72V231L10J

FIFOs Memory Overview

The Renesas 72V231L10J is a synchronous First-In, First-Out (FIFO) memory device with a 2K x 9 organization. It operates on a 3.3V supply voltage ranging from 3.0V to 3.6V. The component features independent read and write clocks, allowing for dual-clock asynchronous operation or single-clock synchronization. It utilizes a zero fall-through time architecture and provides programmable status flags including empty, full, almost-empty, and almost-full indicators. The device is housed in a 32-pin PLCC package.

FIFOs Memory Feature Summary

• Dual-clock capability with independent read and write clock inputs
• Zero fall-through time architecture for immediate data availability
• Programmable status flags for buffer management
• High-speed synchronous interface

FIFOs Memory Applications

• Graphics data buffering
• Local area network interfaces
• Interprocessor communication links

FIFOs Memory Procurement Notes

Verify the specific suffix 'J' against official Renesas documentation to confirm package type and temperature range. Confirm RoHS compliance status as older variants may differ. Check for end-of-life notices or obsolescence warnings before procurement planning.

FIFOs Memory Selection Notes

Select this component when a 3.3V logic level FIFO is required for buffering high-speed data streams. Ensure system design supports independent clock domains if asynchronous operation is intended. Verify that the 32-pin PLCC package fits the target PCB layout constraints.

FIFOs Memory Part Context

This part belongs to the 72V231 family of synchronous FIFOs. It serves as the 3.3V version of the 5V 72231 device. The family is designed for applications requiring reliable data buffering between components operating at different speeds or clock domains.

FIFOs Memory Replacement Considerations

The 72V231L10PFG is a documented alternative within the same family offering similar specifications in a TQFP package. Verify pin compatibility and electrical parameters before substitution.
