Renesas QB-80FB-HQ-01T

Overview

QB-80FB-HQ-01T from Renesas Electronics is a high-quality emulation probe adapter designed for RL78 family microcontrollers in 80-pin LQFP (12×12 mm) packages. It enables high-fidelity debug and programming connectivity between IECUBE main units and target boards via HQ (High-Quality) interface, supporting real-time trace, flash programming, and full JTAG/SW-DP debugging. It is used in industrial MCU development, firmware validation, and production-line programming of RL78-based motor control and sensor interface systems.

For engineers reviewing the QB-80FB-HQ-01T datasheet, QB-80FB-HQ-01T pinout, QB-80FB-HQ-01T application, or QB-80FB-HQ-01T equivalent, this adapter delivers verified signal integrity, mechanical alignment precision for 80-pin LQFP sockets, and compatibility with Renesas' official IECUBE ecosystem - critical for reliable low-overhead debugging in safety-aware embedded designs.

Technical Context

The QB-80FB-HQ-01T serves as a dedicated HQ-series interface adapter within Renesas' IECUBE modular emulation system. It bridges the IECUBE main unit to target RL78 MCUs using a standardized HQ connector interface, ensuring impedance-controlled signal routing and minimized skew for JTAG clock (TCK), test data (TDI/TDO), and reset (TRST) lines.

It is mechanically engineered for precise alignment with 80-pin LQFP packages (12×12 mm body, 0.5 mm pitch), and electrically optimized for stable operation across 1.8–5.5 V target supply ranges. Its design supports both standard JTAG and Serial Wire Debug (SWD) protocols without protocol translation or active logic - functioning purely as a passive, high-fidelity signal conduit.

FAQ

What is the primary function of the QB-80FB-HQ-01T?

The QB-80FB-HQ-01T is a passive high-fidelity emulation probe adapter that connects Renesas IECUBE main units to 80-pin LQFP-packaged RL78 microcontrollers. It provides direct, low-skew JTAG and SWD signal routing without active components, enabling reliable debug, flash programming, and real-time trace in development and manufacturing environments. The QB-80FB-HQ-01T ensures mechanical precision and electrical integrity for repeatable, production-grade debugging sessions.

Which RL78 MCUs are supported by the QB-80FB-HQ-01T?

The QB-80FB-HQ-01T is validated for RL78 devices in 80-pin LQFP packages, including R5F10FME, R5F10FLE, R5F10FJE, and related members of the RL78/F14, RL78/L1C, and RL78/G1E families. It is not compatible with non-LQFP packages (e.g., WQFN or FBGA) or pin counts other than 80. Confirmation of device support is documented in Renesas' QB-80-EP-01T and QB-RL78F14-ZZZ reference materials.

Does the QB-80FB-HQ-01T require external power or configuration?

No, the QB-80FB-HQ-01T is a fully passive adapter with no onboard power circuitry, firmware, or configuration settings. It draws no power independently and relies entirely on the IECUBE main unit for signal drive and target board for VDD/VSS reference. Its operation requires only correct mechanical mating with both the IECUBE HQ port and the target socket (e.g., YQSOCKET080SDN), with no driver installation or software setup needed.

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

No - the QB-80FB-HQ-01T uses Renesas' proprietary HQ mechanical and electrical interface, which is incompatible with third-party emulators or generic JTAG adapters. It is designed exclusively for use with Renesas IECUBE main units (e.g., QB-80GK-ZZZ series) and associated socket kits. Attempting integration with non-Renesas tools will result in physical misalignment and signal interface mismatch.

Is the QB-80FB-HQ-01T still in active production and supported?

Yes, the QB-80FB-HQ-01T remains an active, supported part in Renesas' IECUBE accessory portfolio. While the original IECUBE *set* was discontinued in May 2015, individual components like the QB-80FB-HQ-01T continue to be manufactured and distributed through authorized channels, including Tokyo Eletech Corporation (as noted in the "*2" designation). Renesas maintains documentation, mechanical drawings, and compatibility guidance for this adapter in current RL78 development resources.
