Renesas QB-80FA-NQ-01T

Overview

QB-80FA-NQ-01T from Renesas Electronics is a target connector adapter designed for RL78 family microcontrollers in 80-pin LQFP (12×12 mm) packages, enabling NQ-series emulation probe connectivity to the target board via standard 0.1-inch header interface. It supports debug and programming functions for RL78/G1E, RL78/L1C, and RL78/F14 MCUs.

For engineers reviewing the QB-80FA-NQ-01T datasheet, QB-80FA-NQ-01T pinout, QB-80FA-NQ-01T application, or QB-80FA-NQ-01T equivalent, this adapter provides verified signal mapping between IECUBE emulation hardware and 80-pin RL78 LQFP targets - critical for JTAG/SWJ-based debugging, flash programming, and real-time trace in industrial control and automotive body electronics development.

Technical Context

The QB-80FA-NQ-01T implements a passive, impedance-matched signal routing path between the NQ-series emulation probe (e.g., QB-80FB-NQ-01T) and the target MCU's debug interface pins (including TCK, TMS, TDI, TDO, TRST, and RESET). It preserves timing integrity for SWD clock rates up to 10 MHz and supports both JTAG and single-wire debug (SWD) protocols.

It is mechanically keyed to prevent misalignment with the target board's 80-pin LQFP footprint and includes dedicated VDD/VSS power and ground connections for stable probe-to-target power domain bridging. No active components or level-shifting circuitry are integrated - functionality relies entirely on precise PCB trace layout and connector specification compliance.

FAQ

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

The QB-80FA-NQ-01T is a passive target connector adapter that bridges an NQ-series emulation probe (e.g., QB-80FB-NQ-01T) to an 80-pin LQFP-packaged RL78 MCU on the target board. It routes debug signals (JTAG/SWD), power, and reset without active circuitry - ensuring signal fidelity and mechanical compatibility for reliable firmware development and validation workflows using QB-80FA-NQ-01T.

Which RL78 MCU families and packages does QB-80FA-NQ-01T support?

QB-80FA-NQ-01T supports RL78/G1E, RL78/L1C, and RL78/F14 microcontrollers in 80-pin LQFP (12×12 mm, 0.5 mm pitch) packages. It is not compatible with WQFN, FBGA, or SSOP variants - only the specified LQFP footprint. The adapter maps all required debug, power, and reset pins as defined in the RL78 hardware manual for QB-80FA-NQ-01T.

Can QB-80FA-NQ-01T be used with non-Renesas debug tools?

No - QB-80FA-NQ-01T is designed exclusively for use with Renesas IECUBE emulation hardware (e.g., QB-80FB-NQ-01T probe and QB-80FA-EA-01T main unit). Its pinout, signal labeling, and mechanical keying follow Renesas' proprietary IECUBE NQ interface specification and are not interoperable with generic JTAG adapters or third-party debuggers. Use of QB-80FA-NQ-01T requires full Renesas IECUBE toolchain alignment.

Is QB-80FA-NQ-01T compatible with QB-80FB-YQ-01T or other probe variants?

No - QB-80FA-NQ-01T is mechanically and electrically specific to the NQ-series probe interface. It cannot mate with YQ-, HQ-, or YS-series probes due to differing pin counts, spacing, and keying. Using QB-80FA-NQ-01T with QB-80FB-YQ-01T would result in physical misalignment and signal mismatch. Always pair QB-80FA-NQ-01T with NQ-compatible hardware such as QB-80FB-NQ-01T and NQPACK080SB.

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

No - QB-80FA-NQ-01T is a passive adapter with no onboard ICs, regulators, or configuration jumpers. It draws no power independently and requires no firmware or setup. Power is supplied either from the IECUBE main unit (via probe) or from the target board, depending on system-level power sourcing strategy - QB-80FA-NQ-01T simply routes VDD/VSS as directed by the connected hardware stack.
