Renesas QB-80GC-NQ-01T

Overview

QB-80GC-NQ-01T from Renesas Electronics is a target connector adapter designed for RL78 family microcontrollers in 80-pin LQFP (12×12 mm) packages, enabling high-fidelity debug and emulation connectivity between IECUBE main units and target boards via NQ-series interface. It supports RL78/G13, RL78/G14, RL78/F12–F15, and RL78/L1C devices, features 80-position low-profile surface-mount termination, and delivers stable signal integrity for SWD/JTAG-based programming and real-time trace.

For engineers reviewing the QB-80GC-NQ-01T datasheet, QB-80GC-NQ-01T pinout, QB-80GC-NQ-01T application, or QB-80GC-NQ-01T equivalent, this adapter is critical for validating firmware on production-grade RL78 targets during development, qualification, and failure analysis-especially where mechanical clearance, thermal stability, and repeatable probe contact are required.

Technical Context

The QB-80GC-NQ-01T implements a passive, impedance-matched 1:1 signal routing architecture with no active components or level-shifting circuitry. It maps all essential RL78 debug pins-including RESET, SWCLK, SWDIO, VDD, VSS, and optional trace clock/data lines-to corresponding NQ-series emulation probe interface signals per Renesas' IECUBE specification.

It is mechanically engineered to align precisely with 80-pin LQFP footprints (12×12 mm, 0.5 mm pitch), uses gold-plated beryllium copper contacts rated for ≥500 mating cycles, and complies with RoHS and JEDEC J-STD-020 moisture sensitivity level MSL3.

FAQ

What is the primary function of the QB-80GC-NQ-01T?

The QB-80GC-NQ-01T is a passive target connector adapter that bridges Renesas IECUBE emulation probes to RL78 microcontrollers in 80-pin LQFP packages. It enables reliable SWD/JTAG communication for programming, debugging, and real-time trace without signal conditioning or voltage translation. The QB-80GC-NQ-01T ensures mechanical alignment, contact durability, and signal fidelity for production-grade development workflows.

Which RL78 microcontrollers are compatible with QB-80GC-NQ-01T?

QB-80GC-NQ-01T supports RL78 devices packaged in 80-pin LQFP (12×12 mm), including RL78/G13, G14, F12–F15, and L1C series MCUs such as R5F10FME, R5F10YFE, R5F11LAC, and R5F11LBC. Compatibility is confirmed by Renesas' official IECUBE socket set documentation and device support mapping for the NQ interface variant.

Does QB-80GC-NQ-01T require external power or configuration?

No. QB-80GC-NQ-01T is a fully passive adapter with no active circuitry, power input, or configuration options. It routes debug signals directly from the IECUBE NQ probe to the target RL78 MCU's debug header. Power is supplied separately to the target board; the QB-80GC-NQ-01T itself draws zero current and requires no setup beyond mechanical mounting.

How does QB-80GC-NQ-01T differ from QB-80FB-NQ-01T?

QB-80GC-NQ-01T and QB-80FB-NQ-01T both serve 80-pin LQFP RL78 targets but map to different MCU subfamilies: QB-80GC-NQ-01T is designated for RL78/G13, G14, and L1C devices, while QB-80FB-NQ-01T supports RL78/G1A, G1C, and F12–F14 variants. Their pinouts match respective device-specific debug signal allocations-even though physical package dimensions are identical.

Is QB-80GC-NQ-01T still in production and supported by Renesas?

Yes. Although the full IECUBE set was discontinued in May 2015, individual components like QB-80GC-NQ-01T remain orderable and supported as spares and replacements. Renesas continues to publish updated user manuals and compatibility notes for QB-80GC-NQ-01T in its RL78 debugging documentation, confirming ongoing technical and supply-chain viability.
