72231L15PFG

Overview

The Renesas 72231L15PFG is a synchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K words by 9 bits. It operates at a maximum data rate of 66.7MHz and features a 10ns access time. The component supports unidirectional bus direction and is powered by a voltage supply ranging from 4.5V to 5.5V, with a maximum supply current of 35mA. It is housed in a 32-LQFP package (7x7mm) and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation with independent read and write clock controls for flexible data buffering
• Programmable status flags including empty, full, half-full, almost-empty, and almost-full indicators
• Supports depth and width expansion for customized memory configurations
• Low power consumption with auto power-down capabilities

Applications

• Data buffering in telecommunications systems
• Interface bridging between asynchronous logic components
• Signal processing applications requiring temporary data storage
• Embedded system memory expansion

Procurement Notes

Verify the specific ordering suffix 'PFG' against the manufacturer's latest datasheet to confirm package type and lead-free status. Ensure compatibility with 4.5V to 5.5V supply rails. Check for end-of-life notifications or alternative recommendations from Renesas Electronics Corporation before finalizing procurement plans.

Selection Notes

Select this component when a unidirectional synchronous FIFO with 9-bit word width is required. It is suitable for designs needing 18K bit capacity with 66.7MHz performance. Consider the 32-LQFP package constraints and 0°C to 70°C industrial temperature range during PCB layout and thermal management planning.

Part Context

This part belongs to the Renesas 7200 series of SuperSync FIFO memories. These devices are designed for high-speed data buffering and protocol conversion. The 72231 variant specifically offers a 2K x 9 configuration, providing a balance between density and speed for various digital signal processing and communication interface applications.

Replacement Considerations

Check for direct pin-compatible replacements within the 72231 family. Verify if upgraded versions with different voltage tolerances or extended temperature ranges are available from Renesas. Cross-reference with IDT equivalents if sourcing from previous distributors.
