The Microchip AT45DB081E-SHN-T is an 8Mbit SPI serial Flash memory in an 8-SOIC package. It stores 8Mbit organized as 264 bytes per page across 4096 pages, accessed through a standard SPI bus at up to 85 MHz.
The 85 MHz SPI clock is the headline performance spec. The 8µs page-write and 4ms page-erase cycles are typical for this DataFlash family.
The part is ROHS3 compliant. Sourcing is through independent distribution.
Yes, the supply voltage range is 1.7V to 3.6V, so it operates directly on a 1.8V rail without a level shifter or external regulator.
The AT45DB081E-SSHN-T is functionally identical (same 8Mbit SPI Flash, same 85 MHz clock, same 1.7V-3.6V supply) but packaged in tube instead of Tape & Reel. The AT45DB081E-UUN-T is another variant with a different package format. All share the same die and performance specs.
No, the maximum supply voltage is 3.6V, and the SPI I/O thresholds track VCC. 5V logic levels exceed the absolute maximum ratings and will damage the device. Use a level translator if interfacing with a 5V host.
