Product details
Overview
SST26VF064BEUI-104I/MF from Microchip Technology is a 64 Mbit Serial Quad I/O™ (SQI™) flash memory IC with factory-programmed EUI-48™ and EUI-64™ identifiers, 104 MHz max clock frequency (2.7–3.6 V), uniform 4 KByte sectors, and 100,000 program/erase endurance. It serves as non-volatile code/data storage in microcontroller boot systems requiring secure, high-speed serial interface and industrial temperature operation (–40°C to +85°C).
For engineers reviewing the SST26VF064BEUI-104I/MF datasheet, SST26VF064BEUI-104I/MF pinout, SST26VF064BEUI-104I/MF application, or SST26VF064BEUI-104I/MF equivalent, key selection criteria include SQI/x4 SPI protocol support, EUI-48/EUI-64 read-only access via SFDP, write-suspend capability, OTP Security ID space, and dual-package availability (WDFN-8 and SOIJ-8).
Technical Context
The SST26VF064BEUI-104I/MF implements a six-wire, 4-bit multiplexed I/O interface supporting both legacy SPI (Mode 0/3, x1/x2/x4) and high-throughput SQI protocols - enabling up to 4× data bandwidth at same clock frequency versus standard SPI. Its SuperFlash® split-gate cell architecture delivers faster erase (sector: 18 ms typ) and lower active current (15 mA @ 104 MHz) than conventional NOR flash.
It features dual protection layers: volatile Block-Protection Register (BPR) with lock-down (LBPR), and non-volatile Write-Lock Lock-Down Register (nVWLDR) for permanent block protection; plus hardware WP# and HOLD# pins active in SPI mode only. The device powers up in SPI mode with WP#/HOLD# enabled and SIO2/SIO3 disabled.
Key Specifications

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 W25Q64JVSIQ | 64 Mbit SPI-only (no SQI), 133 MHz max, no factory EUI, no OTP Security ID | Lacks EUI-48/EUI-64 and SQI interface - unsuitable for secure identity-critical or high-bandwidth designs | Select when cost-sensitive SPI-only systems require maximum clock speed and do not need embedded identifiers or quad I/O |
| Cypress S25FL164K0XMFI001 | 64 Mbit, 108 MHz, supports Octal DTR mode, includes SFDP v1.6, no factory EUI or OTP Security ID | Higher pin count (16-pin SOIC), lacks factory-programmed identifiers - requires external identity management | Select for designs needing octal interface scalability or Cypress ecosystem compatibility, where external identity handling is acceptable |
Compared with W25Q64JVSIQ and S25FL164K0XMFI001, the SST26VF064BEUI-104I/MF uniquely integrates factory EUI-48/EUI-64 and OTP Security ID in a compact 8-pin package with SQI support - delivering secure, space-constrained, high-throughput storage unattainable with alternatives.

FAQ
What interface protocols does the SST26VF064BEUI-104I/MF support?
The SST26VF064BEUI-104I/MF supports both Serial Peripheral Interface (SPI) in x1/x2/x4 modes (Mode 0 and Mode 3) and Serial Quad I/O™ (SQI™) protocol. It powers up in SPI mode with WP#/HOLD# enabled and requires the EQIO command and IOC bit setting to activate SQI mode. This dual-mode capability ensures backward compatibility while enabling 4× throughput in SQI mode.
Does the SST26VF064BEUI-104I/MF include factory-programmed identifiers?
Yes, the SST26VF064BEUI-104I/MF is factory-programmed with globally unique EUI-48™ and EUI-64™ identifiers stored in the Serial Flash Discoverable Parameters (SFDP) table. These identifiers are read-only and accessible via the SFDP read instruction (5AH), enabling secure device authentication and network identity assignment without requiring external EEPROM or programming steps.
What is the purpose of the OTP Security ID in the SST26VF064BEUI-104I/MF?
The SST26VF064BEUI-104I/MF includes a 2 KByte OTP Security ID area comprising a factory-programmed 64-bit unique identifier and a user-programmable segment. It supports PSID (Program Security ID) and LSID (Lockout Security ID) commands. Once locked via LSID, the entire Security ID space becomes permanently read-only - enabling cryptographic key binding, anti-cloning, and secure feature activation in production systems.
How does write-suspend functionality work in the SST26VF064BEUI-104I/MF?
The SST26VF064BEUI-104I/MF supports write-suspend for both Program and Erase operations. Issuing the WRSU (B0H) command pauses an active operation, allowing immediate access to other memory regions for reads or background tasks. Resume is triggered with WRRE (30H). This capability is essential for real-time systems where firmware updates must not block time-critical interrupt servicing or UI responsiveness.
What package options are available for the SST26VF064BEUI-104I/MF?
The SST26VF064BEUI-104I/MF is offered in two RoHS-compliant packages: 8-contact WDFN (6 mm × 5 mm) and 8-lead SOIJ (5.28 mm). Both share identical pinout and electrical characteristics per Microchip DS20006138A. The WDFN variant provides superior thermal performance and board-space efficiency, while the SOIJ offers legacy compatibility and ease of prototyping with through-hole or surface-mount assembly.
