MSM514260C/CSL

262,144-Word ´ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE

DESCRIPTION

The MSM514260C/CSL is a 262,144-word ´ 16-bit dynamic RAM fabricated in Oki's silicon-gate CMOS technology. The MSM514260C/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 MSM514260C/CSL is available in a 40-pin plastic SOJ or 44/ 40-pin plastic TSOP. The MSM514260CSL (the self-refresh version) is specially designed for lowerpower applications.

FEATURES

•262,144-word ´ 16-bit configuration

•Single 5 V power supply, ±10% tolerance

• Input	: TTL compatible, low input capacitance
• Output	: TTL compatible, 3-state
• Refresh	: 512 cycles/8 ms, 512 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:

40-pin 400 mil plastic SOJ	(SOJ40-P-400-1.27)	(Product : MSM514260C/CSL-xxJS)
44/40-pin 400 mil plastic TSOP	(TSOPII44/40-P-400-0.80-K) (Product : MSM514260C/CSL-xxTS-K)
		xx indicates speed rank.
