7203L40LB

Overview

The Renesas 7203L40LB is a dual-port asynchronous FIFO memory device with an organization of 2K x 9 bits. It operates at a maximum data rate of 20MHz and features an access time of 40ns. The component supports a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 150mA. It utilizes Full and Empty flags for flow control and is housed in a 32-lead LCC package.

Feature Summary

• Dual-port architecture enabling independent read and write operations
• Asynchronous interface supporting flexible system integration
• Hardware flow control via Full and Empty status flags

Applications

• Data buffering between components operating at different clock speeds
• Interface bridging in high-speed digital communication systems
• Temporary storage in embedded processing applications

Procurement Notes

Verify the specific suffix LB against official Renesas documentation to confirm package type and temperature range. Ensure compatibility with 5V logic levels and check for RoHS compliance status prior to ordering. Confirm availability through authorized channels as distribution terms vary.

Selection Notes

Select this component when a 2K x 9 asynchronous buffer is required with 40ns access speed. Consider the 32-lead LCC package constraints and 5V supply requirements. Evaluate if the 20MHz data rate meets system throughput needs compared to faster alternatives.

Part Context

Part of the Renesas 7203 series of dual-port FIFO memories. This series provides versatile buffering solutions for various industrial and consumer electronics applications requiring reliable data transfer between asynchronous domains.

Replacement Considerations

The 7203L25P offers similar functionality with a faster 25ns access time but uses a PDIP package. Verify pinout compatibility and package dimensions before substitution.
