MBM29F080-90PFTN

Memory IC Overview

The MBM29F080-90PFTN is a 1-megabit (1M x 8) CMOS Flash memory manufactured by Fujitsu. It operates with a single 5.0 V supply for read, program, and erase functions, eliminating the need for external high-voltage generation. The device features a maximum access time of 90 ns and utilizes a TSOP-32 plastic package. It supports asynchronous operation and includes sector erase architecture with bottom boot block configuration.

Memory IC Feature Summary

• Single 5.0 V power supply requirement for all operations
• Sector erase architecture supporting concurrent sector erasure
• Embedded algorithms for automatic programming and verification
• Data polling and toggle bit status detection mechanisms

Memory IC Applications

• System firmware storage in embedded controllers
• Boot code storage for microprocessor systems
• Data storage in industrial control applications
• Configuration memory for network equipment

Memory IC Procurement Notes

Verify the exact suffix against official Fujitsu documentation to confirm pin compatibility and bend type specifications. Ensure the component meets required environmental operating temperatures and voltage tolerances for the target application. Cross-reference the manufacturer part number with current datasheets to validate availability and revision status before procurement.

Memory IC Selection Notes

Select this component when a 1 Mbit capacity with 90 ns access speed is required. It is suitable for designs needing a single 5 V supply without external voltage translators. Consider the TSOP-32 package constraints for PCB layout. Verify that the bottom boot block architecture aligns with the system's boot sequence requirements.

Memory IC Part Context

This part belongs to the MBM29F series of 5 V-only Flash memories from Fujitsu Semiconductor. The series typically offers capacities ranging from 256 Kbit to 4 Mbit. These devices are designed for in-system programming and replace traditional EPROMs in many applications due to their lower power consumption and higher reliability.

Memory IC Replacement Considerations

Check for direct substitutes within the MBM29F series with compatible pinouts and electrical characteristics. Verify if newer generations from Fujitsu or other manufacturers offer equivalent performance with improved endurance or packaging options.
