Product details
Overview
SST26VF080A-80E/MF from Microchip Technology is an 8-Mbit Serial Quad I/O™ (SQI™) Flash memory IC supporting both SPI and 4-bit multiplexed SQI protocols, operating at up to 80 MHz (2.3V–3.6V), with uniform 4-Kbyte sectors, 32/64-Kbyte overlay blocks, and OTP 2-Kbyte Security ID. It targets embedded firmware storage in space-constrained industrial and automotive systems.
For engineers reviewing the SST26VF080A-80E/MF datasheet, SST26VF080A-80E/MF pinout, SST26VF080A-80E/MF application, or SST26VF080A-80E/MF equivalent, key selection considerations include its dual-mode interface (SPI/SQI), 80 MHz max clock under extended temperature (−40°C to +125°C), AEC-Q100 qualification, WDFN-8 and SOIC-8 package options, and hardware/software write protection with volatile lock-down capability.
Technical Context
The SST26VF080A-80E/MF implements a six-wire, 4-bit I/O interface using SIO[3:0] pins for command/address/data multiplexing in SQI mode, enabling quadrupled throughput versus traditional SPI at identical clock frequency. It supports Mode 0 and Mode 3 clock polarity/idle states and retains full backward compatibility with standard SPI x1/x2/x4 commands upon power-up reset.
Its SuperFlash® technology features split-gate cells and thick-oxide tunneling injectors, delivering 100,000 program/erase cycles and >100 years data retention. The device integrates dedicated registers - STATUS (with BUSY, WEL, BP0–BP3, BPL bits) and Configuration (with IOC, VLP, WPEN, RSTHLD bits) - to manage protocol configuration, block protection, security ID locking, and suspend/resume operations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8-Mbit SPI-only (no SQI), 104 MHz max (3.0V), SOIC-8 only, no AEC-Q100 qualification, no Security ID | Lacks SQI bandwidth boost and automotive qualification; suitable for cost-sensitive consumer/non-automotive industrial use | Select when SQI interface and AEC-Q100 are unnecessary and lowest unit cost is primary requirement |
| Cypress S25FL080K0XMFI010 | 8-Mbit SPI/SQI, 133 MHz max (3.0V), WSON-8 package, AEC-Q100 Grade 2 (−40°C to +105°C), no OTP Security ID | Higher speed but narrower temperature range; lacks factory-unique ID for secure boot binding | Select when >80 MHz read throughput is required and extended +125°C operation is not needed |
Compared with SST26VF080A-80E/MF, W25Q80DVSSIG offers lower cost but forfeits SQI performance, automotive qualification, and security features; S25FL080K0XMFI010 delivers higher clock speed but sacrifices +125°C operation and hardware-enforced device identity - making SST26VF080A-80E/MF the sole option meeting full AEC-Q100 Grade 1, SQI bandwidth, and OTP Security ID requirements simultaneously.

FAQ
What interface protocols does the SST26VF080A-80E/MF support?
The SST26VF080A-80E/MF supports both traditional SPI (x1/x2 modes) and Serial Quad I/O™ (SQI) protocol. It powers up in SPI mode by default; the IOC bit in the Configuration register must be set to enable SQI mode. SQI uses SIO[3:0] for bidirectional command/address/data transfer, achieving up to 4× bandwidth versus SPI at the same clock frequency. SST26VF080A-80E/MF maintains full command-set compatibility with legacy SPI flash devices.
Does the SST26VF080A-80E/MF meet AEC-Q100 requirements for automotive use?
Yes, the SST26VF080A-80E/MF is AEC-Q100 qualified for Grade 1 (−40°C to +125°C), covering HTOL, temperature cycling, ESD, and parametric testing per the AEC specification. This qualification validates its suitability for automotive instrument clusters, body control modules, and ADAS subsystems where extended temperature operation and long-term reliability are mandatory. SST26VF080A-80E/MF is explicitly listed as AEC-Q100 qualified in its official datasheet DS20006203B.
How does the Security ID feature work on the SST26VF080A-80E/MF?
The SST26VF080A-80E/MF includes a 2-Kbyte Security ID (Sec ID) with two segments: a factory-programmed, unchangeable 128-bit unique identifier and a user-programmable area. The PSID command writes to the user area; the LSID command permanently locks both segments against further writes. Once locked, the SEC bit in the Configuration register becomes '1' and cannot be reset. SST26VF080A-80E/MF uses this for secure boot binding and device authentication in regulated applications.
What is the maximum clock frequency supported by the SST26VF080A-80E/MF at 2.3V–3.6V?
At 2.3V–3.6V supply, the SST26VF080A-80E/MF supports a maximum clock frequency of 80 MHz across both Industrial (−40°C to +85°C) and Extended (−40°C to +125°C) temperature ranges. This is specified in the official datasheet DS20006203B, page 1. At 2.7V–3.6V, it achieves 104 MHz - but only within the Industrial temperature range. SST26VF080A-80E/MF maintains full functionality and timing compliance at 80 MHz under extended +125°C operation.
Can the SST26VF080A-80E/MF perform simultaneous read and write operations?
No, the SST26VF080A-80E/MF does not support true concurrent read/write. However, it provides Write-Suspend functionality: an active program or erase operation can be paused using the WRSU command to allow immediate read access to other memory regions. After servicing the read, WRRE resumes the suspended operation. This enables deterministic latency handling in real-time systems without requiring external buffering. SST26VF080A-80E/MF implements this via internal state machine arbitration, not hardware parallelism.
