7202LA35J

Overview

The Renesas Electronics Corporation 7202LA35J is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates with a maximum data rate of 22.2MHz and has an access time of 35ns. The device supports unidirectional bus directionality and includes relay capability. It functions within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 80mA. The component is housed in a 32-PLCC package (14x11.46mm) designed for surface mount installation.

Feature Summary

Asynchronous operation allowing independent read and write clock domains
Built-in relay capability for signal buffering and isolation
Standard CMOS parallel interface architecture

Applications

Data buffering between asynchronous logic systems
Clock domain crossing interfaces
High-speed data acquisition systems

Procurement Notes

Verify the specific suffix 'J' indicates the commercial temperature range variant, as datasheets may list industrial ranges. Confirm RoHS compliance status, as older Renesas parts often lack it. Check for active obsolescence notices or PCNs affecting pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this part when a 9K depth and 9-bit width are required for asynchronous buffering. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 35ns access time against system timing requirements. Verify if the PLCC package form factor fits the PCB layout constraints compared to alternative packages like LCC.

Part Context

This component belongs to the IDT 7200 series of high-performance asynchronous FIFOs. It is manufactured by Renesas Electronics Corporation, following the acquisition of Integrated Device Technology. The 7202LA35J represents a specific speed grade within the 7202LA family, distinguished by its 35ns access time and 32-pin PLCC packaging.
