DP802518 TROPIC TsunamiTM
TROPIC IITM Microcode ROM
General Description
The DP802518 Tsunami is the microcode device for the
high performance Token Ring Protocol Interface Control-
ler TROPIC II Token Ring chipset this device features an
interface compatible to the DP80253 controller which al-
lows direct connection without the use of glue logic
The DP802518 Tsunami is implemented using National
Semiconductor’s Advanced CMOS process and operates
from a single 5Vg 10% power supply The Tsunami is avail-
able in either a 28-pin DIP or 32-pin PLCC package
Features
Y TROPIC II compatible
Glueless interface
