CDC 1651F-E
16-Bit Automotive CAN Controller
The CDC 1651F-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 1651F-E offers 4 Kbytes of RAM
and 128 Kbytes of ROM and 2 Kbytes of
Special Function ROM. The device can be
operated with an external quartz, at clock
frequencies from 4 to 12 MHz. Communica-
tion 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 avail-
able to reduce power consumption signifi-
cantly.
The device also contains the patented built-
in ERM (EMI Reduction Module).
