7202LA20TP

Overview

The Renesas 7202LA20TP is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It supports unidirectional data transfer at a maximum clock frequency of 33.3MHz and features a typical access time of 20ns. The component operates on a single 5V power supply within the range of 4.5V to 5.5V, drawing a maximum supply current of 80mA. It is housed in a 32-PLCC surface-mount package and functions reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous dual-clock architecture for independent read and write operations
• Supports word width expansion from 8-bit to 9-bit configurations
• Includes programmable full and empty status flags for flow control
• Integrated relay capability allows cascading for deeper memory depths

Applications

• Data buffering between components operating at different clock speeds
• Interface bridging in high-speed digital signal processing systems
• Temporary data storage in telecommunications equipment
• Memory management in industrial automation controllers

Procurement Notes

Verify the specific suffix 'TP' against official Renesas documentation to confirm it denotes the standard tube packaging variant rather than a specialized tape-and-reel configuration. Ensure the procurement order explicitly matches the 7202LA20TP designation to avoid confusion with other pin-compatible variants like the LA20J or LA20SO. Confirm RoHS compliance status for the specific manufacturing lot prior to finalizing orders.

Selection Notes

Select this component when a 9-bit data path is required for applications such as video processing or error-correcting code implementations. The 20ns speed grade offers a balance between performance and power consumption suitable for general-purpose logic interfacing. Consider the 32-pin PLCC package constraints regarding PCB layout density and thermal dissipation requirements during the design phase.

Part Context

This part belongs to the IDT 7200L series of asynchronous FIFO memories, originally developed by Integrated Device Technology and now manufactured by Renesas Electronics. The series provides flexible memory solutions for system designers needing reliable data synchronization. The 7202LA20TP specifically addresses needs for moderate-speed, wide-data-path buffering in embedded systems.

Replacement Considerations

Cross-reference with IDT7202LA20TP or IDT7202LA20J for functional equivalence. Verify that any substitute maintains the same 9-bit data width and 32-PLCC footprint. Check for differences in propagation delay tolerances and power supply current specifications before implementation.
