CDC 3207G
ARM7-Based Car Dashboard Controller
The CDC 3207G-Cx is a feature- improved,
pin-compatible version of the existing
CDC 3207G-Bx device. Both are members
of Micronasâ 32-bit Car Dashboard Control-
ler family based on an ARM7TDMI CPU
core (CDC 32xxG).
This device comes along with additional
features like a superior power saving mod-
ule (PSM), four high-speed CAN modules
(Bosch V2.0B) and a device lock module to
inhibit Flash access. 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 3207G also contains the patented
built-in ERM (EMI Reduction Module).
