NM93CS56 (MICROWIRE Bus Interface) 2048-Bit Serial EEPROM
with Data Protect and Sequential Read
February 2000
NM93CS56
(MICROWIRE™ Bus Interface) 2048-Bit Serial EEPROM
with Data Protect and Sequential Read
General Description
NM93CS56 is a 2048-bit CMOS non-volatile EEPROM organized
as 128 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.
NM93CS56 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 NM93CS56, 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 NM93CS56 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.
