ALLIANCE MEMORY AS7C513B-12TCN SRAM, Asynchronous, 512 Kbit, 32K x 16bit, TSOP-II, 44 Pins, 4.5 V

AS7C513B-12TCN is a 5V 32K×16 CMOS SRAM. It is a high performance CMOS 524,288-bit static random access memory (SRAM) device organized as 32,768 words × 16 bits. It is designed for memory applications where fast data access, low power, and simple interfacing are desired. Equal address access and cycle times (tAA, tRC, tWC) of 10/12/15/20ns with output enable access times (tOE) of 5, 6, 7, 8ns are ideal for high performance applications. The chip enable input active-low CE permits easy memory expansion with multiple-bank memory systems. The device provides multiple center power and ground pins, and separate byte enable controls, allowing individual bytes to be written and read. Active-low LB controls the lower bits, I/O0 � I/O7, and active-low UB controls the higher bits, I/O8 � I/O15.
