The S-24CS01A, S-24CS02A, S-24CS04A, S24CS08A is a 2-wired, low power and wide range operation 1k bit, 2k bit, 4k bit and 8k bit E2PROM organized as 128 words × 8 bits, 256 words × 8 bits, 512 words × 8 bits and 1024 words × 8 bits in each. Page write and sequential read are available.

A CMOS serial EEPROM, also known as a CMOS EEPROM or simply a serial EEPROM, is a type of non-volatile memory device used to store small amounts of data that need to be retained even when power is removed. CMOS stands for Complementary Metal-Oxide-Semiconductor, which is a common semiconductor technology used in modern integrated circuits.


1. Non-Volatile Memory: Serial EEPROMs are non-volatile memory devices, meaning they retain data even when the power supply is disconnected. This makes them suitable for storing critical configuration data, calibration settings, or other information that should not be lost in the event of a power outage.

2. Serial Interface: These EEPROMs communicate with microcontrollers or other digital devices using a serial communication protocol, such as I2C (Inter-Integrated Circuit) or SPI (Serial Peripheral Interface). The serial interface simplifies integration into digital systems and allows for easy read and write operations.
