MSM514265C/CSL
262,144-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM514265C/CSL is a 262,144-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM514265C/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 MSM514265C/CSL is available in a 40-pin plastic SOJ or 44/
40-pin plastic TSOP. The MSM514265CSL (the self-refresh version) is specially designed for lower-
power 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 with EDO, 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 : MSM514265C/CSL-xxJS)
44/40-pin 400 mil plastic TSOP (TSOPII44/40-P-400-0.80-K) (Product : MSM514265C/CSL-xxTS-K)

Notes for Mounting the Surface Mount Type Package
The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which
are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki’s responsible sales person for the
product name, package name, pin number, package code and desired mounting conditions
(reflow method, temperature and times).
