1．Introduction
The STEP-MXO2 development board presents a robust, portable and easy-to-learn hardware
design platform built around the Lattice MachXO2 4000HC FPGA.
This board currently features the MachXO2-4000HC FPGA which offers embedded Flash
technology for instanton, non-volatile operation in a single chip. Numerous system functions
are included, such as two PLLs and 10 Kbits of embedded RAM plus hardened
implementations of I2C, and user Flash memory.
The STEP MXO2 FPGA development board includes hardware such as on-board JTAG
Programmer, 7-Segment Displays, LEDs, GPIOs and much more. By leveraging all of these
capabilities, the STEP MXO2 FPGA development board is the perfect solution for learning
FPGA, evaluating and prototyping the true potential of the MXO2 FPGA.
