CDC 3272G
ARM7-Based Car Dashboard Controller
The CDC 3272G-Cx is a pin-compatible
mask ROM derivative of Micronas’ 32-bit
Car Dashboard Controller family based on
an ARM7TDMI CPU core (CDC 32xxG).
◆ RTC delivering hours, minutes, seconds
◆ Polling/Flash timer output
◆ PLL circuitry delivering up to 50 MHz
◆ 4- to 5-MHz oscillator
This device comes along with additional
features of the Cx platform like a superior
power saving module (PSM) and two highspeed CAN module (Bosch V2.0B). Main
characteristics of the PSM are three additional low-power modes (IDLE, WAKE, and
STANDBY), an internal RC oscillator, a polling/Flash timer output, as well as an RTC
(Real Time Clock).
The CDC 3272G also contains the patented
built-in ERM (EMI Reduction Module).

System Architecture
The Car Dashboard Controller CDC 3272G
contains an embedded ARM7TDMI processor which operates at a maximum clock frequency of 50 MHz.
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 functions to obtain utmost flexibility. A total of
102 GPIOs can be selected.
