S9S12HZ256J3CAL

16Bit MCU, S12 core, 256KB Flash, 50MHz, -40/+85℃, Automotive Qualified, QFP 112

The MC9S12HZ256 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 MC9S12HZ256 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.
