6.0 Design guidelines
This section describes the software and hardware
considerations taken into account when designing the
target application.
For the design guidelines for the SC14CVMDECT base
station, please see [3].
6.1.1
The following connections are mandatory:
• Battery/supply terminal connected to ULE_VBAT
• Switched battery voltage VBATSW output (C11)
• VDD output (1.8V / D10) connected to VDDIO input
• GND connection to all Ground ports.
• High power drive GPIO supply VDDPA (E1)
• Minimum of 1uF capacitance connected to
(F6) and VBAT (B10).
connected to VBATuC (A9).
(A5).
connected to either VBATSW (3.3V I/O, C11) or
VDD output (1.8V I/O, D10).
CP_VOUT1 (B3).

6.1
Figure 8 shows a typical (simple) connection schematic
for the SC14WSMDATA module.
6.1.2
The most basic form of the programming and debug
interface is to make the JTAG and UART programming
interfaces available. Externally a USB to UART
converter board can be attached to connect it to the
PC. For the USB to UART reference design board see
[6]. Dialog uses connector types:
• PCB board: (male) Molex 0022292051
• Programming cable: (female) Molex 0022012055
The following connections are mandatory:
• VDD output (1.8V) D10 to pin 1 on header.
• JTAG output C10 to pin 2 on header.
• UTX output from module C8 to pin 3 on header.
(This output is used to detect I/O voltage levels.)
