SST39LF010-45-4C-WHE

Memory IC Overview

The SST39LF010-45-4C-WHE is a 1 Mbit (128K x 8) NOR flash memory manufactured by Microchip Technology using SuperFlash technology. It operates on a single 3.0V to 3.6V power supply and features a 45 ns access time. The device supports asynchronous parallel interfaces with latched address and data lines, conforming to JEDEC standard pinouts for x8 memories.

Memory IC Feature Summary

• Utilizes split-gate cell design and thick-oxide tunneling injector for enhanced reliability and manufacturability compared to alternative approaches.
• Provides uniform 4 KByte sector erase capability alongside fast byte-program operations with automatic write timing and internal Vpp generation.
• Includes hardware and software data protection schemes to prevent inadvertent writes during power-up or power-down sequences.

Memory IC Applications

• System applications requiring economical updating of program, configuration, or data memory.
• Storage solutions needing convenient and reliable non-volatile code execution.
• Embedded systems utilizing SuperFlash technology for fixed erase and program times independent of cycle count.

Memory IC Procurement Notes

Verify the specific ordering suffix 'WHE' against official documentation to confirm package type and temperature range compatibility. Confirm RoHS compliance status and moisture sensitivity levels prior to integration into surface mount assembly processes.

Memory IC Selection Notes

Select this component for designs requiring 1 Mbit capacity with 45 ns speed and 3.0V to 3.6V operation. Ensure system voltage constraints align with the specified commercial operating range of 0°C to +70°C.

Memory IC Part Context

This part belongs to the SST39LF series of Multi-Purpose Flash devices. It shares architectural similarities with the SST39LF020 and SST39LF040 variants, differing primarily in storage density while maintaining compatible command sets and interface protocols.
