Product details
Overview
SST26VF080A-104I/MF from Microchip Technology is an 8-Mbit Serial Quad I/O™ (SQI™) Flash memory IC supporting dual-voltage operation (2.3V–3.6V), 104 MHz max clock frequency (industrial grade), uniform 4-Kbyte sectors, and hardware/software write protection. It serves as nonvolatile program/data storage in microcontroller boot loaders and firmware update modules.
For engineers reviewing the SST26VF080A-104I/MF datasheet, SST26VF080A-104I/MF pinout, SST26VF080A-104I/MF application, or SST26VF080A-104I/MF equivalent, key selection criteria include SQI/x4 SPI interface compatibility, 104 MHz read performance at 2.7–3.6 V, AEC-Q100 qualification for automotive use, and OTP Security ID support.
Technical Context
The SST26VF080A-104I/MF implements a six-wire SQI interface with multiplexed SIO[3:0] pins enabling 4-bit data transfer per clock cycle, achieving up to 4× throughput versus standard SPI at identical clock rates. It supports both SPI Mode 0 and Mode 3 timing, with configurable IOC bit switching between SPI and SQI protocols.
Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling to deliver 100,000 program/erase cycles and >100 years data retention. The device integrates dedicated registers - STATUS (R/W), CONFIGURATION (R/W), and OTP Security ID - with hardware-level protection via WP# and RESET#/HOLD# pin multiplexing.

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 (x1/x2), no SQI; 104 MHz max, same SOIC-8 package | Lacks quad I/O and Security ID; requires SPI controller with dual-I/O support only | Select when SQI bandwidth is unnecessary and cost optimization prioritizes mature SPI ecosystem compatibility |
| Cypress S25FL008K0XMFI010 | 8-Mbit HyperFlash-compatible; 133 MHz DDR interface; different command set and timing model | Requires HyperBus controller; not drop-in compatible; targets high-throughput code XIP applications | Choose for systems needing execute-in-place (XIP) with sub-50 ns random access - not for legacy SPI/SQI designs |
Compared with W25Q80DVSSIG, SST26VF080A-104I/MF delivers 4× interface bandwidth and integrated security; versus S25FL008K0XMFI010, it offers simpler SPI/SQI integration and automotive qualification but lower peak throughput.

FAQ
What voltage range does the SST26VF080A-104I/MF support for reliable operation?
The SST26VF080A-104I/MF operates across a single supply range of 2.3V to 3.6V. At 2.7V–3.6V, it achieves its rated 104 MHz maximum clock frequency for industrial-grade performance. The extended 2.3V minimum enables compatibility with brown-out tolerant systems and battery-backed operation, while maintaining full functionality including program, erase, and read commands.
Does the SST26VF080A-104I/MF support both SPI and SQI interfaces simultaneously?
No - the SST26VF080A-104I/MF defaults to SPI mode after power-on reset and requires explicit configuration via the EQIO command (0x38) to enter SQI mode. The IOC bit in the Configuration register must be set to '1' to enable SIO[3:0] as quad I/O lines. Once configured, SQI remains active until reset or RSTQIO command; simultaneous SPI/SQI operation is not supported.
How is write protection implemented on the SST26VF080A-104I/MF?
The SST26VF080A-104I/MF implements layered write protection: software-based via BP0–BP3 bits in the STATUS register (configurable per 4-Kbyte sector), hardware-based via the WP# pin (when WPEN=1 and IOC=0), and volatile lock-down via LDPS command. The BPL bit prevents modification of BP bits, while the OTP Security ID area can be permanently locked using LSID command - all mechanisms apply to SST26VF080A-104I/MF without external circuitry.
What is the purpose of the HOLD# and RESET# functions on the same pin of the SST26VF080A-104I/MF?
The SST26VF080A-104I/MF multiplexes HOLD# and RESET# on the same physical pin (pin 6 in SOIC/WDFN). Its function is determined by the RSTHLD bit in the Configuration register: RSTHLD=0 configures it as HOLD# (active-low pause of SPI transfers), while RSTHLD=1 configures it as RESET# (hardware reset trigger). This dual-role design conserves pins while preserving critical system-level control functions in space-constrained layouts.
Is the SST26VF080A-104I/MF qualified for automotive applications?
Yes - the SST26VF080A-104I/MF is explicitly AEC-Q100 qualified for automotive use. It meets stress test requirements for temperature cycling, humidity, and ESD robustness across the industrial temperature range (–40°C to +85°C), and is rated for operation in engine control units, ADAS modules, and infotainment systems where long-term reliability under thermal and electrical stress is mandatory. This qualification applies directly to the SST26VF080A-104I/MF part number.
