Product details
Overview
ST7MDTU3-EMU3 from STMicroelectronics is a third-generation real-time in-circuit emulator and debugger for ST7 Flash microcontrollers, supporting both emulation (replacing target ST7) and In-Circuit Communication (ICC) modes. It delivers 256K real-time trace with timestamp, unlimited conditional breakpoints, programmable clock (32 kHz–16 MHz), low-voltage operation (1.8–5.5 V), and four-level logic sequencer control - used in embedded firmware development labs for automotive body controllers and industrial PLC firmware validation.
For engineers reviewing the ST7MDTU3-EMU3 datasheet, ST7MDTU3-EMU3 pinout, ST7MDTU3-EMU3 application, or ST7MDTU3-EMU3 equivalent, this tool enables full-cycle ST7 software development - including real-time trace capture, memory/register read/write on-the-fly, option byte configuration, and in-circuit programming of Flash-based ST7 devices via parallel/USB/Ethernet host interface.
Technical Context
The ST7MDTU3-EMU3 implements dual-mode architecture: Emulation Configuration uses a Target Emulation Board (TEB) to physically replace the ST7 on the application board, enabling full visibility into execution flow, memory access, and register state; ICC Configuration connects via a 10-pin ICC header soldered to the board, allowing non-intrusive debugging and programming of the installed ST7 Flash MCU.
It integrates ST Micro Connect interface hardware for host PC communication, supports STVD7 IDE for build/debug/program workflows, and relies on STVP7 for advanced Flash memory operations - all coordinated through real-time control logic that synchronizes trace triggers, breakpoint conditions, and sequencer actions with address/data/event criteria.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Emulation Mode | Replaces target ST7 on board using TEB and package-specific adapters - enables full register/memory visibility and trace without modifying target hardware |
| ICC Mode | Connects via 10-pin ICC header - allows live debugging and Flash programming of installed ST7 without removal |
| Trace Memory | 256K bytes with timestamp - captures instruction/data bus activity for performance analysis and timing-critical bug isolation |
| Breakpoint Capability | Unlimited software breakpoints in RAM/XFlash; advanced hardware breakpoints on address/data/opcode/stack with mask and range conditions |
| Clock Range | Programmable 32 kHz to 16 MHz - matches target ST7 operating frequencies for accurate cycle-accurate emulation |
| Supply Voltage | 1.8 V to 5.5 V - supports wide-range ST7 variants including low-power and extended-voltage derivatives |
| Host Interface | Parallel, USB, or Ethernet - provides flexible connectivity options for lab integration and remote development environments |

FAQ
What host PC interfaces does the ST7MDTU3-EMU3 support?
The ST7MDTU3-EMU3 supports parallel port, USB, and Ethernet connections to the host PC via its ST Micro Connect interface module. Each interface enables full functionality - including real-time trace, breakpoint control, memory access, and Flash programming - with driver and software support provided by STVD7 and STVP7. No additional interface converters or dongles are required.
Can the ST7MDTU3-EMU3 debug and program ST7 devices already soldered on a PCB?
Yes - in ICC mode, the ST7MDTU3-EMU3 connects to a 10-pin ICC header installed on the target board, enabling full in-circuit debugging and Flash programming of soldered ST7 microcontrollers. This requires no device removal or socketing, and supports all ST7 Flash variants compatible with the ST7MDTxx sub-family.
What is the role of the Target Emulation Board (TEB) in ST7MDTU3-EMU3 operation?
The TEB is a replaceable daughterboard within the EMU3 probe that emulates a specific ST7 sub-family. It provides pin-compatible signal translation, voltage adaptation, and clock generation to substitute for the physical ST7 on the application board during emulation mode - enabling complete visibility into execution, memory, and peripheral behavior.
Does ST7MDTU3-EMU3 require additional software to function?
Yes - it requires STMicroelectronics' ST7 Visual Develop (STVD7) for integrated build/debug workflows and ST7 Visual Programmer (STVP7) for standalone Flash memory programming. Both are Windows-based, freely downloadable tools that communicate directly with the EMU3 hardware via ST Micro Connect drivers.
