System Architecture
The Car Dashboard Controller CDC 3207G
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:
◆
ICU (Interrupt Control Unit)
◆
SRAM
◆
DMA
The 16/32-bit bus connects to Flash and
boot ROM. All other peripherals are con-
nected to the I/O bus. All I/O ports have
multiple functions 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 dBµV.
The CDC 3207G is fully pin- and software-
compatible with all other members of the
CDC 32xxG family.
