7204L30LB

Overview

The Renesas Electronics Corporation 7204L30LB is an asynchronous FIFO memory device with a storage capacity of 4K x 9 bits. It operates within a voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 33 MHz. The component features a 30 ns access time and is housed in a 32-LCC package measuring 11.43 x 13.97 mm. It functions as a dual-port memory that loads and empties data on a first-in/first-out basis, utilizing Full and Empty flags for control.

Feature Summary

• Asynchronous dual-port FIFO memory architecture
• First-in/first-out data loading and emptying mechanism
• Hardware-based Full and Empty flag generation

Applications

• Data buffering between asynchronous clock domains
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific suffix LB against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status as historical records indicate non-compliance for this series. Check for active Product Change Notices or End-of-Life notifications prior to procurement to ensure supply chain stability.

Selection Notes

Select this component when a 4K x 9 depth is required for asynchronous data transfer. Ensure the system design accommodates the 32-LCC surface mount package dimensions. Verify that the 4.5 V to 5.5 V operating voltage aligns with the target logic levels and power supply constraints.

Part Context

This part belongs to the IDT 7204 series of CMOS FIFO memories. It is designed for applications requiring reliable data buffering without complex interface logic. The device integrates standard FIFO control signals to simplify system integration and reduce board space requirements.

Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Generic cross-references may not match the specific pinout or timing characteristics of the 7204L30LB.
