Microchip Technology 25AA02UID
25AA02UID is a 2 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) with a preprogrammed, 32-bit unique ID. The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines.| Part No. | 25AA02UID |
