SST25VF080B-50-4I-S2AF-T

Memory IC Overview

The SST25VF080B-50-4I-S2AF-T is an 8 Mbit (1M x 8) SPI Flash memory IC manufactured by Microchip Technology. It operates within a supply voltage range of 2.7V to 3.6V and supports clock frequencies up to 50 MHz. The device utilizes the SuperFlash technology for non-volatile data storage, ensuring high endurance with a minimum of 100,000 write/erase cycles and a data retention period of at least 100 years. It is housed in an 8-SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports standard, dual output, dual I/O, quad output, and quad I/O SPI modes for flexible interface configurations.
• Features sector protection mechanisms including global block protect and individual sector protect bits.
• Incorporates hardware write protect functionality via the WP# pin to prevent accidental data modification.

Memory IC Applications

• Firmware storage for embedded microcontrollers
• Code execution in place (XIP) applications
• Data logging systems requiring reliable non-volatile storage

Memory IC Procurement Notes

Verify the suffix S2AF confirms the 8-SOIC package and tape-and-reel packaging format. Confirm the -4I suffix indicates the industrial temperature grade (-40°C to +85°C). Ensure compatibility with the host system's SPI controller regarding voltage levels and command set support. Check for RoHS3 compliance status if required by specific environmental regulations.

Memory IC Selection Notes

Select this component when an 8 Mbit capacity is required with industrial temperature stability. The 50 MHz speed rating suits applications needing moderate read performance. Compare against SST25VF016B if higher density is needed, or SST25VF040B for smaller footprint requirements. Ensure the host design accommodates the 8-SOIC package dimensions and power supply constraints.

Memory IC Part Context

This part belongs to the SST25VF series of SPI Flash memories from Microchip. It shares architectural similarities with other members like the SST25VF040B and SST25VF016B, differing primarily in density and package options. The SuperFlash technology provides enhanced reliability compared to traditional NOR flash architectures.

Memory IC Replacement Considerations

SST25VF080B-50-4I-S2AE offers the same electrical specifications but in tube packaging instead of tape-and-reel. SST25VF080B-50-4Q-S2AF provides identical performance in an 8-WSON package. Verify pinout compatibility before substituting different package types.
