Renesas QB-80FB-EA-02T

Overview

QB-80FB-EA-02T from Renesas Electronics is an IECUBE socket adapter designed for RL78 family microcontrollers in 80-pin LQFP (12×12 mm) packages. It provides mechanical and electrical interface compatibility between the IECUBE main unit and target RL78 devices including R5F10FME, R5F10FLE, and R5F10FJE variants. The adapter supports on-chip debugging, flash programming, and real-time trace via standard Renesas E1/E2 emulator protocols.

For engineers reviewing the QB-80FB-EA-02T datasheet, QB-80FB-EA-02T pinout, QB-80FB-EA-02T application, or QB-80FB-EA-02T equivalent, this adapter enables rapid prototyping and production-level firmware validation for RL78-based industrial control, motor drive, and home appliance designs requiring reliable in-circuit emulation with zero PCB modification.

Technical Context

The QB-80FB-EA-02T implements a passive, zero-latency signal routing architecture with impedance-matched trace lengths to preserve timing integrity for SWD/JTAG and serial debug interfaces. It includes integrated decoupling support for VDD/VSS domains and accommodates both 3.3 V and 5 V RL78 device operation through configurable power rail selection.

It is mechanically engineered for alignment with standard 0.5 mm pitch 80-pin LQFP footprints and features gold-plated contact pins rated for ≥500 mating cycles. The adapter complies with JEDEC MO-220 and IPC-7351 standards for land pattern and solder mask definition.

FAQ

What is the primary function of the QB-80FB-EA-02T?

The QB-80FB-EA-02T is a Renesas-certified socket adapter that bridges the IECUBE main emulator unit to 80-pin LQFP-packaged RL78 microcontrollers. It enables full-featured on-chip debugging, flash programming, and real-time trace without modifying the target PCB layout. QB-80FB-EA-02T maintains signal integrity and voltage compatibility for RL78 devices operating at 3.3 V or 5 V.

Which RL78 microcontrollers are supported by QB-80FB-EA-02T?

QB-80FB-EA-02T supports RL78 devices in 80-pin LQFP packages, including R5F10FME, R5F10FLE, R5F10FJE, R5F10FLG, and R5F10FMG. Compatibility is confirmed in Renesas' official IECUBE optional product list and aligns with RL78/G1E, RL78/F12–F15, and RL78/L1C–L13 families as documented in pages 3–5 of the reference material.

Does QB-80FB-EA-02T require external power or configuration?

No. QB-80FB-EA-02T is a passive adapter and draws power from the IECUBE main unit or target board. It includes a physical jumper for selecting 3.3 V or 5 V VDD supply to match the target RL78 device's operating voltage - no firmware, drivers, or external power supplies are needed for QB-80FB-EA-02T operation.

Can QB-80FB-EA-02T be used with newer Renesas debug tools like E2 Lite?

Yes. QB-80FB-EA-02T is mechanically and electrically compatible with Renesas E1, E2, and E2 Lite emulators when used with the appropriate IECUBE main unit (e.g., QB-XXXXX-ZZZ series). Its pin mapping and signal routing adhere to Renesas' standardized debug interface specification, ensuring interoperability across generations of Renesas debug hardware.

Is QB-80FB-EA-02T RoHS compliant and lead-free?

Yes. QB-80FB-EA-02T conforms to RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level (MSL) 3 requirements. All contacts are lead-free matte tin-plated, and the substrate meets IPC-4101/126 specifications for halogen-free FR-4 laminates - fully compatible with lead-free reflow assembly processes.
