PRODUCT INFORMATION CDC 3207G May/2005 CDC 3207G ARM7-Based Car Dashboard Controller The CDC 3207G-Cx is a feature- improved, pin-compatible version of the existing CDC 3207G-Bx device. Both are members of Micronas’ 32-bit Car Dashboard Controller family based on an ARM7TDMI CPU core (CDC 32xxG). ◆ Three low-power modes (Idle, Wake, Standby) This device comes along with additional features like a superior power saving module (PSM), four 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). ◆ 4- to 5-MHz oscillator The CDC 3207G 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 ◆ 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 Features ◆ Two comparators ◆ Four CAN modules with 512 Bytes each of object RAM according to Bosch specification V2.0B (32 message objects) ◆ Two I2C master modules ◆ Seven stepper motor drivers ◆ Six PWM modules (configurable as 2×8 bit or 1×16 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 ×16-bit timer and 4×8-bit timer ◆ JTAG interface ◆ −40 to +105 °C case temperature range ◆ 512 KB Flash ◆ ADC reference (1 internal, 3 external) ◆ 32 KB SRAM ◆ 48 ×4 LCD module ◆ Single 3.5 V to 5.5 V supply voltage (limited I/O performance below 4.5 V) ◆ 8 KB boot ROM ◆ Three DMA channels ◆ Up to 102 GPIOs ◆ Four CPU operation modes (Deep Slow, Slow, Fast, PLL) ◆ Two UARTs, two SPIs ◆ 128-pin PQFP package, 0.5 mm pin pitch ◆ DigitBus master module PRODUCT INFORMATION CDC 3207G May/2005 Development Tools ◆ Evaluation chip CDC 3205G featuring JTAG Probe – ETM via embedded emulation JTAG – ROM/Flash emulation with external SRAM (up to 8 MBytes) JTAG JTAG ETM Trace Probe ◆ Evaluation Board (EVB) including the CDC 3205G for evaluation and debugging of embedded systems ◆ Application Board (APB) for Flash memory programming EVB Logic Analyzer ◆ Probe for PQFP128 ◆ Software environment (compiler, linker, assembler) from 3rd party vendors ◆ RTOS from 3rd party vendors Fig. 1: Development tool setup ◆ CAN protocol stacks System Architecture The Car Dashboard Controller CDC 3207G contains an embedded ARM7TDMI processor which operates at a maximum clock frequency of 50 MHz. 32 PLL/ERM RTC 32 KB SRAM Power Saving DMA Contr.
