Memory IC Procurement Notes

Verify the specific suffix 'SIN' confirms the 28-SOP package and industrial temperature grade. Confirm current availability status as supply constraints may affect lead times. Ensure the design accommodates the 2.5 V to 3.6 V operating voltage range. Check for any end-of-life notifications or recommended replacements from the manufacturer.

Memory IC Selection Notes

Select this part when low power and industrial temperature stability are required. Compare against standard voltage SRAMs if system power is strictly 5 V. Consider package size constraints as the 28-SOP footprint must fit the PCB layout. Verify interface compatibility with the host microcontroller's address and data lines.

Memory IC Part Context

This component belongs to the AS62V256A series of low-power SRAMs from Alliance Memory. It shares architectural similarities with other members of the family but differs in package type and voltage specifications. The series targets applications requiring non-volatile-like retention with volatile speed characteristics in compact form factors.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the same voltage range. Verify that substitute parts maintain the 70 ns access time and industrial temperature rating. Ensure the replacement offers equivalent low-power characteristics to meet system efficiency requirements.
