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.

Flash emulation of ROM versions
– ROM versions 3S12HZ256, 3S12HZ192, 3S12HZ128 and 3S12HN128 should use the
9S12HZ256 for Flash emulation.
– ROM versions 3S12HZ64, 3S12HN64, 3S12HZ32 and 3S12HN32 should use the 9S12HZ64
for Flash emulation.
Pin out explanations:
– A/D is the number of A/D channels.
– PWM is the number of TIM channels.
– LCD denotes the number of front planes times the number of back planes.
– Motor denotes the number of high current drive pins / number of stepper motors which can be
driven
– SSD denotes whether this device features a Stepper Stall Detection Circuit
– Versions with one SCI will use SCI0
– Versions with one CAN will use CAN0
– I/O is the sum of ports capable to act as digital input or output.
