7205L20TP

Overview

The Renesas Electronics Corporation 7205L20TP is an asynchronous FIFO memory device with a storage capacity of 72 kbit, organized as 8K x 9. It features a unidirectional bus and supports a maximum clock frequency of 33.3 MHz with a 20 ns access time. The component operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 120 mA. Designed for industrial applications, it functions between 0°C and +70°C. The integrated circuit is housed in a 28-PDIP package.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Retransmit capability allowing reset of the read pointer to its initial position
• Status flags including Empty, Half-Full, and Full to prevent data overflow and underflow

Applications

• Multiprocessing systems requiring rate buffering
• Data acquisition systems needing temporary storage
• Industrial control interfaces managing asynchronous data streams

Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance. Confirm lead-free availability if required by specific environmental regulations. Check for obsolescence or end-of-life notices from the manufacturer. Ensure the 28-PDIP through-hole package matches the target PCB footprint. Validate that the 4.5V to 5.5V operating voltage aligns with the system power design.

Selection Notes

Select this component when a 72 kbit asynchronous FIFO is required with a 9-bit data width. The 20 ns access speed suits moderate-speed interface buffering. Verify compatibility with existing TTL logic levels. Consider the PDIP-28 package constraints for board layout. Evaluate the 120 mA maximum current consumption against thermal management capabilities.

Part Context

The 7205L20TP belongs to the Renesas 7200 series of high-speed FIFO memories. This family provides dual-port memory solutions designed for multiprocessing and rate matching applications. The device utilizes CMOS technology to achieve low power consumption while maintaining high performance. It serves as a bridge between components operating at different speeds or protocols.
