10. Motherboard
The Si1000 and Si1010 Development Kit includes a motherboard that enables evaluation and preliminary software
development. Numerous input/output (I/O) connections are provided to facilitate prototyping using the target board.
Refer to Figure 8 for the locations of the various I/O connectors. Figure 10 on page 14 shows the factory default
shorting block positions.
P1
Expansion connector (96-pin)
P2
Power connector (accepts input from 7 to 15 VDC unregulated power adapter)
P3
USB connector (connects to PC for serial communication)
J1
Enable/Disable VBAT Power LED
J2, J3, J4
Port I/O headers (provide access to Port I/O pins)
J5
Enable/Disable VDD/DC+ Power LED
J6
Provides an easily accessible ground clip
J7
Connects pin P0.7 (IREF0 Output) to resistor R14 and capacitor C19
J8
Connects P0.2 and P0.3 to switches and P1.5 and P1.6 to LEDs
J9
DEBUG connector for Debug Adapter interface
J10, J11
Selects the power supply source (Wall Power, AAA Battery, or Coin Cell)
J12
Connects Port I/O to UART0 interface
J13
Connects external VREF capacitor to the P0.0/VREF
J14
Connects the PCB ground plane to P0.1/AGND
J15
Connects negative potentiometer (R14) terminal to pin P1.4 or to GND
J16
Connects the potentiometer (R14) wiper to P0.6/CNVSTR
J17
Creates an open in the power supply path to allow supply current measurement
J18,J19
Connects signals on P1 to the appropriate GPIO. Short J18 for Si100x and J19 for Si101x.
J20
Connects signals on J18/J19 to the EEPROM accessible through P4.
H1
Analog I/O terminal block
H2
Provides terminal block access to the input and output nodes of J17
SW4
Switches the device between One-Cell (0.9–1.8 V supply) or Two-Cell (1.8–3.6 V) mode
SW5
Turns power to the MCU on or off
