description
The TMS416100/P series are high-speed, 16777216-bit dynamic random-access memories, organized as
16777216 words of one bit each. The TMS416100P series feature self refresh and extended refresh. They
employ state-of-the-art EPIC (Enhanced Performance Implanted CMOS) technology for high performance,
reliability, and low power at a low cost.
These devices feature maximum RAS access times of 60 ns, 70 ns, and 80 ns. All inputs, outputs, and 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 TMS416100/P are offered in 300-mil 24/26-lead plastic surface-mount SOJ packages (DJ suffix) and
24/26-lead plastic small-outline packages (DGA suffix). All packages are characterized for operation from 0°C
to 70°C.
