W24257AS-35 32K X 8 High Speed CMOS Static RAM SMD IC

Description

W24257AS-35 32K X 8 High Speed CMOS Static RAM SMD IC The W24257AS -35 is a high-speed, low-power CMOS static random-access memory (SRAM) integrated circuit. It is organized as 32,768 words by 8 bits, providing a total storage capacity of 256 Kilobits. This device is manufactured using Winbond’s high-performance CMOS technology, which is the foundation of its speed and power characteristics. The chip operates on a single 5-volt power supply and is designed for fully static operation, meaning it requires no refresh cycles to retain data. Access to the memory is controlled through standard input signals: Address lines (A0-A14) select the memory location, while Chip Select (CS), Output Enable (OE), and Write Enable (WE) pins manage the read and write operations. Data is transferred via an 8-bit bidirectional bus (I/O1-I/O8). The outputs are three-stated, allowing for easy connection to a shared system bus. The device is directly TTL compatible, ensuring it can interface seamlessly with other common logic families in a system without needing level shifters. Features: High-Speed CMOS Technology.
