Product details
Overview
SST26VF020A-104I/MF from Microchip Technology is a 2-Mbit Serial Quad I/O™ (SQI™) Flash memory IC supporting dual-voltage operation (2.3V–3.6V), 104 MHz SPI/SQI read speed, uniform 4-Kbyte sectors, and OTP 2-Kbyte Security ID. It serves as nonvolatile program/data storage in microcontroller boot loaders, firmware update buffers, and industrial HMI displays.
For engineers reviewing the SST26VF020A-104I/MF datasheet, SST26VF020A-104I/MF pinout, SST26VF020A-104I/MF application, or SST26VF020A-104I/MF equivalent, key selection considerations include quad-I/O burst performance, write-suspend capability for real-time interrupt handling, hardware/software write protection granularity, and AEC-Q100 qualification for automotive control modules.
Technical Context
The SST26VF020A-104I/MF implements SuperFlash® split-gate CMOS technology with thick-oxide tunneling injector, enabling 100,000 program/erase cycles and >100-year data retention. Its six-wire SQI interface supports Mode 0/3 clocking and multiplexed SIO[3:0] for x4 data throughput at 104 MHz.
It integrates dual-protocol support: default SPI x1/x2 mode after power-on reset, configurable to SQI mode via EQIO command. The device features a software STATUS register (BUSY/WEL/BP0/BP1/BPL), Configuration register (IOC/VLP/WPEN/RSTHLD), and dedicated security infrastructure including factory-programmed 128-bit ID and user-programmable 2-Kbyte Sec ID space.

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 SPI-only (no SQI), 133 MHz max, 1.65V–1.95V/2.7V–3.6V dual supply | Lacks quad I/O burst and write-suspend; requires separate voltage rail for low-VDD operation | Choose when SQI bandwidth is unnecessary and ultra-low-voltage operation is required. |
| Cypress S25FL032P | 32-Mbit density, 104 MHz, supports XIP and DDR modes, no OTP Security ID | Higher capacity but no factory-unique ID; lacks AEC-Q100 qualification | Choose for larger firmware images where security ID and automotive qualification are not mandatory. |

FAQ
What voltage ranges does the SST26VF020A-104I/MF support for reliable read/write operation?
The SST26VF020A-104I/MF supports two voltage ranges: 2.7V–3.6V for maximum 104 MHz operation in industrial temperature range, and 2.3V–3.6V for 80 MHz operation across both industrial (–40°C to +85°C) and extended (–40°C to +125°C) temperature grades. All program and erase functions operate within these single-supply ranges without auxiliary voltages.
How does the SST26VF020A-104I/MF implement write protection, and what layers are available?
The SST26VF020A-104I/MF provides three complementary write protection layers: (1) software-configurable block protection (BP0/BP1 bits) with lock-down (BPL), (2) hardware WP# pin enabled via WPEN/IOC bits, and (3) volatile lock-down (VLP bit) activated by LDPS command. These can be combined to protect boot sectors while allowing runtime updates to application partitions.
Does the SST26VF020A-104I/MF support true quad-I/O mode, and how is it enabled?
Yes, the SST26VF020A-104I/MF supports true quad-I/O mode using SIO[3:0] pins for simultaneous command/address/data transfer. It is enabled by issuing the EQIO (38H) command after setting the IOC bit in the Configuration register. The device defaults to SPI mode at power-up for backward compatibility.
What is the purpose and structure of the Security ID feature in the SST26VF020A-104I/MF?
The SST26VF020A-104I/MF includes a 2-Kbyte Security ID space comprising a factory-programmed 128-bit unique identifier (read-only) and a user-programmable area. It is accessed via PSID/RSID/LSID commands and locked permanently with LSID to prevent tampering - enabling secure boot, device authentication, and regulatory traceability.
Can the SST26VF020A-104I/MF suspend an ongoing erase or program operation, and how is this used?
Yes, the SST26VF020A-104I/MF supports write-suspend via WRSU (B0H) command, allowing interruption of active program or erase operations to service urgent reads or commands. This is essential in real-time systems where deterministic latency is required - e.g., responding to safety interrupts during firmware update without data corruption.
