Electrical Characteristics
Overview
The MC1231A consists of two 68 pin PLCC's both fabricated in CMOS.
The Peripheral Input/Output IC (I/O chip) is responsible for interfacing
to the host processor and to the position input encoders. The Command
Processor IC (CP chip) is responsible for all host command, trajectory,
servo, and commutation computations, as well as for outputting the
PWMand DAC signals.
The following figure shows a typical systemblock diagram along with
the pin connections between the I/O chip and the CP chip.

The CP and I/O chips function together as one integrated motion
processor. The major components connected to the chip set are the
Encoder (2, or 1 axes), (optionally) the motor Hall-sensors (2 or 1 axes),
the motor amplifier (2, or 1 axes), and the host processor.
The encoder signals are input to the I/O chip in quadrature format. Two
signals encode the position, and an optional index signal contains a
once-per-rotation locating signal.
Hall sensors may be connected to the chipset to provide phase
initialization information, although this is not required. Three Hall sensor
signals are input per axis.
The chipset's motor output signals are connected to the motor amplifier.
Two types of output are provided; PWM(pulse width modulation), and
DAC-compatible signals used with an external DAC (digital to analog
converter). Because the output signals are commutated, more than one
motor output signal will be output per axis. See Theory of Operations
section on sinusoidal motor commutation for details.
The host processor is interfaced via an 8-bit bi-directional bus and
various control signals. Host communication is coordinated by a
ready/busy signal, which indicates when communication is allowed.
Interconnections between the two chips consist of a data bus and
various control and synchronization signals. The following table
summarizes the signals that must be interconnected for the chipset to
function properly. For each listed signal the I/O chip pin on the left side
of the table is directly connected to the pin to the right.
