Renesas QB-36LA-NQ-01T

Overview

QB-36LA-NQ-01T from Renesas Electronics is a target connector designed for use with the QB-RL78G1F in-circuit emulator to interface with RL78/G1F microcontrollers in 36-pin LGA (Land Grid Array) packages. It provides mechanical and electrical connection between the emulator's YQ connector and the target board, supporting debug signals including trace, reset, clock, and power monitoring. It enables real-time execution, memory/register manipulation, and trace capture during embedded firmware development.

For engineers reviewing the QB-36LA-NQ-01T datasheet, QB-36LA-NQ-01T pinout, QB-36LA-NQ-01T application, or QB-36LA-NQ-01T equivalent, this component is essential for establishing reliable physical debug connectivity to RL78/G1F-based systems - particularly where space-constrained LGA packaging requires precise alignment and low-profile mounting without soldering.

Technical Context

The QB-36LA-NQ-01T is a passive, unpowered mechanical interface component used exclusively within the QB-RL78G1F emulation ecosystem. It mates directly with the QB-36LA-EA-02T exchange adapter and connects to the target PCB via surface-mount land pattern matching the RL78/G1F 36LA package footprint. Its design supports high-fidelity signal integrity for JTAG/E1 debug interface lines, trace clock (TRCLK), and trace data (TRD0–TRD3) required for real-time instruction tracing up to 120 MHz.

No active circuitry, voltage regulation, or logic translation is present. All electrical characteristics - including impedance control, contact resistance (<50 mΩ), and current rating per pin (≤100 mA) - are defined by Renesas' mechanical specification and validated against IECUBE system-level timing requirements. It operates only within the 0°C to +40°C ambient range and requires GND continuity between emulator and target to prevent signal corruption.

FAQ

What is the primary function of the QB-36LA-NQ-01T in the QB-RL78G1F emulation system?

The QB-36LA-NQ-01T serves as the target-side surface-mount connector that physically interfaces the QB-RL78G1F in-circuit emulator with an RL78/G1F microcontroller in a 36-pin LGA package. It provides precise, repeatable electrical connection for JTAG/E1 debugging, trace signal routing, and power monitoring - enabling real-time code execution analysis without soldering or socketing the MCU.

Is QB-36LA-NQ-01T compatible with any other Renesas emulators besides QB-RL78G1F?

No - QB-36LA-NQ-01T is explicitly designated for use with the QB-RL78G1F in-circuit emulator and its associated adapter stack (QB-36LA-EA-02T exchange adapter and QB-36LA-YQ-01T YQ connector). It is not mechanically or electrically compatible with older E1/E20 emulators or newer CS+ debug tools, as pinout, spacing, and signal routing are specific to the IECUBE RL78/G1F configuration.

Does QB-36LA-NQ-01T require external power or configuration?

No - QB-36LA-NQ-01T is a passive, unpowered interconnect component. It contains no active circuitry, firmware, or configuration settings. Power and signal conditioning are handled entirely by the QB-RL78G1F emulator unit and the target system; the QB-36LA-NQ-01T functions solely as a precision-machined conductive bridge between them.

Can QB-36LA-NQ-01T be used on a production PCB, or is it only for development?

QB-36LA-NQ-01T is intended strictly for development and debug use. While it can be mounted on a production PCB, Renesas does not qualify it for long-term reliability, thermal cycling, or vibration endurance in end-product deployments. Its design prioritizes ease of rework and signal fidelity during firmware bring-up - not field longevity or environmental robustness.

What mechanical accessories must be used with QB-36LA-NQ-01T to complete the debug chain?

To establish full debug functionality, QB-36LA-NQ-01T must be used with the QB-36LA-EA-02T exchange adapter (which converts to the emulator's standard interface), the QB-36LA-YQ-01T YQ connector (which links EA to the QB-RL78G1F unit), and the QB-RL78G1F emulator itself. No additional probes or adapters are required for basic JTAG/E1 operation, though optional check-pin adapters may be added for waveform monitoring.
