( DataSheet : www.DataSheet4U.com ) E2G0014-17-41 ¡ Semiconductor MSM511664C/CL ¡ Semiconductor This version: Jan. 1998 MSM511664C/CL Previous version: May 1997 65,536-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE (BYTE WRITE) DESCRIPTION The MSM511664C/CL is a 65,536-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate CMOS technology. The MSM511664C/CL achieves high integration, high-speed operation, and low-power consumption because Oki manufactures the device in a quadruple-layer polysilicon/single-layer metal CMOS process. The MSM511664C/CL is available in a 40-pin plastic SOJ or 44/40-pin plastic TSOP. The MSM511664CL (the low-power version) is specially designed for lower-power applications. FEATURES 65,536-word ¥ 16-bit configuration Single 5 V power supply, ± 10% tolerance Input : TTL compatible, low input capacitance Output : TTL compatible, 3-state Refresh : 256 cycles/4 ms, 256 cycles/32 ms (L-version) Byte write and fast page mode, read modify write capability CAS before RAS refresh, hidden refresh, RAS-only refresh capability Package options: 40-pin 400 mil plastic SOJ (SOJ40-P-400-1.27) (Product : MSM511664C/CL-xxJS) 44/40-pin 400 mil plastic TSOP (TSOPII44/40-P-400-0.80-K) (Product : MSM511664C/CL-xxTS-K) xx indicates speed rank.
