The SST26VF064B-104I/SM is a 64-Mbit serial quad I/O (SQI™) flash memory device from Microchip (formerly SST), designed for embedded systems requiring high-speed, low-power data storage. It supports both SQI (6-line, 4-bit I/O) and SPI (Serial Peripheral Interface) protocols, enabling flexible integration into space-constrained designs.

Key Features

• High performance: Operates at a maximum clock frequency of 104 MHz (2.7–3.6V) or 80 MHz (2.3–3.6V), delivering fast read/write speeds.
• Low voltage operation: Functions with a single supply voltage range of 2.3–3.6V, ideal for battery-powered or low-power systems.
• Compact 8-pin SOIJ package: Measures 5.28 mm in body size, saving PCB space while maintaining high performance.
• Temperature range: Rated for -40°C to +85°C, ensuring reliability in industrial and automotive environments.
• SPI/SQI compatibility: Supports SPI mode (x1/x2/x4) and SQI’s 4-bit I/O for enhanced throughput.
• SuperFlash® technology: Uses proprietary CMOS-based architecture for low power consumption, fast erase/program cycles, and high endurance.
• Protection features: Includes write-protect (#WP) and hold (#HOLD) pins for data integrity.

Common uses include embedded systems, industrial control devices, IoT modules, consumer electronics, and automotive applications requiring non-volatile memory. Its low power, high speed, and compact size make it suitable for microcontroller-based designs, sensor nodes, and data logging systems.

Summary

The SST26VF064B-104I/SM combines high-speed SQI/SPI interfaces, low-power operation, and industrial-grade reliability, making it a versatile solution for memory-intensive applications. Its compatibility with multiple protocols and small footprint enable efficient system design across diverse embedded and IoT markets.
