CY7C4235-15JC

FIFOs Memory Overview

The CY7C4235-15JC is a synchronous FIFO memory IC manufactured by Cypress Semiconductor Corp. It features a storage capacity of 2K x 18 bits, providing a total density of 36 kilobits. The device supports a maximum data rate of 66.7MHz with a typical access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V and consumes a maximum supply current of 35mA. The component is housed in a 68-pin PLCC package (24.23x24.23mm) and is designed for surface mount installation. It functions as a unidirectional buffer suitable for digital signal processing applications.

FIFOs Memory Feature Summary

• Synchronous clocked read and write interfaces for reliable data buffering
• High-speed operation supporting up to 66.7MHz data rates
• Low-power CMOS technology for efficient energy consumption
• Programmable flags indicating full and empty status conditions

FIFOs Memory Applications

• Digital signal processing systems requiring temporary data storage
• Interface bridging between components operating at different clock speeds
• Data acquisition systems needing buffer memory for incoming streams

FIFOs Memory Procurement Notes

Verify the specific suffix '15JC' against official Infineon or Cypress documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status as older batches may be non-compliant. Ensure the 68-PLCC package dimensions match the target PCB footprint. Check for obsolescence status as Cypress memory products are often discontinued or superseded by newer families.

FIFOs Memory Selection Notes

Select this component when a 2K x 18 bit synchronous FIFO is required. Compare access times and power consumption against alternative devices if system constraints are tight. Verify that the 4.5V to 5.5V supply range aligns with the system voltage rails. Consider package availability and lead times given the potential end-of-life status of legacy Cypress parts.

FIFOs Memory Part Context

This part belongs to the CY7C42xx series of high-speed synchronous FIFOs from Cypress Semiconductor. These devices were widely used in embedded systems before the company's acquisition by Infineon Technologies. The series offers various capacities and widths, with the CY7C4235 specifically providing 18-bit word width for wider data bus applications.

FIFOs Memory Replacement Considerations

Check for direct replacements such as the CY7C4241 or CY7C4256 series which offer similar functionality but potentially different capacities or packages. Consult Infineon's current product portfolio for modern equivalents that maintain pin compatibility or require adapter solutions.
