MSM5416258A
262,144-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM5416258A is a 262,144-word ¥ 16-bit dynamic RAM fabricated in Oki's CMOS silicon gate
technology. The MSM5416258A achieves high integration, high-speed operation, and low-power
consumption because Oki manufactures the device in a quadruple-layer polysilicon/double-layer
metal CMOS process. The MSM5416258A is available in a 44/40-pin plastic TSOP.
FEATURES
• 262,144-word ¥ 16-bit configuration
• Single 5.0 V power supply, ±0.5 V tolerance
• Input:
TTL compatible
• Output: TTL compatible, 3-state
• Refresh: 512 cycles/8 ms
• Fast page mode with EDO, read modify write capability
• Byte wide control: 2 CAS control
• CAS before RAS refresh, hidden refresh, RAS only refresh capability
• Package :
44/40-pin 400 mil plastic TSOP (Type II) (TSOPII44/40-P-400-0.80-K) (Product : MSM5416258A-xxTS-K)

Notes for Mounting the Surface Mount Type Package
The SOP, QFP, TSOP, TQFP, LQFP, 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
ontheproductname,packagename,pinnumber,packagecodeanddesiredmountingconditions
(reflow method, temperature and times).
