NM93C06L/C46L/C56L/C66L

256-/1024-/2048-/4096-Bit Serial EEPROM

with Extended Voltage (2.7V to 5.5V)

(MICROWIRE^TMBus Interface)

General Description

The

Features

2.7V to 5.5V operation in all modes

NM93C06L/C46L/C56L/C66L

devices

are

256/1024/2048/4096 bits, respectively, of non-volatile

electrically erasable memory divided into 16/64/128/256 x

16-bit registers (addresses). The NM93CxxL Family func-

tions in an extended voltage operating range, requires only

a single power supply and is fabricated using National Semi-

conductor’s floating gate CMOS technology for high reliabili-

ty, high endurance and low power consumption. These de-

vices are available in both SO and TSSOP packages for

small space considerations.

Typical active current of 100 mA; Typical standby

current of 1 mA

No erase required before write

Reliable CMOS floating gate technology

MICROWIRE compatible serial I/O

Self-timed programming cycle

Device status during programming mode

40 years data retention

Endurance: 10 data changes

The EEPROM Interfacing is MICROWIRE compatible for

simple interface to standard microcontrollers and micro-

processors. There are 7 instructions that control these de-

vices: Read, Erase/Write Enable, Erase, Erase All, Write,

Write All, and Erase/Write Disable. The ready/busy status

is available on the DO pin during programming.

Packages available: 8-pin SO, 8-pin DIP, and 8-pin

TSSOP
