRAM TIMER DECODER EEPROM ARRAY 16 READ/WRITE AMPS 16 VSS DATA IN/OUT REGISTER 16 BITS DO DATA OUT BUFFER © 2000 Fairchild Semiconductor International NM93C06 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.
