MSM512805C
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.
