CDC 3272G

ARM7-Based Car Dashboard Controller

The CDC 3272G-Cx is a pin-compatible

mask ROM derivative of Micronasâ 32-bit

Car Dashboard Controller family based on

an ARM7TDMI CPU core (CDC 32xxG).

This device comes along with additional

features of the Cx platform like a superior

power saving module (PSM) and two high-

speed CAN module (Bosch V2.0B). Main

characteristics of the PSM are three addi-

tional low-power modes (IDLE, WAKE, and

STANDBY), an internal RC oscillator, a poll-

ing/Flash timer output, as well as an RTC

(Real Time Clock).

The CDC 3272G also contains the patented

built-in ERM (EMI Reduction Module).
