STM32F103xx

Description

Universal serial bus (USB)

The STM32F103xx performance line embeds a USB device peripheral compatible with the

USB Full-speed 12 Mbs. The USB interface implements a full speed (12 Mbit/s) function

interface. It has software configurable endpoint setting and suspend/resume support. The

dedicated 48 MHz clock source is generated from the internal main PLL.

GPIOs (general-purpose inputs/outputs)

Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as

input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the

GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current-

capable.

The I/Os alternate function configuration can be locked if needed following a specific

sequence in order to avoid spurious writing to the I/Os registers.

ADC (analog to digital converter)

Two 12-bit Analog to Digital Converters are embedded into STM32F103xx performance line

devices and each ADC shares up to 16 external channels, performing conversions in single-

shot or scan modes. In scan mode, automatic conversion is performed on a selected group

of analog inputs.

Additional logic functions embedded in the ADC interface allow:

● Simultaneous sample and hold

● Interleaved sample and hold

● Single shunt

The ADC can be served by the DMA controller.

An analog watchdog feature allows very precise monitoring of the converted voltage of one,

some or all selected channels. An interrupt is generated when the converted voltage is

outside the programmed thresholds.

The events generated by the standard timers (TIMx) and the Advanced Control timer (TIM1)

can be internally connected to the ADC start trigger, injection trigger, and DMA trigger

respectively, to allow the application to synchronize A/D conversion and timers.

Temperature sensor

The temperature sensor has to generate a linear voltage with any variation in temperature.

The conversion range is between 2 V < VDDA < 3.6 V. The temperature sensor is internally

connected to the ADC_IN16 input channel which is used to convert the sensor output

voltage into a digital value.

Serial wire JTAG debug port (SWJ-DP)

The ARM SWJ-DP Interface is embedded. and is a combined JTAG and serial wire debug

port that enables either a serial wire debug or a JTAG probe to be connected to the target.

The JTAG TMS and TCK pins are shared respectively with SWDIO and SWCLK and a

specific sequence on the TMS pin is used to switch between JTAG-DP and SW-DP.
