CY7C4255V-15ASC

FIFOs Memory Overview

The CY7C4255V-15ASC is a synchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features an 8K x 18 bit organization, providing a total storage capacity of 144 kilobits. The component supports a data rate of 40 MHz with a maximum access time of 15 ns. It operates on a single 3 V to 3.6 V power supply and draws a maximum supply current of 30 mA. The device is housed in a 64-TQFP package (10x10 mm) and functions within a commercial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Synchronous first-in first-out memory architecture with unidirectional bus direction
• Supports retransmit functionality for data integrity management
• Capable of depth and width expansion for scalable system design

FIFOs Memory Applications

• High-speed data buffering in communication systems
• Multiprocessor interface data synchronization
• Data acquisition system temporary storage

FIFOs Memory Procurement Notes

Verify the specific suffix 'ASC' against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics. Ensure the procurement source provides valid traceability documentation. Confirm that the RoHS status aligns with project requirements, as older batches may differ from current production standards. Validate the package type matches the PCB footprint exactly.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 18-bit word width and 8K depth is required. The 15 ns access time suits applications operating at frequencies up to 40 MHz. Consider the 64-TQFP package constraints for board layout. Verify that the 3 V to 3.6 V voltage range matches the system logic levels. Compare against asynchronous alternatives if clock domain crossing is not managed by the system clock.

FIFOs Memory Part Context

This part belongs to the CY7C42X5 family of low-voltage synchronous FIFOs. The family includes variants with different depths such as 64, 256, 512, 1K, 2K, and 4K words. These devices are designed for high-speed, low-power applications and offer programmable flags like Almost Full and Almost Empty. They are pin-compatible with certain legacy IDT devices, facilitating migration in existing designs.
