Electrical Characteristics
Overview
The MC1401A-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, profile and
servo computations, as well as for outputting the PWM and DAC
signals.
The following figure shows a typical system block diagram, along with
the pin connections between the I/O chip and the CP chip.

Processor
The CP and I/O chips function together as one integrated motion
processor. The major components connected to the chip set are the
Encoder (4, 2, or 1 axes), the motor amplifier (4, 2, or 1 axes), and the
host processor.
For the standard MC1401A parts (non '-P' parts), the encoder signals
are input to the I/O chip in quadrature format. For the '-P' parts the
encoder information is input directly into the CP chip, via an 8 bit data
bus and various control signals.
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).
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.
