7205L12JG8

Overview

The Renesas Electronics Corporation 7205L12JG8 is an asynchronous FIFO memory device with a storage capacity of 8K x 9 bits, totaling 72 Kbits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum data rate of 83.3 MHz with a 12 ns access time. The component utilizes a 32-pin PLCC package for surface mount installation.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes auto-retransmit capability to reset the read pointer upon low pulse
• Utilizes Full, Empty, and Half-Full status flags to prevent data overflow and underflow

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 RoHS compliance status as sources indicate conflicting information regarding this specific part number variant. Confirm moisture sensitivity level and lead-free availability directly with the manufacturer or authorized distributors prior to procurement. Ensure the ordering suffix matches the required packaging format.

Selection Notes

Select this component when a 12 ns access time and 8K depth are required for asynchronous buffering. Compare against the 7205L25JI8 if slower speed but similar capacity is acceptable. Verify that the 32-PLCC package fits the target PCB footprint and that the unidirectional bus architecture meets system design requirements.

Part Context

This device belongs to the 7205 series of CMOS parallel FIFO memories. It is functionally compatible with the broader 720X family, sharing pinouts and operational characteristics while offering specific speed and capacity configurations tailored for high-performance digital signal processing and interface buffering tasks.

Replacement Considerations

The IDT7205L12JG is a verified substitute part number. Verify pin compatibility and electrical specifications before implementation.
