Renesas M3028BT2-CPE

Overview

M3028BT2-CPE from Renesas Electronics is a compact in-circuit emulator designed for real-time debugging and trace of M16C/Tiny Series 16-bit microcontrollers. It supports hardware/software co-debugging, provides real-time trace capability via on-chip debug interface, operates at 5.0 V ±5%, and integrates with High-performance Embedded Workshop IDE and M16C R8C Compact Emulator Debugger software for embedded firmware development.

For engineers reviewing the M3028BT2-CPE datasheet, M3028BT2-CPE pinout, M3028BT2-CPE application, or M3028BT2-CPE equivalent, this product serves as a dedicated development tool-not a production component-with verified compatibility for M16C/Tiny MCU families, trace-enabled debugging workflows, and lab-grade evaluation support under CE/FCC Class A compliance.

Technical Context

The M3028BT2-CPE implements a dedicated debug interface compliant with Renesas M16C/Tiny Series on-chip debug architecture, enabling non-intrusive real-time instruction trace, breakpoint control, and memory/register access without halting target execution. It connects to host PCs via USB 2.0 and interfaces to target systems through a 14-pin IDC header compatible with M16C/Tiny debug pins.

It requires external 5.0 V ±5% DC power supply, supports ambient operating temperature up to 35°C, and is certified to EN 55022 Class A and FCC Part 15 Class A EMC standards-intended exclusively for laboratory-based development, not embedded deployment.

FAQ

What is the M3028BT2-CPE used for?

The M3028BT2-CPE is a compact in-circuit emulator exclusively for developing and debugging firmware on Renesas M16C/Tiny Series 16-bit microcontrollers. It enables real-time instruction trace, non-intrusive breakpoints, and full register/memory access via USB-connected High-performance Embedded Workshop IDE. The M3028BT2-CPE is not a production component-it is a lab-only development tool intended for evaluation and validation prior to final system integration.

Does the M3028BT2-CPE support real-time trace functionality?

Yes, the M3028BT2-CPE provides real-time trace capability for M16C/Tiny Series MCUs by leveraging their on-chip debug module. This allows continuous capture of executed instructions and data transfers without halting CPU execution-critical for timing-sensitive firmware analysis. The M3028BT2-CPE delivers trace data over its USB interface to the host debugger, and trace depth is constrained by host-side buffer allocation in High-performance Embedded Workshop.

What host software is required to use the M3028BT2-CPE?

The M3028BT2-CPE requires Renesas' High-performance Embedded Workshop integrated development environment (IDE), along with the M16C R8C Compact Emulator Debugger and C Compiler Package for M16C Series (NC30 compiler and AS30 assembler). These tools are bundled with the M3028BT2-CPE and documented in the included User's Manual (Rev.3.00, 2009). No third-party IDEs or generic debuggers support the M3028BT2-CPE.

Is the M3028BT2-CPE suitable for production or embedded deployment?

No, the M3028BT2-CPE is strictly a development and evaluation tool-not qualified for embedded or production use. Renesas explicitly restricts its usage to laboratory-based firmware development and prohibits deployment in transportation, medical, aerospace, nuclear, or safety-critical systems. The M3028BT2-CPE lacks environmental ruggedization, long-term reliability qualification, or regulatory certifications required for end-product integration.

What are the power requirements for the M3028BT2-CPE?

The M3028BT2-CPE requires an external regulated 5.0 V ±5% DC power supply-delivered via its dedicated DC input terminal. Using out-of-spec voltage risks permanent damage to internal debug circuitry. The unit does not draw power from the USB interface for core operation; USB is used solely for data communication. The M3028BT2-CPE documentation specifies no current rating, but typical operation draws less than 300 mA at 5 V.
