Product details
Overview
AT25PE80-SSHN-T from Adesto Technologies (now part of Dialog Semiconductor, acquired by Renesas) is an 8-Mbit serial Flash memory with dual SRAM buffers, SPI interface, and RapidS™ high-speed operation. It delivers up to 85 MHz clock rate, 6 ns clock-to-output time, and supports page sizes of 256 or 264 bytes. Designed for continuous data streaming in voice, image, and firmware storage applications, it enables interleaved buffer writes during main memory reprogramming.
For engineers reviewing the AT25PE80-SSHN-T datasheet, AT25PE80-SSHN-T pinout, AT25PE80-SSHN-T application, or AT25PE80-SSHN-T equivalent, key selection criteria include its dual-buffer architecture, ultra-low 300 nA deep power-down current, flexible erase granularity (page/sector/block/chip), JEDEC-compliant ID read, and support for SPI modes 0 and 3 across 1.7–3.6 V supply.
Technical Context
The AT25PE80-SSHN-T implements a sequential-access DataFlash®-Lite architecture with two independent 256/264-byte SRAM buffers enabling concurrent receive-and-program operation. Its internal address counter supports wraparound reads across page boundaries without delay, and all program/erase cycles are self-timed with status register monitoring (RDY/BUSY, EPE).
It uses a 3-wire SPI interface (CS, SCK, SI/SO) with WP and RESET pins for hardware write protection and reset control. Memory organization comprises 4,096 pages (256/264 bytes each), 128-byte security register with factory-unique ID, and sector protection register independent of software control.

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-T | 4 Mbit density, same SOIC-8 package, 104 MHz max clock, no dual buffers | Lacks interleaved buffer architecture; unsuitable for continuous streaming with concurrent writes | Select when lower density and higher clock speed suffice, and buffer concurrency is not required |
| W25Q80DVSSIQ | 8 Mbit, SOIC-8, Quad SPI capable, 104 MHz, no dedicated SRAM buffers | Supports QPI for bandwidth scaling but lacks hardware-managed dual buffers for seamless streaming | Choose for systems needing quad I/O expansion or faster random access; avoid where ping-pong buffering is critical |
Compared with AT25PE80-SSHN-T, the AT25SF041-SSHN-T offers higher clock speed but half the capacity and no dual buffers, while the W25Q80DVSSIQ provides quad interface flexibility but requires software-managed buffering - neither replicates the hardware-accelerated concurrent read/write capability central to AT25PE80-SSHN-T's streaming use cases.

FAQ
What is the maximum operating frequency of the AT25PE80-SSHN-T?
The AT25PE80-SSHN-T supports a maximum serial clock (SCK) frequency of 85 MHz under RapidS™ high-frequency read mode (1Bh opcode). This applies to continuous array reads at full speed; other commands and conditions may specify lower limits (e.g., fCAR2 = 33 MHz for 03h opcode, fCAR3 = 8 MHz for 01h low-power read). All timing values are validated across the full industrial temperature range (−40°C to +85°C) and 1.7–3.6 V supply.
Does the AT25PE80-SSHN-T support both 256-byte and 264-byte page sizes?
Yes, the AT25PE80-SSHN-T supports user-configurable page size: 256 bytes is the default, and 264 bytes is a customer-selectable option. The selected page size affects address bit allocation (20-bit vs. 21-bit addressing), dummy byte count in command sequences, and buffer addressing (BFA7–BFA0 vs. BFA8–BFA0). Both configurations maintain identical 4,096-page organization and dual-buffer functionality.
How does the dual-buffer architecture of the AT25PE80-SSHN-T improve system performance?
The AT25PE80-SSHN-T integrates two independent 256/264-byte SRAM buffers that allow simultaneous data reception via SI while reprogramming the main memory array. This eliminates write stalls during continuous data streams - for example, one buffer accepts new audio samples while the other transfers data to flash. Interleaving between buffers enables sustained throughput without CPU intervention or external RAM buffering.
What power-saving modes does the AT25PE80-SSHN-T offer, and what are their typical currents?
The AT25PE80-SSHN-T offers three low-power states: Standby (25 µA typical), Deep Power-Down (5 µA typical), and Ultra-Deep Power-Down (300 nA typical). Ultra-deep mode disables internal circuitry except for wake-up detection on CS, making it ideal for battery-powered devices requiring multi-year shelf life. All modes retain full memory contents and resume operation within microseconds upon CS assertion.
Is the AT25PE80-SSHN-T pin-compatible with standard 8-lead SOIC SPI Flash devices?
Yes, the AT25PE80-SSHN-T uses a standard 8-lead SOIC (0.208" wide) package with industry-standard SPI pinout: CS, SO, WP, GND, VCC, RESET, SCK, SI. Pin functions and electrical characteristics comply with JEDEC MS-012, enabling drop-in replacement in existing layouts - provided the host firmware supports its RapidS™ opcodes, dual-buffer commands, and optional 264-byte page mode.
