MC9S12H256 General Description
The MC9S12H256 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), 256K bytes of Flash EEPROM, 12K bytes of RAM, 4K 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).
The MC9S12H128 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), 128K bytes of Flash EEPROM, 6K bytes of RAM, 2K bytes of EEPROM, one asynchronous serial communications interface (SCI), a serial peripheral interface (SPI), an IIC-bus interface (IIC), an 8-channel 16-bit timer (TIM), a 8-channel, 10-bit analog-to-digital converter (ATD), a two-channel pulse width modulator (PWM), and two CAN 2.0 A, B software compatible modules (MSCAN).
In addition, it features a 32x4 liquid crystal display (LCD) controller/driver and a motor pulse width modulator (MC) consisting of 24 high current outputs suited to drive up to 6 stepper motors. System resource mapping, clock generation, interrupt control, and bus interfacing are managed by the HCS12 Core.
The MC9S12H256 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, 12 general purpose I/O pins are available with interrupt and wake-up capability from STOP or WAIT mode.

1. Beyond absolute maximum ratings device might be damaged.
2. The device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply. The absolute maximum ratings apply when the device is powered from an external source.
3. All digital I/O pins are internally clamped to VSSX1/2 and VDDX1/2, VSSM and VDDM or VSSA and VDDA.
4. Ports PU, PV, PW are internally clamped to VSSM and VDDM.
