Product details
Overview
ST7MDT20-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, operating at 3.3 V or 5 V, with programmable clock up to 16 MHz, and 512-record trace capability. It enables full application development on target boards without removing the ST7 device.
For engineers reviewing the ST7MDT20-DVP3 datasheet, ST7MDT20-DVP3 pinout, ST7MDT20-DVP3 application, or ST7MDT20-DVP3 equivalent, this emulator is selected for ST7-based embedded firmware development requiring real-time debug visibility, breakpoint counting with conditions, external trigger support, and seamless integration with STVD7/STVP7 software tools.
Technical Context
The ST7MDT20-DVP3 implements a modular architecture comprising a Main Emulation Board and ST7-family-specific Target Emulation Board (TEB), enabling emulation or ICC configuration. It supports both parallel and USB host PC interfaces and delivers hardware-level trace filtering and output trigger generation.
In emulation mode, it replaces the target ST7MCU on the application board using socketed adapters; in ICC mode, it connects directly to the ST7's ICC pins (SWIM-compatible 5-wire interface) for non-intrusive debugging and programming without physical replacement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Emulation Mode | Replaces target ST7MCU on board using socket/adapters; requires no modification to target PCB layout. |
| ICC Mode | Connects via 10-pin ICC cable to SWIM interface on ST7; enables ICD/ICP without removing MCU. |
| Host Interface | Parallel port or USB (via optional adapter); provides bidirectional communication with STVD7/STVP7. |
| Trace Buffer | 512-record instruction trace with configurable filtering; captures execution flow for timing analysis. |
| Breakpoint Support | Up to 64 Kbytes of conditional breakpoints with counters; allows precise state-dependent halting. |
| Operating Voltage | 3.3 V or 5 V selectable; matches common ST7 supply domains without level-shifting circuitry. |

FAQ
Does ST7MDT20-DVP3 require additional hardware to debug an ST7 application?
Yes - it requires either a compatible Target Emulation Board (e.g., ST7MDT20-TEB/DVP) and package-specific adapter kit, or a 10-pin ICC connector installed on the target board. The main board alone does not connect directly to ST7 devices without these components.
Is ST7MDT20-DVP3 compatible with modern Windows operating systems?
Official ST support ended with Windows XP, but community drivers and virtual machine setups (e.g., Windows XP SP3 in VirtualBox) enable continued use with STVD7 and STVP7. No native Windows 10/11 driver is provided by STMicroelectronics.
Can ST7MDT20-DVP3 program flash memory on all ST7 variants?
It supports ICP for all ST7 devices with SWIM interface and standard ICC pinout (e.g., ST72xx, ST7Lxx, ST7FLxx). Devices lacking SWIM or using proprietary packaging may require custom adapter kits or are unsupported per ST's DVP3 documentation.
What software tools are mandatory for ST7MDT20-DVP3 operation?
ST7 Visual Develop (STVD7) and ST7 Visual Programmer (STVP7) are mandatory free tools from STMicroelectronics. They provide IDE functionality, source-level debugging, breakpoint management, and flash programming - no third-party IDE integration is supported.
