Part number : 24C02WP
Functions : SERIAL 2K (256 x 8) EEPROM
Manufacturer : STMicroelectronics
This specification covers a range of 2K bits I2C bus EEPROM products, the ST24/25C02, the ST24C02R and ST24/25W02. In the text, products are referred to as ST24/25×02, where “x” is: “C” for Standard version and “W” for hardware Write Control version.
The ST24/25×02 are 2K bit electrically erasable programmable memories (EEPROM), organized as 256 x 8 bits. They are manufactured in SGS THOMSON’s Hi-Endurance Advanced CMOS technology which guarantees an endurance of one million erase/write cycles with a data retention of 40 years. The memories operate with a power supply value as low as 1.8V for the ST24C02R only.
Both Plastic Dual-in-Line and Plastic Small Outline packages are available.
