Evaluation Board User Guide 1. Introduction This user guide describes how to start using the MachXO2 and MachXO3 Starter Kits, an easy-to-use platform for evaluating and designing with the Mach XO2 and MachXO3 ultra-low-density FPGA. Along with the board and accessories, this kit includes a pre-loaded demonstration design.
Overview The Starter Kit is a complete development platform for the MachXO2 and MachXO3 FPGAs. The board includes a prototyping area, a USB program/power port, an LED array, switches, and header landings with electrical connections to most of the FPGA’s programmable I/O, power, and configuration pins. The board is powered by the PC’s USB port or optionally with external power.
Upon power-up, the pre-programmed demonstration design automatically loads and drives the LED array in a 1-hertz pattern. The program shows a clock divider driven either by the MachXO2/MachXO3 internal oscillator or the external FTDI clock chip. The divider modules (heartbeat.v and kitcar.v) are clocked at the default frequency of 12 MHz which divides the clock to cycle the LED display approximately once per second.
Serial Data C9:SDA Serial Clock A9:SCL LEDs A blue LED (D1) is used to indicate USB 5V power. Eight red LEDs are driven by I/O pins of the MachXO2/MachXO3 device. Table 7.11. Power and User LEDs Reference Item Description Reference Designators...
Measuring Bank and Core Power Test points (TP1, TP2) provide access to power supplies of the MachXO2/MachXO3 FPGA. Inline 1 Ω resistors: R31 (VCCIO0, +3.3 V, Bank 0), R25 (VCCIO1, +3.3 V, Bank 1), R37 (VCCIO2, +3.3 V, Bank 2), R32 (VCCIO3, +3.3 V, Bank 3), R26 (VCCIO4, +3.3 V, Bank 4), R38 (VCCIO5, +3.3 V, Bank 5), R24 (VCC core, +1.2 V) can be used to measure current for the...
