Introduction

STR71xF

6/74

individual control bit to optimize power usage by turning off peripherals any time they are not

required.

Voltage Regulators

The STR710 requires an external 3.0-3.6V power supply. There are two internal Voltage

Regulators for generating the 1.8V power supply for the core and peripherals. The main VR

is switched off during low power operation.

Low Voltage Detectors

Each voltage regulator has an embedded LVD that monitors the internal 1.8V supply. If the

regulated voltage drops below a certain threshold, the LVD will reset the STR710. This

enhances the security of the system by preventing the MCU from going into an

unpredictable state.

An external reset circuit must be used to provide the RESET at V33 power-up. It is not

sufficient to rely on the RESET generated by the LVD in this case. This is because LVD

operation is guaranteed only when V33 is within the specification.

On-Chip Peripherals

CAN Interface (STR710 and STR712)

The CAN module is compliant with the CAN specification V2.0 part B (active). The bit rate

can be programmed up to 1 MBaud.

USB Interface (STR710 and STR711)

The full-speed USB interface is USB V2.0 compliant and provides up to 16 bidirectional/32

unidirectional endpoints, up to 12 Mb/s (full-speed), support for bulk transfer, isochronous

transfers and USB Suspend/Resume functions.

Standard Timers

Each of the four timers have a 16-bit free-running counter with 7-bit prescaler

Three timers each provide up to two input capture/output compare functions, a pulse

counter function, and a PWM channel with selectable frequency.

The fourth timer is not connected to the I/O ports. It can be used by the application software

for general timing functions.

Realtime Clock (RTC)

The RTC provides a set of continuously running counters driven by the 32 kHz external

crystal. The RTC can be used as a general timebase or clock/calendar/alarm function.

When the STR710 is in Standby mode the RTC can be kept running, powered by the low

power voltage regulator and driven by the 32 kHz external crystal.

UARTs

The 4 UARTs allow full duplex, asynchronous, communications with external devices with

independently programmable TX and RX baud rates up to 1.25 Mb/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.
