1. Introduction
The UPPI-series evaluation cards are the engine of an MCU-based system, containing an MCU, optional radio,
and minimal support circuitry.
These cards are designed around either a C8051F96xMCU or a Si102x/3x Wireless MCU. Only placement-critical
items, such as bypass capacitors, crystals, dc-dc inductor, and RF front end circuitry are included. All other circuits
reside on the hosting platform.
These cards are compatible with Silicon Labs Unified Development Platform MCU cards (UDP-F960-MCU series).
They may also be used as prototyping modules, as they fit on a 2 mm-center prototyping board.

2. Description
The UPPI cards contain the MCU device and a minimal number of supporting components. Most of the core device
pins are connected directly to headers, allowing signal mapping to be defined by the host board, typically a UDP
MCU card. (See “2.3. Compatibility” for more information.)
Each board design varies in schematic and features. Refer to the board design files available from
www.silabs.com
for specifics.
