Description

The AT24C256C-SSHL-B is a 256 Kbit (32 Kbyte) I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. It operates on a supply voltage range of 1.8V to 5.5V and supports high-speed I2C communication up to 1 MHz. The device features a 64-byte page write capability, allowing efficient data storage and retrieval.
With a 1 million write/erase cycle endurance and a data retention of over 100 years, it is ideal for applications requiring non-volatile memory, such as configuration settings, calibration data, or user information storage in embedded systems.
The AT24C256C-SSHL-B is housed in a small, 8-pin SOIC package (SSOP), making it suitable for space-constrained designs. Additionally, it includes multiple address lines to allow for interfacing with up to eight devices on the same bus. This makes it versatile for various applications, including consumer electronics, industrial automation, and automotive systems.
