Renesas QB-100GC-YQ-01T

Overview

QB-100GC-YQ-01T from Renesas Electronics is a YQ-series connector used to interface the QB-78K0RFX3 in-circuit emulator with 100-pin LQFP-packaged 78K0R/FX3 and 78K0R/HX3 microcontrollers (e.g., 78K0R/FG3, 78K0R/HG3). It mates with QB-100GC-NQ-01T target connector and QB-100GC-EA-09T exchange adapter, supports 2.7–5.5 V operation, and enables real-time debugging via USB host interface.

For engineers reviewing the QB-100GC-YQ-01T datasheet, QB-100GC-YQ-01T pinout, QB-100GC-YQ-01T application, or QB-100GC-YQ-01T equivalent, this page delivers verified mechanical interface specifications, mating compatibility details, handling precautions for high-reliability debug setups, and OEM supply support for embedded development programs targeting Renesas 78K0R microcontrollers.

Technical Context

The QB-100GC-YQ-01T is a rigid, precision-machined board-to-board connector designed exclusively for the QB-78K0RFX3 emulation system. It provides 100-position signal routing between the QB-100GC-EA-09T exchange adapter and QB-100GC-NQ-01T target connector, maintaining signal integrity for real-time trace and breakpoint functions up to 120 MHz measurement clock.

It features standardized corner-cut keying for pin-1 alignment with EA and NQ connectors, uses M2 × 10 mm mounting screws (supplied), and requires torque-limited fastening (≤0.054 Nm) to prevent contact damage. Its mechanical design accommodates height-adjustable space adapters (QB-100GC-YS-01T) for coplanarity compensation on target PCBs.

FAQ

What is the primary function of the QB-100GC-YQ-01T in the QB-78K0RFX3 emulator system?

The QB-100GC-YQ-01T serves as a dedicated 100-pin YQ-series connector that mechanically and electrically bridges the QB-100GC-EA-09T exchange adapter and QB-100GC-NQ-01T target connector. It ensures precise signal routing for real-time debugging functions-including breakpoints, trace capture, and register manipulation-between the QB-78K0RFX3 emulator and 100-pin LQFP-packaged 78K0R/FG3 or 78K0R/HG3 microcontrollers. The QB-100GC-YQ-01T is not a standalone electronic component but a critical mechanical interface element within the Renesas IECUBE ecosystem.

Which target microcontrollers and packages are compatible with QB-100GC-YQ-01T?

QB-100GC-YQ-01T is explicitly designated for use with 78K0R/FG3 and 78K0R/HG3 microcontrollers in the 100-pin LQFP package (designated "100GC" in Renesas documentation). It is listed in Table 1-3 of the QB-78K0RFX3 User's Manual as the required YQ connector for both devices and is bundled with QB-78K0RFX3-T100GC order variants. No compatibility is specified for other pin counts, packages, or device families.

Does QB-100GC-YQ-01T have electrical specifications such as voltage rating or current capacity?

No - QB-100GC-YQ-01T is a passive mechanical interconnect component without active circuitry or rated electrical parameters. Its role is purely signal routing; all electrical characteristics (e.g., 2.7–5.5 V operation, 120 MHz trace clock) are defined by the QB-78K0RFX3 emulator and target MCU. Renesas documentation specifies no voltage, current, or impedance ratings for QB-100GC-YQ-01T itself - only mechanical mating, torque limits (≤0.054 Nm), and handling precautions to preserve contact reliability.

How is QB-100GC-YQ-01T installed and secured on the target system?

QB-100GC-YQ-01T is not soldered or mounted directly to the target PCB. Instead, it is fastened between QB-100GC-NQ-01T (soldered to the target board) and QB-100GC-EA-09T (attached to the emulator) using four supplied M2 × 10 mm screws and the YQGUIDE alignment fixture. Tightening torque must not exceed 0.054 Nm to avoid damaging contacts or misalignment. Installation must occur with both emulator and target system powered off, per Section 2.3.2 of the QB-78K0RFX3 User's Manual.

Is QB-100GC-YQ-01T available as a standalone part or only in emulator kits?

QB-100GC-YQ-01T is available as a standalone orderable part (e.g., through Renesas distributors and Aetrix Electronics), not only as part of bundled kits. It is explicitly listed in Table 1-3 and Section 1.6 ("Package Contents") as included with QB-78K0RFX3-T100GC, confirming its status as a separately procurable accessory. Renesas part numbering convention (YQ-xxx) and ordering row "YQ connector QB-100GC-YQ-01T" confirm its identity as an independent connector SKU.
