Overview

The SST26VF032BA-104I/SM is a 32 Mbit Serial Quad I/O (SQI) Flash memory device that utilizes a 4-bit multiplexed I/O interface to boost performance while maintaining a low pin count. Operating on a 2.7V to 3.6V supply, it supports high-speed clock frequencies up to 104 MHz and features a 4M x 8 memory organization. This NOR Flash is designed for systems requiring fast boot times and efficient execute-in-place (XIP) capabilities in a compact 8-pin SOIJ package.

Why Choose This Part

This device features SuperFlash technology which provides significantly faster erase times and better reliability compared to standard Flash. The SQI interface provides up to 104 MHz performance, enabling high data transfer rates while the 15uA standby current makes it suitable for power-sensitive applications.

Applications

Execute-in-Place (XIP) Firmware
High-speed SQI throughput allows microcontrollers to execute code directly from the external Flash, reducing internal SRAM requirements.
Industrial Embedded Systems
Robust operation within a -40C to +85C temperature range for data logging and configuration storage in harsh environments.
Rapid Boot Storage
Ideal for storage of bootloader and OS kernel images where minimize start-up latency is critical for the user experience.

Getting Started

Interface the memory via a standard SPI or SQI bus on your MCU; ensure the WP# and HOLD# pins are correctly biased as they are disabled at power-up on this 'BA' variant. Microchip provides the MPLAB Harmony framework which includes drivers for the SST26 series, simplifying the implementation of filesystem or raw block access.
