S29AS008J70BFA040

Memory IC Overview

The S29AS008J70BFA040 is an 8Mbit parallel NOR flash memory device from the Spansion AS-J series. It features a 1M x 8 or 512K x 16 memory organization and operates with a fast access time of 70 ns. The component utilizes CMOS technology and supports 3.0V-only supply voltage for read operations. It is housed in a 48-FBGA package measuring 8.15x6.15 mm, designed for surface mount applications requiring non-volatile data storage.

Memory IC Feature Summary

• Supports 3.0V-only read access for simplified power management
• Fast 70 ns access time for high-speed data retrieval
• Flexible memory organization compatible with 8-bit or 16-bit interfaces

Memory IC Applications

• Code execution in embedded systems
• Storage of firmware and boot code
• Data retention in consumer electronics

Memory IC Procurement Notes

Verify the specific suffix BFA040 to confirm the 48-FBGA package type and pinout configuration. Ensure compatibility with 3.0V logic levels in the target circuit design. Confirm that the source document explicitly lists this part number as active and available for procurement before placing orders.

Memory IC Selection Notes

Select this component when a small capacity NOR flash with fast access times is required for code execution. The 3.0V operation makes it suitable for low-power applications. Consider the FBGA package size constraints during PCB layout planning to ensure adequate clearance and thermal management.

Memory IC Part Context

This part belongs to the Spansion AS-J series of parallel NOR flash memories. The series is characterized by its boot sector architecture and support for standard parallel interfaces. It serves as a direct replacement for older generations of 8Mbit NOR flashes in legacy designs requiring similar performance characteristics.

Memory IC Replacement Considerations

Check datasheets for equivalent parts from Microchip or Infineon with matching 8Mbit capacity and 70ns speed. Verify package compatibility and pin assignments before substitution. Ensure voltage requirements align with the existing system design.
