CY7C421-10JC

FIFOs Memory Overview

The CY7C421-10JC is a synchronous FIFO memory integrated circuit manufactured by Cypress Semiconductor Corp. It features a storage capacity of 512 x 9 bits with a unidirectional bus architecture. The device supports data rates up to 50MHz and offers an access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 85mA. The component is housed in a 32-PLCC package with J-leads, measuring 11.43x13.97mm, and functions reliably across a commercial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Synchronous operation with unidirectional data flow for efficient buffering applications
• Supports programmable status flags for monitoring full and empty conditions
• Surface-mount PLCC packaging designed for automated assembly processes

FIFOs Memory Applications

• Data buffering between asynchronous system components
• Interface bridging in high-speed digital communication systems
• Temporary data storage in microprocessor-based designs

FIFOs Memory Procurement Notes

Verify the specific suffix JC against official Cypress documentation to confirm package type and pinout compatibility. Ensure the operating environment remains within the specified 0°C to 70°C range. Confirm that the 4.5V to 5.5V power supply requirements align with the target system design before integration.

FIFOs Memory Selection Notes

Select this component when a 512-word by 9-bit depth is required for synchronous data handling. The 10ns access time suits moderate-speed interfaces. Consider the 32-PLCC form factor for board layout constraints. Verify that the unidirectional bus direction meets the specific data flow requirements of the application architecture.

FIFOs Memory Part Context

This part belongs to the CY7C series of FIFO memories from Cypress Semiconductor. It provides dedicated hardware buffering capabilities distinct from general-purpose SRAM. The synchronous nature ensures data integrity through clocked operations, making it suitable for timing-critical digital logic applications requiring reliable temporary storage.

FIFOs Memory Replacement Considerations

Check for CY7C421 variants with different speed grades or package options. Verify cross-compatibility with other Cypress CY7C4xx series devices if pinouts match. Consult official substitution guides for any discontinued equivalents.
