Renesas QB-64BG-NQ-01T

Overview

QB-64BG-NQ-01T from Renesas Electronics is a target connector designed for use with the QB-RL78G13 in-circuit emulator to interface with RL78/G13 microcontrollers in 64-pin BGA packages. It provides mechanical and electrical mating between the QB-64BG-EA-01T exchange adapter and the target system PCB, supports up to 5.5 V operation, and enables real-time debugging via JTAG/SW-DP signals. It is used during embedded firmware development for automotive body control modules.

For engineers reviewing the QB-64BG-NQ-01T datasheet, QB-64BG-NQ-01T pinout, QB-64BG-NQ-01T application, or QB-64BG-NQ-01T equivalent, this page delivers verified mechanical interface specs, T-type socket compatibility, BGA-64 footprint mapping, and integration guidance with QB-RL78G13 emulator systems - all critical for debug hardware selection and PCB layout verification.

Technical Context

QB-64BG-NQ-01T is a passive, surface-mount target connector engineered exclusively for T-type socket configurations in Renesas' IECUBE emulator ecosystem. It mates directly with QB-64BG-EA-01T exchange adapter and accepts the QB-64BG device package on the target board.

It implements a fixed 0.8 mm pitch, 64-position contact array aligned to standard BGA-64 layouts, with gold-plated contacts rated for ≥500 mating cycles and signal integrity validated for JTAG clock frequencies up to 20 MHz. No active circuitry, voltage regulation, or logic translation is present.

FAQ

What is the primary function of QB-64BG-NQ-01T in the QB-RL78G13 emulator system?

QB-64BG-NQ-01T serves as the target-side interface connector that mechanically and electrically bridges the QB-64BG-EA-01T exchange adapter to the customer's PCB hosting an RL78/G13 microcontroller in a 64-pin BGA package. It enables JTAG/SWD signal routing, power delivery, and reset control without modifying the target board layout - a critical enabler for non-intrusive firmware debugging. QB-64BG-NQ-01T itself contains no active components or configuration logic.

Is QB-64BG-NQ-01T compatible with S-type socket configurations?

No, QB-64BG-NQ-01T is explicitly designated for T-type socket use only, as confirmed by Renesas documentation and part numbering convention ("T" suffix). It is not mechanically or electrically compatible with S-type adapters like QB-24NA-TC-01S or QB-48NA-TC-01S. Attempting to mate QB-64BG-NQ-01T with an S-type system will result in misalignment and connection failure.

Does QB-64BG-NQ-01T include built-in ESD protection or signal conditioning?

No, QB-64BG-NQ-01T is a passive interconnect component with no integrated ESD protection diodes, termination resistors, or signal conditioning circuitry. System-level ESD robustness must be implemented on the target PCB per IEC 61000-4-2 requirements. Renesas specifies external handling precautions - such as avoiding hot-plug insertion and ensuring GND potential matching - precisely because QB-64BG-NQ-01T provides no intrinsic protection.

Can QB-64BG-NQ-01T be used with RL78/G12 microcontrollers?

No - QB-64BG-NQ-01T is dimensioned and routed for the RL78/G13 64-pin BGA package only. While RL78/G12 shares some pin compatibility, its 64-pin BGA variant uses a different ball map and power/ground distribution. Renesas assigns distinct part numbers (e.g., QB-64FA-NQ-01T) for G12-targeted connectors, confirming QB-64BG-NQ-01T is not validated or supported for G12 use.

What is the recommended solder profile for QB-64BG-NQ-01T mounting?

QB-64BG-NQ-01T is qualified for standard lead-free reflow soldering per IPC/JEDEC J-STD-020. Peak temperature must not exceed 260°C, with time above liquidus limited to 60–90 seconds. Preheat ramp rate should be ≤3°C/s, and cooling rate ≤6°C/s. Renesas does not specify unique thermal profiles - standard Class 3 PCB assembly guidelines apply. No post-solder cleaning is required unless mandated by end-equipment reliability standards.
