Product details
Overview
SST26VF020A-80E/MF from Microchip Technology is a 2-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, and uniform 4-Kbyte sector/32-Kbyte & 64-Kbyte block erase architecture. It serves as nonvolatile program/data storage in microcontroller boot loaders, firmware update buffers, and industrial HMI displays.
For engineers reviewing the SST26VF020A-80E/MF datasheet, SST26VF020A-80E/MF pinout, SST26VF020A-80E/MF application, or SST26VF020A-80E/MF equivalent, key selection criteria include SQI/x4 SPI protocol support, 100,000-program/erase endurance, OTP Security ID capability, write-suspend functionality, and AEC-Q100 qualification for automotive use cases.
Technical Context
The SST26VF020A-80E/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. Its SuperFlash® split-gate CMOS technology delivers 20 ms typical sector erase and 256-byte page programming with software polling via BUSY bit.
It supports both SPI Mode 0 and Mode 3, configurable I/O pin mapping (via IOC bit), hardware/software reset, and flexible protection schemes including volatile lock-down (LDPS), BP0/BP1 block protection bits, and factory-programmed 128-bit unique ID within a 2-Kbyte OTP Security ID space.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2 Mbit (256 Kbytes), organized as uniform 4-Kbyte sectors for granular firmware partitioning |
| Interface Protocol | Serial Quad I/O™ (SQI) and backward-compatible SPI x1/x2/x4 - enables high-speed code execution directly from flash (XIP) |
| Max Clock Frequency | 80 MHz (2.3V–3.6V, Extended temp: –40°C to +125°C) - sustains 320 MB/s effective read bandwidth in x4 mode |
| Erase Performance | 20 ms typical sector erase (4 Kbyte); 40 ms typical chip erase - reduces firmware update latency in field-deployed systems |
| Endurance & Retention | 100,000 program/erase cycles minimum; >100 years data retention - suitable for long-lifecycle industrial controllers |
| Security Feature | One-Time-Programmable 2-Kbyte Security ID with 128-bit factory-unique identifier - enables secure device authentication and anti-cloning |
| Power Supply | Single 2.3V–3.6V supply - eliminates need for level shifters in 2.5V/3.3V host systems |
Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout command sequence - enables multi-device daisy-chaining on shared bus |
| SIO[3:0] | Serial I/O (Quad) | Multiplexed bidirectional data/command/address lines in SQI mode; default SI/SO in SPI mode - reduces PCB trace count vs. parallel flash |
| SCK | Serial Clock | Edge-triggered timing reference; rising edge latches input, falling edge shifts out output - supports Mode 0/Mode 3 clock polarity compatibility |
| WP# | Write-Protect Input | Hardware-enables BPL lock-down of STATUS register when WPEN=1 and IOC=0 - prevents accidental firmware corruption during power transitions |
| HOLD# | Communication Pause | Halts active SPI transaction without resetting internal state; only functional in SPI x1/x2 modes - allows host CPU to service higher-priority interrupts |
| RESET# | Hardware Reset | Resets internal logic and forces return to SPI mode; requires RSTHLD=1 in Configuration register - provides fail-safe recovery path independent of software stack |
| VDD / VSS | Power / Ground | 2.3V–3.6V supply with 15 µA typical standby current - enables ultra-low-power sleep states in battery-backed applications |
Key Features
| Feature | Design Value |
|---|---|
| Write-Suspend Capability | Interrupt ongoing program/erase to access another sector/block - enables real-time logging while updating firmware partitions |
| Flexible Erase Granularity | Uniform 4-Kbyte sectors + 32-Kbyte & 64-Kbyte overlay blocks - optimizes wear leveling and OTA update efficiency |
| OTP Security ID | Factory-programmed 128-bit unique ID + user-programmable 2-Kbyte area - supports cryptographic key binding and secure boot chain validation |
| Low-Power Active Read | 15 mA typical @ 80 MHz - minimizes thermal load in enclosed industrial enclosures |
| AEC-Q100 Qualified | Qualified for automotive Grade 2 (–40°C to +105°C) and Grade 3 (–40°C to +125°C) - validated for engine control, ADAS sensor modules, and infotainment head units |

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 W25Q20EW | 2-Mbit density, 133 MHz max SPI clock, no SQI interface, lacks OTP Security ID | Supports faster SPI reads but cannot achieve SQI-level bandwidth or hardware-based device identity | Select when cost-sensitive designs require maximum SPI speed without security or quad-I/O features |
| Cypress S25FL032P | 32-Mbit density, 80 MHz max, supports HyperBus but not SQI; includes 128-bit unique ID but no user-programmable OTP area | Higher capacity for complex firmware, but larger footprint and no write-suspend capability | Select when scaling to larger code images is required and SQI bandwidth is not critical |
Compared with W25Q20EW and S25FL032P, the SST26VF020A-80E/MF uniquely combines AEC-Q100 qualification, SQI/x4 throughput, write-suspend, and user-programmable OTP Security ID in a compact 6×5 mm WDFN package - making it optimal for safety-critical, space-constrained, and secure-boot applications.

FAQ
What is the operating temperature range for the SST26VF020A-80E/MF?
The SST26VF020A-80E/MF is rated for Extended temperature operation from –40°C to +125°C, meeting AEC-Q100 Grade 3 requirements. This makes it suitable for under-hood automotive applications and high-ambient industrial environments where thermal stability is critical. The 80 MHz maximum clock frequency is guaranteed across this full range when powered at 2.3V–3.6V.
Does the SST26VF020A-80E/MF support both SPI and SQI protocols simultaneously?
No - the SST26VF020A-80E/MF operates in either SPI mode (default after power-on reset) or SQI mode, selected via the Enable Quad I/O (EQIO) command. In SPI mode, pins function as SI/SO/WP#/HOLD#; in SQI mode, they become SIO[3:0]/SIO2/SIO3. The IOC bit in the Configuration register controls this mapping, and mode switching requires explicit command sequencing.
How does the Security ID feature work in the SST26VF020A-80E/MF?
The SST26VF020A-80E/MF includes a 2-Kbyte OTP Security ID space: 128 bits are factory-programmed with a unique identifier and cannot be altered, while the remaining area is user-programmable. The PSID command writes to the user area, and LSID permanently locks the entire space. Once locked (SEC bit = 1), no further writes are possible - ensuring immutable device identity for secure boot and anti-counterfeiting.
Can the SST26VF020A-80E/MF perform background operations using Write-Suspend?
Yes - the SST26VF020A-80E/MF supports Write-Suspend (WRSU command) to pause an active program or erase operation, allowing immediate access to another memory region. After servicing the urgent request, WRRE resumes the suspended operation. This is confirmed in the datasheet (DS20006279A, Section 4.0) and enables real-time system responsiveness without data loss or timeout failures.
What package options are available for the SST26VF020A-80E/MF?
The SST26VF020A-80E/MF is offered in two RoHS-compliant packages: 8-contact WDFN (6 mm × 5 mm) and 8-lead SOIC (3.90 mm). The -MF suffix in the part number explicitly denotes the WDFN variant. Pin assignments are identical between packages, enabling drop-in replacement in layout-constrained designs where footprint size drives component selection.
