Programmability
smartBASIC
On-board programming language similar to BASIC.
smartBASIC application
download
(1) Via UART.
(2) Via 2-Wire SWD Programming/Debug Interface
Control Protocols
Any
User defined via smartBASIC
Operating Modes
Self-contained Run mode
Selected by nAutoRun pin status:
nAutoRun = LOW (0V): Then runs $autorun$
(smartBASIC application script) if it exists.
Interactive / development
mode
nAutoRun = HIGH (VCC): Then runs via at+run (and
“file name” of smartBASIC application script).

Internal DCDC converter (Note 5)
1.8V – 2.1V
Internal LDO
DCDC switched on if VCC >2.1V at power-up
