CY7C4275V-10ASC

FIFOs Memory Overview

The CY7C4275V-10ASC is a 3.3V synchronous FIFO memory with a density of 32K x 18 bits, totaling 576K bits. It operates at a maximum frequency of 100 MHz with an access time of 8 ns and a cycle time of 10 ns. The device supports simultaneous read and write operations using independent clocks. It features programmable Almost Full and Almost Empty flags, retransmit capability, and depth expansion via cascade pins. Power consumption is specified at 30 mA active current and 4 mA standby current.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read and write operations with independent clock inputs.
• Includes programmable status flags for Almost Full and Almost Empty conditions alongside standard Empty and Full indicators.
• Enables depth expansion through dedicated cascade input and output pins for connecting multiple devices.
• Provides a retransmit function to reset the internal read pointer for data packet acknowledgment.

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and pin alignment for the 64-pin TQFP form factor. Ensure voltage supply levels match the 3.3V requirement before installation. Review end-of-life documentation as availability may be restricted.

FIFOs Memory Selection Notes

Select this component when a 32K x 18 word capacity is required for buffering applications. Choose this part if independent read and write clocks are necessary for asynchronous operation. Consider this device for designs requiring programmable flag offsets or depth expansion capabilities beyond single-device limits.

FIFOs Memory Part Context

This component belongs to the CY7C42X5V family of low-voltage deep synchronous FIFOs. It shares pin compatibility with other densities in the series, allowing for density upgrades without redesigning the board layout. The device utilizes 0.35 micron CMOS technology for optimized speed and power efficiency.

FIFOs Memory Replacement Considerations

Pin-compatible alternatives within the same family include CY7C4255V, CY7C4265V, and CY7C4285V. These parts offer different storage depths while maintaining identical interface characteristics and package dimensions.
