5 STLINK-V3MINIE functional description
5.1 STLINK-V3MINIE overview
STLINK-V3MINIE is a stand-alone debugging and programming tiny probe for the STM32 microcontrollers. The
product supports many functions and protocols for debugging, programming, or communicating with one or
several targets.
The 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-V3MINIE frequency selection
The STLINK-V3MINIE tiny probe runs internally at three different frequencies:
•
High-performance frequency
• Standard frequency, compromising between performance and consumption
• Low-consumption frequency
By default, STLINK-V3MINIE starts at a 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-V3MINIE tiny probe supports a high
‑
performance configuration for STM32 microcontrollers. The
working voltage range goes from 1.65 to 3.6 V. The protocols and functions supported are:
•
SWD with SWO (Up to 24 MHz)
• JTAG (Up to 21 MHz)
• VCP (From 736 bps to 16 Mbps)
A double
‑
row, 14
‑
pin (2 × 7) 1.27 mm pitch male STDC14 connector is located in STLINK-V3MINIE for connection
to the application target. An STDC14 to STDC14 flat cable is included in the packaging.
5.4 Hardware layout
The STLINK-V3MINIE tiny probe is designed around the STM32F723 microcontroller. Figure 2 shows STLINK-
V3MINIE. Figure 3 and Figure 4 show MB1762 top and bottom layouts, as MB1762 is the common board
reference for STLINK-V3MINIE.
