25LC040-I/SN - Microchip Function Overview

The 25LC040-I/SN is a 4kB serial Electrically Erasable Programmable Read-Only Memory (EEPROM) accessed via a simple serial peripheral interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of chip select, allowing the host to service higher priority interrupts. Also, write operations to the device can be disabled via the write-protect pin (WP).
Low-power CMOS technology
Write cycle time - 5ms maximum
Self-timed erase and write cycles
Block write protection - Protect none, 1/4, 1/2 or all of array
Built-in write protection
Power-on/off data protection circuitry

Write-protect pin
Sequential read
High reliability
Endurance - 1M cycles
Data retention - >200 years
ESD protection - 4000V
