Product details
Overview
SST26VF064BEUIT-104I/SM from Microchip Technology is a 64 Mbit Serial Quad I/O™ (SQI™) flash memory IC with factory-programmed EUI-48/EUI-64 identifiers, 104 MHz max clock frequency (2.7–3.6 V), 4 KByte uniform sector erase, and industrial temperature range (–40°C to +85°C). It serves as non-volatile program/data storage in microcontroller boot loaders, firmware update buffers, and secure device identity modules.
For engineers reviewing the SST26VF064BEUIT-104I/SM datasheet, SST26VF064BEUIT-104I/SM pinout, SST26VF064BEUIT-104I/SM application, or SST26VF064BEUIT-104I/SM equivalent, key selection criteria include SQI/x4 SPI interface compatibility, EUI-48/EUI-64 read-only identifier access via SFDP, write-suspend capability for real-time interrupt handling, 256-byte page programming, and hardware/software block protection with OTP lock-down.
Technical Context
This device implements a six-wire, 4-bit multiplexed I/O interface supporting both legacy SPI (x1/x2) and high-speed SQI (x4) protocols with Mode 0 and Mode 3 clock polarity compatibility. Its SuperFlash® split-gate cell architecture enables 100,000 program/erase cycles and >100-year data retention.
It integrates dual protection layers: volatile Block-Protection Register (BPR) with global unlock command, and non-volatile Write-Lock Lock-Down Register (nVWLDR) with one-time programmable bits per 8/32/64 KByte block. The Security ID space includes 64-bit factory-unique OTP segment and 2 KByte user-programmable area locked via LSID command.

FAQ
What is the primary interface protocol supported by SST26VF064BEUIT-104I/SM?
SST26VF064BEUIT-104I/SM supports both Serial Peripheral Interface (SPI) in x1/x2 modes and Serial Quad I/O™ (SQI™) in x4 mode. At power-up, it defaults to SPI mode for backward compatibility. The EQIO command enables SQI mode, which uses SIO[3:0] for multiplexed bidirectional data transfer, quadrupling throughput at the same clock frequency compared to standard SPI. SST26VF064BEUIT-104I/SM operates in Mode 0 and Mode 3 clock polarity configurations.
Does SST26VF064BEUIT-104I/SM include factory-programmed unique identifiers?
Yes, SST26VF064BEUIT-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). Additionally, SST26VF064BEUIT-104I/SM features a 2 KByte Security ID space containing a 64-bit factory-preprogrammed unique segment and a user-programmable area locked via the LSID command.
How does SST26VF064BEUIT-104I/SM implement memory protection?
SST26VF064BEUIT-104I/SM provides three-tiered memory protection: (1) software-controlled Block-Protection Register (BPR) with per-block write/read lock bits, (2) volatile Lock-Down Block-Protection Register (LBPR) disabling BPR writes until power cycle, and (3) non-volatile Write-Lock Lock-Down Register (nVWLDR) with one-time programmable bits permanently fixing protection states. Hardware WP# pin support is enabled only in SPI mode when IOC=0 and WPEN=1, protecting only BPR and Configuration registers.
What erase and program capabilities does SST26VF064BEUIT-104I/SM offer?
SST26VF064BEUIT-104I/SM supports uniform 4 KByte sector erase, configurable 8/32/64 KByte block erase, and full chip erase. Typical erase times are 18 ms (sector/block) and 35 ms (chip). Programming occurs in 256-byte pages in x1 or x4 mode. It supports write-suspend to pause active Program/Erase operations for urgent memory access, with status monitored via BUSY, WSP, and WSE bits in the Status register.
What package and environmental specifications apply to SST26VF064BEUIT-104I/SM?
SST26VF064BEUIT-104I/SM is offered in an 8-contact WDFN package (6 mm × 5 mm) and is RoHS-compliant. It is rated for industrial temperature operation from –40°C to +85°C and qualified to AEC-Q100 Grade 2 and Grade 3 standards for automotive applications. The device uses Microchip's proprietary SuperFlash® technology, delivering 100,000 program/erase cycles and greater than 100 years of data retention at 85°C.
