WS57C256F-55L Integrated Circuit by STMicroelectronics

The WS57C256F-55L is a high-performance, 32,768-word by 8-bit static random-access memory (SRAM) integrated circuit produced by the renowned manufacturer STMicroelectronics. This IC is designed to offer fast access times with a 55ns access time, making it an excellent choice for applications requiring high-speed data retrieval and storage.

Constructed with CMOS technology, the WS57C256F-55L is known for its low power consumption, which makes it ideal for use in battery-powered devices and other power-sensitive applications. The low standby current further enhances its suitability for portable electronics where power efficiency is a critical factor.

This SRAM chip features a wide operating temperature range, ensuring reliable performance across various environmental conditions. This makes it versatile for use in industrial, automotive, and consumer electronics that may be subjected to harsh temperatures.

The WS57C256F-55L is delivered in a 28-pin plastic leaded chip carrier (PLCC) package, which provides a compact footprint and robust physical protection for the silicon die inside. The PLCC package also allows for easy mounting on printed circuit boards and is suitable for surface mount technology (SMT), offering a secure and reliable connection to the rest of the electronic system.

Compatibility with common bus-oriented systems is facilitated by the device's tri-state output drivers, which allow for direct connection to the system bus without the need for additional buffering. This SRAM also supports full static operation, meaning that the information is retained as long as power is supplied, without the need for periodic refreshes.

Key features of the WS57C256F-55L include:

• High-speed access time: 55ns
• Low power CMOS technology
• Wide operating temperature range
• 28-pin PLCC packaging for SMT
• Tri-state output drivers for bus interfacing
• Full static operation – no refresh required

In summary, the WS57C256F-55L from STMicroelectronics is a reliable and efficient SRAM solution that offers fast data access, low power consumption, and a wide operating temperature range, all packaged in a convenient and durable PLCC form factor. Its ease of integration into various systems makes it a popular choice for designers and engineers looking to enhance their memory solutions.
