Product details
Overview
ST7MDT25-DVP3 from STMicroelectronics is a third-generation low-cost real-time emulator for ST7 microcontrollers, supporting in-circuit debugging (ICD) and in-circuit programming (ICP) via 10-pin ICC interface, with emulation at 3.3 V or 5 V and programmable clock up to 16 MHz, used during firmware development for industrial control and automotive body electronics.
For engineers reviewing the ST7MDT25-DVP3 datasheet, ST7MDT25-DVP3 pinout, ST7MDT25-DVP3 application, or ST7MDT25-DVP3 equivalent, this page details its modular architecture (Main Emulation Board + Target Emulation Board), ICC cable compatibility, parallel/USB host interface, and integration with free STVD7/STVP7 software tools.
Technical Context
The ST7MDT25-DVP3 implements a modular emulation system comprising a Main Emulation Board (MEB) and ST7-family-specific Target Emulation Board (TEB), enabling both full-cycle emulation (replacing target ST7) and ICC-mode debugging/programming on live application boards. It supports real-time trace with 512-record depth and conditional breakpoints up to 64 KB.
Host connectivity is provided via parallel port or USB interface; ICC communication uses a standardized 10-pin header with defined signal mapping (VDD, VSS, RESET, CLK, DATA). The system operates at either 3.3 V or 5 V, matching common ST7 supply domains, and delivers programmable emulation clock up to 16 MHz for timing-accurate execution analysis.

FAQ
What software is required to use the ST7MDT25-DVP3?
ST7MDT25-DVP3 requires STMicroelectronics' free ST7 Visual Develop (STVD7) IDE for debugging and ST7 Visual Programmer (STVP7) for flash programming. Both run on Windows and communicate with the emulator via parallel or USB interface. No license fees or subscriptions are needed.
Does the ST7MDT25-DVP3 include adapters for my ST7 package?
No - ST7MDT25-DVP3 includes only the Main Emulation Board and ST7MDT25-specific Target Emulation Board. Package-specific adapters (e.g., SO8, PDIP28, QFP44) must be ordered separately as ST7MDT25-xxx/DVP kits, each containing sockets and interface cables matching the target device footprint.
Can the ST7MDT25-DVP3 emulate all ST7 microcontrollers?
No - it emulates only ST7 devices in the MDT25 family (e.g., ST7MDT25, ST7MDT251, ST7MDT252). To emulate other ST7 families (e.g., ST7LITE, ST7FLITE), a different Target Emulation Board (e.g., ST7xxxx-TEB/DVP) must be purchased and installed on the same Main Emulation Board.
Is USB connectivity plug-and-play on modern Windows systems?
USB connectivity requires STMicroelectronics' signed USB driver, included with STVD7/STVP7 installers. On Windows 10/11, manual driver installation is needed; the emulator does not appear as a standard CDC device and will not function without this driver loaded prior to first use.
