IDT7024L20PFGI

Dual-Port SRAM, 4KX16, 20ns, CMOS, PQFP100, 14 X 14MM, 1.4MM HEIGHT, GREEN, TQFP-100

Description

The IDT7024 is a high-speed 4Kx 16 Dual-Port Static RAM. The IDT7024 is designed to be used as a stand-alone 64K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit or more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications results in full-speed, error free operation without the need for additional discrete logic.
