MSM5416125A
131,072-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
DESCRIPTION
The OKI MSM5416125A is a 128K-word ¥ 16-bit dynamic RAM fabricated in OKI's CMOS silicon
gate technology. The MSM5416125A achieves high integration, high-speed operation, and low-
power consumption due to quadruple polysilicon double metal CMOS. The MSM5416125A has
conventional two CAS type 256K ¥ 16 DRAM compatible pinout. The MSM5416125A is available in
a 40-pin plastic SOJ or 44/40-pin plastic TSOP.
FEATURES
• Fast Page Mode Operation
• Byte wide control: 2 CAS control
• 131,072-word ¥ 16-bit organization
• Pin compatible with 2 CAS type 256K ¥ 16 DRAM
• Single 5 V power supply, ±10% tolerance
• CAS before RAS refresh, Hidden refresh, RAS only refresh capability
• Refresh: 512 cycles/8 ms
• Package options:
40-pin 400 mil plastic SOJ
(SOJ40-P-400-1.27)
(Product : MSM5416125A-xxJS)
44/40-pin 400 mil plastic TSOP (Type II) (TSOPII44/40-P-400-0.80-K) (Product:MSM5416125A-xxTS-K)
xx indicates speed rank.
