25AA040-I/SN Description

Short technical summary and product information.

The Microchip Technology 25AA040-I/SN is a 4 Kbit serial Electrically Erasable PROM (EEPROM). It utilizes a Serial Peripheral Interface (SPI) compatible serial bus for communication, requiring clock (SCK), data in (SI), and data out (SO) lines. Access is controlled via a Chip Select (CS) input.

 

This EEPROM features a memory organization of 512 x 8 bits and a memory size of 4 Kbit. It operates within a voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 1 MHz. The device has a write cycle time of 5ms and is designed for industrial applications with an operating temperature range of -40°C to 85°C.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) format, the 25AA040-I/SN is suitable for surface mount applications. Key features include low-power CMOS technology, with typical read current of 500 μA and standby current of 500 nA. It offers high reliability with an endurance of 1M cycles and data retention exceeding 200 years.
