DESCRIPTION

The M2201 is a simplified 2-wire bus 1 Kbit electri-

cally erasable programmable memory (EEPROM),

organized as 128 x8 bits. It is manufactured in

STMicroelectronics’s Hi-Endurance Advanced

CMOS technology which guarantees a data reten-

tion of 100 years at 55

°C.

The M2201 is available in Plastic Dual-in-Line,

Plastic Small Outline and Thin Shrink Small Out-

line packages.

The memory is compatible with a two wire serial

interface which uses a bi-directional data bus and

serial clock. Read and write operations are initi-

ated by a START condition generated by the bus

master and ended by a STOP condition.

Address bits and RW bit are defined in one single

byte, instead of two (or three) bytes for the standard

I2C protocol.
