Renesas QB-80GC-HQ-01T

Overview

QB-80GC-HQ-01T from Renesas Electronics is a high-quality emulation probe adapter designed for RL78 family microcontrollers in 80-pin LQFP packages. It provides HQ (High-Quality) signal integrity for JTAG/SW-DP debug interfaces, supports target voltage range of 1.8–5.5 V, and enables reliable in-circuit debugging and flash programming during embedded development. It is used with IECUBE main units for RL78/G1A, RL78/G1E, RL78/F12–F15, and RL78/L1C MCU evaluation.

For engineers reviewing the QB-80GC-HQ-01T datasheet, QB-80GC-HQ-01T pinout, QB-80GC-HQ-01T application, or QB-80GC-HQ-01T equivalent, this adapter delivers verified signal fidelity for high-speed SWD clock rates up to 10 MHz, low-noise probing on sensitive debug lines, and mechanical compatibility with standard 80-pin LQFP target boards using HQPACK080SB packaging.

Technical Context

The QB-80GC-HQ-01T is part of Renesas' IECUBE ecosystem and functions exclusively as a passive, impedance-matched interface between the IECUBE main unit (e.g., QB-80FB-EA-01T) and RL78 MCUs in 80-pin LQFP (12×12 mm) packages. It implements dedicated routing for TCK, TMS, TDI, TDO, nTRST, and SWDIO/SWCLK signals with controlled trace lengths and ground shielding.

It is paired with HQPACK080SB - a Tokyo Eletech Corporation-manufactured socket pack - and requires no firmware or configuration. Its design targets production-grade debug reliability, not just lab verification, and is validated for use with R5F10FME, R5F10FLE, and R5F10FGE series devices.

FAQ

What is the QB-80GC-HQ-01T used for?

The QB-80GC-HQ-01T is a high-fidelity emulation probe adapter that bridges Renesas IECUBE main units to RL78 microcontrollers in 80-pin LQFP packages. It ensures signal integrity for JTAG and SWD debugging, enabling reliable firmware download, real-time tracing, and non-intrusive breakpoint execution during development and validation of QB-80GC-HQ-01T-based systems.

Which RL78 MCUs are compatible with the QB-80GC-HQ-01T?

The QB-80GC-HQ-01T supports RL78 devices housed in 80-pin LQFP packages, including R5F10FME, R5F10FLE, R5F10FGE, and derivatives across the RL78/G1E, RL78/F14, RL78/F15, and RL78/L1C families. Compatibility is confirmed via pin mapping to the HQPACK080SB socket and alignment with QB-80FB-EA-01T main unit interface definitions.

Does the QB-80GC-HQ-01T require drivers or firmware?

No, the QB-80GC-HQ-01T is a passive hardware adapter with no active components, firmware, or driver dependencies. It operates transparently within the IECUBE toolchain - all debug protocol handling is performed by the main unit (e.g., QB-80FB-EA-01T) and host PC software such as CS+ or e2 studio. The QB-80GC-HQ-01T itself requires zero configuration.

Can the QB-80GC-HQ-01T be used with non-Renesas debug tools?

No - the QB-80GC-HQ-01T is mechanically and electrically optimized for Renesas IECUBE main units only. Its pinout, connector gender, and signal routing follow proprietary IECUBE specifications and are not interoperable with generic JTAG adapters, Segger J-Link, or ST-LINK hardware. Use of QB-80GC-HQ-01T mandates an IECUBE-compatible main unit like QB-80FB-EA-01T.

Is the QB-80GC-HQ-01T still in production?

Yes, the QB-80GC-HQ-01T remains an active, supported part in Renesas' IECUBE accessory portfolio. While the original IECUBE *set* was discontinued in May 2015, individual components including QB-80GC-HQ-01T continue to be manufactured and distributed through authorized channels, including Aetrix Electronics, for ongoing RL78 development and maintenance projects.
