NM93CS46

(MICROWIRE™ Bus Interface) 1024-Bit Serial EEPROM

with Data Protect and Sequential Read

General Description

Features

NM93CS46 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.

NM93CS46 offers programmable write protection to the memory

array using a special register called Protect Register. Selected

memory locations can be protected against write by programming

this Protect Register with the address of the first memory location

to be protected (all locations greater than or equal to this first

addressarethenprotectedfromfurtherchange). Additionally, this

address can be “permanently locked” into the device, making all

future attempts to change data impossible. In addition this device

features “sequential read”, by which, entire memory can be read

in one cycle instead of multiple single byte read cycles. There are

10 instructions implemented on the NM93CS46, 5 of which are for

memory operations and the remaining 5 are for Protect Register

operations. This device is fabricated using Fairchild Semiconduc-

torfloating-gateCMOSprocessforhighreliability,highendurance

and low power consumption.

I Wide V_CC2.7V - 5.5V

I Programmable write protection

I Sequential register read

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

“LZ” and “L” versions of NM93CS46 offer very low standby current

makingthemsuitableforlowpowerapplications.Thisdeviceisoffered

in both SO and TSSOP packages for small space considerations.
