NM93C46A  
1K-Bit Serial CMOS EEPROM  
(MICROWIRE™ Synchronous Bus)  
General Description  
Features  
NM93C46A 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.  
This device offers a pin (ORG), using which, the user can select  
the format of the data (16-bit or 8-bit). If ORG is tied to GND, then  
8-bit format is selected, while if ORG is tied to VCC, then 16-bit  
format is selected. There are 7 instructions implemented on the  
NM93C46A for various Read, Write, Erase, and Write Enable/  
Disable operations. This device is fabricated using Fairchild  
Semiconductor floating-gate CMOS process for high reliability,  
high endurance and low power consumption.  
I Wide VCC 2.7V - 5.5V  
I User selectable organization  
x16 (ORG = 1)  
x8 (ORG = 0)  
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  
“LZ” and “L” versions of NM93C46A 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 consid-  
erations.  
I Endurance: 1,000,000 data changes  
I Packages available: 8-pin SO, 8-pin DIP, 8-pin TSSOP
