Memory IC Procurement Notes

Verify the specific suffix STIN confirms the TSOP II package and lead-free status against official datasheets. Confirm RoHS compliance requirements match project specifications. Ensure the 55 ns speed grade aligns with system timing constraints. Check for moisture sensitivity levels if reflow soldering is planned. Validate that the 128K x 8 organization fits the memory map design.

Memory IC Selection Notes

Select this part when a 1 Mbit capacity with 55 ns speed is required in a compact surface-mount package. Compare against other Alliance Memory SRAMs for pin compatibility and power needs. Consider the 2.7 V minimum voltage for low-power designs. Evaluate the TSOP II footprint against PCB space limitations. Verify industrial temperature rating suffices for the target application environment.

Memory IC Part Context

This component belongs to the AS6C1008 series of low-power CMOS SRAMs. It offers non-volatile-like retention without the complexity of flash programming. The series provides a drop-in replacement for many legacy SRAMs. It is widely used in embedded systems where fast read/write cycles are critical. The manufacturer ensures long-term availability for industrial applications.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the same speed grade. Verify voltage tolerance matches existing circuitry. Ensure package dimensions allow for physical substitution. Review updated datasheets for any functional changes in newer revisions.
