AT49BV640S-70CU

Memory IC Overview

The AT49BV640S-70CU is a 64 Mbit NOR Flash memory integrated circuit manufactured by Microchip Technology. It features an asynchronous parallel interface with a maximum access time of 70 ns. The device is housed in a 64-pin CBGA package measuring 9x10 mm. It supports standard voltage operation and provides non-volatile data storage suitable for code execution applications.

Memory IC Feature Summary

• Supports direct code execution from flash memory
• Provides high-speed asynchronous parallel data access
• Retains stored data without continuous power supply

Memory IC Applications

• Embedded system firmware storage
• Industrial control unit program memory
• Consumer electronics boot code retention

Memory IC Procurement Notes

Verify the specific package variant and suffix against official Microchip documentation to ensure compatibility with existing board layouts. Confirm current production status as legacy components may have limited availability or end-of-life designations. Cross-reference manufacturer part numbers with distributor listings to avoid counterfeit sources.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity with 70 ns speed is required for parallel interface designs. Ensure the host system supports the CBGA form factor and associated thermal management requirements. Validate that the operating voltage range aligns with the target application's power supply specifications before integration.

Memory IC Part Context

This part belongs to the AT49BV series of NOR Flash memories, designed for general-purpose non-volatile storage. The series typically offers flexibility in organization and interface speeds. The AT49BV640S-70CU specifically addresses needs for moderate-density code storage in embedded environments requiring fast random access capabilities.

Memory IC Replacement Considerations

Check for AT49BV640D-70CU if a different CBGA footprint is acceptable. Verify electrical compatibility with other variants in the AT49BV family before substitution.
