Renesas QB-32FP-NQ-01T

Overview

QB-32FP-NQ-01T from Renesas Electronics is a target connector designed for use with the QB-RL78L12 in-circuit emulator to interface with RL78/L12 microcontrollers in 32-pin QFP packages. It provides mechanical and electrical connection between the emulation probe (QB-80-EP-01T) and the target board, supports 1.6–5.5 V operation, enables real-time debugging via TCN1/TCN2/TCN3 signal routing, and is used in embedded firmware development for industrial control and sensor nodes.

For engineers reviewing the QB-32FP-NQ-01T datasheet, QB-32FP-NQ-01T pinout, QB-32FP-NQ-01T application, or QB-32FP-NQ-01T equivalent, this page delivers verified mechanical interface specs, T-type socket compatibility, RL78/L12-specific signal mapping, and integration guidance with QB-32FP-EA-02T exchange adapter and QB-32FP-YQ-01T YQ connector.

Technical Context

The QB-32FP-NQ-01T is a passive, surface-mount solderable connector intended exclusively for the RL78/L12 32FP package. It mates with the QB-32FP-YQ-01T YQ connector and interfaces directly with the QB-32FP-EA-02T exchange adapter to route debug signals (including RESET, CLK, VDD, VSS, and trace pins) from the QB-RL78L12 emulator to the target device.

It forms part of a T-type socket-based emulation chain requiring precise height alignment using QB-32FP-YS-01T space adapter. Signal integrity is maintained through controlled impedance routing optimized for high-speed debug clock (up to 24 MHz) and real-time trace data capture at 120 MHz sampling rate.

FAQ

What is the primary function of QB-32FP-NQ-01T in the QB-RL78L12 emulation system?

QB-32FP-NQ-01T serves as the target-side soldered connector that mechanically and electrically interfaces the QB-RL78L12 in-circuit emulator with an RL78/L12 microcontroller in a 32-pin QFP package. It routes debug signals-including RESET, CLK, VDD, VSS, and trace I/O-from the emulator through the QB-32FP-YQ-01T and QB-32FP-EA-02T adapters to the target board, enabling real-time firmware debugging without requiring socketed ICs. QB-32FP-NQ-01T is essential for stable, repeatable debug sessions in prototype and pre-production hardware.

Which RL78/L12 package variants is QB-32FP-NQ-01T compatible with?

QB-32FP-NQ-01T is explicitly designed for the RL78/L12 in the 32-pin QFP (32FP) package only. It is not compatible with other RL78/L12 packages such as 44FP, 48FB, or 64FA. The part number encoding ("32FP") and documentation in Table 1-3 of the QB-RL78L12 User's Manual confirm this exclusive mapping. Using QB-32FP-NQ-01T with any non-32FP package risks misalignment, incomplete signal routing, or physical damage to the connector or target PCB.

Does QB-32FP-NQ-01T require additional adapters to work with QB-RL78L12?

Yes, QB-32FP-NQ-01T requires two mandatory adapters to complete the debug chain: QB-32FP-YQ-01T (YQ connector) and QB-32FP-EA-02T (exchange adapter). These are listed as included components in the QB-RL78L12-32FP kit and are necessary to bridge signal paths from the QB-RL78L12 main unit to the target board. QB-32FP-NQ-01T alone cannot connect directly to the emulator - it must be used in conjunction with those adapters to ensure correct pin mapping and mechanical registration.

Can QB-32FP-NQ-01T be used with non-Renesas debug tools?

No, QB-32FP-NQ-01T is a proprietary mechanical and signal interface component designed exclusively for use with Renesas' QB-RL78L12 in-circuit emulator and its associated adapter ecosystem. Its pinout, signal assignment, and mechanical tolerances are optimized for Renesas' IECUBE™ architecture and are not documented for third-party tool compatibility. There is no evidence in official documentation or distributor listings supporting interoperability with non-Renesas emulators or debug probes.

Is QB-32FP-NQ-01T RoHS compliant and lead-free?

Yes, QB-32FP-NQ-01T complies with the EU RoHS Directive, as confirmed by Renesas Electronics' environmental compliance statements in the QB-RL78L12 User's Manual and public product declarations. It is manufactured using lead-free solderable terminations and contains no restricted substances above threshold limits. This compliance applies to both the connector body and plated contact surfaces, ensuring suitability for modern electronics assembly processes requiring RoHS-conformant components like QB-32FP-NQ-01T.
