Device identity and memory organization
The UPD431000AGZ-70LL-KJH-E3-A: The UPD431000AGZ-70LL-KJH--A is a 5V 1M-bit SRAM organized as 128K words by 8 bits. This is a parallel-interface static RAM, meaning it holds data without refresh as long as supply is present — suited for cache, buffer, or scratchpad memory in embedded systems where a simple memory interface is preferred over DRAM.
Supplied in Bulk packaging — loose units, not tape-and-reel. This matters for the pick-and-place line: Bulk means the parts arrive in tubes or trays, so the feeder setup differs from a reel-fed component. Confirm the handling method with your CM before the line runs.
