Product details
Overview
SST26VF032BAT-104I/MF from Microchip Technology is a 32-Mbit Serial Quad I/O™ (SQI™) Flash memory IC designed for high-speed, low-pin-count embedded storage. It operates at 104 MHz (2.7–3.6 V), supports x1/x2/x4 SPI and quad I/O protocols, features uniform 4-Kbyte sectors, and delivers 100,000 program/erase cycles with >100-year data retention in industrial temperature range (–40°C to +85°C).
For engineers reviewing the SST26VF032BAT-104I/MF datasheet, SST26VF032BAT-104I/MF pinout, SST26VF032BAT-104I/MF application, or SST26VF032BAT-104I/MF equivalent, key selection criteria include its dual-mode interface (SPI default / configurable SQI), hardware write-protection via WP# pin, flexible block protection architecture, and 8-contact WDFN (6 mm × 5 mm) package compatibility with space-constrained industrial controllers and automotive infotainment boot memory designs.
Technical Context
This device implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) enabling quad-data-rate transfers while maintaining full command-set compatibility with legacy SPI flash. Its SuperFlash® split-gate CMOS technology enables faster erase (18 ms sector, 35 ms chip) and lower active current (15 mA @ 104 MHz) versus conventional NOR flash.
The SST26VF032BAT-104I/MF defaults to SPI mode at power-up (WP#/HOLD# enabled, SIO2/SIO3 disabled), but supports reconfiguration to SQI mode via the Enable Quad I/O (EQIO) command. Its memory map comprises eight 8-Kbyte parameter blocks, two 32-Kbyte overlay blocks, sixty-two 64-Kbyte overlay blocks, and uniform 4-Kbyte sectors - all individually protectable via volatile and nonvolatile lock-down registers.

Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, industrial temperature grade (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low enable for command/data sequences; must remain low during full instruction execution |
| SIO0/SI | Serial Data I/O / Input | Default SPI input (SI) at power-up; becomes bidirectional SIO0 in SQI mode; latched on SCK rising edge |
| SIO1/SO | Serial Data I/O / Output | Default SPI output (SO) at power-up; becomes bidirectional SIO1 in SQI mode; driven on SCK falling edge |

| HOLD#/SIO3 | Hold Input / I/O | Pauses SPI communication without resetting clock sequence; disabled in SQI mode; repurposed as SIO3 in SQI mode |
| SCK | Serial Clock | Timing reference for all serial operations; rising edge latches inputs, falling edge shifts out outputs |
| VDD | Power Supply | 2.3 V–3.6 V main supply; powers core logic and I/O buffers |
| VSS | Ground | Reference ground for all internal circuitry and I/O signaling |
Key Features
| Feature | Design Value |
|---|---|

| Flexible Block Protection | Independent software lock-down of 8-Kbyte, 32-Kbyte, and 64-Kbyte blocks via volatile LBPR and nonvolatile nVWLDR registers |
| Write-Suspend Capability | Allows interruption of active program/erase to service higher-priority reads - critical for real-time firmware updates |
| Security ID with OTP Lock | Factory-unique 64-bit ID + 2-Kbyte user area; LSID command permanently prevents further writes - meets secure boot root-of-trust requirements |
| Low-Power Active Operation | 15 mA typical read current @ 104 MHz enables energy-efficient high-speed access in battery-backed or thermally constrained systems |

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 W25Q32JVSSIQ | 32 Mbit, 133 MHz max, standard SPI-only (no SQI), 8-lead SOIC package only | Lacks quad I/O mode and flexible overlay block structure; no Security ID or nVWLDR | Select when SQI bandwidth is unnecessary and SOIC footprint is required; verify WP#/HOLD# timing compatibility |
| Cypress S25FL132K0XMFI010 | 32 Mbit, 108 MHz max, supports both SPI and QPI modes, 8-WSON package, no OTP Security ID | QPI mode requires different command set; lacks factory-programmed unique ID and user-programmable SecID area | Choose for QPI-based legacy Cypress platforms; confirm absence of Security ID does not impact secure boot architecture |
Compared with W25Q32JVSSIQ and S25FL132K0XMFI010, the SST26VF032BAT-104I/MF uniquely combines SQI protocol flexibility, OTP Security ID with factory-unique binding, and nonvolatile block lock-down - making it optimal for new designs requiring scalable bandwidth, secure identity, and long-term firmware integrity assurance.

FAQ
What interface protocols does the SST26VF032BAT-104I/MF support?
The SST26VF032BAT-104I/MF supports both traditional SPI (x1/x2/x4 modes, Mode 0 and Mode 3) and Serial Quad I/O™ (SQI) protocols. At power-up, it defaults to SPI mode with WP# and HOLD# enabled; SQI mode is activated by setting the IOC bit and issuing the EQIO command. This dual-mode capability allows backward compatibility with existing SPI designs while enabling 4× bandwidth scaling in new architectures using the SST26VF032BAT-104I/MF.
How does the SST26VF032BAT-104I/MF implement hardware write protection?
The SST26VF032BAT-104I/MF uses the WP# pin in conjunction with the nonvolatile WPEN bit and IOC bit in its Configuration register. When IOC = 0 and WPEN = 1, asserting WP# low disables writes to the Block Protection and Configuration registers. The factory default sets WPEN = 0, so WP# is disabled at power-up unless explicitly enabled. This design prevents accidental writes during power transitions while allowing controlled activation of hardware protection in the SST26VF032BAT-104I/MF.
What is the purpose of the Security ID feature in the SST26VF032BAT-104I/MF?
The SST26VF032BAT-104I/MF includes a 2-Kbyte Security ID (SecID) with a factory-programmed 64-bit unique identifier and a user-programmable area. The SecID supports secure boot binding, device authentication, and firmware version tracking. Once locked via the LSID command, the entire SecID space becomes permanently read-only - ensuring immutable identity for the SST26VF032BAT-104I/MF throughout its operational life in regulated applications like automotive and medical systems.
Can the SST26VF032BAT-104I/MF suspend ongoing program or erase operations?
Yes, the SST26VF032BAT-104I/MF supports write-suspend functionality via the WRSU command. This allows an active program or erase operation to be paused, enabling immediate access to other memory regions for high-priority reads - essential in real-time systems. Suspension status is reported in the STATUS register (WSP/WSE bits), and resumed using WRRE. This capability ensures deterministic response times without compromising the integrity of the SST26VF032BAT-104I/MF's firmware update process.
What package and temperature grade does the SST26VF032BAT-104I/MF use?
The SST26VF032BAT-104I/MF is packaged in an 8-contact WDFN (6 mm × 5 mm) with exposed pad, rated for industrial temperature range (–40°C to +85°C). This compact, thermally efficient package supports high-density PCB layouts in space-constrained applications such as automotive control modules and portable medical devices - and is the exact form factor specified for the SST26VF032BAT-104I/MF in Microchip's official documentation.
