4 / 22 page STR73xF Data Brief 4/22 Low Voltage Detectors The voltage regulator and Flash modules each have an embedded LVD that monitors the internal 1.8V supply. If the voltage drops below a certain threshold, the LVD will reset the STR73xF. Note: An external power-on reset must be provided ensure the microcontroller starts-up correctly. On-Chip Peripherals CAN Interfaces The three CAN modules are compliant with the CAN specification V2.0 part B (active). The bit rate can be programmed up to 1 MBaud. These are not available in the STR735 and STR736. DMA 4 DMA controllers, each with 4 data streams manage memory to memory, peripheral to memory and memory to peripheral transfers. The DMA requests are connected to TIM timers, BSPI0, BSPI1, BSPI2 and ADC. One of the streams can be configured to be triggered by a software request, independently from any peripheral activity. 16-bit Timers (TIM) Each of the ten timers (six in 100-pin devices) 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. This provides a total of 16 independent PWMs (12 in 100-pin devices) when added with the PWM modules (see next paragraph). PWM Modules (PWM) The six 16-bit PWM modules have independently programmable periods and duty-cycles, with 5+3 bit prescaler factor. Timebase Timers (TB) The three 16-bit Timebase Timers with 8-bit prescaler for general purpose time triggering operations. Realtime Clock (RTC) The RTC provides a set of continuously running counters driven by separate clock signal derived from the main oscillator. The RTC can be used as a general timebase or 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 625K baud. |
