The MC9S12HZ256CPV microcontroller units (MCU) are 16-bit devices composed of standard on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), up to 256K bytes of Flash EEPROM or ROM, up to 12K bytes of RAM, 2K bytes of EEPROM, 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 (ATD), a six-channel pulse width modulator (PWM), and two CAN 2.0 A, B software compatible modules (MSCAN). In addition, they feature a 32x4 liquid crystal display (LCD) controller/driver, a pulse width modulator motor controller (MC) consisting of 16 high current outputs suited to drive up to four stepper motors, and four stepper stall detectors (SSD) to simultaneously calibrate the pointer position of each motor. System resource mapping, clock generation,interrupt control, and external bus interfacing are managed by the HCS12 Core. The MC9S12HZ256CPV have 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, 8 general-purpose I/O pins are available with interrupt and wake-up capability from stop or wait mode.
