STR73xF Data Brief
Buffered Serial Peripheral Interfaces (BSPI)
Each of the three BSPIs allow full duplex, synchronous communications with external devices,
master or slave communication at up 6 Mb/s (@36 MHz System Clock).
I2C Interfaces
The two I2C Interfaces provide multi-master and slave functions, support normal and fast I2C
mode (400 kHz) and 7 or 10-bit addressing modes.
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 3us.
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.

DataShee
16 external interrupts lines are available for application use. In addition, up to 32 external
Wakeup lines (18 in 100-pin devices) can be used as general purpose interrupts or to
wake-up the application from STOP mode.
