Renesas QB-80FB-EA-06T

Overview

QB-80FB-EA-06T from Renesas Electronics is an IECUBE socket adapter designed for RL78/L1C microcontrollers in 80-pin LQFP (12×12 mm) packages. It enables in-circuit emulation and debug connection between the IECUBE main unit and target RL78/L1C devices, supporting JTAG/SWJ interface protocols and operating at 3.3 V supply. It is used in firmware development, validation, and production programming of RL78-based industrial control and sensor nodes.

For engineers reviewing the QB-80FB-EA-06T datasheet, QB-80FB-EA-06T pinout, QB-80FB-EA-06T application, or QB-80FB-EA-06T equivalent, this adapter provides verified mechanical and electrical compatibility with Renesas' RL78/L1C family, ensures signal integrity for high-speed debug clock (up to 10 MHz), and integrates ESD protection on all critical debug lines per IEC 61000-4-2 Level 3.

Technical Context

The QB-80FB-EA-06T is a passive, zero-power socket adapter that maps the 80-pin LQFP footprint of RL78/L1C MCUs to the standard IECUBE target connector interface. It maintains strict 50 Ω characteristic impedance on TCK/TMS/TDO/TDI traces and supports both JTAG and Serial Wire Debug (SWD) modes without external configuration.

It is mechanically keyed to prevent misalignment during insertion and features gold-plated contact pins rated for ≥500 mating cycles. The adapter complies with RoHS Directive 2011/65/EU and operates within −20 °C to +70 °C ambient temperature range.

FAQ

What is the primary function of the QB-80FB-EA-06T?

The QB-80FB-EA-06T is a socket adapter that physically and electrically interfaces Renesas RL78/L1C microcontrollers in 80-pin LQFP packages with the IECUBE main emulator unit. It enables reliable JTAG/SWD communication for debugging, flash programming, and real-time trace - and is required when using the IECUBE system with RL78/L1C devices. QB-80FB-EA-06T does not contain active circuitry and requires no firmware or drivers.

Which RL78 microcontrollers are supported by QB-80FB-EA-06T?

QB-80FB-EA-06T is specifically qualified for the RL78/L1C family, including part numbers such as R5F11LBC, R5F11LBE, and R5F11LBF. It is not compatible with RL78/G1x, F1x, or I1x families - those require distinct adapters like QB-80FB-EA-01T or QB-80FB-EA-04T. Compatibility is defined by pin count, package dimensions, and debug signal routing per Renesas' IECUBE documentation.

Does QB-80FB-EA-06T require external power or configuration?

No, QB-80FB-EA-06T is a passive adapter with no onboard power regulation, voltage translation, or configuration logic. It receives 3.3 V power and debug signals directly from the IECUBE main unit via its standardized target connector. No jumpers, DIP switches, or software setup are needed - correct mechanical alignment and firm seating ensure functional operation of QB-80FB-EA-06T.

Can QB-80FB-EA-06T be used with third-party debuggers?

No - QB-80FB-EA-06T is mechanically and electrically designed exclusively for Renesas' IECUBE main unit (e.g., QB-RL78L1C-ZZZ). Its pinout, connector type (2×20 female header), and signal mapping do not conform to ARM CMSIS-DAP, Segger J-Link, or ST-LINK standards. Using QB-80FB-EA-06T with non-IECUBE debuggers will result in physical incompatibility and signal misalignment.

Is QB-80FB-EA-06T still in production and supported by Renesas?

Yes, QB-80FB-EA-06T remains an active, orderable part under Renesas' IECUBE accessory portfolio. It is listed in current Renesas ordering documents and supported with user manuals, mechanical drawings, and compatibility matrices for RL78/L1C devices. Discontinued variants (e.g., *1 suffix) are explicitly marked - QB-80FB-EA-06T carries no discontinuation flag and is fully supported for new designs.
