Overview

The SST26VF032BA-104I/MF is a 32 Mbit Serial Quad I/O (SQI) flash memory device that utilizes a 4-bit multiplexed I/O interface to achieve high performance while maintaining a low pin count. Operating between 2.7V and 3.6V, it supports clock frequencies up to 104 MHz, enabling fast data throughput for embedded systems. This NOR flash is designed for applications requiring high reliability and fast boot times from a compact 8-lead WDFN package.

Why Choose This Part

The SuperFlash technology offers significantly faster erase times compared to conventional flash, with typical write cycle times of 1.5ms. Its SQI interface provides 400 Mbps burst data rates, rivaling parallel flash performance in a much smaller footprint. Additionally, the individual-block write protection and permanent lock-down capability offer robust security for critical system code.

Applications

Execute-in-Place (XiP) Boot Code
High-speed SQI interface allows microcontrollers to execute code directly from external flash, reducing the need for large internal SRAM.
Industrial Data Logging
Provides reliable non-volatile storage for sensor logs and system events across an industrial temperature range of -40 to +85 degrees Celsius.
Firmware Storage
Stores main application firmware for embedded devices with hardware-based block protection to prevent accidental overwrites.
Secure Identity Storage
Utilizes the 2-KByte OTP Secure ID and factory-preprogrammed 64-bit unique identifier for device authentication and serial numbering.

Getting Started

To interface with this device, configure your MCU SPI peripheral for Mode 0 or 3 and use the SQI enhancement for maximum throughput. Microchip provides the MPLAB Harmony framework which includes drivers for SST26 series flash, or you can use standard SPI libraries by polling the BUSY bit in the STATUS register. Ensure the WP# and HOLD# pins are correctly biased or disabled via software to prevent unintended write protection during development.
