UDP UPPI Card UG UDP UPPI CARD USERS GUIDE 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. Figure 1.

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. 2.1.
