MBM29F400TC-55PFTN-E1

Memory IC Overview

The MBM29F400TC-55PFTN-E1 is a 4 Mbit (512K x 8 / 256K x 16) CMOS Flash memory manufactured by Fujitsu Semiconductor. It operates on a single 5.0 V supply for read, program, and erase functions, eliminating the need for external 12.0 V generation. The device features a maximum access time of 55 ns and supports sector erase architecture with boot code options. It utilizes embedded algorithms for automatic pre-programming and verification, ensuring reliable data integrity during write operations.

Memory IC Feature Summary

• Single 5.0 V operation minimizes system power requirements without requiring high voltage supplies.
• Sector erase architecture allows concurrent erasure of any combination of sectors or full chip erase.
• Embedded Erase and Program algorithms automatically handle pre-programming and data verification.
• Data Polling and Toggle Bit features provide hardware detection for program or erase cycle completion.

Memory IC Applications

• In-system programming for firmware storage in embedded controllers
• Boot code storage in top or bottom sector configurations
• Data logging applications requiring frequent sector updates
• Industrial control systems utilizing standard JEDEC command sets

Memory IC Procurement Notes

Verify the specific suffix PFTN corresponds to the Normal Bend Type TSOP package as documented in official Fujitsu datasheets. Confirm that the TC designation indicates the Top Sector boot configuration. Ensure compatibility with the required 5.0 V supply voltage and check for RoHS compliance status relative to the manufacturing date. Cross-reference the part number against current distributor listings to confirm availability and authenticity.

Memory IC Selection Notes

Select this component when a 4 Mbit capacity with 55 ns speed is required for single-voltage applications. The choice between TC (Top Sector) and BC (Bottom Sector) depends on the specific boot code location requirements of the target system architecture. Consider the 48-pin TSOP package constraints for PCB layout. Verify that the host system supports the standard JEDEC software commands compatible with E2 PROMs for seamless integration.

Memory IC Part Context

This part belongs to the MBM29F400 series of 4 Mbit Flash memories from Fujitsu. It shares architectural similarities with other devices in the family, such as the MBM29F400BC, differing primarily in sector protection settings and package variants. The series is designed for high-reliability applications requiring robust erase/program cycles and low power consumption during standby modes.

Memory IC Replacement Considerations

Direct substitutes include the MBM29F400BC-55PFTN-E1 if bottom sector booting is acceptable. Other compatible parts within the same specification sheet may include variants with different package suffixes like PD for PLCC, provided pinout compatibility is verified. Always consult the latest continuity of specifications documents from Fujitsu or Spansion for updated part numbering.
