Overview
The M95040-WDW6TP is an electrically erasable programmable memory (EEPROM) device produced by STMicroelectronics. It is part of the M950x0 series, which includes devices with 1, 2, and 4 Kbit of EEPROM memory. The M95040-WDW6TP specifically offers 4 Kbit (512 x 8 bits) of memory, accessible through the Serial Peripheral Interface (SPI) bus. This device operates within a supply voltage range of 2.5 V to 5.5 V and is designed to function over an ambient temperature range of -40 °C to +85 °C. It is packaged in a TSSOP-8L package, which is RoHS-compliant and halogen-free.
