SST26VF064BT-104V/MF

Memory IC Overview

The SST26VF064BT-104V/MF is a 64 Mbit Serial Quad I/O flash memory manufactured by Microchip Technology. It operates on a single voltage supply ranging from 2.3 V to 3.6 V and supports clock frequencies up to 80 MHz within this range. The device utilizes SuperFlash technology for high reliability and low power consumption, featuring an 8-contact WDFN package. It includes flexible erase capabilities with uniform 4-Kbyte sectors and overlay blocks, along with hardware and software write protection mechanisms.

Memory IC Feature Summary

• Supports both SPI and Serial Quad I/O protocols with multiplexed I/O pins
• Features proprietary SuperFlash technology for enhanced endurance and data retention
• Includes a factory-programmed 64-bit unique identifier and user-programmable security ID space
• Provides flexible block protection with permanent lock-down capability

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Industrial control applications operating in extended temperature ranges
• Automotive electronics compliant with AEC-Q100 standards
• Consumer devices utilizing low-pin-count packaging solutions

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pin configuration and default I/O states. Ensure the selected variant matches the required voltage range and interface mode for your system design. Cross-reference the datasheet revision to confirm current manufacturing status and any applicable product change notifications.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity is required with support for high-speed quad I/O operations. Consider the 80 MHz maximum frequency limit when designing for the 2.3 V to 3.6 V supply range. Evaluate the need for hardware write protection features and the specific package constraints of the 8-contact WDFN form factor during the initial schematic capture phase.

Memory IC Part Context

This part belongs to the SST26VF064B/SST26VF064BA family of Serial Quad I/O flash memories. The 'T' suffix typically indicates tape and reel packaging, while 'MF' denotes the 8-contact WDFN package type. The '104V' designation specifies the industrial plus temperature grade and voltage range compatibility. This series is designed to replace older SPI-only flash devices in space-constrained designs.

Memory IC Replacement Considerations

Direct replacements include other SST26VF064B variants with compatible pinouts and electrical characteristics. Verify that substitute parts support the same SQI protocol and voltage requirements. Check for any differences in default I/O configuration bits that may require firmware adjustments.
