Overview

The SST26WF040BT-104I/NP is a 4Mbit Serial Quad I/O (SQI) Flash memory device designed for low-power, high-performance applications. It operates on a 1.65V to 1.95V supply range and supports clock frequencies up to 104 MHz for high-bandwidth data throughput. The device utilizes a 4-bit multiplexed I/O interface to significantly improve performance over standard serial SPI devices while maintaining a small 8-USON footprint.

Why Choose This Part

The SQI interface provides high-throughput nibble-wide data transfer, achieving performance comparable to parallel Flash while using fewer pins. Its flexible erase architecture, featuring 4 KByte sectors and varying overlay blocks, allows for efficient memory management and frequent parameter updates. Additionally, the wide operating voltage down to 1.65V extends battery life in portable electronics.

Applications

Battery-Powered IoT Devices
Ideal for wearable and remote sensors requiring low-voltage operation and a deep power-down current of 1.8uA.
Execute-in-Place (XiP) Firmware
High-speed 104 MHz Quad I/O performance allows for direct code execution from Flash, reducing the need for large internal RAM.
Secure Data Logging
Utilizes individual block write protection and a 2 KByte OTP Security ID for protecting sensitive configuration data or calibration constants.

Getting Started

Integrate this memory using standard Mode 0 or Mode 3 SPI protocols, or transition to SQI mode via software commands for maximum 104 MHz throughput. Developers can use Microchip's MPLAB Harmony framework or standard SPI drivers to manage page-programming and sector erase operations. Ensure the host microcontroller supports 1.8V I/O logic levels to match the device supply requirements without level shifting.
