25AA02UID - 2K SPI Bus Serial EEPROM

Description

The Microchip Technology Inc.

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.

Features

  • Preprogrammed 32-Bit Serial Number: - Unique across all UID-family EEPROMs - Scalable to 48-bit, 64-bit, 128-bit, 256-bit, and other lengths.
  • 10 MHz max. Clock Frequency.
  • Low-Power CMOS Technology: - Max. write current: 5 mA at 5.5V - Read current: 5 mA at 5.5V, 10 MHz - Standby current: 1 A at 2.5V.
  • 256 x 8-Bit Organization.
  • Write Page mode (up to 16 bytes).
  • Sequential Read.
  • Self-Timed Erase and Write Cycles (5 ms max. ).
