25AA02UIDT-I/OT Description

Short technical summary and product information.

The Microchip Technology 25AA02UIDT-I/OT is a 2 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) with a preprogrammed, 32-bit unique ID. It is accessed via a Serial Peripheral Interface (SPI) compatible serial bus, requiring clock (SCK), data in (SI), and data out (SO) lines, controlled by a Chip Select (CS) input. The device supports a maximum clock frequency of 10 MHz and operates within a voltage range of 1.8V to 5.5V.

 

This EEPROM features a 256 x 8-bit organization and supports write page mode with pages up to 16 bytes. It offers high reliability with an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. The operating temperature range is -40°C to 85°C.

 

The 25AA02UIDT-I/OT is available in a compact 6-lead SOT-23 package, suitable for surface mounting. It includes built-in write protection features such as power-on/off data protection circuitry, a write enable latch, and a write-protect pin. The device also supports block write protection, allowing for none, 1/4, 1/2, or all of the array to be protected.
