Product details
Overview
SST26VF064BEUI-104I/SM from Microchip Technology is a 64 Mbit Serial Quad I/O™ (SQI™) flash memory IC with factory-programmed EUI-48™ and EUI-64™ identifiers, supporting 104 MHz operation at 2.7–3.6 V, 4 KByte uniform sectors, and dual-voltage operation (2.3–3.6 V). It serves as nonvolatile code/data storage in microcontroller boot systems requiring secure, high-speed serial interface and industrial temperature support (–40°C to +85°C).
For engineers reviewing the SST26VF064BEUI-104I/SM datasheet, SST26VF064BEUI-104I/SM pinout, SST26VF064BEUI-104I/SM application, or SST26VF064BEUI-104I/SM equivalent, key selection criteria include SQI/x4 SPI protocol compatibility, EUI-48/EUI-64 read-only access via SFDP, write-suspend capability, OTP Security ID space, and WDFN-8 (6 mm × 5 mm) package with industrial-grade reliability.
Technical Context
The SST26VF064BEUI-104I/SM implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) supporting both Mode 0 and Mode 3 SPI timing, enabling quad-data-rate transfers without increasing pin count. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling for enhanced endurance and retention.
It features dual operational modes: default SPI mode (SI/SO pins active, WP#/HOLD# enabled) and configurable SQI mode (SIO[3:0] active, WP#/HOLD# disabled), selected via the IOC bit in the Configuration register. Memory protection includes volatile lock-down (LBPR), non-volatile write-lock lock-down (nVWLDR), and individual block protection with 8×8 KByte, 2×32 KByte, and 126×64 KByte erasable blocks.

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, standard SPI (no SQI), 133 MHz max, no factory EUI, no OTP Security ID | Lacks SQI bandwidth and embedded identity features; suitable only where quad interface and secure ID are not required | Select when cost sensitivity outweighs need for EUI-48/EUI-64, SQI speed, or OTP security space |
| Cypress S25FL164K0XMFI010 | 64 Mbit, HyperBus interface (not SPI/SQI compatible), 166 MHz, no EUI, no OTP Security ID | Requires HyperBus controller; incompatible pinout and command set; no direct replacement path | Choose only for new designs targeting Cypress PSoC or Traveo platforms with HyperBus support |

FAQ
What is the primary interface protocol supported by the SST26VF064BEUI-104I/SM?
The SST26VF064BEUI-104I/SM supports both Serial Quad I/O™ (SQI™) and backward-compatible SPI protocols, including x1/x2/x4 modes and Mode 0/Mode 3 timing. At power-up, it defaults to SPI mode with SI/SO pins active; SQI mode is enabled via the IOC bit and EQIO command. This dual-mode capability allows seamless integration into legacy SPI systems while enabling bandwidth scaling in new designs using the SST26VF064BEUI-104I/SM.
Does the SST26VF064BEUI-104I/SM include factory-programmed unique identifiers?
Yes, the SST26VF064BEUI-104I/SM 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 plug-and-play device identity without external MAC address storage - a key feature distinguishing the SST26VF064BEUI-104I/SM from generic SPI flash devices.
What package type and footprint does the SST26VF064BEUI-104I/SM use?
The SST26VF064BEUI-104I/SM is offered in an 8-contact WDFN package measuring 6 mm × 5 mm, with exposed pad for thermal performance. It is RoHS-compliant and rated for industrial temperature range (–40°C to +85°C). Pin assignments match standard 8-pin serial flash layouts, ensuring drop-in compatibility with existing PCB footprints designed for similar-density WDFN flash devices - a critical design advantage of the SST26VF064BEUI-104I/SM.
How does the SST26VF064BEUI-104I/SM implement memory protection?
The SST26VF064BEUI-104I/SM provides three-tiered protection: (1) software-configurable block protection via the Block-Protection Register (WBPR), (2) volatile lock-down (LBPR) preventing runtime changes, and (3) non-volatile write-lock lock-down (nVWLDR) permanently fixing protection bits. These mechanisms apply independently to 8/32/64 KByte blocks and support secure firmware partitioning - a robust implementation not found in baseline SPI flash, making the SST26VF064BEUI-104I/SM suitable for safety-critical applications.
What is the maximum clock frequency and operating voltage range for the SST26VF064BEUI-104I/SM?
The SST26VF064BEUI-104I/SM operates at up to 104 MHz when supplied with 2.7–3.6 V, and up to 80 MHz at 2.3–3.6 V. This dual-voltage capability allows reliable operation across wide input ranges common in automotive and industrial environments. The 104 MHz rating applies specifically to the SST26VF064BEUI-104I/SM variant - confirmed in DS20006138A, page 1 - and enables high-throughput code execution in resource-constrained embedded systems.
