Product Overview

AS7C4098A-15JCN is a 5.0V 4Mb (256K 16) CMOS fast SRAM. It is a high-performance CMOS 4,194,304-bit static random access memory (SRAM) device organized as 262,144 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 5/6ns are ideal for high-performance applications. The chip enable input 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. LB controls the lower bits, I/O1I/O8, and UB controls the higher bits, I/O9I/O16. All chip inputs and outputs are TTL- and CMOS-compatible, and operation is for 5.0V supply.
