72V821L20PFG8

FIFOs Memory Overview

The 72V821L20PFG8 is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics. It provides a storage capacity of 18 kilobits, organized as 1K x 9 x 2. The component supports bidirectional data bus direction and operates with a maximum data rate of 66.7 MHz. Access time is specified at 10 ns. It functions within a supply voltage range of 3 V to 3.6 V and draws a maximum supply current of 40 mA. The device is housed in a 64-TQFP package measuring 14x14 mm and is rated for an operating temperature range from 0°C to +70°C.

FIFOs Memory Feature Summary

• Supports bidirectional data flow for flexible system integration
• Provides programmable flags for status monitoring
• Enables depth and width expansion capabilities

FIFOs Memory Applications

• Data buffering in telecommunications systems
• Interface bridging between asynchronous logic domains
• High-speed data acquisition systems

FIFOs Memory Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm package type and moisture sensitivity level. Ensure compatibility with the required 3.3 V power supply domain. Confirm that the 64-TQFP footprint matches the target PCB design. Check for RoHS compliance status if environmental regulations apply to the end product.

FIFOs Memory Selection Notes

Select this component when bidirectional FIFO functionality is required with a 1K x 9 configuration. It is suitable for applications needing 10 ns access times and operation up to 66.7 MHz. Consider the 64-TQFP package size for space-constrained designs. Verify that the 0°C to +70°C industrial temperature range meets the operational environment requirements.

FIFOs Memory Part Context

This part belongs to the 72V series of high-performance FIFO memories. These devices are designed for buffering data in digital signal processing and communication interfaces. The 72V821 variant specifically offers dual-port capability with bidirectional support, distinguishing it from unidirectional counterparts in the same family.
