## Description

The Microchip Technology 25C040SN is a 4 Kbit serial Electrically Erasable PROM (EEPROM) designed for efficient data storage and retrieval. It utilizes a standard Serial Peripheral Interface (SPI) compatible serial bus, requiring clock (SCK), data in (SI), and data out (SO) lines for communication. Device access is managed through a Chip Select (CS) input, and operations can be temporarily paused using the HOLD pin.

This EEPROM features a 512 x 8-bit organization with a page size of 16 bytes, facilitating efficient data writes. It supports a maximum clock frequency of 3 MHz for the 25C040 variant and operates within industrial temperature ranges of -40°C to +85°C. Key electrical characteristics include a typical read current of 500 μA and a standby current of 500 nA, contributing to its low-power CMOS technology.

The 25C040SN is available in PDIP, SOIC, and TSSOP packages, supporting surface mount applications. It offers high reliability with an endurance of 1M cycles and data retention exceeding 200 years. Built-in write protection mechanisms, including a write-protect pin and write enable latch, enhance data integrity.
