1 / 12 page 1/12 DS.ST14C02C/9811V2 ST14C02C Memory Card IC 2 Kbit (256 x 8) Serial I2C Bus EEPROM s Single Supply Voltage (3 V to 5.5 V) s Two Wire I2C Serial Interface s BYTE and MULTBYTE WRITE (up to 4 Bytes) s PAGE WRITE (up to 8 Bytes) s BYTE, RANDOM and SEQUENTIAL READ Modes s Self-Timed Programming Cycle s Automatic Address Incrementing s Enhanced ESD/Latch-Up Behavior s 1 Million Erase/Write Cycles (minimum) s 10 Year Data Retention (minimum) DESCRIPTION This device is an electrically erasable programma- ble memory (EEPROM) fabricated with STMicroelectronics’s High Endurance, Advanced Polysilicon, CMOS technology. This guarantees an endurance typically well above one million Erase/Write cycles, with a data retention of 10 years. The memory operates with a power supply as low as 3 V. The device is available in wafer form (either sawn or unsawn) and in micromodule form (on film). The memory is compatible with the I2C standard. This is a two wire serial interface that uses a bi-di- rectional data bus and serial clock. The memory carries a built-in 7-bit unique Device Type Identifi- er code (1010000) in accordance with the I2C bus definition. Only one memory can be attached to each I2C bus. Figure 1.
