CY7C4205-15ASC

FIFOs Memory Overview

The CY7C4205-15ASC is a high-speed, low-power synchronous first-in first-out (FIFO) memory component manufactured by Cypress Semiconductor. It features an 18-bit data width and a depth of 256 locations, providing a total storage capacity of 4,608 bits. The device supports clocked read and write interfaces with independent enable pins for asynchronous operation. It operates at frequencies up to 100 MHz, characterized by a 10 ns read/write cycle time. The part is housed in a 68-pin PLCC package.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read and write operations
• Includes programmable Almost Full and Almost Empty status flags
• Features center power and ground pin configuration to reduce noise
• Provides width and depth expansion capabilities for system scalability

FIFOs Memory Applications

• High-speed data acquisition systems
• Multiprocessor interface buffering
• Communications data buffering

FIFOs Memory Procurement Notes

Verify the specific suffix 'ASC' against the manufacturer's current datasheet to confirm package type and temperature range specifications. Ensure compatibility with existing 18-bit wide bus architectures. Confirm that the 68-pin PLCC footprint matches the target PCB design. Cross-reference electrical characteristics such as supply voltage and current consumption with system requirements before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when an 18-bit data path and 256-word depth are required for buffering applications. It is suitable for designs needing independent read and write clocks with high-speed performance up to 100 MHz. Consider this part over wider or deeper FIFOs if board space and power consumption are constrained. Verify that the TTL-compatible logic levels align with the interfacing microprocessor or FPGA I/O standards.

FIFOs Memory Part Context

This component belongs to the CY7C42X5 family of synchronous FIFOs, which includes variants with depths ranging from 64 to 4K words. All members of this family share pin and functional compatibility with IDT722x5 devices. The family is designed to provide flexible data buffering solutions with consistent interface characteristics across different memory depths.

FIFOs Memory Replacement Considerations

The CY7C4205-15ASC is functionally compatible with the IDT7225 series. Designers may consider equivalent parts from other manufacturers that offer 256 x 18 synchronous FIFO configurations with identical pinouts and timing parameters.
