The AS7C1025B-12TJCNTR is a 512K x 8 synchronous SRAM manufactured by Alliance Memory. It features a high-speed, synchronous 25MHz x 8-bit pipeline architecture, providing random-access to the entire 512K x 8 memory array. It has a 12-ns access time and is capable of operating in both 5V and 3V supply systems. The AS7C1025B-12TJCNTR is available in 54-pin TSOP package, and features three-state outputs, a power-down mode and BLAST (Backward Loadable Address Sensed Test) feature, which allows the contents of the memory array to be tested in production. It offers current-limited output drivers and supports multiplexed address and data inputs, allowing higher density interface at a lower pin count. It is RoHS compliant and is offered in temperature range of 0 to 70°C.
