SST25VF080B

Overview

The SST25VF080B is an 8 Mbit (1 MB) serial NOR flash memory device designed for high-performance applications requiring low power consumption and small physical footprints. It utilizes the Serial Peripheral Interface (SPI) and supports clock frequencies up to 50 MHz, with specialized modes like Auto Address Increment (AAI) to speed up programming times. Operating on a 2.7V to 3.6V supply, it features a standby current of only 5 uA, making it ideal for battery-operated systems.

Why Choose This Part

This device features the Auto Address Increment (AAI) programming mode, which significantly reduces total programming time compared to standard byte-programming methods. It also includes hardware and software write protection mechanisms, such as WP# and HOLD# pins, to ensure data integrity in noisy environments.

Applications

Getting Started

To interface with this device, configure your microcontroller SPI peripheral for Mode 0 or Mode 3 with a maximum clock speed of 50 MHz. Engineers should utilize the AAI word-program instruction to optimize throughput during bulk data writes. Hardware write protection can be managed via the WP# pin, while the HOLD# pin allows pausing serial communication without deselecting the device.
