| PRODUCT INFORMATION CDC 3217G May/2005 CDC 3217G ARM7-Based Car Dashboard Controller The CDC 3217G 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), four highspeed 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 3217G also contains the patented built-in ERM (EMI Reduction Module). RTC delivering hours, minutes, seconds Polling/Flash timer output PLL circuitry delivering up to 50 MHz 4- to 5-MHz oscillator EMI reduction module (ERM) Digital watchdog Central clock divider Interrupt controller with 40 inputs and 16 priority levels Six port interrupts Regulator input supervision for reset/ alarm (alarm comparator) Clock and supply supervision 16-channel 10-bit ADC Two I2C master modules Seven stepper motor drivers Six PWM modules (configurable as 2x8 bit or 1x16 bit) Pulse frequency modulator Sound generator with auto decay Two SW-selectable clock outputs 16-bit free-running counter with six capture/compare modules Patch module (up to 10 cells) Device lock module (DLM) inhibiting Flash access 1 x16-bit timer and 4x8-bit timer JTAG interface -40 to +105 C case temperature range Single 3.5 V to 5.5 V supply voltage (limited I/O performance below 4.5 V) Up to 102 GPIOs 128-pin PQFP package, 0.5 mm pin pitch Features 1024 KB Flash 32 KB SRAM 8 KB boot ROM Four CPU operation modes (Deep Slow, Slow, Fast, PLL) Three low-power modes (Idle, Wake, Standby) Two comparators ADC reference (1 internal, 3 external) 48 x4 LCD module Three DMA channels Two UARTs, two SPIs DigitBus master module Four CAN modules with 512 Bytes each of object RAM according to Bosch specification V2.0B (32 message objects) PRODUCT INFORMATION CDC 3217G Development Tools Evaluation chip CDC 3205G featuring - ETM via embedded emulation JTAG - ROM/Flash emulation with external SRAM (up to 8 MBytes) Evaluation Board (EVB) including the CDC 3205G for evaluation and debugging of embedded systems Application Board (APB) for Flash memory programming Probe for PQFP128 Software environment (compiler, linker, assembler) from 3rd party vendors RTOS from 3rd party vendors CAN protocol stacks Logic Analyzer JTAG Probe JTAG JTAG May/2005 ETM Trace Probe EVB Fig. 2: Block diagram of the CDC 3217G System Architecture The Car Dashboard Controller CDC 3217G contains an embedded ARM7TDMI processor which operates at a maximum clock frequency of 50 MHz. The internal high-speed bus connects the following peripherals to the ARM7TDMI processor: ICU (Interrupt Control Unit) SRAM DMA The 16/32-bit bus connects to Flash and boot ROM. All other peripherals are connected to the I/O bus. All I/O ports have multiple functions to obtain utmost flexibility. A total of 102 GPIOs can be selected. The built-in ERM delivers superb EMI results reducing the peak values by up to 10 dBV. The CDC 3217G is fully pin- and softwarecompatible with all other members of the CDC 32xxG family.
