Digital I/O Extension for PMC & XMC FPGAs AXM-D

The Acromag AXM-D is a Digital I/O Extension for PMC & XMC FPGAs. These extensions plug into the front mezzanine on Acromag’s I/O Compatible FPGAs such as:

• ACR5264 LVDS and RS-485 Differential I/O

This module provides 30 differential I/O channels. Data direction, either input or output, on each channel is independently controlled. Eight of the channels support programmable change-of-state interrupts. 16 LVDS and 14 RS-485 differential I/O channels.

AXM-D01 LVTTL I/O

This module provides 64 LVTTL I/O channels for straight though I/O. custom modules are available for optional pull-ups, pull-downs, JTAG, and fused power for front I/O use.

AXM-D02 RS-485 Differential I/O

This module provides 30 differential I/O channels. Data direction, either input or output, on each channel is independently controlled. Eight of the channels support programmable change-of-state interrupts. JTAG option.

AXM-D03 CMOS and RS-485 Differential I/O

This module provides 16 CMOS and 22 RS-485 differential I/O channels. Data direction, either input or output, on each channel is independently controlled. Eight of the channels support programmable change-of-state interrupts.

AXM-DX03 CMOS and RS-485 Differential I/O

Same as AXM-D03 above except 16 CMOS and 24 RS-485 differential I/O channels. Provides a replacement for legacy PMC-DX503/2003 FPGA modules when used with PMC/XMC-SLX.

AXM-D04 LVDS

This module provides 30 channels of low voltage differential signalling with independently configured direction. Interrupts are programmable on eight of the channels for any bit change of state or level. JTAG option.

Features of the Digital I/O Extension for PMC & XMC FPGAs AXM-D include:

• Various modules allows users to select the Front I/O required for their application.
• Differential RS485/RS422 is configurable for input or output with independent direction control.
• Interface with 5V compliant input/output CMOS channels is configurable as input or output with independent direction control.
• Low voltage differential signalling is configurable for input or output with independent direction control.
• The EDK board provides the standard Xilinx JTAG interface to allow direct programming of the FPGA and an interface with ChipScope®.
• Example code provides interrupts that are software programmable for any bit Change-Of-State or level on 8 channels.
• Example Design – The example VHDL design, provided in the base board EDK, includes control of all I/O, and eight Change-Of-State interrupts.
• Operating temperature: -40 to 85°C
