M29W640GT70ZA6EP

Memory IC Overview

The M29W640GT70ZA6EP is a 64-Mbit Parallel NOR Flash memory component manufactured by Micron Technology. It operates on a single 3V supply voltage with a range of 2.7V to 3.6V for program, erase, and read operations. The device features an asynchronous random access time of 70ns and utilizes a TFBGA-48 surface-mount package. It supports x16 data bus width and includes embedded algorithms for byte/word programming.

Memory IC Feature Summary

• Supports asynchronous random and page read operations for flexible data access
• Includes embedded program/erase controller with suspend and resume capabilities
• Features hardware block protection via dedicated Vpp/WP pin

Memory IC Applications

• Code storage for boot applications
• Application code execution
• Operating system storage
• In-place execution (XIP) environments

Memory IC Procurement Notes

Verify the exact suffix 'ZA6EP' against official Micron documentation, as standard listings often show 'ZA6F'. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as availability may vary. Ensure the specific package variant matches your PCB footprint requirements before finalizing orders.

Memory IC Selection Notes

Select this component when a 64-Mbit density with 70ns speed is required in a compact TFBGA-48 package. It is suitable for designs needing parallel interface flexibility and hardware write protection. Consider alternative speeds like 60ns if higher performance is needed, or different packages if TFBGA is not feasible.

Memory IC Part Context

This part belongs to the M29W series of 3V NOR Flash memories. It shares architectural similarities with other M29W devices but offers specific density and packaging options. The series is designed for reliable code storage in consumer, industrial, and computing applications requiring non-volatile memory solutions.

Memory IC Replacement Considerations

Check for direct substitutes within the M29W640 family, such as M29W640GT70NA6E or M29W640GL70NB6F, ensuring package compatibility (TSOP vs TFBGA). Verify that pinouts and command sets are identical to avoid redesign efforts.
