7204L35TP

Overview

The Renesas Electronics Corporation 7204L35TP is an asynchronous FIFO memory device belonging to the 7200 series. It features a storage organization of 4K words by 9 bits, providing a total capacity of 36 kilobits. The component supports unidirectional data transfer with a maximum access time of 35 nanoseconds and operates at a data rate of 22.22 MHz. It functions within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 120 mA. The device is housed in a 32-pin PLCC package with J-leads and is designed for industrial temperature ranges.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes auto-retransmit capability allowing reset of the read pointer to its initial position
• Utilizes Full and Empty status flags to prevent data overflow and underflow conditions

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate matching between components operating at different clock speeds
• Data acquisition systems needing temporary storage before processing

Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued or obsolete. Confirm specific suffix requirements for package type and temperature grade against official datasheets. Check for RoHS compliance status and ensure replacement parts maintain functional compatibility with existing system designs.

Selection Notes

Select this component when a 4K x 9 word depth is required for asynchronous buffering. Ensure the design accommodates the 32-PLCC surface mount package constraints. Verify that the 35 ns access time meets the system timing requirements and that the 4.5 V to 5.5 V supply voltage aligns with available power rails.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFO memories, which are designed for high-speed data buffering in digital systems. The series offers various densities and access times, with the 7204 variant specifically providing 36Kb capacity.
