Microchip 1 MB SPI EEPROM 8-Pin SOIC, 80 ns Access Time, 1.7V to 5.5V Supply, AT25M01-SSHM-B

Microchip AT25M01-SSHM-B is a 1 MB SPI EEPROM featuring 8-pin SOIC package optimized for industrial and commercial use where low-power and low-voltage operation are critical. Operating between 1.7 V and 5.5 V, this EEPROM provides non-volatile memory organized as 128K by 8 bits, suitable for various embedded system applications.

This device supports SPI modes 0 and 3 with a maximum clock frequency of 20 MHz, providing rapid data access with a maximum random access time of only 80 ns. The internal self-timed erase and write cycles have a maximum duration of 5 milliseconds ensuring efficient memory operations without external timing circuitry.

Designed for industrial temperature ranges from -40°C to 85°C, the AT25M01-SSHM-B guarantees long data retention of up to 100 years and endurance of more than one million erase/write cycles, making it reliable for harsh environments and long-term applications.

Current consumption is minimized with a typical active current of 10 mA at 20 MHz and standby currents as low as 3 μA at 1.7 V. Block write protection features allow selective protection of memory segments enhancing data integrity and security.

Compact 8-pin SOIC surface-mount package simplifies integration into PCBs. Supports low supply voltages down to 1.7 V while withstanding up to 5.5 V maximum. Enhanced robustness for automotive and industrial standards except no automotive certification.

Ideal for data logging, configuration storage, and code storage in embedded systems.

This EEPROM is suitable for a wide range of industrial, commercial, and manufacturing applications requiring reliable, low-power non-volatile memory solutions. It is part of the AT25M0 series known for its performance and endurance.
