7204L15TPI

Overview

The Renesas Electronics Corporation 7204L15TPI is an asynchronous FIFO memory device with a storage capacity of 36 kbit, organized as 4K x 9. It features a unidirectional data bus and supports a maximum clock frequency of 40 MHz with a 15 ns access time. The component operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power consumption of 120 mA. It is housed in a 28-pin PDIP package and functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Unidirectional data transfer capability for standard buffering applications
• Industrial-grade reliability supporting wide ambient temperature variations

Applications

• Multiprocessing systems requiring data synchronization
• Rate matching between components operating at different speeds
• Buffering data streams in communication interfaces

Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be discontinued or subject to obsolescence notices. Confirm that the 28-pin PDIP package aligns with existing board layouts. Ensure compatibility with the required 4.5 V to 5.5 V supply rails and check for any available pin-compatible alternatives if sourcing new units proves difficult.

Selection Notes

Select this component when an asynchronous FIFO with a 9-bit word width and 4K depth is required. It is suitable for designs needing 15 ns access times and 40 MHz operation. Consider the through-hole mounting requirement of the PDIP package against surface-mount options like the SOIC variant if space constraints exist.

Part Context

This device belongs to the 7204L series of asynchronous FIFO memories manufactured by Renesas Electronics. It provides non-volatile-like buffering capabilities without the complexity of synchronous clock alignment. The series is designed for high-speed data handling in digital logic environments.
