This document describes the features and characteristics of the A67L83161/A67L83181/ A67L73321/A67L73361 Series 256K X 16/18, 128K X 32/36 LVTTL, flow-through DBATM SRAM.
This document describes the A67L83161, A67L83181, A67L73321, and A67L73361 series of synchronous SRAMs from AMIC Technology. These devices utilize Direct Bus Alternation (DBA) technology to achieve 100% bus utilization during read-write alternations without wait cycles. The chips are available in 256K x 16/18 and 128K x 32/36 configurations with access times ranging from 10ns to 12ns.
| Access Time | 10/11/12 ns |
