SST39SF040-70-4C-PHE

Memory IC Overview

The SST39SF040-70-4C-PHE is a 4-Mbit (512K x 8) Multi-Purpose Flash manufactured using SuperFlash technology. It operates on a single 4.5V to 5.5V supply and features a 70 ns access time. The device utilizes a parallel interface with TTL-compatible I/Os and includes internal VPP generation for write operations. It supports uniform 4-Kbyte sector erasure, byte programming, and hardware/software data protection schemes.

Memory IC Feature Summary

SuperFlash Technology: Split-gate cell design ensures superior reliability and manufacturability compared to alternate approaches.
Sector Erase Capability: Uniform 4-Kbyte sectors allow for efficient memory management and updates.
Data Protection: Includes hardware noise/glitch protection and JEDEC-approved software data protection sequences.
Internal VPP Generation: Eliminates the need for external high-voltage supplies during program and erase cycles.

Memory IC Applications

Code storage in embedded systems requiring direct execution from flash.
Configuration memory for hardware devices needing frequent updates.
Data storage applications requiring non-volatile retention of user settings.

Memory IC Procurement Notes

Verify the package type matches the 'PHE' suffix designation against official Microchip documentation. Confirm the temperature range corresponds to the 'C' commercial rating. Ensure compatibility with the required voltage levels and timing specifications for the target system design.

Memory IC Selection Notes

Select this component for applications requiring 4-Mbit capacity with a 70 ns access speed. It is suitable for systems operating within the 4.5V to 5.5V range. Consider the PLCC or PDIP package options based on board space and assembly requirements. Verify that the 4-Kbyte sector size aligns with the application's erase granularity needs.
