description
The TMS45160 series are high-speed, 4 194 304-bit dynamic random-access memories organized as 262 144
words of 16 bits each. The TMS45160P series are high-speed, low-power, self-refresh 4 194 304-bit dynamic
random-access memories organized as 262 144 words of 16 bits each. They employ state-of-the-art EPIC
( Enhanced Performance Implanted CMOS) technology for high performance, reliability, and low power at low
cost.
These devices feature maximum RAS access times of 60 ns, 70 ns, and 80 ns. Maximum power dissipation
is as low as 770 mW operating and 11 mW standby on 80-ns devices. All inputs and outputs, including clocks,
are compatible with Series 74 TTL. All addresses and data-in lines are latched on chip to simplify system design.
Data out is unlatched to allow greater system flexibility.
The TMS45160 and TMS45160P are each offered in a 40-lead plastic surface-mount SOJ package ( DZ suffix)
and a 40/44-lead plastic surface-mount small-outline ( TSOP ) package ( DGE suffix). These packages are
characterized for operation from 0
°C to 70°C.
