Renesas QB-100GC-HQ-01T

Overview

QB-100GC-HQ-01T from Renesas Electronics is a mount adapter designed for in-circuit emulation of 78K0R/FX3 and 78K0R/HX3 microcontrollers in 100-pin LQFP (100GC) packages. It enables secure mechanical mounting of the target device onto the QB-78K0RFX3 emulator system, supports precise pin alignment via guide pins, and is rated for operation at 2.7–5.5 V supply voltage with compatibility for high-speed system clocks up to 24 MHz.

For engineers reviewing the QB-100GC-HQ-01T datasheet, QB-100GC-HQ-01T pinout, QB-100GC-HQ-01T application, or QB-100GC-HQ-01T equivalent, this part is critical for establishing reliable physical interface between the QB-78K0RFX3 emulator and 100-pin LQFP-packaged 78K0R devices - especially during debug setup requiring stable mechanical registration, thermal-safe soldering (≤260°C × 10 s), and GND-potential-matched target system connection.

Technical Context

QB-100GC-HQ-01T is a passive mechanical interface component used exclusively with the QB-78K0RFX3 in-circuit emulator. It mates directly with the QB-100GC-NQ-01T target connector and accommodates 100-pin LQFP (100GC) packaged 78K0R/FX3 and 78K0R/HX3 MCUs. Its design includes alignment guide pins and solder pads matching the target device's footprint, enabling reflow-compatible mounting (260°C × 10 s max).

The adapter does not contain active circuitry, power regulation, or signal conditioning. It functions solely as a zero-insertion-force (ZIF)-adjacent mechanical bridge - ensuring consistent electrical contact integrity between emulator probe (QB-144-EP-02S) and target IC during real-time debugging sessions involving Go/Step/Trace functions, memory/register manipulation, and break-point execution control.

FAQ

What is the primary function of QB-100GC-HQ-01T in the QB-78K0RFX3 emulator system?

QB-100GC-HQ-01T is a mount adapter that mechanically secures 100-pin LQFP-packaged 78K0R/FX3 and 78K0R/HX3 microcontrollers to the QB-78K0RFX3 emulator platform. It ensures precise alignment and stable soldered attachment between the target device and QB-100GC-NQ-01T target connector, enabling reliable signal integrity during real-time debugging operations using QB-144-EP-02S emulation probe. QB-100GC-HQ-01T itself contains no active circuitry.

Which target devices are compatible with QB-100GC-HQ-01T?

QB-100GC-HQ-01T is explicitly designated for use with 78K0R/FX3 and 78K0R/HX3 microcontrollers housed in 100-pin LQFP (100GC) packages - including 78K0R/FG3 and 78K0R/HG3 variants listed in Table 1-3 of the QB-78K0RFX3 User's Manual. It is not compatible with smaller packages (e.g., 48GA, 64GB) or non-LQFP footprints.

Does QB-100GC-HQ-01T require power or generate signals?

No. QB-100GC-HQ-01T is a passive mechanical adapter with no electrical functionality. It does not require power, contain ICs, or condition signals. Its role is strictly physical: providing accurate pad alignment, guide-pin-assisted placement, and thermally robust solder joint formation between the target MCU and the QB-78K0RFX3 emulator interface chain.

What are the recommended soldering conditions for QB-100GC-HQ-01T?

QB-100GC-HQ-01T supports standard reflow soldering at 260°C for ≤10 seconds, or manual soldering at ≤350°C for ≤5 seconds per pin. Cleaning by flux immersion or vapor phase is prohibited. The adapter must be mounted before soldering the target device to prevent flux contamination of contact surfaces - consistent with the procedure defined for QB-100GC-NQ-01T in Section 2.3.1 of the QB-78K0RFX3 manual.

Can QB-100GC-HQ-01T be used without other QB-78K0RFX3 accessories?

No. QB-100GC-HQ-01T requires coordinated use with QB-100GC-NQ-01T (target connector), QB-100GC-YQ-01T (YQ connector), QB-100GC-EA-09T (exchange adapter), and QB-144-EP-02S (emulation probe) to complete the physical debug interface path. It is not functional as a standalone component and has no electrical interface outside this defined assembly.
