72T18105L6-7BB

FIFOs Memory Overview

The Renesas Electronics Corporation 72T18105L6-7BB is a high-performance First-In-First-Out (FIFO) memory device belonging to the 72T series. It features a storage capacity of 2.25 Mbit, organized as 128K x 18 or 256K x 9 bits. The component supports both asynchronous and synchronous Terasync operation modes with a maximum clock frequency of 150 MHz in synchronous mode. It operates on a single 2.5V power supply within a voltage range of 2.375 V to 2.625 V. The device utilizes a unidirectional bus architecture and is housed in a 240-pin Plastic Ball Grid Array (PBGA) package measuring 19x19 mm.
