Renesas QB-64GK-YQ-01T

Overview

QB-64GK-YQ-01T from Renesas Electronics is a YQ-series emulation probe adapter designed for RL78 family microcontrollers in 64-pin FBGA (4×4 mm) packages. It provides high-fidelity debug signaling, supports full-speed real-time trace, and enables secure on-chip debugging via the on-chip debug interface. It is used with IECUBE main units for firmware development and validation of RL78/G1A, RL78/L12, and RL78/L1C MCUs.

For engineers reviewing the QB-64GK-YQ-01T datasheet, QB-64GK-YQ-01T pinout, QB-64GK-YQ-01T application, or QB-64GK-YQ-01T equivalent, this adapter delivers verified signal integrity for SWD/JTAG-level debug sessions, supports voltage translation for 1.8 V–5.0 V target systems, and integrates mechanical alignment features for repeatable FBGA socket engagement.

Technical Context

The QB-64GK-YQ-01T implements a passive, impedance-matched signal routing architecture between the IECUBE main unit and RL78 targets. It routes all required debug signals - including RESET, CLK, TDI, TDO, TMS, TCK, and VTREF - with controlled trace length and minimized crosstalk.

It is mechanically engineered for precise mating with YQPACK064SD socket modules and compatible with QB-64FA-EA-01T/QB-64FB-EA-01T main units. The adapter does not include active logic or level-shifting ICs; signal conditioning relies on layout-defined impedance control and termination matching per Renesas debug interface specifications.

FAQ

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

The QB-64GK-YQ-01T is a YQ-series emulation probe adapter that bridges the IECUBE main unit to RL78 microcontrollers in 64-pin FBGA packages. It ensures accurate, low-noise transmission of debug signals (JTAG/SWD) and supports VTREF-based voltage domain adaptation. QB-64GK-YQ-01T does not perform protocol translation or signal regeneration - its role is strictly mechanical and electrical interconnection.

Which RL78 MCUs are explicitly supported by QB-64GK-YQ-01T?

QB-64GK-YQ-01T is documented for use with RL78/G1A (e.g., R5F10FLE), RL78/L12 (e.g., R5F10FME), and RL78/L1C (e.g., R5F10FGE) devices in 64-pin FBGA packages. Support is confirmed via Renesas' IECUBE optional product list and socket compatibility mapping to YQPACK064SD/YQSOCKET064SDN modules.

Is QB-64GK-YQ-01T compatible with IECUBE main units other than QB-64FA-EA-01T?

Yes - QB-64GK-YQ-01T is mechanically and electrically compatible with any IECUBE main unit bearing the "YQ" interface designation, including QB-64FB-EA-01T and QB-64FA-EA-01T. It is not compatible with NQ, HQ, or YS variants due to connector keying and pin assignment differences.

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

No - QB-64GK-YQ-01T is a passive adapter with no active components, firmware, or configuration requirements. It draws no power beyond what is supplied through the debug interface (VTREF, TCK, etc.) from the IECUBE main unit or target board. No drivers, software setup, or calibration is needed for operation.

Can QB-64GK-YQ-01T be used with non-Renesas debug tools?

No - QB-64GK-YQ-01T is designed exclusively for Renesas IECUBE systems and relies on proprietary mechanical alignment, pinout mapping, and signal timing defined in the IECUBE specification. It is not interoperable with third-party debug probes, Segger J-Link, or ST-LINK adapters due to incompatible connector geometry and signal routing.
