Renesas QB-80FB-EA-03T

Overview

QB-80FB-EA-03T from Renesas Electronics is an IECUBE socket adapter designed for RL78 family microcontrollers in 80-pin LQFP (12×12 mm) packages. It enables in-circuit debugging and flash programming via the QB-RL78 main emulator unit, supporting target devices including R5F10FME, R5F10FLE, and R5F10DMD. The adapter provides mechanical alignment, signal integrity preservation, and hot-swap-safe ZIF socket interface.

For engineers reviewing the QB-80FB-EA-03T datasheet, QB-80FB-EA-03T pinout, QB-80FB-EA-03T application, or QB-80FB-EA-03T equivalent, this adapter is essential for RL78-based development workflows requiring reliable emulation connectivity, board-level debug access, and compatibility with QB-RL78D1A2 and QB-RL78G13 main units.

Technical Context

The QB-80FB-EA-03T is a passive mechanical-electrical interface that maps the 80-pin LQFP footprint of RL78 MCUs to the QB-RL78 emulator's YQ/NQ/HQ/YS probe interface standards. It supports full JTAG/SW-DP debug signaling and VDD/VSS power delivery without level translation or active logic.

It is mechanically compatible with standard 80-pin LQFP (12×12 mm, 0.5 mm pitch) packages and integrates a zero-insertion-force (ZIF) socket for repeated device insertion. No firmware, configuration, or host-side driver is required - operation is transparent to the Renesas CS+ or e² studio IDE.

FAQ

What is the primary function of the QB-80FB-EA-03T?

The QB-80FB-EA-03T is a socket adapter enabling physical and electrical connection between an RL78 microcontroller in 80-pin LQFP package and the QB-RL78 family of IECUBE emulators. It allows engineers to perform in-circuit debugging, flash programming, and real-time trace using the QB-80FB-EA-03T without soldering or permanent board modification.

Which RL78 MCUs are confirmed compatible with QB-80FB-EA-03T?

QB-80FB-EA-03T supports RL78 devices packaged in 80-pin LQFP (12×12 mm), including R5F10FME, R5F10FLE, R5F10DMD, R5F10DPJ, and all members of the RL78/G13, RL78/F13, RL78/L1C, and RL78/L13 families listed in Renesas' QB-RL78D1A2 and QB-RL78G13 documentation. Compatibility is defined by pin count, pitch, and signal assignment - not by internal MCU architecture alone.

Does QB-80FB-EA-03T require firmware or configuration?

No. QB-80FB-EA-03T is a passive hardware adapter with no embedded logic, memory, or programmable elements. It requires no firmware update, driver installation, or configuration - it functions immediately when mated with a QB-RL78 main unit and supported target board. All debug protocol handling occurs in the QB-RL78 main unit and host IDE (e.g., CS+, e² studio).

Can QB-80FB-EA-03T be used with non-Renesas debug tools?

No. QB-80FB-EA-03T is mechanically and electrically optimized exclusively for Renesas IECUBE systems - specifically the QB-RL78 main unit and its YQ/NQ/HQ/YS probe interface. It is not compatible with Segger J-Link, ST-LINK, or other third-party debug probes due to proprietary connector geometry, pinout, and signal routing.

Is QB-80FB-EA-03T still in active production?

Yes. QB-80FB-EA-03T remains an active, orderable part per Renesas' official product status documentation and distributor listings. While the full IECUBE "set" was discontinued in May 2015, individual components like QB-80FB-EA-03T continue to be manufactured and supported as standalone items for legacy and ongoing RL78 development.
