The SST26WF080B/040B applies SuperFlash technology to provide the fastest erase times compared to competing products. Sector and block erase commands complete in just 18 ms, while full chip erase operations complete in 35 ms. In comparison, competing products require 5-15 seconds to perform full chip erase operations, making the SST26WF080B/040B approximately 300 times faster. This shortened erase time minimizes the time required for testing and firmware updates, increasing product production throughput and allowing customers to achieve significant cost savings.

The SQI interface is a high-speed 104 MHz quad I/O serial interface that enables increased data throughput with a minimal pin-count package. Through the low-latency XIP (execute-in-place) function, this interface allows programs to be stored and executed directly in flash memory without code shadowing in RAM devices. The SST26WF080B/040B delivers faster data throughput compared to equivalent x16 parallel flash devices without the high cost and numerous pins required for parallel flash. Additionally, the SQI interface is fully backward compatible with the existing Serial Peripheral Interface (SPI) protocol command set.

The SST26WF080B/040B is designed for low power operation to maximize battery life in portable power applications. Standby current consumption is rated at 10 µA, and in deep power-down mode, current consumption drops to a rated 1.8 µA. Active read current consumption at 104 MHz is rated at 15 mA. Operating at 1.8V, the SST26WF080B/040B combines low-power and compact form factor packaging characteristics, making it ideal for mobile devices, Bluetooth® headsets, GPS, camera modules, hearing aids, and various other battery-powered applications.

The SST26WF080B/040B offers excellent quality and reliability with data retention exceeding 100 years and more than 100,000 erase/write cycles, demonstrating outstanding durability. For flexible data/code protection, individual block software write protection and a 2 KB Secure ID area OTP (One-Time Programmable) function have been added. These features prevent unauthorized access and block malicious read, program, and erase attempts. Additionally, this product includes a JEDEC-compliant SFDP (Serial Flash Discoverable Parameter) table containing unique information about the SST26WF080B/040B's performance and operation to simplify software design.

Randy Drwinga, Vice President of Microchip's Memory Products Business Unit, stated, "By adding the SST26WF080B/040B SuperFlash products to Microchip's low-power 1.8V Serial Quad I/O product line, we are able to provide an excellent solution with the industry's fastest erase times for high-speed flash memory. These new products with compact form factor and low-power capability are ideal for next-generation embedded designs using portable batteries, including Internet of Things applications."
