CY7C4255V-15ASI

FIFOs Memory Overview

The CY7C4255V-15ASI 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 Kbits. 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 measuring 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 clocked read and write interfaces
• Supports unidirectional data bus direction for dedicated input or output applications
• Includes programmable status flags to indicate buffer occupancy levels

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 'ASI' against official Cypress documentation to confirm pinout and electrical characteristics match the standard CY7C4255 series. Confirm RoHS compliance status as some variants may differ. Ensure the 64-TQFP package dimensions align with your PCB footprint requirements before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 18-bit width and 8K depth is required. The 15 ns speed grade suits applications operating up to 40 MHz. Consider the 3 V to 3.6 V voltage range for compatibility with low-voltage logic families. Evaluate the 64-TQFP package size for space constraints in surface-mount designs.

FIFOs Memory Part Context

This part belongs to the CY7C4255 family of synchronous FIFOs from Cypress Semiconductor. These devices are designed for high-performance data buffering tasks where precise timing control via a clock signal is necessary. The family offers various depth and speed options to accommodate different bandwidth and latency requirements in digital systems.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the CY7C4255 series with different speed grades or package types. Verify compatibility with IDT722x5 pinouts if migrating from competitor components. Ensure any replacement maintains the 18-bit width and synchronous operation mode.
