MX29SL800CTTI-90G

Memory IC Overview

The MX29SL800CTTI-90G is an 8-Mbit single-voltage NOR flash memory manufactured by Macronix. It operates on a 1.65V to 2.2V power supply and supports switchable 1,048,576 x 8 or 524,288 x 16 configurations. The device features a top boot sector architecture with a specific sector structure including 16K-byte, 8K-byte, 32K-byte, and 64K-byte sectors. It provides a maximum access time of 90ns and utilizes a 48-pin TSOP package.

Memory IC Feature Summary

• Supports hardware sector protection and chip unprotect functions to prevent accidental program or erase operations.
• Features erase suspend and resume capabilities allowing data reading from non-erased sectors during erase cycles.
• Includes a Ready/Busy output pin for hardware detection of program and erase completion.
• Compatible with the Common Flash Interface (CFI) standard for retrieving device characteristics.

Memory IC Applications

• Code storage in embedded systems requiring top boot sector architecture
• Firmware storage for microcontrollers operating at low voltage
• Data logging applications utilizing sector protection features

Memory IC Procurement Notes

Verify that the component matches the 48-pin TSOP physical package dimensions. Confirm the suffix indicates Top Boot Sector configuration as specified by the 'T' designation. Ensure the voltage requirements align with the 1.65V to 2.2V operational range before integration into the circuit design.

Memory IC Selection Notes

Select this component when a single 1.8V supply is available for read, erase, and program operations. Choose this model if the application requires a top boot sector layout for critical code storage. Verify compatibility with the required 90ns access speed and 48-pin surface mount packaging constraints.

Memory IC Part Context

This part belongs to the MX29SL series of single-voltage flash memories. It shares software and pinout compatibility with other single-voltage flash devices from Macronix. The device is designed for applications requiring high reliability and low power consumption in portable electronic devices.

Memory IC Replacement Considerations

Check for exact pinout and sector architecture match. Verify voltage compatibility. Consider alternative parts within the MX29SL family with identical boot sector configurations and package types.
