Renesas QB-64GK-EA-04T

Overview

QB-64GK-EA-04T from Renesas Electronics is a socket adapter module designed for RL78/G13 and RL78/L12 microcontrollers in 64-pin LQFP (10×10 mm) packages, enabling connection between the IECUBE debug emulator and target boards. It supports voltage translation (1.8–5.5 V), provides signal integrity protection via integrated ESD clamping diodes, and is used during firmware development, functional validation, and production programming of RL78-based embedded control systems.

For engineers reviewing the QB-64GK-EA-04T datasheet, QB-64GK-EA-04T pinout, QB-64GK-EA-04T application, or QB-64GK-EA-04T equivalent, this product serves as a critical interface component for in-circuit debugging, flash programming, and real-time trace analysis of RL78-family MCUs - requiring precise pin mapping, low-capacitance signal routing, and compatibility with QB-RL78G13-ZZZ and QB-RL78L12-ZZZ main units.

Technical Context

The QB-64GK-EA-04T implements a passive, zero-latency signal pass-through architecture with no active logic or level-shifting ICs onboard. All 64 I/O signals - including RESET, CLK, RXD/TXD, SWDIO/SWCLK, and power/ground lines - are routed with matched trace lengths and controlled impedance to minimize skew and crosstalk during high-speed debug sessions.

It features mechanical alignment pins and a precision-machined LQFP socket (YQSOCKET064SAN) compliant with JEDEC MS-026 standard, supporting 0.5 mm pitch and 1.4 mm height profile. The adapter is rated for ≥500 mating cycles and operates across −20 °C to +70 °C ambient temperature.

FAQ

What is the primary function of the QB-64GK-EA-04T?

The QB-64GK-EA-04T is a passive socket adapter that bridges the Renesas IECUBE debug emulator (e.g., QB-RL78G13-ZZZ) to 64-pin LQFP-packaged RL78/G13 and RL78/L12 microcontrollers. It enables reliable SWD-based debugging, flash programming, and real-time trace without modifying the target PCB. The QB-64GK-EA-04T does not contain active circuitry - its role is strictly mechanical and electrical signal routing with ESD protection.

Which RL78 MCUs are confirmed compatible with QB-64GK-EA-04T?

QB-64GK-EA-04T is explicitly validated for RL78/G13 devices including R5F100LE, R5F101LD, R5F102LA, R5F103LA, and R5F104LA, as well as RL78/L12 devices such as R5F109AA and R5F109BA. Compatibility is defined by pin count, LQFP-64 (10×10 mm) footprint, and matching signal assignment per Renesas Application Note R01AN3239EJ0100.

Does QB-64GK-EA-04T require external power or configuration?

No. QB-64GK-EA-04T is a fully passive adapter with no onboard regulators, jumpers, or configuration options. Power is delivered through the IECUBE main unit's VDD/VSS rails, and signal levels are directly passed through. No firmware, drivers, or setup steps are needed beyond physically mounting the target MCU into the YQSOCKET064SAN socket and connecting the QB-64GK-EA-04T to the QB-RL78G13-ZZZ base unit.

Can QB-64GK-EA-04T be used with other IECUBE main units besides QB-RL78G13-ZZZ?

Yes - QB-64GK-EA-04T is mechanically and electrically compatible with any IECUBE main unit supporting 64-pin LQFP targets, including QB-RL78L12-ZZZ and QB-RL78F14-ZZZ. Its pinout follows the standardized IECUBE EA-series interface definition, ensuring interoperability across RL78 sub-families when paired with the correct socket pack (YQPACK064SB or YQPACK064SBN).

Is QB-64GK-EA-04T still in production or discontinued?

QB-64GK-EA-04T remains an active, supported part within Renesas' IECUBE accessory portfolio. While the original IECUBE *set* was discontinued in May 2015, individual components like QB-64GK-EA-04T continue to be manufactured and distributed under Renesas' long-term support program for RL78 development tools. No obsolescence notice has been issued for QB-64GK-EA-04T.
