Product details
Overview
SST26VF064B-104I/MN from Microchip Technology is a 64-Mbit Serial Quad I/O™ (SQI™) Flash memory IC operating at up to 104 MHz (2.7V–3.6V), organized in uniform 4-Kbyte sectors with flexible block protection, and designed for embedded boot code storage and firmware update in space-constrained industrial systems.
For engineers reviewing the SST26VF064B-104I/MN datasheet, SST26VF064B-104I/MN pinout, SST26VF064B-104I/MN application, or SST26VF064B-104I/MN equivalent, key selection considerations include SPI/SQI protocol support, 104 MHz read speed, 4-Kbyte sector erase granularity, hardware write protection via WP# pin, and industrial temperature range (-40°C to +85°C).
Technical Context
The SST26VF064B-104I/MN implements a six-wire, 4-bit multiplexed I/O interface supporting both legacy SPI (Mode 0/3, x1/x2/x4) and high-speed SQI protocols, enabling quadrupled data throughput at identical clock frequencies without additional pins. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling for enhanced endurance and retention.
At power-up, SST26VF064B-104I/MN defaults to SPI mode with WP# and HOLD# enabled (IOC = 0), distinguishing it from the SST26VF064BA variant. It supports software-controlled write suspend, burst reads (linear and wrap-around), and dual-mode status/configuration register access for real-time operation monitoring and configuration.

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 W25Q64JVSSIQ | 64 Mbit, 133 MHz max, standard SPI only (no SQI), no built-in Security ID | Lacks quad I/O acceleration and hardware-secured identity; suitable where cost is primary constraint | Select when SQI bandwidth is unnecessary and BOM cost sensitivity outweighs security and speed advantages |
| Cypress S25FL164K0XMFI001 | 64 Mbit, 85 MHz max, supports XIP but no OTP Security ID; different command set and status register layout | Requires firmware adaptation for command compatibility; no factory-unique identifier for device binding | Choose only if existing Cypress ecosystem integration exists and SQI performance is not required |
Compared with W25Q64JVSSIQ and S25FL164K0XMFI001, SST26VF064B-104I/MN delivers superior boot speed via SQI, built-in factory-unique Security ID for device authentication, and finer 4-Kbyte erase granularity-critical for field-upgradable embedded systems requiring security, longevity, and deterministic timing.

FAQ
What is the default I/O configuration mode for SST26VF064B-104I/MN at power-up?
The SST26VF064B-104I/MN powers up with IOC = 0, enabling WP# and HOLD# pins and disabling SIO2/SIO3 for SPI-compatible operation. This distinguishes it from the SST26VF064BA variant, which defaults to IOC = 1. The IOC bit can be modified via the Configuration register to switch to SQI mode.
Does SST26VF064B-104I/MN support both SPI and SQI protocols simultaneously?
No - SST26VF064B-104I/MN operates in either SPI mode (x1/x2/x4) or SQI mode, selected via the IOC bit. When IOC = 0, WP# and HOLD# are active and SIO2/SIO3 are disabled; when IOC = 1, those pins become SIO2/SIO3 and SQI commands (e.g., 6BH, EBH) become valid. Mode switching requires explicit configuration.
What is the significance of the "-104I/MN" suffix in SST26VF064B-104I/MN?
The "-104" denotes maximum clock frequency of 104 MHz under 2.7V–3.6V operation; "I" specifies Industrial temperature range (-40°C to +85°C); "/MN" indicates the 8-contact WDFN (6 mm × 5 mm) package. This exact suffix confirms the device meets all timing, thermal, and mechanical specifications defined in DS20005119K.
Can SST26VF064B-104I/MN perform erase operations while another memory region is being read?
Yes - SST26VF064B-104I/MN supports Write Suspend functionality. An active sector/block erase or page program can be suspended using the SUSPEND command, allowing immediate read access to other unprotected memory regions, then resumed with RESUME - essential for real-time systems with concurrent firmware and data access.
How is hardware write protection implemented on SST26VF064B-104I/MN?
SST26VF064B-104I/MN implements hardware write protection via the WP# pin, controlled by the nonvolatile WPEN bit in the Configuration register. When WPEN = 1 and WP# is driven low, writes to the Block Protection and Configuration registers are blocked. The factory default is WPEN = 0, so WP# is inactive until explicitly enabled in firmware.
