Description

STM32F101x8, STM32F101xB

20/101

DocID13586 Rev 17

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.

2.3.23

ADC (analog to digital converter)

The 12-bit analog to digital converter has up to 16 external channels and performs

conversions in single-shot or scan modes. In scan mode, automatic conversion is performed

on a selected group of analog inputs.

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.

2.3.24

Temperature sensor

The temperature sensor has to generate a voltage that varies linearly with 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.

2.3.25

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.
