System Architecture

The Car Dashboard Controller CDC 3272G

contains an embedded ARM7TDMI proces-

sor which operates at a maximum clock fre-

quency of 50 MHz.

The internal high-speed bus connects the

following peripherals to the ARM7TDMI pro-

cessor:

The 16/32-bit bus connects to the mask

ROM. All other peripherals are connected to

the I/O bus. All I/O ports have multiple func-

tions to obtain utmost flexibility. A total of

102 GPIOs can be selected.

The built-in ERM delivers superb EMI

results reducing the peak values by up to

10 dB

µV.

The CDC 3272G is fully pin- and software-

compatible with all other members of the

CDC 32xxG family.
