The CDC 1631F-E is a pin-compatible mask ROM derivative of Micronas’ 16-bit Car Dashboard Controller family based on a WDC 65C816 CPU core.

The CDC 16xyF offers 2 Kbytes of RAM and 64 Kbytes of ROM. The device can be operated with an external quartz, at clock frequencies from 4 to 12 MHz. Communication is possible via one FullCAN module according to Bosch specification V2.0B. Only one single 5 V power supply is needed. Two low-power modes are available to reduce power consumption significantly.

The device also contains the patented built-in ERM (EMI Reduction Module).

System Architecture

The Car Dashboard Controller CDC 1631F-E contains a WDC 65C816 processor which operates at a maximum clock frequency of 12 MHz. An internal RC oscillator can provide an alternative clock signal to the RTC during power saving modes.

All I/O ports have multiple functions to obtain utmost flexibility. A total of 85 GPIOs can be selected.

The built-in ERM delivers superb EMI results reducing the peak values by up to 10 dBmV.

The CDC 1631F-E is fully pin- and software compatible to all other members of the CDC 16xyF family.
