The STMicroelectronics M93C56-WDW6TP is an EEPROM 2K (256x8 or 128x16) part. This product is a low-voltage, serial full 8-bit Electrically Erasable Programmable Read-Only Memory (EEPROM) that is organized into two banks of 1K each. The device is programmed and erased using low voltage serial data transfers. It provides greater security, efficient and reliable code storage, and flexibility to optimize applications. The M93C56-WDW6TP operates down to 1.7V and has an extended operating temperature range of -20°C to +125°C. It also features a fast data eeprom write cycle time of 1.5ms for 64 bytes, a low power standby mode, and 8 bytes of page write or 128 bytes of byte write.
