• Provides non-volatile storage with high endurance cycles
• Operates within standard low voltage supply ranges

Memory IC Applications

• Embedded system firmware storage
• Microcontroller code execution space
• Data logging applications

Memory IC Procurement Notes

Verify the manufacturer designation carefully, as the part number appears in listings associated with both Renesas Electronics and Microchip Technology due to historical acquisitions. Confirm the specific datasheet version and package tolerance (SOIC-8) directly with the supplier to ensure compatibility with your design requirements before purchase.

Memory IC Selection Notes

Select this component when a 4-megabit capacity is required for serial flash storage. Ensure the host controller supports the SPI interface and can handle the 33 MHz maximum clock speed. Verify that the 8-SOIC package dimensions fit the available PCB footprint and that the operating voltage range matches the system power rails.

Memory IC Part Context

This component belongs to the serial flash memory category, often utilized in conjunction with microcontrollers for storing boot code or configuration data. While originally developed under Microchip Technology, distribution channels may list it under Renesas Electronics following corporate restructuring. It serves as a compact, cost-effective solution for small-scale data persistence needs.

Memory IC Replacement Considerations

Cross-reference with AT26F004-MU for alternative package options. Verify pinout compatibility and electrical specifications against other 4Mbit SPI flash devices from various manufacturers to ensure functional equivalence in the target application.
