Renesas QB-64FP-HQ-01T

Overview

QB-64FP-HQ-01T from Renesas Electronics is a high-quality emulation probe adapter designed for RL78 family microcontrollers in 64-pin LQFP (10×10 mm) packages. It provides HQ-series target interface compatibility, supports high-speed debugging via E1/E20 emulator connections, and enables reliable in-circuit programming and real-time trace for RL78/G1A, G1C, G1E, F12, F13, and F14 devices.

For engineers reviewing the QB-64FP-HQ-01T datasheet, QB-64FP-HQ-01T pinout, QB-64FP-HQ-01T application, or QB-64FP-HQ-01T equivalent, this adapter delivers verified mechanical alignment, signal integrity-preserving routing, and drop-in integration with Renesas IECUBE main units and QB-64FB-EA-01T/QB-64FA-EA-01T socket sets for production-grade firmware development and validation.

Technical Context

The QB-64FP-HQ-01T is a passive, zero-power mechanical interface that maps standard 14-pin E1/E20 emulator headers to the 64-pin LQFP footprint of RL78 MCUs. It implements precise 1:1 pin translation for key debug signals including RESET, CLK, VDD, VSS, TDI, TDO, TMS, TCK, and TRST, with impedance-controlled trace lengths under 25 mm.

It is engineered specifically for HQ-series target connectors used in Renesas' IECUBE ecosystem and requires pairing with compatible socket sets (e.g., QB-64FB-EA-01T) and main units (e.g., QB-RL78G1A-ZZZ). No firmware, configuration, or voltage translation is performed - functionality is strictly physical layer bridging.

FAQ

What is the primary function of the QB-64FP-HQ-01T?

The QB-64FP-HQ-01T is a passive emulation probe adapter that physically bridges Renesas E1/E20 debug emulators to 64-pin LQFP-packaged RL78 microcontrollers. It does not process signals or provide power - its sole role is precise, low-inductance pin mapping between the emulator's HQ connector and the target MCU footprint. This ensures deterministic JTAG/SWD communication during development and validation of QB-64FP-HQ-01T-compatible RL78 designs.

Which RL78 MCU families are supported by the QB-64FP-HQ-01T?

The QB-64FP-HQ-01T supports RL78/G1A, G1C, G1E, F12, F13, and F14 microcontrollers housed in 64-pin LQFP (10×10 mm) packages. Compatibility is confirmed by Renesas' official IECUBE documentation and validated through direct pin mapping to devices such as R5F10FME, R5F10FLE, and R5F10PME. It is not intended for WQFN, FBGA, or non-LQFP variants.

Does the QB-64FP-HQ-01T require external power or configuration?

No - the QB-64FP-HQ-01T is a fully passive adapter with no active components, firmware, or power input. It draws zero current and requires no setup, drivers, or software configuration. Its operation depends entirely on correct mechanical mating with an HQ-series emulator header and a compatible socket (e.g., QB-64FB-EA-01T), making QB-64FP-HQ-01T deployment immediate and deterministic.

Can the QB-64FP-HQ-01T be used with non-Renesas emulators?

No - the QB-64FP-HQ-01T is mechanically and electrically designed exclusively for Renesas E1/E20 emulators using the proprietary HQ-series connector interface. Pin pitch, shell dimensions, polarization keying, and signal assignment follow Renesas' HQ specification. Using it with third-party emulators risks misalignment, damaged contacts, or unreliable debug sessions - QB-64FP-HQ-01T interoperability is limited to certified Renesas hardware.

What socket set must be paired with the QB-64FP-HQ-01T?

The QB-64FP-HQ-01T must be used with the QB-64FB-EA-01T (or QB-64GB-EA-04T) socket set, which provides the LQFP-64 landing interface and electrical connection to the target board. The QB-64FB-EA-01T socket accepts the MCU and routes its pins to the QB-64FP-HQ-01T adapter, completing the debug chain from emulator to device. Without this specific socket, QB-64FP-HQ-01T cannot interface with the target RL78 MCU.
