Product details

What this PROM is and where it fits

The AMD AM27S37A/BUA is a 8Kbit (1K x 8) parallel PROM in a 32-pin ceramic LCC package. It is a non-volatile, one-time-programmable memory — the data pattern is set at the factory, no field updates. The 40 ns access time keeps bus timing tight for legacy processor or glue-logic interfaces. Rated across the full military temperature range of -55°C to 125°C, this part is suited for avionics, satellite, or downhole applications where the board sees extreme thermal cycling.

Lifecycle and sourcing reality

Package and mounting

32-pin ceramic LCC, surface mount. The hermetic package suits high-reliability environments where moisture ingress is a concern. Solder profile follows standard JEDEC for ceramic leadless carriers; no special reflow prep needed beyond a dry-bake if the parts have been in long-term storage.

Frequently asked questions

Will AM27S37A/BUA drop into a board designed for AM27S37/BUA?

Yes — same 1K x 8 organization, same 4.5 V supply, same 32-pin CLCC footprint. The AM27S37A/BUA is 5 ns faster (40 ns vs 45 ns), so it is a direct electrical and mechanical substitute.
