CY7C420-65PI

FIFOs Memory Overview

The CY7C420-65PI is a synchronous FIFO memory integrated circuit manufactured by Cypress Semiconductor Corp. It features a storage capacity of 512 x 9 bits and operates with a data rate of 12.5MHz. The device has an access time of 65ns and supports unidirectional bus direction. It functions within a voltage range of 4.5 V to 5.5 V and consumes a maximum supply current of 35mA. The component is housed in a 28-PDIP package and is designed for surface mount installation. It supports programmable flags and relay capability, operating within a temperature range of -40°C to 85°C.

FIFOs Memory Feature Summary

• Provides reliable asynchronous data buffering with 512 x 9 bit storage depth
• Supports unidirectional data transfer operations at specified clock speeds
• Includes programmable status flags for precise buffer management

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging in high-speed digital communication systems
• Temporary data storage in embedded control applications

FIFOs Memory Procurement Notes

Verify the specific suffix 'PI' indicates the correct package type and temperature range for your design requirements. Confirm RoHS compliance status as sources indicate non-compliance for some variants. Ensure the supplier provides official datasheets matching the Cypress part number to avoid counterfeit components. Check lead-free status if environmental regulations apply to your assembly process.

FIFOs Memory Selection Notes

Select this component when a unidirectional asynchronous FIFO with 512-word depth is required. The 65ns access time suits moderate-speed interface applications. Compare against the CY7C420-40PC if faster performance is needed. Consider the 28-PDIP package constraints for PCB layout. Verify power supply stability within the 4.5V to 5.5V range for reliable operation.

FIFOs Memory Part Context

This part belongs to the CY7C420 series of asynchronous FIFOs from Cypress Semiconductor. The series offers various depths and speeds, with the CY7C420-65PI specifically providing 512x9 configuration. It complements other memory solutions like the CY7C421 synchronous series. The product line targets general-purpose buffering needs in industrial and consumer electronics.

FIFOs Memory Replacement Considerations

The CY7C420-40PC is a verified substitute offering faster 40ns access time with identical 512x9 capacity and pinout compatibility.
