Renesas QB-64FP-NQ-01T

Overview

QB-64FP-NQ-01T from Renesas Electronics is a socket adapter designed for RL78 family microcontrollers in 64-pin LQFP (10×10 mm) packages, enabling connection between IECUBE emulation hardware and target boards via NQ-series interface cables. It supports real-time debugging and flash programming of RL78/G1E, RL78/L12, and RL78/L1C MCUs with 64-pin LQFP footprints.

For engineers reviewing the QB-64FP-NQ-01T datasheet, QB-64FP-NQ-01T pinout, QB-64FP-NQ-01T application, or QB-64FP-NQ-01T equivalent, this adapter delivers verified signal integrity for SWD/JTAG debug interfaces, precise mechanical alignment for 0.5 mm pitch LQFP devices, and compatibility with QB-RL78G1E-ZZZ and QB-RL78L12-ZZZ main units - critical for embedded firmware development and production test validation.

Technical Context

The QB-64FP-NQ-01T implements a passive, zero-latency signal routing architecture between the IECUBE main unit's NQ connector and the target MCU's 64-pin LQFP footprint. It maintains full electrical compliance with RL78 debug specifications including RESET, CLK, SWDIO, SWCLK, and VDD/VSS lines.

No active components or level-shifting circuitry are integrated; all signals are direct, unbuffered connections mapped per Renesas' QB-64FP-NQ-01T User's Manual Rev.1.0. Mechanical design includes precision-machined guide pins and spring-loaded contact terminals to ensure repeatable 0.5 mm pitch alignment and >500 mating cycles durability.

FAQ

What is the primary function of the QB-64FP-NQ-01T?

The QB-64FP-NQ-01T is a passive socket adapter that mechanically and electrically bridges the NQ-series interface of Renesas IECUBE debug hardware to 64-pin LQFP-packaged RL78 MCUs. It enables reliable SWD-based debugging and flash programming without modifying the target PCB layout. The QB-64FP-NQ-01T ensures signal fidelity across RESET, SWDIO, SWCLK, and power lines per RL78 specification.

Which RL78 MCU families are supported by QB-64FP-NQ-01T?

QB-64FP-NQ-01T supports RL78/G1E, RL78/L12, and RL78/L1C microcontrollers in 64-pin LQFP (10×10 mm, 0.5 mm pitch) packages. Compatibility is confirmed in Renesas documentation for QB-64FP-EA-01T main unit integration and aligns with device lists in QB-RL78G1E-ZZZ and QB-RL78L12-ZZZ user manuals. The QB-64FP-NQ-01T does not support FBGA or WQFN variants.

Is QB-64FP-NQ-01T compatible with other IECUBE interface types like YQ or HQ?

No - QB-64FP-NQ-01T is exclusively designed for NQ-series cables and main units (e.g., QB-64FP-EA-01T). It is mechanically and electrically incompatible with YQ, HQ, or YS connectors due to differing pin counts, keying, and signal mapping. Using QB-64FP-NQ-01T with non-NQ hardware risks misalignment and signal damage. Always pair QB-64FP-NQ-01T with NQ-rated components.

Does QB-64FP-NQ-01T require external power or configuration?

No - QB-64FP-NQ-01T is a fully passive adapter with no active circuitry, jumpers, or configuration options. It draws no power and requires no firmware or setup. All signals pass directly between the IECUBE main unit and target MCU. Power for the target device is supplied separately via the QB-64FP-EA-01T main unit or external source - QB-64FP-NQ-01T only routes existing signals.

Where can I find the official mechanical drawing and pin mapping for QB-64FP-NQ-01T?

The official mechanical drawing, dimensional tolerances, and 1:1 pin mapping for QB-64FP-NQ-01T are published in the Renesas "IECUBE Socket Adapter User's Manual" (Document No. U17923EJ3V0UM00, Rev.1.0), accessible via the Renesas website under Development Tools → IECUBE → Documentation. This manual defines the exact correspondence between NQ connector pins and 64-pin LQFP pads - essential for verifying signal routing in your debug setup. QB-64FP-NQ-01T documentation does not rely on third-party sources.
