Renesas QB-176GM-HQ-01T

Overview

QB-176GM-HQ-01T from Renesas Electronics is a Mount Adapter designed for the QB-V850E2FX4H-PD in-circuit emulator POD, enabling mechanical and electrical interface between the IE850 main unit and V850E2/FL4-H or V850E2/FK4-G target microcontrollers in P-FQFP208 or P272F1 packages. It supports 3.3V/5.0V target system interface voltage, operates at up to 160MHz CPU clock emulation, and maintains signal integrity across 176-pin high-density routing with controlled impedance traces.

For engineers reviewing the QB-176GM-HQ-01T datasheet, QB-176GM-HQ-01T pinout, QB-176GM-HQ-01T application, or QB-176GM-HQ-01T equivalent, this adapter is critical for hardware-in-the-loop debugging of V850E2-based automotive control units, industrial PLCs, and real-time motor drives requiring trace-enabled firmware validation and cycle-accurate timing analysis.

Technical Context

The QB-176GM-HQ-01T is a passive mechanical-electrical interface component that mates with QB-176GM-YQ-01T (Emulator Connector) and QB-176GM-NQ-01T (Target Connector) to form a complete debug probe assembly. It provides precise alignment, thermal stability, and ESD-safe grounding paths for high-speed JTAG and trace signal routing between IE850 and target devices.

It is qualified for use with V850E2/FL4-H and V850E2/FK4-G microcontrollers operating at 3.0–5.0V supply ranges and supports full trace capture, hardware breakpoint insertion, and real-time execution monitoring without signal degradation or timing skew.

FAQ

What is the primary function of the QB-176GM-HQ-01T in the IE850 debug system?

The QB-176GM-HQ-01T is a Mount Adapter that mechanically secures and electrically interfaces the QB-V850E2FX4H-PD POD to target boards hosting V850E2/FL4-H or V850E2/FK4-G microcontrollers. It ensures precise alignment, low-inductance ground return paths, and signal integrity for JTAG, trace, and power lines-enabling reliable connection without misalignment or contact resistance issues during repeated debug sessions. QB-176GM-HQ-01T does not contain active circuitry or logic.

Which target microcontroller packages are supported by QB-176GM-HQ-01T?

QB-176GM-HQ-01T supports two specific package types: P-FQFP208 (used by V850E2/FL4-H) and P272F1 (used by V850E2/FK4-G). It is not compatible with V850E2/FG4, V850E2/FJ4, or other variants listed in the QB-V850E2FX4H-PD manual. The adapter's footprint and pin pitch match only these two packages, as confirmed in Table 1-2 of the user's manual.

Does QB-176GM-HQ-01T require external power or configuration?

No. QB-176GM-HQ-01T is a passive mechanical adapter with no active components, power pins, or configuration options. It draws no current and contains no firmware, jumpers, or DIP switches. All power and signal conditioning is handled by the QB-V850E2FX4H-PD POD and IE850 main unit. QB-176GM-HQ-01T functions solely as a precision interconnect carrier.

Can QB-176GM-HQ-01T be used with other Renesas emulators like E2 or E20?

No. QB-176GM-HQ-01T is exclusively designed for use with the QB-V850E2FX4H-PD POD and IE850 main unit. It is not mechanically or electrically compatible with E2 or E20 emulator families due to differing connector layouts, pin counts, signal assignments, and mechanical mounting requirements. Using it with non-IE850 systems may cause physical damage or signal misrouting.

Is QB-176GM-HQ-01T compliant with RoHS and REACH regulations?

Yes. As a Renesas Electronics product, QB-176GM-HQ-01T complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No 1907/2006, consistent with Renesas' environmental policy stated in Section 8 of the QB-V850E2FX4H-PD User's Manual. Lead-free solderability and halogen-free materials are verified per standard qualification testing.
