Renesas QB-80GK-YQ-01T

Overview

QB-80GK-YQ-01T from Renesas Electronics is an emulation probe adapter designed for RL78 family microcontrollers, specifically supporting 80-pin LQFP-packaged devices including R5F10FME and RL78/G1E variants. It provides YQ-series target connector interface, enables in-circuit debugging via IECUBE main unit, and delivers stable signal integrity for JTAG/SWCLK-based programming and real-time trace.

For engineers reviewing the QB-80GK-YQ-01T datasheet, QB-80GK-YQ-01T pinout, QB-80GK-YQ-01T application, or QB-80GK-YQ-01T equivalent, this adapter is essential for establishing reliable debug connectivity between IECUBE hardware and 80-pin RL78 targets-particularly where YQ connector compatibility, mechanical alignment with LQFP-80 footprints, and signal fidelity under 10 MHz debug clock rates are required.

Technical Context

The QB-80GK-YQ-01T functions as a passive mechanical and electrical interface between the IECUBE main unit (e.g., QB-80FB-EA-04T) and RL78 microcontrollers in 80-pin LQFP (12×12 mm) packages. It maps standard IECUBE debug signals-including TCK, TMS, TDI, TDO, TRST, and reset-to corresponding pins on the target MCU using verified pinout alignment per Renesas Application Note U17950EJ4V0UM00.

It supports YQ-series target connectors and is paired with YQSOCKET080SDN socket and YQPACK080SD pack, forming a complete debug interface stack for RL78/G1E, RL78/F12, and RL78/L1C devices. No active logic or voltage translation is implemented; signal integrity relies on controlled impedance routing and gold-plated contact surfaces rated for ≥500 mating cycles.

FAQ

What is the primary function of QB-80GK-YQ-01T in the IECUBE ecosystem?

QB-80GK-YQ-01T serves as a dedicated YQ-series emulation probe adapter that bridges the IECUBE main unit to 80-pin LQFP-packaged RL78 microcontrollers. It ensures correct signal routing for JTAG/SWD debugging, maintains mechanical alignment with the target socket (YQSOCKET080SDN), and enables reliable firmware download and real-time trace without signal degradation. QB-80GK-YQ-01T is not a standalone programmer but a critical interconnect within the full IECUBE debug chain.

Which RL78 microcontrollers are explicitly supported by QB-80GK-YQ-01T?

QB-80GK-YQ-01T supports RL78 devices in 80-pin LQFP packages, including R5F10FME (RL78/G1E), RL78/F12, RL78/L1C, and RL78/L13. Compatibility is confirmed via Renesas' official IECUBE optional product list and aligns with the QB-80FB-EA-04T and QB-80FB-EA-07T main units. Devices must use the standard RL78 debug interface pinout defined in their respective hardware user's manuals.

Can QB-80GK-YQ-01T be used with non-Renesas debug tools?

No - QB-80GK-YQ-01T is mechanically and electrically optimized exclusively for Renesas IECUBE systems. Its pin layout, connector interface (YQ), and signal assignments match only IECUBE main units (e.g., QB-80FB-EA-xx) and associated sockets (YQSOCKET080SDN). It lacks standard ARM CMSIS-DAP or J-Link pinout compatibility and is not interoperable with third-party debug probes or generic JTAG adapters.

Is QB-80GK-YQ-01T still in active production or discontinued?

QB-80GK-YQ-01T remains an active, orderable part. While Renesas ended sales of the full IECUBE *set* in May 2015, individual components-including QB-80GK-YQ-01T-are still manufactured and distributed through authorized channels like Tokyo Eletech Corporation (per note *2 in source documentation). No discontinuation notice (*1) applies to this part number.

What配套 components are required to use QB-80GK-YQ-01T?

To deploy QB-80GK-YQ-01T, you require: (1) an IECUBE main unit (e.g., QB-80FB-EA-04T), (2) YQSOCKET080SDN target socket, (3) YQPACK080SD adapter pack, and (4) compatible RL78 MCU in 80-pin LQFP. Power-supply adapter QB-COMMON-PW-xx is optional but recommended for stable VDD delivery. QB-80GK-YQ-01T alone cannot perform debugging-it functions only as part of this validated hardware stack.
