Product details

What this part is and where it fits

The AMD AM93L422/BUA is a 1Kbit parallel SRAM organized as 256 x 4 bits, with a 75 ns access time and a 4.5 V supply rail. It comes in a 28-pin ceramic CLCC package rated for the full military temperature range of -55 to 125 °C. This is a volatile memory device—data is lost at power-off—intended for high-reliability applications where a small, fast scratchpad or register file is needed, such as avionics, satellite, or downhole instrumentation. The ceramic hermetic package survives sealed environments and aggressive thermal cycling.

Lifecycle and sourcing

The AM93L422/BUA carries an active lifecycle status, meaning AMD continues to manufacture it. There is no last-time-buy or EOL notice.

Frequently asked questions

Will the AM93L422/BUA drop into a panel specified around the AM27S07A/BFA?

No. The AM93L422/BUA is 1Kbit (256 x 4) and the AM27S07A/BFA is 64 bits (16 x 4). The pinouts are not compatible, and the access times differ (75 ns vs 30 ns). Rewiring and a board layout change are required.
