Renesas QB-64GB-EA-09T

Overview

QB-64GB-EA-09T from Renesas Electronics is a socket adapter designed for RL78 family microcontrollers in 64-pin LQFP (10×10 mm) package, enabling connection between IECUBE emulation hardware and target boards. It supports RL78/G1E, RL78/F13, and RL78/L1C MCUs, provides reliable signal integrity during debug sessions, and is compatible with YQ/NQ/HQ/YS probe interfaces.

For engineers reviewing the QB-64GB-EA-09T datasheet, QB-64GB-EA-09T pinout, QB-64GB-EA-09T application, or QB-64GB-EA-09T equivalent, this adapter enables rapid transition from development to production debugging by maintaining consistent electrical interface across RL78 64-pin LQFP variants without board redesign.

Technical Context

This adapter bridges the IECUBE main unit (e.g., QB-RL78G1E-ZZZ) to RL78 MCUs using standardized pin mapping for 64-pin LQFP packages. It preserves all debug signals including RESET, CLK, VDD, VSS, and SWD/JTAG lines per Renesas' IECUBE specification.

It is mechanically keyed to prevent misalignment and includes gold-plated contacts rated for ≥500 mating cycles. The adapter does not contain active circuitry-functionality is purely passive signal routing with impedance-controlled trace layout optimized for <100 MHz debug clock stability.

FAQ

What is the primary function of QB-64GB-EA-09T?

QB-64GB-EA-09T is a passive socket adapter that physically and electrically connects Renesas IECUBE emulation hardware to target boards hosting RL78 microcontrollers in 64-pin LQFP (10×10 mm) packages. It routes debug signals-including RESET, CLK, SWDIO, SWCLK, VDD, and VSS-without signal conditioning or level translation. QB-64GB-EA-09T ensures mechanical alignment and contact reliability during repeated debug sessions.

Which RL78 microcontroller variants are confirmed compatible with QB-64GB-EA-09T?

QB-64GB-EA-09T is explicitly listed in Renesas' IECUBE optional product list for RL78/G1E, RL78/F13, and RL78/L1C families. It supports devices such as R5F10FME (G1E), R5F10PLD (F13), and R5F10MMG (L1C), all packaged in 64-pin LQFP (10×10 mm). Compatibility is defined by pin count, pitch, and debug signal assignment-not by internal MCU architecture.

Does QB-64GB-EA-09T require external power or configuration?

No. QB-64GB-EA-09T is a fully passive adapter with no active components, power input, or configuration interface. It draws no current and requires no firmware, jumpers, or DIP switches. Power for the target MCU is supplied either through the IECUBE unit (if enabled) or externally via the target board - QB-64GB-EA-09T only routes existing voltage and signal lines.

Can QB-64GB-EA-09T be used with non-Renesas debug tools?

No. QB-64GB-EA-09T is mechanically and electrically designed exclusively for Renesas IECUBE systems (e.g., QB-RL78G1E-ZZZ main units) and their proprietary YQ/NQ/HQ/YS probe interfaces. Its pinout, footprint, and signal mapping do not conform to generic JTAG adapters or third-party emulators like Segger J-Link or ST-LINK.

Is QB-64GB-EA-09T still in active production and supported by Renesas?

Yes. Although Renesas discontinued the full IECUBE *set* in May 2015, QB-64GB-EA-09T remains an active, orderable part within the IECUBE accessory portfolio. Renesas continues to publish user manuals and support documentation for QB-64GB-EA-09T, confirming its ongoing availability and technical support for RL78 development workflows.
