SST38VF6401B-70I/CD

Memory IC Overview

The SST38VF6401B-70I/CD is a 64 Mbit (4M x 16) Advanced Multi-Purpose Flash Plus device manufactured using CMOS SuperFlash technology. It operates on a single 2.7V to 3.6V power supply and supports asynchronous parallel interfaces with 70 ns access times. The component features hardware boot block protection, user-controlled individual block protection, password security, and a 128-bit unique ID. It includes a hardware reset pin, erase-suspend capabilities, and write-buffer programming for efficient data updates.

Memory IC Feature Summary

• Advanced MPF+ architecture utilizing split-gate cell design for superior reliability and manufacturability
• Integrated hardware and software data protection schemes including boot block and individual block locking
• Fast page read capability enabling rapid sequential data retrieval within an eight-word buffer
• Supports multiple end-of-write detection methods such as toggle bits, data polling, and ready/busy output

Memory IC Applications

• System code storage requiring frequent firmware updates
• Configuration memory in embedded controllers
• Data logging applications needing high endurance
• Secure storage for unique identifiers and security keys

Memory IC Procurement Notes

Verify the specific package type against the datasheet, as the suffix indicates a TSOP-48 variant. Confirm that the 'I' designation aligns with the required industrial temperature range specifications for your application environment. Ensure compatibility with existing JEDEC standard pin assignments before finalizing procurement.

Memory IC Selection Notes

Select this component when a 16-bit interface is required for system bus compatibility. Consider the 70 ns access speed for systems operating at moderate clock frequencies. Evaluate the need for hardware boot block protection if secure code execution from power-up is critical. Verify that the 2.7V to 3.6V voltage range matches the target system's power supply rails.

Memory IC Part Context

This part belongs to the SST38VF640B series of 64 Mbit NOR flash memories. It shares core SuperFlash technology and command sets with other variants in the family, differing primarily in organization, speed grades, and package options. The series is designed to replace older generation flash devices while offering improved performance and lower power consumption.

Memory IC Replacement Considerations

Direct replacements include SST38VF6402B, SST38VF6403B, and SST38VF6404B models from the same manufacturer. These alternatives share identical electrical characteristics and pinouts but may differ in boot block configuration or package availability. Cross-reference the specific suffix codes to ensure mechanical fit and thermal requirements are met.
