STLINK-V3MODS and STLINK-V3MINI functional
description
5.1 STLINK-V3MODS
and
STLINK-V3MINI overview
STLINK-V3MODS and STLINK-V3MINI are stand-alone debugging and programming tiny
probes for STM32 microcontrollers. These products support many functions and protocols
for debugging, programming, or communicating with one or several targets.
These modules are fully powered by the PC. If the COM LED blinks red, refer to the
technical note
Overview of ST-LINK derivatives
(TN1235) for details.
5.2 STLINK-V3MODS
and
STLINK-V3MINI frequency selection
The STLINK-V3MODS and STLINK-V3MINI run internally at three different frequencies:
•
high-performance frequency
•
standard frequency, compromising between performance and consumption
•
low-consumption frequency
By default, the STLINK-V3MODS and STLINK-V3MINI start in high-performance frequency.
It is the responsibility of the toolchain provider to propose or not the frequency selection at
the user level.
5.3 High-performance
modules
The STLINK-V3MODS and STLINK-V3MINI support high-performance configuration for
STM32 microcontrollers. The working voltage range is from 3.0 to 3.6 V.
The protocols and functions supported are:
•
SWD (up to 24 MHz) with SWO (up to 16 MHz)
•
JTAG (up to 21 MHz)
•
VCP (from 732 bps to 16 Mbps)
