PRODUCT INFORMATION CDC 1651F-E Aug/2005 CDC 1651F-E 16-Bit Automotive CAN Controller ◆ One comparator 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. Features 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. 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. ◆ 2 Kbytes Special Function ROM The device also contains the patented builtin ERM (EMI Reduction Module). ◆ Digital watchdog ◆ 16-bit free-running counter with three capture/compare modules ◆ Central clock divider ◆ Patch module (up to 10 cells) ◆ Interrupt controller with 16 inputs and 16 priority levels ◆ 1 ×16-bit timer and 2 ×8-bit timer ◆ 128 Kbytes Mask ROM ◆ 4 Kbytes SRAM ◆ Three CPU operation modes (Fast, Slow, Deep Slow) ◆ Two low-power modes (Idle and Wake) ◆ RTC delivering hours, minutes, seconds ◆ Polling/Flash timer output ◆ 4- to 12-MHz oscillator ◆ EMI reduction module (ERM) ◆ Four port interrupts ◆ Regulator input supervision for reset/ alarm (alarm comparator) ◆ Clock and supply supervision ◆ 9-channel 10-bit ADC ◆ 48 × 4 LCD module ◆ DMA ◆ Two UARTs ◆ Two SPIs ◆ One CAN module with 256 bytes of object RAM according to Bosch specification V2.0B (16 message objects) ◆ Five stepper motor drivers ◆ Five PWM modules ◆ Sound generator with auto decay ◆ Two SW-selectable clock outputs ◆ −40 to +105 °C case temperature range ◆ Single 5 V supply voltage ◆ Up to 85 GPIOs ◆ 100-pin PQFP package, 0.65 mm pin pitch PRODUCT INFORMATION CDC 1651F-E Aug/2005 Development Tools Emulator with Trace or Analyzer and Pattern Generator ◆ Evaluation chip CDC 1605F-E featuring ROM/Flash emulation with external RAM (up to 16 Mbyte) ◆ Emulator and POD with analyzer or trace functionality from 3rd party vendor Parallel, RS232, USB, Ethernet ◆ Application Board (APB) for Flash memory programming ◆ Software environment (compiler, linker, assembler) from 3rd party vendors POD with Target Connector ◆ RTOS from 3rd party vendors Target Fig. 1: Development tool setup System Architecture The Car Dashboard Controller CDC 1651F-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.
