Product details
Overview
SST26VF032BEUIT-104I/SM from Microchip Technology is a 32 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 read/write (2.3–3.6 V). It serves as nonvolatile program/data storage in embedded boot code, firmware update, and configuration retention applications.
For engineers reviewing the SST26VF032BEUIT-104I/SM datasheet, SST26VF032BEUIT-104I/SM pinout, SST26VF032BEUIT-104I/SM application, or SST26VF032BEUIT-104I/SM equivalent, key selection criteria include SQI/x4 SPI interface compatibility, industrial temperature range (−40°C to +85°C), AEC-Q100 qualification, EUI-48/EUI-64 accessibility via SFDP, and hardware write protection via WP#/HOLD# pins.
Technical Context
The SST26VF032BEUIT-104I/SM implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) compatible with both traditional SPI (x1/x2 modes) and high-speed SQI protocol, enabling up to 4× data throughput versus standard SPI at identical clock frequency. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling for enhanced endurance and retention.
It features configurable I/O mode via the IOC bit: default power-up state enables WP# and HOLD# for SPI operation; setting IOC=1 enables SIO2/SIO3 for Quad I/O. The device supports burst reads (linear and wrap-around), write-suspend, software reset, and flexible block protection including volatile lock-down (LBPR) and non-volatile write-lock lock-down (nVWLDR).

FAQ
What is the operating voltage range for the SST26VF032BEUIT-104I/SM?
The SST26VF032BEUIT-104I/SM operates from 2.3 V to 3.6 V with full functionality. At 2.7–3.6 V, it achieves 104 MHz maximum clock speed; at 2.3–3.6 V, max speed is 80 MHz. This dual-voltage capability allows seamless integration with both legacy 3.3 V and modern low-power 2.5 V systems while maintaining guaranteed performance specs across the entire range.
Does the SST26VF032BEUIT-104I/SM support both SPI and SQI protocols?
Yes, the SST26VF032BEUIT-104I/SM supports backward-compatible SPI (x1/x2 modes) and high-speed SQI (x4 mode). After power-on reset, it defaults to SPI mode with SI/SO pins active. Enabling SQI requires issuing the EQIO command and setting the IOC bit to '1', which reassigns SIO2/SIO3 for quad I/O operation - verified in DS20006152A, Section 4.5.8.
How is the factory-programmed EUI-48/EUI-64 identifier accessed on the SST26VF032BEUIT-104I/SM?
The EUI-48 and EUI-64 identifiers are pre-programmed into the Serial Flash Discoverable Parameters (SFDP) table and accessed using the SFDP read instruction (5AH command). Their exact byte offsets are documented in DS20006152A, page 72. These identifiers are read-only, globally unique, and used for network stack initialization and device authentication in automotive and IoT applications.
What package type does the SST26VF032BEUIT-104I/SM use?
The SST26VF032BEUIT-104I/SM uses an 8-lead SOIJ (Small Outline Integrated Circuit, J-bend) package measuring 5.28 mm in width. This RoHS-compliant, surface-mount package supports automated assembly and provides mechanical robustness for automotive and industrial environments - confirmed in DS20006152A, Figure 2-1 and Table 2-1.
Is the SST26VF032BEUIT-104I/SM qualified for automotive applications?
Yes, the SST26VF032BEUIT-104I/SM is AEC-Q100 qualified for automotive applications and rated for the industrial temperature range (−40°C to +85°C). This qualification covers stress testing for temperature cycling, humidity, and electrical robustness - explicitly stated in the "Features" section of DS20006152A, page 1.
