E2G0024-17-42 ¡ Semiconductor ¡ Semiconductor MSM514800C/CSL DESCRIPTION This MSM514800C/CSL version: Jan. 1998 Previous version: May 1997 524,288-Word ¥ 8-Bit DYNAMIC RAM : FAST PAGE MODE TYPE The MSM514800C/CSL is a 524,288-word ¥ 8-bit dynamic RAM fabricated in Oki's silicon-gate CMOS technology. The MSM514800C/CSL 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 MSM514800C/CSL is available in a 28-pin plastic SOJ or 28pin plastic TSOP. The MSM514800CSL (the self-refresh version) is specially designed for lowerpower applications. FEATURES 524,288-word ¥ 8-bit configuration Single 5 V power supply, ± 10% tolerance Input : TTL compatible, low input capacitance Output : TTL compatible, 3-state Refresh : 1024 cycles/16 ms, 1024 cycles/128 ms (SL version) Fast page mode, read modify write capability CAS before RAS refresh, hidden refresh, RAS-only refresh capability CAS before RAS self-refresh capability (SL version) Package options: 28-pin 400 mil plastic SOJ (SOJ28-P-400-1.27) (Product : MSM514800C/CSL-xxJS) 28-pin 400 mil plastic TSOP (TSOPII28-P-400-1.27-K) (Product : MSM514800C/CSL-xxTS-K) xx indicates speed rank.
