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
simultaneously 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.

NOTES:
1. Not recommended for new designs.
•
Flash emulation of ROM versions
– ROM versions 3S12HZ256 and 3S12HZ128 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 PWM channels.
– TIM 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.

Port A = 8, B = 4, E = 4 + 1 input only, K = 5, L = 4, M = 2, P = 4, S = 4, T = 8, U = 8, V = 8, AD = 8.
9 inputs provide Interrupt capability (AD = 8, XIRQ).
80 Pin Package for 9HZ64, 9HN64, 3HZ64, 3HN64, 3HZ32 and 3HN32 Versions:
Port A = 8, B = 4, E = 4 + 1 input only, K = 5, M = 2, P = 4, S = 4, T = 4, U = 8, V = 8, AD = 7.
8 inputs provide Interrupt capability (AD = 7, XIRQ).

Compatibility Considerations
– For 9S12H256 and 9S12H128, pins associated with motors 0 and 5 should be left unconnected
to ensure compatibility with versions featuring 4 motors. The “Z” versions have only four
motors, 0 to 3, which correspond to motors 1 to 4 on 9S12H256 and 9S12H128.

Function 1: Pseudo-open-drain communication pin for the
background debug function.
Function 2: In MCU expanded modes of operation when instruction tagging is on, an input low on this pin during the falling
edge of E-clock tags the high half of the instruction word being
read into the instruction queue.
Function 3: At the rising edge during reset, the state of this pin
is latched to the MODC bit to set the MCU operating mode.

Function 1: Port B general purpose input or output pins.
Function 2: LCD frontplane segment driver output pin.
Function 3: In MCU expanded modes of operation, these pins

NOACC
Function 1: Port E general purpose input or output pin
Function 2: LCD frontplane segment driver output pin
Function 3: The XCLKS signal selects between an external
clock or oscillator configuration during reset. This pin should
be at a logic high during reset if an external clock is used on
the EXTAL input pin. This pin should be at a logic low during
reset if an oscillator circuit is configured on EXTAL and XTAL.
Since this pin is an input with a pull-down device during reset,
if the pin is left floating, the default configuration is an
oscillator circuit on EXTAL and XTAL.
Function 4: During MCU expanded modes of operation, the
NOACC signal, when enabled, is used to indicate that the
current bus cycle is an unused or “free” cycle. This signal will
assert when the CPU is not using the bus.
