PRODUCT INFORMATION CDC 3231G May/2005 CDC 3231G ARM7-Based Car Dashboard Controller The new CDC 3231G-Cx is a pin-compatible mask ROM derivative of Micronas' 32-bit Car Dashboard Controller family based on an ARM7TDMI CPU core (CDC 32xxG). The new device comes along with additional features of the Cx platform like a superior power saving module (PSM) and one high-speed CAN module (Bosch V2.0B). 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 device also contains the patented builtin ERM (EMI Reduction Module). Features 128 KB mask ROM 6 KB SRAM Four CPU operation modes (Deep Slow, Slow, Fast, PLL) Three low-power modes (Idle, Wake, Standby) 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 26 inputs and 16 priority levels Five port interrupts Regulator input supervision for reset/ alarm (alarm comparator) Clock and supply supervision 16-channel 10-bit ADC Two comparators ADC reference (1 internal, 3 external) 46x4 LCD module One UART, two SPIs One CAN module with 512 Bytes of object RAM according to Bosch specification V2.0B (32 message objects) One I2C master module Four stepper motor drivers Five PWM modules (configurable as 2x8 bit or 1x16 bit) Sound generator with auto decay Two SW-selectable clock outputs 16-bit free-running counter with four capture/compare modules 1 x16-bit timer and 4x8-bit timer Patch module (up to 10 cells) 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 91 GPIOs 128-pin PQFP package, 0.5 mm pin pitch PRODUCT INFORMATION CDC 3231G 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. 1: Development tool setup System Architecture The Car Dashboard Controller CDC 3231G 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 The 16/32-bit bus connects to the mask 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 91 GPIOs can be selected. The built-in ERM delivers superb EMI results reducing the peak values by up to 10 dBV. The CDC 3231G is fully pin- and softwarecompatible with all other members of the CDC 32xxG family.
