25LC040AT-I/SN Description

Short technical summary and product information.

The Microchip Technology 25LC040AT-I/SN is a 4 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) accessed via a Serial Peripheral Interface (SPI) compatible serial bus. It features a maximum clock frequency of 10 MHz and operates within a voltage range of 2.5V to 5.5V.

 

This device offers a memory organization of 512 x 8 bits and supports write page mode with pages up to 16 bytes. It includes features such as sequential read, self-timed erase and write cycles (5 ms max.), and block write protection. Built-in write protection mechanisms include power-on/off data protection circuitry, a write enable latch, and a write-protect pin.

 

The 25LC040AT-I/SN is housed in an 8-SOIC package, suitable for surface mount applications. It operates within an industrial temperature range of -40°C to 85°C.

 

Key reliability features include an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. It also provides ESD protection greater than 4000V.
