STR73xFxx

Overview

7/52

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).

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 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.
