Product details
Overview
SST26VF080AT-80E/SN from Microchip Technology is an 8-Mbit Serial Quad I/O™ (SQI™) Flash memory IC supporting dual-voltage operation (2.3V–3.6V), 80 MHz max clock frequency in extended temperature range (–40°C to +125°C), uniform 4-Kbyte sectors, and hardware/software write protection - deployed in embedded boot code storage and firmware update applications.
For engineers reviewing the SST26VF080AT-80E/SN datasheet, SST26VF080AT-80E/SN pinout, SST26VF080AT-80E/SN application, or SST26VF080AT-80E/SN equivalent, key selection criteria include SQI/x4 interface support, AEC-Q100 qualification, 2-Kbyte OTP Security ID, 100,000-program/erase endurance, and WDFN-8 (6 mm × 5 mm) package compatibility with space-constrained automotive and industrial control designs.
Technical Context
The SST26VF080AT-80E/SN implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) compatible with both SPI Mode 0/3 and SQI protocols, enabling quad-data-rate transfers without additional pins. Its SuperFlash® split-gate CMOS technology delivers faster erase (20 ms sector, 40 ms chip) and lower active current (15 mA @ 80 MHz) versus conventional NOR Flash.
It supports flexible memory protection via STATUS register BP0–BP2 bits, volatile lock-down (LDPS command), and hardware WP# pin control (enabled when IOC=0 and WPEN=1). The RST#/HOLD#/SIO3 pin is configurable via RSTHLD bit for reset or hold function, and the device ships with factory-default block protection enabled (BP0–BP2 = 111).

FAQ
What is the operating voltage range for SST26VF080AT-80E/SN?
The SST26VF080AT-80E/SN operates from a single 2.3V to 3.6V supply. This dual-voltage capability enables direct integration with both 2.5V and 3.3V system rails without level-shifting. The 80 MHz maximum clock frequency is specified across the full 2.3V–3.6V range under extended temperature conditions (–40°C to +125°C), ensuring consistent performance in automotive and industrial environments where rail voltage may vary.
Does SST26VF080AT-80E/SN support both SPI and SQI protocols?
Yes, the SST26VF080AT-80E/SN supports full backward compatibility with standard SPI (x1/x2 modes) and native Serial Quad I/O™ (SQI) protocol (x4 mode). After power-on reset, it defaults to SPI mode; the EQIO command (0x38) configures SIO[3:0] for quad I/O operation. Both Mode 0 and Mode 3 clock polarity/phasing are supported, and SQI quadruples effective data throughput at identical clock frequencies by using four bidirectional data lines.
What is the purpose of the Security ID feature in SST26VF080AT-80E/SN?
The SST26VF080AT-80E/SN includes a 2-Kbyte One-Time-Programmable (OTP) Security ID with two segments: a factory-programmed 128-bit unique identifier (immutable) and a user-programmable area. This enables device authentication, firmware binding, and anti-counterfeiting. The LSID command permanently locks the entire Security ID space, and neither segment can be erased - providing a hardware-rooted trust anchor essential for automotive and medical applications requiring traceability and secure boot.
How does write protection work on SST26VF080AT-80E/SN?
SST26VF080AT-80E/SN implements three-tiered write protection: (1) software-based via BP0–BP2 bits in the STATUS register to protect memory regions; (2) hardware-based using the WP# pin (enabled when IOC=0 and WPEN=1); and (3) volatile lock-down via LDPS command to prevent BP-bit modification. By default, BP0–BP2=111 protects the entire array after power-up. The BPL bit (bit 7) controls whether BP bits are writable, and WP# pin state determines if BPL can be altered - offering granular, layered security for firmware integrity.
Is SST26VF080AT-80E/SN qualified for automotive applications?
Yes, the SST26VF080AT-80E/SN is AEC-Q100 qualified (Grade 1) for operation from –40°C to +125°C ambient temperature. It meets stringent automotive reliability standards including HTOL, ESD, and thermal cycling. Its SuperFlash® technology ensures >100-year data retention at 125°C and 100,000 program/erase cycles - validated for use in engine control units, ADAS modules, and infotainment systems where long-term firmware integrity and environmental robustness are mandatory. The WDFN-8 package supports automated optical inspection (AOI) and reflow compatibility for automotive PCB assembly.
