Memory IC Procurement Notes

Verify the specific suffix 'INTR' confirms the industrial temperature grade and tape-and-reel packaging format against official datasheets. Confirm RoHS compliance status and humidity sensitivity classification prior to assembly. Ensure ordering quantities align with factory reel specifications to avoid partial reel handling issues during procurement.

Memory IC Selection Notes

Select this component when a 64 Mbit density with a 16-bit interface width is required for high-speed data buffering. The 200 MHz capability suits applications needing moderate bandwidth without excessive power consumption. The TSOP-II form factor facilitates integration into space-constrained designs where through-hole mounting is unsuitable.

Memory IC Part Context

This part belongs to the AS4C4M16D1A series of DDR SDRAM devices from Alliance Memory. The series offers various speed grades and organizational options. The 'A' designation typically indicates an enhanced version of the base architecture. This specific model focuses on industrial reliability and standard surface-mount compatibility.

Memory IC Replacement Considerations

Check for pin-compatible alternatives such as the AS4C4M16D1A-5TCN if commercial temperature grading suffices. Verify electrical parameter equivalence before substituting with parts from other manufacturers like ISSI or Winbond.
