FreeSoC2 Hookup Guide V14

Introduction

Note:

 This guide is for the latest version of the FreeSoC2, V14. If You have an older version (the version

number can be found on the back of the PCB), please refer to this tutorial.

The FreeSoc2 is SparkFun’s PSoC5LP development board features a full onboard debugger, support for 5V and
3.3V IO voltages, and a CY8C5888AXI-LP096 processor with 256kB of flash, 64kB of SRAM and 2kB of
EEPROM. The onboard oscillator can drive the processor at up to 80MHz, and the Cortex-M3 core provides
superior performance.

The real power of the PSoC5LP isn’t in the processor, however. Wrapped around the processor is a rich analog
and digital programmable fabric, which can be configured to provide many functions that would otherwise need to
be realized in code (lowering system performance) or external circuitry (adding cost and board size). In addition,
