FUNCTIONAL DEVICE OPERATION
RESET AND WATCHDOG PINS, SOFTWARE WATCHDOG OPERATIONS
MCU FLASH PROGRAMMING CONFIGURATION
To download software into the application memory (MCU EEPROM or Flash) the SBC capabilities allows the VDD1 to be forced
by an external power supply to 5.0 V; the reset and WD outputs by external signal sources are forced to zero or 5.0 V, both
without damage. This allows, for example, supply of the complete application board by external power supply, applying the
correct signal to reset pins. No function of the SBC is operating.
Due to pass transistor from VDD1 to VSUP, supplying the device from VDD1 pin biases the VSUP pin. Therefore, VSUP should
not be forced to a value above 5.0 V. The Reset pin is periodically pulled low for RSTDUR time (3.4 ms typical) before being pulled
to VDD1 for 350 ms typical. During the time reset is low, the reset pin sinks 5.0 mA maximum (LPDW parameter).

PACKAGE AND THERMAL CONSIDERATION
The device is proposed in a standard surface mount SOIC28 package. In order to improve the thermal performances of the
SOIC28 package, eight pins are internally connected to the lead frame and are used for heat transfer to the printed circuit board.
Table 6 describes the SBC operation modes. Normal, Stand-by, and Stop Debug modes are entered through special
sequence described in the Debug mode paragraph.
