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 R W bit are defined in one single byte, instead of two (or three) bytes for the standard I 2C protocol.
