Typical Application Circuit
4 Typical Application Circuit
A basic application circuit for the
EMB-Z2538PA
is shown in Image 15. The
EMB-Z2538PA
allows for a minimal number of external components (thus decreasing system costs).
In Image 15 a LED indicator (LED1) and a push button (SW1) are used to provide a minimal
user interface. The JTAG programming/debugging interface, generally speaking, will be
routed to a connector on the host board for in-circuit programming.
In addition, a simple supply section (based on a 3.3V LDO stabilizing the input voltage VIN)
and a simple reset circuitry are shown. In particular, the reset circuitry of Image 15 allows to
1. program the CC2538 MCU of the
EMB-Z2538PA
(thanks to the weak pull-up to VCC);
2. manually reset the CC2538 MCU, if needed (thanks to SW_RESET).
