MSM518126/L
131,072-Word ¥ 8-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
DESCRIPTION
The MSM518126/L is a 131,072-word ¥ 8-bit dynamic RAM fabricated in Oki's silicon-gate CMOS
technology. The MSM518126/L achieves high integration, high-speed operation, and low-power
consumption because Oki manufactures the device in a quadruple-layer polysilicon/single-layer
metalCMOSprocess. TheMSM518126/Lisavailableina26/24-pinplasticSOJor26/24-pinplastic
TSOP.TheMSM518126L(thelow-powerversion)isspeciallydesignedforlower-powerapplications.
FEATURES
• 131,072-word ¥ 8-bit configuration
• Single 5 V power supply, ±5% tolerance
• Input
: TTL compatible, low input capacitance
• Output : TTL compatible, 3-state
• Refresh : 256 cycles/4 ms, 256 cycles/32 ms (L-version)
• Fast page mode, 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 : MSM518126/L-xxJS)
26/24-pin 300 mil plastic TSOP (TSOPII26/24-P-300-1.27-K) (Product : MSM518126/L-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).
