7. MachXO2 and MachXO3 Starter Kits
This section describes the features of the MachXO2 and MachXO3 Starter Kits in detail.
Subsystems
This section describes the principal subsystems for the Starter Kit in alphabetical order.
Clock Sources
Clock sources for the LED demonstration designs originate from the MachXO2/MachXO3 on-chip oscillator or the 12
MHz crystal X1. You may use an expansion header landing to drive a FPGA input with an external clock source.
Expansion Header Landings
The expansion header landings provide access to user GPIOs, primary inputs, clocks, and VCCO pins of the
MachXO2/MachXO3 device. The remaining pins serve as power supplies for external connections. Each landing is
configured as one 2 x 20 100 mil.
