1. Introduction
This guide describes the ASC Bridge Board, an interface board that connects up to three ASC Breakout Boards to
either the MachXO3™-9400 Development Board or the ECP5™Versa Development board for rapid prototyping
and testing platform and hardware management applications. Throughout this document, the phrase ASC
Breakout Board refers to a Platform Manager 2 evaluation board that is known by several names. The silkscreen
on the board itself is PM2 ASC EVAL BOARD, the ordering part number is LPTM-ASC-B-EVN, and on the Lattice web
site, the product name is L-ASC10 Breakout Board. The ASC Bridge Board does not contain any programmable
logic nor does it have a USB connector for power or programming. The ASC Bridge Board is primarily an
interconnect between the ASC Breakout Boards and either the MachXO3-9400 Development Board or the ECP5
Versa Development Board.
The content of this user guide includes descriptions of on-board jumper settings, tables detailing the inter-board
connections, a complete set of schematics and the bill of materials for the ASC Bridge Board.
Complete descriptions of the MachXO3 FPGA, ECP5 FPGA, and L-ASC10 devices are found in the MachXO3 Family Data
Sheet (FPGA-DS-02032), ECP5 and ECP5-5G Family Data Sheet (FPGA-DS-02012), and L-ASC10 Data Sheet (FPGA-DS-
02038).
For full descriptions of the MachXO3-9400 Development Board, ECP5 Versa Development Board and L-ASC10 Breakout
Board, see the MachXO3-9400 Development Board User Guide (FPGA-EB-02004), ECP5 Versa Development Board User
Guide (FPGA-EB-02021), and ASC Breakout Board User Guide (FPGA-EB-02023).

3. Setting Up the Board
To set up the board:
Attach four of the included nylon standoffs to the ASC Bridge Board (only one standoff is needed at the narrow
edge of the board).
Attach two of the included nylon standoffs to the outside edge of each ASC Breakout Board.
Connect the ASC Bridge Board using the Versa connectors (J2 and J3) to either the MachXO3-9400 Development
Board or the ECP5 Versa Development Board.
Connect the ASC Breakout Board(s) using J6, J7 and J13 as shown in Figure 2.1. The number of ASC Breakout Boards
to install is based on the design requirement.
Slide SW3 to the MachXO3 position if the MachXO3-9400 Development Board is connected.
Note: SW3 can also remain in the MachXO3 position for new ECP5 designs as long as the I2C pins are mapped
according to Table D.4 in Appendix D. SW3 only needs to be in the ECP5 position to support a legacy demo design.
SW3 swaps the SDA and SCL signals on the ASC Bridge Board (see Figure A.2 in Appendix A).
4. Applying Power to the Board
The 3.3 V system power is supplied by either the MachXO3-9400 Development Board or the ECP5 Versa Development
Board. Depending on your design requirement, the 5 V and 12 V power can be applied through the ASC Breakout Board
(after the Hot Swap and/or Trim circuits have been populated).
Refer to the either the MachXO3-9400 Development Board User Guide (FPGA-EB-02004) or the ECP5 Versa
Development Board User Guide (FPGA-EB-02021), and ASC Breakout Board User Guide (FPGA-EB-02023) on how to
connect these power supplies. When using the 5 V and 12 V power supply, only one ASC Breakout Board is needed to
connect to the power source. By shorting jumpers J8, J9, and J14, the 5 V supply connects to the other ASC Breakout
Boards. Jumpers J4, J5, and J12 will do the same for the 12 V supply.
Note: The ASC Breakout Board may be populated with user supplied 3.3 V voltage regulator (DCDC5). When setting up
the platform, be sure that only one board is supplying the 3.3 V power to prevent power supply contention.
5. System Clock
The 8 MHz system source clock comes from the ASC0 device. When using the MachXO3-9400 Development Board, no
clock jumpers need to be installed on the ASC Bridge Board; the ASC0 device is located on the MachXO3-9400
Development Board and the clock signal is hard-wired to the MachXO3.
When using the ECP5 Versa Development board, the ASC0 device can be plugged-in to any of the ASC connectors.
Shorting one of the jumpers, J10, J11, J15, enables the ASC0 ASCCLK to connect to ECP5 device. It is recommended to
connect only one jumper.

7. J2 and J3 Female Header
J2 and J3 are 40-pin female headers that connect the signals from either the MachXO3-9400 Development Board or the
ECP5 Versa Development Board to the ASC Bridge Board. The female header carries both signal and power. The
connections for J2 and J3 are listed in Appendix C and Appendix D.
Note: The connections referenced in this document refer to the LFE5UM-45F-8BG381C device.
8. J6, J7 and J13 D-SUB25 Connector
The L-ASC10 Evaluation Board is connected to the ASC Bridge Board through D-SUB 25-pin connectors. These
connectors carry both signal and power.

when the jumper in on the 2-3 location. A hold-up capacitor is inserted in parallel with the fan to guarantee proper
under speed detection. The ASC Bridge Board has a set of pre-populated capacitors connected through jumper J18. For
fan PWM frequency less than 10 kHz, connect J18 to the 1-2 location. Connect J18 to the 2-3 location for fan PWM
frequency between 10 kHz to 26.7 kHz. If the fan PWM frequency is greater than 40 kHz, leave J18 unconnected. For
more information about fan control, please refer to TN1278, Temperature Monitoring and Fan Control with Platform
