7200L12J

Overview

The Renesas Electronics Corporation 7200L12J is an asynchronous FIFO memory device featuring a 256 x 9 bit organization and a 32-pin PLCC package. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum access time of 12 ns and a clock frequency up to 50 MHz. The component supports unidirectional data transfer and functions across a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• CMOS parallel interface architecture
• Standard TTL-compatible logic levels

Applications

• Data buffering in high-speed digital systems
• Protocol conversion between different bus speeds
• Interface bridging in telecommunications equipment

Procurement Notes

Verify the exact suffix designation (e.g., JG or J8) as the base model number may refer to multiple package variants. Confirm RoHS compliance status and moisture sensitivity level requirements against current project specifications before ordering. Check for end-of-life notices or obsolescence warnings from the manufacturer.

Selection Notes

Select this component when a 256-word by 9-bit depth is required for temporary data storage. Ensure the system design accommodates the 32-lead PLCC footprint and that the 12 ns access time meets the timing constraints of the target application environment.

Part Context

This part belongs to the 7200L series of asynchronous FIFOs manufactured by Renesas Electronics. The series provides various density and speed options for memory buffering applications. The 7200L12J specifically targets designs requiring moderate capacity with fast access times.
