STR71xF - INTRODUCTION
5/49
Standard Timers
Each of the four timers have a 16-bit free-running counter with 7-bit prescaler, up to two input
capture/output compare functions, a pulse counter function, and a PWM channel with
selectable frequency.
Realtime Clock (RTC)
The RTC provides a set of continuously running counters driven by a low power 32kHz
internal oscillator. The RTC can be used as a general timebase or clock/calendar/alarm
function. When the
STR71xF
is in Standby mode the RTC can be kept running, powered by
the low power voltage regulator and driven by the 32kHz internal oscillator.
UARTs
The 4 UARTs allow full duplex, asynchronous, communications with external devices with
independently programmable TX and RX baud rates up to 625 kb/s.
Smart Card Interface
UART1 is configurable to function either as a general purpose UART or as an asynchronous
Smart Card interface as defined by ISO 7816-3. It includes Smart Card clock generation and
provides support features for synchronous cards.
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.

mode (400 kHz) and 7 or 10-bit addressing modes.
One I

C Interface is multiplexed with one SPI, so either 2xSPI+1x I

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 continuous conversion modes. Resolution is 12-bit with a sample rate of 0.5 kHz (1 kHz in
single channel mode). The input voltage range is 0-2.5V.
