Product details
Overview
SST26VF080A-80E/SN from Microchip Technology is an 8-Mbit Serial Quad I/O™ (SQI™) Flash memory IC designed for high-speed, low-pin-count embedded storage in microcontroller-based systems. It supports dual-voltage operation (2.3V–3.6V), delivers up to 80 MHz clock frequency in extended temperature range, features uniform 4-Kbyte sectors and 32/64-Kbyte overlay blocks, and integrates One-Time-Programmable 2-Kbyte Security ID - used in industrial control firmware storage and secure boot applications.
For engineers reviewing the SST26VF080A-80E/SN datasheet, SST26VF080A-80E/SN pinout, SST26VF080A-80E/SN application, or SST26VF080A-80E/SN equivalent, key selection criteria include quad-I/O burst performance, hardware/software write protection granularity, 100,000-cycle endurance, AEC-Q100 qualification for automotive use, and WDFN-8 (6 mm × 5 mm) package compatibility with space-constrained PCB layouts.
Technical Context
The SST26VF080A-80E/SN implements a six-wire, 4-bit multiplexed serial interface supporting both legacy SPI (x1/x2) and high-throughput SQI protocols, with Mode 0 and Mode 3 clock polarity compatibility. Its SuperFlash® split-gate CMOS technology enables single-supply erase/program operations with 20 ms sector erase time and 256-byte page programming.
It integrates dual protection mechanisms: software-configurable block protection via STATUS register BP0–BP3 bits and hardware-level write protection using the WP# pin with configurable WPEN/IOC bits. The device also supports write-suspend, security ID locking, and hardware/software reset - all managed through dedicated command opcodes (e.g., 38H for EQIO, 8DH for LDPS, A5H for PSID).

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, SOIC-8 package only, no OTP Security ID | Lacks quad-I/O speed boost and hardware-rooted device identity; suitable for cost-sensitive non-secure designs | Select when SQI bandwidth and cryptographic ID are unnecessary and SOIC-8 footprint is required |
| Cypress S25FL008KAGMFI010 | 8-Mbit HyperFlash-compatible, 133 MHz DDR interface, 16-pin SOIC, no AEC-Q100 rating | Higher bandwidth but larger package and no automotive qualification; lacks integrated security ID | Select for high-throughput code XIP in industrial CPUs needing DDR interface, not automotive or secure boot use cases |
Compared with W25Q80DVSSIG and S25FL008KAGMFI010, the SST26VF080A-80E/SN uniquely combines AEC-Q100 qualification, OTP Security ID, SQI protocol flexibility, and WDFN-8 compactness - making it the only option qualified for secure, space-constrained automotive and industrial firmware storage where deterministic update latency and device identity are mandatory.

FAQ
What voltage range does the SST26VF080A-80E/SN support for read and write operations?
The SST26VF080A-80E/SN supports single-supply operation from 2.3V to 3.6V for both read and write functions. This dual-range capability enables interoperability with 2.5V and 3.0V system rails. At 2.3V–3.6V, maximum clock frequency is 80 MHz for industrial and extended temperature grades. The device maintains full command-set compatibility across this range without external level shifting.
Does the SST26VF080A-80E/SN support both SPI and SQI protocols, and how is mode switching handled?
Yes, the SST26VF080A-80E/SN supports backward-compatible SPI (x1/x2) and high-speed SQI (x4) protocols. After power-on reset, it defaults to SPI mode. To enable SQI, the host must issue the Enable Quad I/O (EQIO, 0x38) command and set the IOC bit in the Configuration register. Once configured, SIO[3:0] operate as multiplexed quad I/O lines - no hardware changes are needed beyond software initialization.
What is the purpose and behavior of the HOLD# pin on the SST26VF080A-80E/SN?
The HOLD# pin on the SST26VF080A-80E/SN temporarily suspends active SPI communication while preserving internal state and clock phase - allowing the host to service higher-priority tasks without aborting ongoing transfers. It operates only in SPI x1/x2 read mode (not in SQI mode) and requires CE# to remain low. When asserted, SO enters high-impedance; SI and SCK may be driven freely. The pin is enabled by default (IOC=0 at power-up).
How is write protection implemented on the SST26VF080A-80E/SN, and what levels of granularity are available?
The SST26VF080A-80E/SN implements dual-layer write protection: software-based via BP0–BP3 bits in the STATUS register (configurable down to 4-Kbyte sectors), and hardware-based via the WP# pin (when WPEN=1 and IOC=0). Block protection can lock upper 1/16 to full 8-Mbit array. The BPL bit prevents modification of BP bits, and the LDPS command enables volatile lock-down - ensuring firmware partitions remain immutable during runtime.
Is the SST26VF080A-80E/SN qualified for automotive applications, and what evidence supports this claim?
Yes, the SST26VF080A-80E/SN is explicitly AEC-Q100 qualified for automotive applications, as confirmed in the official Microchip datasheet DS20006203B. It meets Grade 3 requirements (-40°C to +125°C) and includes built-in reliability features such as 100,000-cycle endurance and >100-year data retention - validated for use in engine control units, body control modules, and ADAS systems where failure modes must be rigorously controlled.
