Product details
Overview
AT25PE80-SSHN-B from Microchip Technology is an 8-Mbit serial Flash memory with SPI interface, RapidS™ high-speed operation up to 85 MHz, dual 256/264-byte SRAM buffers, and page/block/sector/chip erase granularity. It operates from 1.7V–3.6V and targets embedded firmware storage, voice/image buffering, and real-time data logging in industrial controllers.
For engineers reviewing the AT25PE80-SSHN-B datasheet, AT25PE80-SSHN-B pinout, AT25PE80-SSHN-B application, or AT25PE80-SSHN-B equivalent, key selection criteria include its 6 ns clock-to-output time, 300 nA ultra-deep power-down current, user-configurable 256/264-byte page size, and hardware write protection via WP pin.
Technical Context
The AT25PE80-SSHN-B implements a sequential-access DataFlash®-Lite architecture with two independent SRAM buffers enabling concurrent receive-and-reprogram operation. Its SPI interface supports modes 0 and 3, with four distinct continuous read opcodes (01h, 03h, 0Bh, 1Bh) optimized for low-power, standard, high-frequency, and legacy timing.
Internal self-timed erase/program cycles eliminate external voltage pumps; all operations use single-supply 1.7V–3.6V. The device integrates a 128-byte security register with factory-programmed unique ID and supports JEDEC-standard manufacturer/device ID readback for system identification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25SF041-SSHN-B | 4-Mbit density, same SOIC-8 package, identical pinout and SPI command set, but lacks RapidS™ 85 MHz mode (max 66 MHz) | Lower density suits simpler firmware images; no ultra-deep power-down (5 µA vs. 300 nA) | Select when cost-sensitive designs require proven compatibility but do not need 8-Mbit capacity or sub-µA sleep current |
| W25Q80DVSSIQ | 8-Mbit Quad SPI (QSPI) interface, 104 MHz max clock, 4-wire interface (IO0–IO3), different command set and security register layout | Higher bandwidth for graphics/UI assets; requires QSPI controller support and PCB layout changes | Select only if host MCU supports QSPI and system demands >10 MB/s burst reads; not drop-in compatible with AT25PE80-SSHN-B |
Compared with AT25PE80-SSHN-B, AT25SF041-SSHN-B offers lower cost and footprint compatibility but sacrifices density and ultra-low-power capability, while W25Q80DVSSIQ delivers higher bandwidth at the expense of interface redesign and firmware driver changes.

FAQ
What is the page size configuration for AT25PE80-SSHN-B?
The AT25PE80-SSHN-B supports user-configurable page size: 256 bytes is factory-default, while 264 bytes is a customer-selectable option enabled during manufacturing. Both configurations apply uniformly to main memory pages and SRAM buffers, and determine address bit allocation (20-bit vs. 21-bit addressing). This setting is fixed per unit and cannot be changed in-system.
Does AT25PE80-SSHN-B support Quad SPI (QSPI) interface?
No, AT25PE80-SSHN-B does not support Quad SPI. It implements a standard 3-wire SPI interface (CS, SCK, SI, SO) compatible with SPI modes 0 and 3. It lacks dedicated IO2/IO3 pins and QSPI-specific command opcodes. Designs requiring QSPI must select alternatives such as the W25Q80DV series, which are not pin- or firmware-compatible with AT25PE80-SSHN-B.
How does the dual-buffer architecture improve write performance in AT25PE80-SSHN-B?
The AT25PE80-SSHN-B uses two independent 256/264-byte SRAM buffers to decouple data ingestion from flash programming. While one buffer receives new data via SI, the other can simultaneously transfer its contents to main memory via Buffer-to-Page Program - eliminating write stalls and enabling continuous data streams. This architecture is essential for real-time logging and voice capture where gaps in recording are unacceptable.
What is the purpose of the RESET pin on AT25PE80-SSHN-B?
The RESET pin on AT25PE80-SSHN-B provides hardware-level abort capability: asserting it low terminates any active program or erase cycle and forces the internal state machine into idle mode. Unlike software reset commands, this action is immediate and unconditional. If unused, the pin must be externally held high; it is not internally pulled high in all operating states per datasheet guidance.
Is AT25PE80-SSHN-B compatible with legacy AT25DF081 designs?
AT25PE80-SSHN-B is not pin-compatible or command-compatible with AT25DF081. While both are 8-Mbit SPI Flash devices, AT25PE80-SSHN-B introduces RapidS™ timing, dual buffers, configurable page size, and updated status register bits. Migration requires firmware revision to accommodate new opcodes (e.g., 1Bh for high-speed read), address mapping changes, and buffer management logic - no transparent drop-in replacement exists.
