AT25M02-SSHM-B: A 2-Mbit Serial EEPROM Memory Chip from Microchip Technology

In the realm of non-volatile memory solutions, serial EEPROMs remain a fundamental component for storing critical data in a vast array of electronic systems. The AT25M02-SSHM-B from Microchip Technology stands out as a robust and reliable 2-megabit solution, engineered to meet the demanding requirements of modern applications. This chip exemplifies the integration of high density, exceptional reliability, and low-power operation in a compact package.

Housed in an 8-lead SOIC package, the AT25M02-SSHM-B offers a storage capacity of 2 Mbits, organized as 262,144 bytes. It communicates via the ubiquitous Serial Peripheral Interface (SPI), enabling high-speed data transfer with a clock frequency of up to 85 MHz. This makes it suitable for applications requiring rapid read and write operations, from industrial automation and automotive systems to consumer electronics and smart meters.

A key feature of this memory chip is its advanced hardware-based data protection. It includes a software-controlled write disable pin and a dedicated write protect (`WP`) pin, allowing the system to prevent accidental modifications to the memory content. Furthermore, the device supports block-wise protection, where sections of the memory array can be locked to become read-only, safeguarding firmware or calibration data from corruption.

The device is designed for low-power consumption, a critical attribute for battery-powered and energy-sensitive applications. It supports a wide voltage range from 1.7V to 3.6V, ensuring compatibility with various logic levels and facilitating design-in into low-voltage systems. Its endurance is specified at over 1,000,000 write cycles per sector, and it offers a data retention period of up to 100 years, guaranteeing long-term data integrity.

In summary, the AT25M02-SSHM-B is a versatile and high-performance serial EEPROM that provides a dependable foundation for data storage needs.
