Logic Diagram DESCRIPTION The M2201 is a simplified 2-wire bus 1 Kbit electrically erasable programmable memory (EEPROM), organized as 128 x8 bits. It is manufactured in ST Microel ectro nics's Hi-Endurance Advanced CMOS technology which guarantees a data retention of 100 years at 55°C. Both Plastic Dual-in-Line and Plastic Small Outline packages are available. 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 initiated 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.
