High-Performance 2-Megabit Serial EEPROM Memory Solution with Microchip's AT24CM02-SSHD-B

In an era where data integrity and reliable non-volatile storage are paramount across industries, the demand for robust, high-density memory solutions continues to grow. Addressing this need, Microchip Technology's AT24CM02-SSHD-B stands out as a premier 2-megabit (256 KByte) serial EEPROM component, engineered for high-performance and reliability in demanding applications.

This memory solution is built on a highly reliable, advanced CMOS process, offering a versatile serial interface that supports both the industry-standard I²C (2-wire) protocol and the higher-speed SPI (4-wire) protocol. This dual-protocol support provides designers with exceptional flexibility, allowing the device to be easily integrated into diverse system architectures, whether for legacy upgrades or new designs. The AT24CM02-SSHD-B operates across a broad voltage range (1.7V to 5.5V), making it suitable for everything from low-power, battery-operated portable electronics to industrial automation systems.

A key feature of this EEPROM is its enhanced data endurance and retention. It is specified for 1,000,000 program/erase cycles per sector and offers data retention of over 100 years, ensuring long-term data integrity critical for automotive, medical, and industrial controls. The device also incorporates advanced hardware data protection mechanisms. A software write-protect pin allows the entire memory array or specific sectors to be locked, preventing accidental or malicious data overwrites and bolstering system security.

Furthermore, the AT24CM02-SSHD-B supports page write operations of up to 256 bytes, significantly improving write efficiency and reducing overall system power consumption. Its extended temperature range (-40°C to +125°C) ensures stable operation in harsh environments, a necessity for automotive and industrial applications. Housed in a space-saving 8-lead SOIC package, it offers a high-density memory solution without compromising board space.

ICGOODFIND: The Microchip AT24CM02-SSHD-B is a superior, high-density serial EEPROM that delivers exceptional performance, unparalleled flexibility with dual-interface support, and robust reliability for the most demanding embedded storage applications.
