UPMP-F960-EMIF
5.3. MCU Card Header Connections
The UPMP-F960-EMIF MCU card has four connectors with 100 pins each. These 400 pins are directly tied to the
UDP motherboard and I/O cards. These signals are named and designed to support a wide variety of features and
applications, and the UDP C8051F960/Si1020 MCU Card with EMIF card implements a subset of these
connections.
The MCU cards and I/O cards are designed so that a maximum number of functions are shared between each
card. This allows a particular type of I/O card to be shared amongst all MCU cards that connect to the same
signals.
The MCU card slot includes the following components:
J1
J2
J3
J4
The UPMP-F960-EMIF MCU card implements the signals described in Table 4, Table 5, Table 6, and Table 7 in the
Appendix.
5.4. Shorting Blocks: Factory Defaults
The UDP C8051F960/Si1020 MCU Card with EMIF comes from the factory with pre-installed shorting blocks on
several headers. Figure 7 shows the positions of the factory default shorting blocks.
Shorting blocks are installed on P2 to connect P0.4 to MCU_TX and P0.5 to MCU_RX.
