CDC 3257G
ARM7-Based Car Dashboard Controller
The CDC 3257G-Cx is a pin-compatible
Flash ROM derivate of Micronas’ 32-bit Car
Dashboard Controller family based on an
ARM7TDMI CPU core (CDC32xxG).
This device comes along with additional
features of the Cx platform like a superior
power saving module (PSM), two 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 3257G also contains the patented
built-in ERM (EMI Reduction Module).
