Product details
Overview
SST26VF080A-104I/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 space-constrained applications. It operates from a single 2.3V–3.6V supply, supports 104 MHz SPI and SQI read speeds (industrial grade), features uniform 4-Kbyte sectors and 32/64-Kbyte overlay blocks, and includes OTP Security ID and hardware write protection - deployed in industrial control firmware storage and boot code retention.
For engineers reviewing the SST26VF080A-104I/SN datasheet, SST26VF080A-104I/SN pinout, SST26VF080A-104I/SN application, or SST26VF080A-104I/SN equivalent, key selection considerations include quad-I/O burst performance at 104 MHz, 4-Kbyte sector erase granularity, integrated security ID programmability, industrial temperature range (–40°C to +85°C), and WDFN/SOIC package compatibility with legacy SPI designs.
Technical Context
The SST26VF080A-104I/SN implements a six-wire, 4-bit multiplexed serial interface supporting both traditional SPI (x1/x2) and enhanced SQI (x4) protocols with Mode 0 and Mode 3 clock polarity compatibility. Its SuperFlash® split-gate CMOS technology enables fast 20 ms sector erase and 256-byte page programming with <15 µA standby current.
It integrates dual-mode pin mapping: SIO[3:0] serve as quad data I/O in SQI mode (enabled via EQIO command), while defaulting to SI/SO/WP#/HOLD# functions in SPI mode. The RST#/HOLD#/SIO3 pin is configurable via nonvolatile RSTHLD bit, and hardware write protection is enabled only when WPEN=1 and IOC=0 - ensuring deterministic behavior across power cycles.

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, 104 MHz SPI-only (no SQI), 3.3V only, no OTP Security ID | Lacks quad I/O bandwidth and hardware-secured identity - suitable for cost-sensitive SPI-only designs | Select when SQI interface and Security ID are not required; verify 3.3V-only supply compatibility |
| Cypress S25FL008KAGMFI011 | 8 Mbit, 104 MHz, supports Octal DTR mode, no OTP ID, different status register map | Higher pin count (16-pin SOIC), supports faster octal mode but requires controller support - no direct pinout match | Choose for future-proofing with octal interface; requires PCB redesign and driver adaptation |
Compared with SST26VF080A-104I/SN, W25Q80DVSSIG offers lower cost but sacrifices SQI bandwidth and security features, while S25FL008KAGMFI011 provides higher interface flexibility at the expense of package size and firmware porting effort - SST26VF080A-104I/SN uniquely balances industrial-grade reliability, compact 8-pin footprint, and built-in security in a single solution.

FAQ
What is the maximum clock frequency supported by SST26VF080A-104I/SN in SQI mode?
The SST26VF080A-104I/SN supports up to 104 MHz in SQI mode when operated within the 2.7V–3.6V supply range and industrial temperature conditions (–40°C to +85°C). This enables sustained 416 MB/s effective throughput using its 4-bit multiplexed I/O interface. Frequency drops to 80 MHz under 2.3V–3.6V operation or in extended temperature ranges, as specified in DS20006203B.
Does SST26VF080A-104I/SN support both SPI and SQI protocols simultaneously?
No, SST26VF080A-104I/SN does not operate in both SPI and SQI modes simultaneously. It powers up in SPI mode (SI/SO/WP#/HOLD# pin assignment) and transitions to SQI mode only after issuing the Enable Quad I/O (EQIO, 0x38) command. The IOC bit in the Configuration register must be set to '1' to activate SIO[3:0] for quad I/O; reverting to SPI requires RSTQIO (0xFF) or hardware reset.
How is hardware write protection implemented on SST26VF080A-104I/SN?
Hardware write protection on SST26VF080A-104I/SN is enabled only when three conditions are met: the WP# pin is driven low, the IOC bit = 0 (SPI mode), and the WPEN bit = 1 (nonvolatile, set via WRSR). When active, it locks the BPL bit and prevents modification of BP0–BP3 in the STATUS register. The factory default has WPEN = 0, so WP# is disabled until explicitly configured.
What is the purpose and structure of the Security ID in SST26VF080A-104I/SN?
The SST26VF080A-104I/SN includes a 2-Kbyte Security ID (Sec ID) with two segments: a factory-programmed, unchangeable 128-bit unique identifier and a user-programmable area. It is accessed via PSID (Program Security ID) and LSID (Lockout Security ID) commands. Once locked with LSID, no further writes are possible - enabling secure device binding for authentication and anti-counterfeiting in certified systems.
Can SST26VF080A-104I/SN perform erase or program operations while servicing read requests?
Yes, SST26VF080A-104I/SN supports write-suspend functionality. Using the WRSU (0xB0) command, an active program or erase operation can be suspended to allow immediate read access to other memory regions. Resume is executed with WRRE (0x30). This capability ensures deterministic latency for time-critical reads without aborting background writes - a key feature for real-time embedded systems.
