Renesas QB-64GC-YQ-01T

Overview

QB-64GC-YQ-01T from Renesas Electronics is a YQ-series target connector adapter designed for RL78 family microcontrollers, supporting 64-pin FBGA (4×4 mm) packaged devices including R5F10CGD, R5F10DGE, and R5F10DLD. It enables high-fidelity debug and emulation via IECUBE main unit with YQ interface, delivering stable signal integrity for flash programming and real-time trace.

For engineers reviewing the QB-64GC-YQ-01T datasheet, QB-64GC-YQ-01T pinout, QB-64GC-YQ-01T application, or QB-64GC-YQ-01T equivalent, this adapter provides verified mechanical and electrical compatibility with RL78-based target boards using YQ Connector interface, precise pitch alignment for 64-pin FBGA, and drop-in integration into existing IECUBE development workflows.

Technical Context

The QB-64GC-YQ-01T serves as a physical interface bridge between the IECUBE emulation probe and RL78 MCUs in 64-pin FBGA packages. It implements direct pin-mapped routing without signal conditioning or level translation, preserving native timing and voltage domains of the RL78 debug interface (SWD/JTAG).

It is mechanically engineered to match the 0.4 mm pitch and 4×4 mm footprint of supported FBGA devices, and electrically validated for ≤100 MHz debug clock operation. The adapter requires pairing with QB-64GB-YQ-01T (listed as functional equivalent in documentation) and YQSOCKET064SDN socket for full system operation.

FAQ

What is the primary function of the QB-64GC-YQ-01T?

The QB-64GC-YQ-01T is a target connector adapter that enables physical and electrical interfacing between the IECUBE emulation probe and RL78 microcontrollers housed in 64-pin FBGA packages. It ensures reliable SWD/JTAG signal transmission during debug, flash programming, and real-time trace operations - a critical link in the QB-64GC-YQ-01T-based development workflow.

Which RL78 devices are explicitly supported by the QB-64GC-YQ-01T?

The QB-64GC-YQ-01T supports RL78 devices listed under QB-RL78D1A-ZZZ and QB-RL78D1A2-ZZZ, including R5F10CGD, R5F10DGE, R5F10DLD, R5F10DME, R5F10DMF, R5F10TPJ, R5F10DPG, R5F10DPL, R5F10DPK, R5F10DSL, R5F10DSK, and R5F10DSJ - all in compatible 64-pin FBGA packaging.

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

No - the QB-64GC-YQ-01T is exclusively designed for the YQ interface variant of the IECUBE system. It is not electrically or mechanically compatible with NQ, HQ, or YS variants. Using it with non-YQ main units or probes may result in connection failure or signal integrity issues.

Does the QB-64GC-YQ-01T require additional components to operate?

Yes - the QB-64GC-YQ-01T must be used with the YQSOCKET064SDN socket (manufactured by Tokyo Eletech Corporation) to securely mount the target RL78 FBGA device, and paired with an IECUBE main unit bearing the YQ interface (e.g., QB-64GB-YQ-01T) to complete the emulation chain.

Is QB-64GC-YQ-01T still in active production or discontinued?

The QB-64GC-YQ-01T remains an active, orderable part per Renesas' official optional product list for IECUBE. While the full IECUBE *set* was discontinued in May 2015, individual components including QB-64GC-YQ-01T continue to be available for separate purchase to support legacy and ongoing RL78 development.
