Software Requirements
You should install the following software before you begin developing designs for the evaluation board:
• Lattice Diamond™ 1.2 or higher
• ispVM™ System 17.9.1 or higher
Control SoC Demonstration Design
The Control System-on-Chip (SoC) demonstration illustrates the use of the LatticeMico8 microcontroller, peripher-
als, and firmware integrated to provide system control features such as power supply sequencing, voltage monitor-
ing, data logging to nonvolatile memory, I/O control, embedded block RAM utilization, UART communication and
PLL status monitoring.
• The Power Manager II device sequences the power-up of voltage rails on the board and performs reset distribu-
• LatticeMico8 executable program initializes the peripherals that are embedded in the SoC design. During initial-
• Users interact with LatticeMico8 and the board through the HyperTerminal of a PC.

Power management is handled in two phases by the MachXO2 Control Evaluation Board system:
1. Power On – After power is supplied to the board and the 3.3V rail is stable, the POWR1014A sequences four
2. Post Power On – During the second phase of power management, the board’s “condition” is monitored. Power
MachXO2 Function – After the reset is de-asserted, LatticeMico8 initializes the peripherals embedded in the
MachXO2 device and uploads the user menu onto the HyperTerminal window of a PC.

(HVOUT) outputs and two demonstrate power rail enable of VCC_CORE and VCCP of the MachXO2 using
digital outputs. Next, the POWR1014A asserts the MachXO2 reset. Finally, the POWR1014A enters a supply
