25AA040/P Description

Short technical summary and product information.

The Microchip Technology 25AA040/P is a 4 Kbit serial Electrically Erasable PROM (EEPROM) that utilizes a Serial Peripheral Interface (SPI) compatible serial bus for communication. This device offers a memory organization of 512 x 8 bits and operates at a maximum clock frequency of 1 MHz.

 

Key electrical characteristics include a wide operating voltage range from 1.8V to 5.5V, a write current of 3 mA typical, a read current of 500 μA typical, and a low standby current of 500 nA typical. The write cycle time is a maximum of 5 ms. The device features built-in write protection mechanisms, including a write-protect pin and a write enable latch, and supports block write protection for portions of the array.

 

Packaged in an 8-pin PDIP (Plastic Dual In-line Package) with a 0.300" (7.62mm) body, the 25AA040/P is designed for through-hole mounting. It operates within an industrial temperature range of -40°C to +85°C. The EEPROM boasts high reliability with an endurance of 1M cycles and data retention exceeding 200 years, along with ESD protection greater than 4000V.
