16-bit Microcontroller HCS12H
Family
Introduction
Designed for automotive instrumentation applications, all members of the MCS12H-Family of
microcontroller units (MCU) are composed of standard on-chip peripherals including a 16-bit central
processing unit (CPU12), up to 256K bytes of Flash EEPROM or ROM, up to 12K bytes of RAM, up to 4K
bytes of EEPROM on Flash parts, one or two asynchronous serial communications interfaces (SCI), a
serial peripheral interface (SPI), an IIC-bus interface (IIC), an 8-channel 16-bit timer (TIM), a 16-channel,
10-bit analog-to-digital converter (ADC), up to six-channel pulse width modulator (PWM), and up to two
CAN 2.0 A, B software compatible modules. In addition, they feature a 32x4 liquid crystal display (LCD)
controller/driver and a motor pulse width modulator (MC) 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
simulataneously calibrate the pointer reset position of each motor. The MCS12H-Family has full 16-bit
data paths throughout. The inclusion of a PLL circuit allows power consumption and performance to be
adjusted to suit operational requirements. 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.
