72231L25PFG

Overview

The Renesas Electronics 72231L25PFG is an obsolete asynchronous and synchronous FIFO memory device. It features a storage organization of 2k x 9 bits. The component supports data rates up to 40MHz with an access time of 15ns. It operates within a voltage range of 4.5V to 5.5V and functions at temperatures between -40°C and +85°C. The unit is housed in a PLCC-32 package.

Feature Summary

Supports both asynchronous and synchronous operation modes for flexible system integration
Provides 2k x 9 bit memory capacity for data buffering applications
Operates reliably across extended industrial temperature ranges

Applications

Data buffering in high-speed digital systems
Interface bridging between components with different clock domains
Temporary storage in communication protocols requiring low latency

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Procurement requires verification of availability through authorized distributors or secondary market suppliers. Buyers must confirm the specific revision level and physical condition of available units, as production has ceased. Compliance with current environmental regulations should be verified against the original datasheet specifications before integration into new designs.

Selection Notes

Engineers selecting this part should note its dual asynchronous/synchronous capability and 15ns access time. The 5V supply requirement and PLCC-32 package define the board layout constraints. Due to its obsolete status, alternative solutions with similar performance metrics and modern packaging options are recommended for new product development to ensure long-term supply stability.

Part Context

The 72231L25PFG belongs to the IDT 72231 series of FIFO memories manufactured by Renesas Electronics. This series was designed for high-performance data handling tasks. The device utilizes standard CMOS technology to achieve its specified speed and power characteristics. It represents a legacy solution for parallel data transfer applications prior to the widespread adoption of newer interface standards.
