72V841L20TFGI8

FIFOs Memory Overview

The 72V841L20TFGI8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 72K bits, organized as two independent 4K x 9 bit FIFOs within a single package. The component supports a maximum data rate of 50MHz with an access time of 12ns. It operates on a 3.3V supply voltage and is housed in a 64-pin TQFP (10x10) surface-mount package. This dual-port architecture allows for separate control and data lines for each FIFO.

FIFOs Memory Feature Summary

• Dual independent synchronous FIFO architecture with separate control and data lines
• Supports both single-clock and asynchronous dual-clock operation modes
• Programmable Almost-Empty and Almost-Full flags for precise buffer management
• Output data lines enter high-impedance state when enabled

FIFOs Memory Applications

• Data prioritization systems requiring bidirectional transfer
• Width expansion applications in digital signal processing
• Buffering between asynchronous clock domains
• High-speed interface bridging in communication equipment

FIFOs Memory Procurement Notes

Verify the specific suffix 'L20TFGI8' to confirm the 12ns access time and industrial temperature grade. Confirm RoHS compliance status as indicated by the 'G' suffix. Check current product status as this series may be obsolete or subject to last-time buy notices. Ensure the 64-TQFP package dimensions match the PCB footprint requirements before ordering.

FIFOs Memory Selection Notes

Select this component when dual independent FIFOs are required in a compact form factor. It is suitable for designs needing 9-bit data width buffering at speeds up to 50MHz. Consider the 3.3V logic level compatibility with the host system. Verify that the 12ns access time meets the timing constraints of the application's clock domain.

FIFOs Memory Part Context

This part belongs to the 72V841 family of dual synchronous FIFOs from Renesas. The family offers various speed grades and package options. The 72V841L20TFGI8 specifically denotes the 12ns speed variant in a lead-free TQFP package. It is functionally equivalent to two 72V241 FIFOs integrated into one chip, providing design flexibility for space-constrained applications.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the 72V841 series with different speed grades (e.g., L10, L15). Verify if newer generations from Renesas offer similar dual FIFO functionality with improved specifications. Ensure any replacement maintains the 64-TQFP package and 3.3V operating voltage.
