Overview
The M34E02-FDW1TP is a 2-Kbit I2C-compatible EEPROM (Electrically Erasable PROgrammable Memory) produced by STMicroelectronics. This memory device is organized as 256 × 8 bits and is designed for serial presence detect (SPD) in DDR1, DDR2, and DDR3 memory modules. It operates with a supply voltage ranging from 1.7 V to 5.5 V and supports a clock frequency of up to 400 kHz. The device is backward compatible with the M34C02 and offers enhanced features such as permanent and reversible software data protection for the lower 128 bytes.
