CY7C451-30LMB

FIFOs Memory Overview

The CY7C451-30LMB is an asynchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a 512 x 9 memory configuration with a 20ns access time and operates at a data rate of 33.3MHz. The component supports unidirectional data transfer and functions within a voltage supply range of 4.5 V to 5.5 V. It is housed in a 32-CLCC package measuring 13.97x11.43 mm.

FIFOs Memory Feature Summary

• Asynchronous first-in first-out memory architecture with clocked read and write interfaces
• High-speed operation supporting 33.3MHz data rates
• Low-power CMOS technology implementation

FIFOs Memory Applications

• Data buffering between systems operating at different clock speeds
• Interface bridging for high-speed digital logic circuits
• Temporary storage in asynchronous communication protocols

FIFOs Memory Procurement Notes

Verify the specific suffix LMB confirms the 32-CLCC ceramic package variant. Confirm the -30 speed grade corresponds to the required 20ns access time for your design. Check current lifecycle status as Cypress components may have discontinued availability or require alternative sourcing from authorized distributors.

FIFOs Memory Selection Notes

Select this part when a 512-word depth with 9-bit width is required for asynchronous buffering. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 32-CLCC package dimensions for PCB layout constraints compared to standard plastic packages.

FIFOs Memory Part Context

This component belongs to the CY7C451 series, which includes high-speed, low-power FIFO memories. The series typically offers various speed grades and package options to accommodate different timing and physical integration requirements in embedded systems and industrial applications.

FIFOs Memory Replacement Considerations

Check for CY7C451 variants with different speed grades or package types if the exact LMB suffix is unavailable. Verify pin compatibility before substituting with other asynchronous FIFOs from the same manufacturer family.
