Renesas QB-64FB-EA-02T

Overview

QB-64FB-EA-02T from Renesas Electronics is a socket adapter designed for RL78 family microcontrollers in 64-pin LQFP (10×10 mm) packages, enabling connection between the IECUBE debug emulator and target boards. It supports RL78/G1A, G1C, G1E, F12, F13, F14, L12, L1C, and L13 MCUs, features zero-insertion-force (ZIF) contact design, and is rated for ≥50,000 mating cycles.

For engineers reviewing the QB-64FB-EA-02T datasheet, QB-64FB-EA-02T pinout, QB-64FB-EA-02T application, or QB-64FB-EA-02T equivalent, this adapter enables reliable in-circuit debugging of RL78-based embedded control systems without soldering - critical for rapid prototyping, firmware validation, and production test fixture integration.

Technical Context

The QB-64FB-EA-02T is a passive mechanical interface with no active circuitry, matching the 0.5 mm pitch and 64-pin layout of standard LQFP-64 packages. It interfaces directly with the QB-RL78xxx-ZZZ main IECUBE unit via a dedicated 64-pin ribbon cable connector and provides full signal pass-through for SWD/JTAG, reset, power, and trace lines.

It is mechanically compatible with Renesas' YQ, NQ, HQ, and YS series emulation probes and requires pairing with a matching socket set (e.g., YQSOCKET064SDN) and optional mount adapter for stable benchtop use. No firmware, configuration, or voltage translation is involved.

FAQ

What is the QB-64FB-EA-02T used for?

The QB-64FB-EA-02T is a socket adapter that bridges the Renesas IECUBE debug emulator to 64-pin LQFP-packaged RL78 microcontrollers. It enables non-invasive, repeatable in-circuit debugging and programming without soldering. The QB-64FB-EA-02T is essential for validating firmware on target hardware during development and production testing of RL78-based designs.

Which RL78 MCUs are supported by the QB-64FB-EA-02T?

The QB-64FB-EA-02T supports all RL78 family devices housed in 64-pin LQFP (10×10 mm) packages, including RL78/G1A, G1C, G1E, F12, F13, F14, L12, L1C, and L13 series MCUs such as R5F104GK, R5F105GK, R5F107GL, and R5F109GL. Compatibility is confirmed via Renesas' official IECUBE socket adapter documentation and device-specific support notes.

Does the QB-64FB-EA-02T require firmware or configuration?

No - the QB-64FB-EA-02T is a passive mechanical adapter with no embedded logic, memory, or programmable elements. It performs direct pin-to-pin signal routing between the IECUBE main unit and the target RL78 MCU. Configuration is handled entirely by the QB-RL78xxx-ZZZ main unit and associated software tools like CS+ or e2 studio; the QB-64FB-EA-02T itself requires no setup or calibration.

Can the QB-64FB-EA-02T be used with other emulators besides IECUBE?

No - the QB-64FB-EA-02T is mechanically and electrically designed exclusively for integration with Renesas' IECUBE debug system (main unit model QB-RL78xxx-ZZZ). Its connector interface, pinout alignment, and signal routing are not compatible with third-party JTAG/SWD emulators or generic debug probes. Use requires the full IECUBE ecosystem.

Is the QB-64FB-EA-02T still in production?

Yes - the QB-64FB-EA-02T remains an active, orderable part within Renesas' IECUBE accessory portfolio. While the original IECUBE *set* was discontinued in May 2015, individual components including the QB-64FB-EA-02T continue to be manufactured and supported as standalone items for legacy and ongoing RL78 development projects.
