STR73xFxx
clock/calendar/alarm function. When the STR73xF is in LPWFI mode the RTC keeps
running, powered by the low power voltage regulator.
UARTs
The 4 UARTs allow full duplex, asynchronous, communications with external devices with
independently programmable TX and RX baud rates up to 625 Kbaud.
Buffered serial peripheral interfaces (BSPI)
Each of the three BSPIs allow full duplex, synchronous communications with external
devices, master or slave communication at up to 6 Mb/s in master mode and up to 4.5 Mb/s
in slave mode (@36 MHz system clock).

I
A/D converter
The 10-bit analog to digital converter, converts up to 16 channels in single-shot or
continuous conversion modes (12 channels in 100-pin devices). The minimum conversion
time is 3 µs.
Watchdog
The 16-bit watchdog timer protects the application against hardware or software failures and
ensures recovery by generating a reset.
I/O ports
Up to 112 I/O ports (72 in 100-pin devices) are programmable as general purpose
input/output or alternate function.
External interrupts and wake-up lines
16 external interrupts lines are available for application use. In addition, up to 32 external
Wake-up lines (18 in 100-pin devices) can be used as general purpose interrupts or to
wake-up the application from STOP mode.
