Overview
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.
