Product Description

Infineon CY62148ELL-55SXI static RAM (SRAM) is a high-performance asynchronous memory device with a total memory size of 4MB (512K words by 8 bits). It offers a maximum random access time of 45ns, enabling rapid read and write operations suitable for embedded systems requiring quick volatile data storage.

This SRAM chip is built with a surface mount SOIC package featuring 32 pins and dimensions of 20.75mm length, 11.43mm width, and 2.81mm height. The device supports an operational voltage range from 4.5V minimum up to 5.5V maximum with a supply current draw of 20mA, providing compatibility with a variety of system power requirements.

Designed for robust industrial use, the CY62148ELL-55SXI performs reliably across a wide operating temperature range of -40°C to 85°C. Its asynchronous timing type simplifies integration by reducing timing constraints in system design.

This makes it ideal for buffering in microcontroller-based applications, temporary data logging in industrial equipment, and firmware shadow RAM in legacy electronic systems. The surface mount SOIC form factor supports modern PCB assembly methods, ensuring efficient and reliable mounting and soldering on printed circuit boards.

The asynchronous operation provides flexible memory access without the need for clock synchronization. Fast access time and adequate clock frequency assist in responsive memory cycles in embedded designs. Wide voltage operating range supports compatibility with both standard and higher-voltage systems.

Industrial temperature capability ensures deployment in harsh environments and demanding applications. The compact SOIC package suits surface-mount assembly processes widely used in electronics manufacturing. Applications include use in embedded control units requiring 8-bit parallel data transfer and temporary data buffering.
