72231L25PFI

Overview

The Renesas Electronics Corporation 72231L25PFI is a synchronous First-In, First-Out (FIFO) memory device with a storage capacity of 18K bits, organized as 2K words by 9 bits. It features a typical access time of 10 ns and operates at data rates up to 66.7 MHz. The component supports independent read and write clocks and utilizes a dual-ported zero fall-through time architecture. It functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 60 mA. The device is housed in a 32-LQFP package and is rated for an operating temperature range of -40°C to +85°C.
