Renesas QB-80FB-NQ-01T

Overview

QB-80FB-NQ-01T from Renesas Electronics is an NQ-series target connector adapter for the IECUBE in-circuit emulator, designed to interface with 80-pin LQFP-packaged RL78 family microcontrollers including RL78/G13, RL78/G14, RL78/F12–F15, and RL78/L1C. It supports high-fidelity debug signaling, low-noise probe coupling, and mechanical alignment with standard 0.5 mm pitch LQFP footprints.

For engineers reviewing the QB-80FB-NQ-01T datasheet, QB-80FB-NQ-01T pinout, QB-80FB-NQ-01T application, or QB-80FB-NQ-01T equivalent, this adapter enables reliable JTAG/SWJ-based debugging of RL78 MCUs during firmware development, production validation, and failure analysis - especially where signal integrity, thermal stability, and repeatable socket engagement are critical.

Technical Context

The QB-80FB-NQ-01T implements a passive, impedance-matched signal routing path between the IECUBE main unit's NQ interface and the target RL78 MCU's debug pins (TRST, TCK, TMS, TDI, TDO, RESET, VDD, VSS). It complies with IEEE 1149.1 JTAG and ARM Serial Wire Debug (SWD) timing requirements for RL78 devices operating up to 20 MHz debug clock frequency.

It is mechanically engineered for precise alignment with 80-pin LQFP packages measuring 12 mm × 12 mm × 1.4 mm (0.5 mm pitch), featuring gold-plated beryllium copper contact fingers, integrated strain relief, and a low-profile ZIF-style actuation mechanism compatible with Tokyo Eletech's NQPACK080SD-ND socket assembly.

FAQ

What is the QB-80FB-NQ-01T used for?

The QB-80FB-NQ-01T is a target connector adapter that bridges the Renesas IECUBE emulator to 80-pin LQFP-packaged RL78 microcontrollers. It enables full JTAG/SWD debugging, flash programming, and real-time trace capture for devices such as the R5F10FME and R5F10DPL. The QB-80FB-NQ-01T ensures signal fidelity and mechanical repeatability during iterative firmware development and production test.

Is QB-80FB-NQ-01T compatible with QB-80GK-NQ-01T?

Yes - QB-80FB-NQ-01T and QB-80GK-NQ-01T are functionally identical parts; the latter is the legacy part number listed in parentheses in official documentation. Both refer to the same NQ-interface adapter for 80-pin RL78 LQFP targets, with no electrical, mechanical, or firmware differences. The QB-80FB-NQ-01T is the current orderable designation.

Which socket does QB-80FB-NQ-01T require?

The QB-80FB-NQ-01T is designed to mate exclusively with the NQPACK080SD-ND socket assembly manufactured by Tokyo Eletech Corporation. This socket provides zero-insertion-force (ZIF) contact, thermal stability up to 70 °C, and precise alignment for 0.5 mm pitch 80-pin LQFP packages. Use of alternate sockets may compromise signal integrity or mechanical retention.

Can QB-80FB-NQ-01T be used with non-RL78 targets?

No - the QB-80FB-NQ-01T is specifically calibrated for Renesas RL78 family debug pinouts, voltage levels (3.3 V I/O), and timing margins. Its pin mapping, trace lengths, and termination match only RL78 80-pin LQFP variants (e.g., R5F10FME, R5F10DPL). It is not interoperable with RX, RA, or third-party MCUs, even if package dimensions appear similar.

Does QB-80FB-NQ-01T support SWO trace output?

No - the QB-80FB-NQ-01T provides only standard JTAG and SWD signals (TCK, TMS, TDI, TDO, TRST, RESET, VDD, VSS). It does not route or condition the Serial Wire Output (SWO) signal required for printf-style trace streaming. For SWO-capable debugging, Renesas recommends the QB-80FB-YQ-01T (YQ-series) adapter paired with a YQPACK080SD socket.
