www.DataSheet4U.com E2G0021-17-41 ¡ Semiconductor MSM512805C ¡ Semiconductor This version: Jan. 1998 MSM512805C Previous version: May 1997 262,144-Word ¥ 8-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO DESCRIPTION The MSM512805C is a 262,144-word ¥ 8-bit dynamic RAM fabricated in Oki's silicon-gate CMOS technology. The MSM512805C 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 MSM512805C is available in a 26/24-pin plastic SOJ or 26/24-pin plastic TSOP. FEATURES 262,144-word ¥ 8-bit configuration Single 5 V power supply, ± 5% tolerance Input : TTL compatible, low input capacitance Output : TTL compatible, 3-state Refresh : 512 cycles/8 ms Fast page mode with EDO, read modify write capability CAS before RAS refresh, hidden refresh, RAS-only refresh capability Package options: 26/24-pin 300 mil plastic SOJ (SOJ26/24-P-300-1.27) (Product : MSM512805C-xxJS) 26/24-pin 300 mil plastic TSOP (TSOPII26/24-P-300-1.27-K) (Product : MSM512805C-xxTS-K) xx indicates speed rank.
