72V845L20PF

FIFOs Memory Overview

The Renesas 72V845L20PF is a synchronous dual-port FIFO memory IC providing 144 kbit capacity, organized as two independent 4K x 18-bit blocks. It operates on a single 3.0 V to 3.6 V supply with a maximum clock frequency of 50 MHz and an access time of 12 ns. The device supports bidirectional data buses and features full water-full/empty flag outputs. It is housed in a 128-pin TQFP package (14x20 mm) and functions within a commercial temperature range of 0°C to +70°C.

FIFOs Memory Procurement Notes

This component is officially discontinued by the manufacturer. Verify end-of-life notices and check for available stock from authorized distributors or secondary market suppliers. Ensure compatibility with existing designs before procurement due to potential obsolescence constraints.

FIFOs Memory Selection Notes

Select this part for applications requiring high-density dual-port synchronization with 18-bit word widths. Compare against single-port alternatives if only one direction is needed. Consider pin count and package size requirements for the 128-TQFP form factor during PCB layout planning.

FIFOs Memory Part Context

Part of the 72V series synchronous FIFO family, designed for high-performance buffering. Similar models include the 72V235L20PF and 72V85L20PA, offering different capacities and asynchronous/synchronous variants within the same ecosystem.

FIFOs Memory Replacement Considerations

Official substitutes are not explicitly listed in public documentation. Evaluate cross-reference options such as the IDT72V845L20PF or compatible industrial-grade FIFOs with matching 4Kx18 organization and 12ns access times.
