Microchip 1 MB Serial EEPROM 80 ns 20 MHz SPI Interface 8-Pin SOIC Package AT25M01-SSHM-B

Microchip AT25M01-SSHM-B is a high-performance 1 MB serial electrically erasable programmable read-only memory (EEPROM) engineered for diverse industrial and commercial applications requiring low-power, low-voltage, and fast memory solutions. It features a 131,072-word by 8-bit organization optimized for SPI interface communication supporting modes 0 and 3 up to 20 MHz clock frequency.

The device operates over a wide voltage range from 1.7 V (minimum) to 5.5 V (maximum) and provides fast random access times of 80 nanoseconds, enabling quick data retrieval. Data retention is guaranteed for 100 years with a robust endurance of more than one million erase/write cycles, making the product highly reliable for long-term use.

Microchip’s EEPROM includes flexible block write protection allowing selective protection of 1/4, half, or the entire memory area. Its low power consumption features include a maximum read current of 10 mA at 20 MHz, a write current of 7 mA at 5 V, and standby currents as low as 3 μA at 1.7 V, supporting energy-sensitive applications. The self-timed erase and write cycles complete within 5 milliseconds, enhancing operational efficiency.

Packaged in an industry-standard 8-pin SOIC surface mount form factor with a height of 1.5 mm, this EEPROM module supports easy integration in compact PCB designs. It is RoHS compliant and suited for operation in harsh environments with temperatures ranging from -40°C to 85°C, although it is not designed for automotive usage.

1,048,576 bits organized as 131,072 words of 8 bits. Fast 80 ns access time and supports SPI modes 0 and 3 up to 20 MHz. Operates at supply voltage range of 1.7 V to 5.5 V. Endurance of more than one million erase/write cycles.
