M29W800DT70N1

Memory IC Overview

The M29W800DT70N1 is an 8-Mbit (1 Mbit x 8 or 512 Kbits x 16) non-volatile NOR flash memory manufactured by Micron Technology Inc. It operates on a single 2.7 V to 3.6 V supply voltage and features a 70 ns access time. The device utilizes a parallel interface with asynchronous timing and is housed in a TSOP48 package measuring 12 x 20 mm. It supports top boot block configuration, includes embedded program/erase controllers, and provides block protection capabilities.

Memory IC Feature Summary

• Asynchronous parallel interface for direct microprocessor connection
• Embedded program/erase controller for simplified command execution
• Independent block protection against accidental programming or erasing
• Erase suspend and resume modes allowing read/write operations during erase

Memory IC Applications

• Microprocessor initialization code storage
• Parameter data storage
• Application code storage
• Industrial control systems
• Consumer electronics firmware

Memory IC Procurement Notes

Verify the specific ordering suffix 'T70N1' against official manufacturer documentation to confirm the exact speed grade, package type, and temperature range. Confirm current production status as legacy components may be discontinued. Ensure compatibility with system voltage requirements of 2.7 V to 3.6 V. Check for RoHS compliance status if required by your manufacturing standards.

Memory IC Selection Notes

Select this component when a small boot block is required at the top of the memory map. Verify that the 70 ns access time meets the system clock requirements. Ensure the design accommodates the TSOP48 footprint. Consider the 8-Mbit density for applications requiring moderate code storage with independent block protection features.

Memory IC Part Context

This part belongs to the M29W800D family of 8-Mbit NOR flash memories. The 'DT' suffix indicates a top boot block configuration, while 'DB' denotes bottom boot block. The '70' specifies the 70 ns access speed. The 'N1' typically refers to the TSOP48 package variant. This family is designed for applications needing reliable code storage with flexible block protection.

Memory IC Replacement Considerations

Check for M29W800DB70N1 if bottom boot block configuration is acceptable. Verify pinout and electrical specifications match before substitution. Consult manufacturer obsolescence notices for potential end-of-life status.
