PMAC PCI Lite Hardware Reference Manual
Introduction 1
INTRODUCTION
The PMAC PCI Lite is a member of the PMAC family of boards optimized for interface to traditional
servo drives with single analog inputs representing velocity or torque commands. Its software is capable
of eight axes of control, although it can have only four channels of on-board axis interface circuitry.
The PMAC PCI Lite is a full-sized PCI-bus expansion card. While capable of PCI bus communications,
with or without the optional dual-ported RAM, it does not need to be inserted into a PCI expansion slot.
Communications can be done through an RS232 or RS422 serial port. Standalone operation is possible.
The non-Turbo version of the PMAC PCI Lite board does not include ICs U140, U143 or U147.
Board Configuration
Base Version
The base version of the PMAC PCI Lite provides a 1-1/2-slot board with:
• 40 MHz DSP563xx CPU
• 128k x 24 zero-wait-state flash-backed SRAM
• 512k x 8 flash memory for f7irmware and user backup
• Latest released firmware version
• RS232/422 serial interface, 33Mhz PCI bus interface
• Four channels axis interface circuitry, each including:
• 16-bit +/-10V analog output
• 3-channel differential/single-ended encoder input
• Four input flags, two output flags
• Interface to external 16-bit serial ADC
• Display, control panel, mixed I/O, direct I/O interface ports
• Buffered expansion port
• Clock crystal with +/-100 ppm accuracy
• PID/notch/feedforward servo algorithms
• 1-year warranty from date of shipment
One manuals CD per set of one to four PMACs in shipment (cables, mounting plates, mating connectors
not included)
Option 2: Dual-Ported RAM
Dual-ported RAM provides a high-speed communications path for bus communications with the host
computer through a bank of shared memory. DPRAM is advised if more than about 100 data items per
second are to be passed between the controller and the host computer in either direction.
• Option 2 provides an 8k x 16 bank of on-board dual-ported RAM. The key component on the board
is U1.
Option 5xF: CPU Speed Options
The base PMAC PCI Lite version has a 40 MHz DSP563xx CPU. This is Option 5AF, which is provided
automatically, if no CPU speed option is specified.
• Option 5AF: 40 MHz DSP563xx CPU (80 MHz 56002 equivalent). This is the default CPU speed.
• Option 5CF: 80 MHz DSP563xx CPU (160 MHz 56002 equivalent).
• Option 5EF: 160 MHz DSP563xx CPU (320 MHz 56002 equivalent).
ICs U140, U143 and U147 are not
installed in the non-Turbo version of the
PMAC Lite-PCI board.
