Memory IC datasheet and documents for SST25VF032B-80-4I-QAE

SST25VF032B-80-4I-QAE

Memory IC Overview

The SST25VF032B-80-4I-QAE is a 32 Mbit SPI Serial Flash memory manufactured using CMOS SuperFlash technology. It operates on a single voltage supply of 2.7V to 3.6V and supports clock frequencies up to 80 MHz. The device features uniform 4 KByte sectors, 32 KByte overlay blocks, and 64 KByte overlay blocks for flexible erasure. It includes an Auto Address Increment (AAI) word programming mode and hardware/software end-of-write detection. The component is available in 8-lead SOIC and 8-contact WSON packages.

Memory IC Feature Summary

Utilizes proprietary SuperFlash technology with split-gate cell design for enhanced reliability and lower power consumption during program and erase operations.
Supports high-speed serial communication via SPI compatible interface with Mode 0 and Mode 3 protocols, including a dedicated Hold pin to pause sequences without resetting the device.
Provides comprehensive write protection through software Block-Protection bits and a hardware Write Protect pin that locks down status register settings.

Memory IC Applications

Embedded systems requiring non-volatile code storage
Industrial control applications needing reliable data retention
Consumer electronics utilizing low-pin-count memory solutions

Memory IC Procurement Notes

This specific part number is classified as an End-of-Life (EOL) device by Microchip Technology. Verification of current availability requires direct contact with Microchip Sales or authorized distributors. Replacement information should be obtained from the manufacturer rather than relying on standard inventory checks.

Memory IC Selection Notes

Designers must account for the obsolete status of this component when selecting parts for new products. Verify package compatibility between SOIC and WSON variants if substituting within the family. Ensure system voltage requirements align with the 2.7V to 3.6V operating range specified in the datasheet.

Memory IC Part Context

The SST25VF032B belongs to the SST 25 series Serial Flash family produced by Microchip Technology. This series is characterized by its four-wire SPI interface and low pin-count packaging options. The device leverages SuperFlash technology to achieve superior endurance and data retention compared to alternative flash memory approaches.
