Renesas QB-64GK-HQ-01T

Overview

QB-64GK-HQ-01T from Renesas Electronics is a high-quality emulation probe adapter designed for RL78/G13 and RL78/G14 microcontrollers in 64-pin LQFP (10×10 mm) and 64-pin LQFP (12×12 mm) packages. It supports HQ (High-Quality) connector interface, enables reliable in-circuit debugging and flash programming via IECUBE main unit, and is used with QB-64FA-EA-01T or QB-64FB-EA-01T socket sets in industrial MCU development workflows.

For engineers reviewing the QB-64GK-HQ-01T datasheet, QB-64GK-HQ-01T pinout, QB-64GK-HQ-01T application, or QB-64GK-HQ-01T equivalent, this part serves as a critical signal-integrity-preserving interface between Renesas IECUBE debug hardware and target RL78-based boards - especially where stable JTAG/SWCLK timing, low-noise probe coupling, and mechanical alignment with 0.5 mm pitch LQFP are required.

Technical Context

The QB-64GK-HQ-01T is a passive mechanical and electrical interface module - not an active IC - that routes debug signals (RESET, CLK, TDI, TDO, TMS, TRST) and power lines between the IECUBE main unit and target RL78 MCU sockets. It implements impedance-matched trace routing and gold-plated contact surfaces to maintain signal fidelity up to 10 MHz SWD clock rates.

It is mechanically keyed for unambiguous orientation on QB-64FA-EA-01T/QB-64FB-EA-01T sockets and electrically optimized for RL78's 3.3 V I/O voltage domain. No firmware, configuration, or voltage translation is performed - its function is strictly physical layer bridging with minimal insertion loss and crosstalk.

FAQ

What is the primary function of the QB-64GK-HQ-01T?

The QB-64GK-HQ-01T is a passive high-fidelity emulation probe adapter that physically and electrically bridges the Renesas IECUBE main unit to RL78/G13 or RL78/G14 microcontrollers in 64-pin LQFP packages. It ensures precise signal routing for SWD/JTAG debugging and programming without active circuitry - QB-64GK-HQ-01T maintains signal integrity, mechanical alignment, and contact reliability during repeated connect/disconnect cycles in lab and production environments.

Which socket sets is QB-64GK-HQ-01T compatible with?

QB-64GK-HQ-01T is specifically designed for use with QB-64FA-EA-01T and QB-64FB-EA-01T socket sets. It is mechanically keyed and electrically mapped to match their pinout and mounting geometry. It is not compatible with YQ, NQ, or YS variants - QB-64GK-HQ-01T only interfaces with EA-series sockets intended for RL78/G13 and G14 64-pin LQFP devices.

Does QB-64GK-HQ-01T require external power or configuration?

No - QB-64GK-HQ-01T is a fully passive adapter with no active components, no firmware, and no power input. It draws no current and requires no setup or configuration. All functionality is inherent in its precision PCB layout and HQ connector interface - QB-64GK-HQ-01T operates transparently once correctly mounted between the IECUBE main unit and compatible socket.

Can QB-64GK-HQ-01T be used with RL78/G12 or RL78/G1A MCUs?

No - QB-64GK-HQ-01T is qualified only for RL78/G13 and RL78/G14 families in 64-pin LQFP packages. RL78/G12 uses different pinouts and socket requirements (e.g., QB-20SP-EA-04T), and RL78/G1A targets distinct packages like 48-pin LQFP - QB-64GK-HQ-01T does not support those families or footprints.

Is QB-64GK-HQ-01T still in active production and supported by Renesas?

Yes - QB-64GK-HQ-01T remains an active, supported part within the IECUBE ecosystem. While the full IECUBE set was discontinued in May 2015, individual components including QB-64GK-HQ-01T continue to be manufactured and distributed by Renesas and authorized partners. Documentation, mechanical drawings, and compatibility guidance for QB-64GK-HQ-01T are maintained in current Renesas IECUBE user manuals.
