NOTE: Pins designated as "NC" are typically unbonded pins. 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.

General Description
NM93C46 is a 1024-bit CMOS non-volatile EEPROM organized as 64 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 compat ible to many of standard Microcontrollers and Microprocessors. There are 7 instructions implemented on the NM93C46 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 NM93C46 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 consid erations.

Features
■ Wide VCC 2.7V - 5.5V
■ 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
■ Endurance: 1,000,000 data changes
■ Packages available: 8-pin SO, 8-pin DIP, 8-pin TSSOP
