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.
