Product details
Overview
SST26VF032B-104V/MF from Microchip Technology is a 32-Mbit Serial Quad I/O™ (SQI™) Flash memory IC operating at up to 104 MHz (2.7–3.6 V), supporting x1/x2/x4 SPI and full SQI protocols, with 4-Kbyte uniform sectors, 100,000 write/erase cycles, and industrial temperature range (–40°C to +85°C). It serves as nonvolatile code/data storage in microcontroller boot systems, FPGA configuration, and embedded firmware updates.
For engineers reviewing the SST26VF032B-104V/MF datasheet, SST26VF032B-104V/MF pinout, SST26VF032B-104V/MF application, or SST26VF032B-104V/MF equivalent, key selection considerations include its dual-mode SPI/SQI interface, hardware write-protection via WP# pin, flexible block protection architecture, 2-Kbyte Security ID with OTP factory ID, and support for burst reads with wrap-around in 8/16/32/64-byte increments.
Technical Context
This device implements Microchip's SuperFlash® technology with split-gate cells and thick-oxide tunneling injectors, enabling faster erase (18 ms sector, 35 ms chip) and lower total energy per operation versus conventional Flash. Its six-wire SQI interface uses multiplexed SIO[3:0] pins for command/address/data transfer, quadrupling throughput over standard SPI at identical clock rates.
The SST26VF032B-104V/MF defaults at power-up to SPI mode with WP# and HOLD# enabled (IOC = 0), distinguishing it from the SST26VF032BA variant. It supports Mode 0 and Mode 3 clock polarity/idle states, includes a 16-bit STATUS register with BUSY/WEL/WPLD bits, and features volatile and nonvolatile lock-down mechanisms for block protection and Security ID.

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), no Security ID, different block protection granularity | Lacks quad I/O performance boost and hardware security features; suited for cost-sensitive, non-security-critical designs | Select when SQI bandwidth and OTP ID are unnecessary, and legacy SPI compatibility is prioritized |
| Cypress S25FL132K0XMFI001 | 32 Mbit, 108 MHz max, supports both SPI and QPI modes, includes 64-bit unique ID but no user-programmable Security ID space | Offers QPI instead of SQI; lacks flexible nVWLDR lock-down and parameter block read-lock capability | Choose for systems already using Cypress QPI ecosystem and requiring simpler protection model |
Compared with W25Q32JVSSIQ and S25FL132K0XMFI001, the SST26VF032B-104V/MF delivers superior security (OTP 64-bit ID + user-programmable 2-Kbyte SecID), finer-grained protection (per-block read/write lock-down), and higher effective throughput via true 4-bit SQI-making it optimal for safety- and security-aware embedded systems where firmware integrity and update agility are critical.

FAQ
What is the maximum operating frequency of the SST26VF032B-104V/MF and under what voltage conditions?
The SST26VF032B-104V/MF achieves a maximum clock frequency of 104 MHz when operated within the 2.7 V to 3.6 V supply range. At the wider 2.3 V to 3.6 V range, its maximum frequency is reduced to 80 MHz. This specification is confirmed in the official Microchip datasheet DS20005218J, and applies to both SPI and SQI read operations under industrial temperature conditions.
Does the SST26VF032B-104V/MF support Quad I/O mode out of the box, or does it require configuration?
The SST26VF032B-104V/MF powers up in SPI mode with WP# and HOLD# enabled (IOC = 0) and SIO2/SIO3 disabled. To activate Quad I/O mode, the host must first set the IOC bit in the Configuration register via the WRCR instruction, then issue the EQIO command. This behavior is explicitly defined in Section 4.5.8 of the SST26VF032B-104V/MF datasheet and distinguishes it from the SST26VF032BA variant.
How does the Security ID feature of the SST26VF032B-104V/MF work, and can it be modified after programming?
Each SST26VF032B-104V/MF contains a 2-Kbyte Security ID space: a factory-programmed 64-bit unique identifier (immutable) and a user-programmable area. The PSID command writes to the user area, and LSID permanently locks the entire space. Once LSID executes, neither factory nor user portions can be altered or erased-confirmed in Section 4.3 of the official datasheet DS20005218J.
What package type is used for the SST26VF032B-104V/MF, and are pin assignments consistent across variants?
The SST26VF032B-104V/MF uses an 8-contact WDFN package (6 mm × 5 mm), with pinout matching the SOIC and TBGA variants per Figure 2-1 in DS20005218J. Pin functions-including CE#, SIO[3:0], WP#, HOLD#, SCK, VDD, and VSS-are electrically and logically identical across packages; only mechanical dimensions and thermal characteristics differ.
Can the SST26VF032B-104V/MF be used in automotive applications, and what qualifications does it hold?
Yes-the SST26VF032B-104V/MF is qualified per AEC-Q100 Grade 1 (–40°C to +125°C), Grade 2 (–40°C to +105°C), and Grade 3 (–40°C to +85°C). Its industrial temperature rating (–40°C to +85°C) corresponds to Grade 3, making it suitable for cabin and body-control modules. Full qualification documentation is provided in Microchip's AEC-Q100 test reports referenced in DS20005218J.
