72V231L20J8

FIFOs Memory Overview

The 72V231L20J8 is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics. It features a storage organization of 2K words by 9 bits, providing a total capacity of 18 kilobits. The component operates with a maximum clock frequency of 50 MHz and supports a data rate of 50 Mbps. It has a typical access time of 20 nanoseconds. The device functions within a supply voltage range of 3.0 V to 3.6 V. It is housed in a 32-pin PLCC package.

FIFOs Memory Feature Summary

• Supports dual-clock operation where read and write clocks can run asynchronously or be tied together for single-clock synchronization.
• Provides independent read and write control signals for flexible interface integration.

FIFOs Memory Applications

• Graphics buffering
• Local area network data handling
• Interprocessor communication

FIFOs Memory Procurement Notes

Verify the current lifecycle status before design finalization, as this component may be discontinued or subject to limited availability. Confirm RoHS compliance requirements against specific project standards, noting that some listings indicate non-compliance. Ensure the 32-PLCC package footprint matches the target PCB layout constraints. Validate moisture sensitivity levels for proper storage and reflow soldering profiles.

FIFOs Memory Selection Notes

Select this component when a 2K x 9 synchronous FIFO is required for 3.3V logic systems. It is suitable for applications needing 20 ns access times and 50 MHz operation speeds. Consider the PLCC package if through-hole or specific surface-mount compatibility is necessary. Evaluate alternative pin-compatible devices if lead-free compliance is mandatory for the target market.

FIFOs Memory Part Context

This part belongs to the 72V231 series of synchronous FIFO memories from Renesas Electronics. It serves as the 3.3V version of the earlier 72231 device. The series is designed for high-speed data buffering tasks requiring reliable first-in, first-out data management in digital systems.
