Memory IC Procurement Notes

Verify the specific suffix ASE1 against official datasheets to confirm the TSOP44 package and pinout configuration. Ensure compatibility with system voltage levels between 1.8V and 3.6V. Confirm that the parallel interface requirements match the host controller's capabilities. Check for RoHS compliance status in current documentation.

Memory IC Selection Notes

Select this component when a 4 Mbit capacity with 16-bit parallel width is required. Consider the TSOP44 package constraints for PCB layout. Evaluate the 150ns write cycle time against application latency needs. Compare power consumption characteristics at 1.8V versus 3.6V operation if energy efficiency is critical.

Memory IC Part Context

This part belongs to the MB85R4M2T series of FRAM devices from RAMXEED. These chips are designed as replacements for traditional EEPROMs or Flash memories where endurance and speed are priorities. The series typically includes variants with different interfaces, such as SPI or parallel, and various package options like FBGA or TSOP.

Memory IC Replacement Considerations

Infineon Technologies FM25R4M-BHNTR is a comparable 4 Mbit FRAM with a parallel interface. Verify pin compatibility and timing parameters before substitution.
