72V235L10PFG8

FIFOs Memory Overview

The Renesas 72V235L10PFG8 is a synchronous FIFO memory device belonging to the 72V series. It features a storage capacity of 4K x 18 bits, providing a total data width of 18 bits and a depth of 4096 words. The component operates with a maximum clock frequency of 100 MHz and supports a data rate of 100 Mbps. It utilizes a single power supply voltage range of 3.0 V to 3.6 V. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 14 mm by 14 mm body size.

FIFOs Memory Feature Summary

• Synchronous operation with independent read and write clocks for flexible interface timing
• Supports First-Word-Fall-Through (FWFT) mode for immediate data availability upon read assertion
• Includes programmable flags indicating full, empty, and half-full buffer states
• Bidirectional bus direction control allows configurable data flow between ports

FIFOs Memory Applications

• Data buffering in high-speed serial communication interfaces
• Clock domain crossing synchronization between asynchronous logic blocks
• Frame buffering in video processing pipelines
• Packet buffering in network switch architectures

FIFOs Memory Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm package type and temperature grade. Confirm current production status as discontinuance notices may affect long-term availability. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

FIFOs Memory Selection Notes

Select this component when an 18-bit wide synchronous FIFO is required for buffering applications. Verify that the 3.3 V operating voltage aligns with the system logic levels. Consider the 64-pin TQFP footprint constraints during PCB layout design. Evaluate if the 100 MHz speed meets the target throughput requirements.

FIFOs Memory Part Context

This part belongs to the Renesas 72V family of synchronous FIFOs, designed for high-performance data buffering. The family offers various capacities and widths to suit different system needs. The 72V235 variant specifically addresses applications requiring moderate depth with a fixed 18-bit word width, bridging legacy IDT designs within the Renesas portfolio.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes such as the 72V235L10TF8 if LQFP packaging is acceptable. Verify functional equivalence with other 4Kx18 synchronous FIFOs from alternative manufacturers before substitution.
