STR71xF
Introduction
Buffered Serial Peripheral Interfaces (BSPI)
Each of the two SPIs allow full duplex, synchronous communications with external devices,
master or slave communication at up to 5.5Mb/s in Master mode and 4 Mb/s in Slave mode.
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.
One I²C Interface is multiplexed with one SPI, so either 2xSPI+1x I²C or 1xSPI+2x I²C may
be used at a time.
HDLC interface
The High Level Data Link Controller (HDLC) unit supports full duplex operation and NRZ,
NRZI, FM0 or MANCHESTER protocols. It has an internal 8-bit baud rate generator.
A/D Converter
The Analog to Digital Converter, converts in single channel or up to 4 channels in single-
shot or round robin mode. Resolution is 12-bit with a sampling frequency of up to 1 kHz. The
input voltage range is 0-2.5V.
Watchdog
The 16-bit Watchdog Timer protects the application against hardware or software failures
and ensures recovery by generating a reset.
I/O Ports
The 48 I/O ports are programmable as Inputs or Outputs.
External Interrupts
Up to 14 external interrupts are available for application use or to wake-up the application
from STOP mode.
