5V for M2201V version HARDWARE WRITE CONTROL 100 KBIT TRANSFER RATE BYTE WRITE PAGE WRITE (up to 4 BYTES) SELF TIMED PROGRAMMING CYCLE AUTOMATIC ADDRESS INCREMENTING ENHANCED ESD/LATCH UP 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 STMicroelectronics’s Hi-Endurance Advanced CMOS technology which guarantees a data retention of 100 years at 55°C.
The M2201 is available in Plastic Dual-in-Line, Plastic Small Outline and Thin Shrink Small Outline 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 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.
