NM93CS46 (MICROWIRE Bus Interface) 1024-Bit Serial EEPROM

with Data Protect and Sequential Read

February 2000

NM93CS46

(MICROWIRE™ Bus Interface) 1024-Bit Serial EEPROM

with Data Protect and Sequential Read

General Description

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

address are then protected from further change). 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-

tor floating-gate CMOS process for high reliability, high endurance

and low power consumption.

“LZ” and “L” versions of NM93CS46 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.
