7203L15TP

Overview

The Renesas Electronics Corporation 7203L15TP is an asynchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K words by 9 bits. It features a unidirectional bus architecture and supports data rates up to 40MHz with a maximum access time of 15ns. The component operates on a single 5.0V supply voltage within a range of 4.5V to 5.5V and draws a maximum supply current of 120mA. It is housed in a 28-pin PDIP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling
• Includes auto-retransmit capability to reset the read pointer upon low pulse
• Provides status flags including Empty, Half-Full, and Full indicators
• Designed for multiprocessing and rate buffering applications

Applications

• Multiprocessing systems requiring data synchronization
• Rate buffer applications between different speed domains
• Industrial control systems operating in wide temperature ranges

Procurement Notes

Verify the exact suffix configuration against official datasheets, as packaging types such as tube or reel vary by specific part number variant. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Check for end-of-life notifications or discontinuance notices from Renesas Electronics to ensure long-term availability and supply chain stability for production planning.

Selection Notes

Select this component when a unidirectional asynchronous FIFO with 9-bit word width is required. Ensure the design accommodates the 28-pin PDIP footprint and 5V logic levels. Verify that the 15ns access time meets system timing requirements and that the industrial temperature range aligns with environmental conditions.

Part Context

This device belongs to the 7203 series of asynchronous FIFO memories manufactured by Renesas Electronics. It is functionally compatible with the broader 720X family, allowing for flexible expansion in depth and bit width. The series is designed for high-speed data transfer applications where independent clock domains are present.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the 720X family. Verify electrical parameters and package dimensions before replacing.
