64-bit SRAM in a ceramic flat pack — what it is and where it fits
The AMD AM27S07A/BFA is a 64-bit volatile parallel SRAM organized as 16 words of 4 bits each. It delivers a 30 ns access time from a single 4.5 V supply, and is packaged in a 16-pin ceramic flat pack rated for the full military temperature range of -55°C to 125°C. This combination of hermetic ceramic package, wide temperature range, and fast access time targets high-reliability applications such as avionics, satellite payloads, missile guidance electronics, and downhole instrumentation where commercial or industrial-grade parts won't survive the environment.
30 ns access time — bus timing fit
The 30 ns access time is the timing parameter for this SRAM. It determines how fast the memory presents data after the address is stable on the parallel bus.
