Renesas QB-100GC-NQ-01T

Overview

QB-100GC-NQ-01T from Renesas Electronics is a target connector designed for in-circuit emulation of 78K0R/HG3 and 78K0R/FG3 microcontrollers in 100-pin LQFP (14 × 14 mm) package configurations. It provides mechanical and electrical interface between the QB-78K0RFX3 emulator and target board, supports 2.7–5.5 V operation, features gold-plated contacts for reliable signal integrity, and is used with QB-100GC-YQ-01T YQ connector and QB-100GC-EA-09T exchange adapter.

For engineers reviewing the QB-100GC-NQ-01T datasheet, QB-100GC-NQ-01T pinout, QB-100GC-NQ-01T application, or QB-100GC-NQ-01T equivalent, this page delivers verified mechanical interface specs, soldering conditions (260°C × 10 s max reflow), alignment guide pin placement, epoxy mounting guidance, and compatibility with QB-78K0RFX3-based debug setups for 100-pin 78K0R/FX3 and 78K0R/Hx3 devices.

Technical Context

QB-100GC-NQ-01T is a fixed-position, surface-mount target connector with 100 contact positions matching the 0.5 mm pitch LQFP-100 footprint of 78K0R/FG3 and 78K0R/HG3 MCUs. It integrates two non-through alignment guide holes (φ1.0 mm) for precise pad registration and is intended for permanent soldering onto the target PCB prior to emulator connection via YQ and EA adapters.

The connector enables full-signal access-including power, ground, reset, clock, and debug I/O-for real-time emulation functions such as Go/Step/Trace, software breakpoints (2000 points), and memory/register manipulation. Its design requires strict adherence to specified soldering profiles and prohibits flux immersion cleaning to preserve contact reliability.

FAQ

What is the primary function of QB-100GC-NQ-01T in a debug setup?

QB-100GC-NQ-01T serves as the permanently mounted target-side interface that electrically and mechanically bridges the QB-78K0RFX3 emulator to a 100-pin LQFP 78K0R/FG3 or 78K0R/HG3 microcontroller on the user's PCB. It enables full-signal access for real-time execution, breakpoint, trace, and memory manipulation functions without requiring socketed ICs or wire-wrap modifications.

Which microcontroller packages is QB-100GC-NQ-01T compatible with?

QB-100GC-NQ-01T is explicitly designed for 100-pin LQFP packages with 0.5 mm pitch, specifically supporting the 78K0R/FG3 and 78K0R/HG3 microcontrollers as confirmed in Table 1-3 of the QB-78K0RFX3 User's Manual. It is not compatible with QFN, TQFP-64, or other pin counts or pitches.

How is QB-100GC-NQ-01T mounted to the target PCB?

QB-100GC-NQ-01T is mounted using two-component epoxy adhesive applied to its four base projections, followed by alignment via its φ1.0 mm guide holes, then soldered using either reflow (260°C × ≤10 s) or manual (350°C × ≤5 s per pin) methods. Mounting must occur with both emulator and target system powered off, and flux immersion cleaning is strictly prohibited.

What accessories are required to use QB-100GC-NQ-01T with QB-78K0RFX3?

To complete the debug chain, QB-100GC-NQ-01T requires QB-100GC-YQ-01T (YQ connector), QB-100GC-EA-09T (exchange adapter), and QB-144-EP-02S (emulation probe). These components are bundled with the QB-78K0RFX3-T100GC order variant and are necessary for signal routing, pin conversion, and physical coupling to the emulator unit.

Does QB-100GC-NQ-01T support hot-plugging or live connection?

No. QB-100GC-NQ-01T must be soldered to the target PCB while both the target system and QB-78K0RFX3 are powered off. The User's Manual explicitly prohibits plugging/unplugging connectors while powered, citing risk of GND potential difference damage, contact arcing, and irreversible connector degradation - making live connection unsafe and unsupported.
