The MCS12H-Family of MCUs has the on-chip peripherals needed for your automotive instrumentation designs. In addition, they feature a motor pulse width modulator (MC) module consisting of up to 24 high-current outputs suited to drive up to six stepper motors and on selected devices, up to four stepper stall detectors (SSD) to simultaneously calibrate the pointer reset position of each motor. The MCS12H-Family has full 16-bit data paths throughout and the inclusion of a PLL circuit allows power consumption and performance to be adjusted. In addition to the I/O ports available in each module, up to 14 I/O ports are available with Key-Wake-Up capability from STOP or WAIT mode.

Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_DD) is within the range of 4.5V to 5.5V.
   • Connect a decoupling capacitor (e.g., 100nF) close to the power pins to reduce noise.

2. Clock Configuration:

   • The crystal oscillator frequency (f_XTAL) can be set between 32.768 kHz and 16 MHz.
   • The microcontroller clock frequency (f_MCU) can be configured up to 40 MHz using the internal PLL.

3. Operating Temperature:

   • The device operates reliably within the temperature range of -40°C to 85°C.
   • For storage, ensure temperatures remain between -65°C and 150°C.

4. Input and Output Levels:

   • Input high voltage (V_IH) should be at least 2.0V.
   • Input low voltage (V_IL) should not exceed 0.8V.
   • Output high voltage (V_OH) will be between 4.5V and 5.5V.
   • Output low voltage (V_OL) will be less than or equal to 0.5V.

5. Current Ratings:

   • The output high current (I_OH) is typically 5mA.
   • The output low current (I_OL) is typically -20mA.

6. Timing Parameters:

   • Propagation delay (t_PD) is typically 25ns.
   • Rise time (t_RH) and fall time (t_RF) are typically 10ns each.

7. Low Power Mode:

   • To enter low power mode, configure the appropriate registers to reduce power consumption.
   • In low power mode, the supply current (I_DD) is typically 0.1mA.

8. Programming and Debugging:

   • Use the on-chip debugger and programming interfaces (e.g., BDM) for firmware development and debugging.
   • Refer to the specific application notes and user manuals for detailed programming instructions.

9. Handling and Storage:

   • Handle the device with care to avoid electrostatic discharge (ESD).
   • Store the device in a dry environment to prevent moisture damage.
