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 VCC 2.7V - 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.
