STMicroelectronics ST7MDT2-DVP2/US

Overview

ST7MDT2-DVP2 from STMicroelectronics is a development kit for ST7 microcontrollers, supporting emulation, in-system programming (ISP), and hardware debugging of SDIP42/56 and TQFP64-packaged MCUs including ST72334 and ST7511R9 families. It features parallel-port PC interface, dual ZIF sockets (SDIP56/SDIP42 and TQFP64), trace buffer recording, and compatibility with STVD7 debugger software.

For engineers reviewing the ST7MDT2-DVP2 datasheet, ST7MDT2-DVP2 pinout, ST7MDT2-DVP2 application, or ST7MDT2-DVP2 equivalent, this board serves as a production-ready debug and programming platform for ST7 Flash/OTP/EPROM MCUs - especially where CAN-less and CAN-enabled ST7 MDT2 variants require hardware-in-the-loop validation, ISP integration, or low-level register inspection.

Technical Context

The ST7MDT2-DVP2 implements a parallel-port–based JTAG-compatible emulation architecture with real-time trace buffer capture, enabling instruction-level visibility during MCU execution. It supports both on-board programming via ZIF sockets and in-situ programming via 10-pin ISP cable connected to target boards.

Hardware includes dual passive probe interfaces (50-pin flat cables), EMC ferrites for compliance, and jumper-configurable power supply options (5 V ±0.25 V, 1 A). The board lacks onboard enclosure, requiring ESD-safe handling and external DC input or JP1-fed regulated supply.

FAQ

Does ST7MDT2-DVP2 support CAN-enabled ST7 MCUs?

Yes - the ST7MDT2-DVP2 supports the ST7511R9 MDT2 CAN family alongside CAN-less variants like ST72334. Chapter 5.6 of the User Manual explicitly documents CAN features, including signal routing and trigger configuration for CAN bus monitoring and debugging.

What software tools ship with the ST7MDT2-DVP2 kit?

The "MCU on CD" includes STVD7 (source-level debugger), ST7 Windows Epromer (programming utility), ST7 Assembly Toolchain (assembler/linker/librarian), third-party C compiler demos (Hiware/Cosmic), application notes, datasheets, and training materials - all pre-validated for Windows 95/98/2000/NT.

Can ST7MDT2-DVP2 perform in-situ programming (ISP)?

Yes - it includes a dedicated 10-pin ISP flat cable and supports ISP for ST7 Flash MCUs that implement the feature. Figure 3 and Section 1.1 confirm ISP operation by connecting the board's ISP target connector to the user's application board via the passive probe interface.

Is ST7MDT2-DVP2 compliant with safety standards for life-support equipment?

No - per the manual's cover page and Appendix A, ST7MDT2-DVP2 is explicitly excluded from use in life support devices or systems without STMicroelectronics' written authorization. It carries the warning: "USE IN LIFE SUPPORT DEVICES OR SYSTEMS MUST BE EXPRESSLY AUTHORIZED."
