NM93C06 256-Bit Serial CMOS EEPROM (MICROWIRE™ Synchronous Bus) General Description Features NM93C06 is a 256-bit CMOS non-volatile EEPROM organized as Wide VCC 2.7V - 5.5V 16 x 16-bit array. This device features MICROWIRE interface
Typical active current of 200µA
which is a 4-wire serial bus with chipselect (CS), clock (SK), data
10µA standby current typical
input (DI) and data output (DO) signals. This interface is compat-
1µA standby current typical (L)
ible to many of standard Microcontrollers and Microprocessors.
0.1µA standby current typical (LZ)
There are 7 instructions implemented on the NM93C06 for various
No Erase instruction required before Write instruction
Read, Write, Erase, and Write Enable/Disable operations. This
device is fabricated using Fairchild Semiconductor floating-gate Self timed write cycle

Frequently Asked Questions
What is the operating voltage range for the EEPROM?
The recommended power supply voltage (VCC) ranges from 2.7V to 5.5V, depending on the specific version (L or LZ).
How reliable is this device for frequent writes?
It has an endurance of 1,000,000 data changes, making it suitable for low power applications.
What communication bus does the NM93C06 use?
It features a MICROWIRE synchronous bus with a 4-wire serial interface (CS, SK, DI, DO).
Does the EEPROM require prior instructions before being programmed?
No; Read, Write, Erase, and Write Enable/Disable operations do not require an Erase instruction first.
