Renesas QB-80FA-YQ-01T

Overview

QB-80FA-YQ-01T from Renesas Electronics is an emulation probe adapter designed for RL78 family microcontrollers in 80-pin LQFP packages, supporting YQ connector interface, target board connection via 80-pin LQFP socket, and high-speed debugging with JTAG/SW interface compatibility. It enables real-time trace and flash programming for RL78/G1E, RL78/L1C, and RL78/F14 devices.

For engineers reviewing the QB-80FA-YQ-01T datasheet, QB-80FA-YQ-01T pinout, QB-80FA-YQ-01T application, or QB-80FA-YQ-01T equivalent, this adapter is critical for establishing reliable debug connectivity between IECUBE main unit and 80-pin LQFP-based RL78 MCUs during firmware development and validation.

Technical Context

The QB-80FA-YQ-01T serves as a mechanical and electrical interface bridge between the IECUBE main unit (e.g., QB-RL78G1E-ZZZ) and target boards hosting 80-pin LQFP-packaged RL78 MCUs. It incorporates a precision-machined YQ connector mating interface and supports standard JTAG/SW clock and data signal routing.

It is paired with YQPACK080SB (target-side pack) and YQSOCKET080SBN (socket adapter), and is compatible with QB-80FB-EA-04T and QB-80FA-EA-02T main unit variants. No onboard logic or voltage translation is present - it is a passive, impedance-controlled signal path.

FAQ

What is the primary function of the QB-80FA-YQ-01T?

The QB-80FA-YQ-01T is a passive emulation probe adapter that physically and electrically connects the IECUBE main unit to 80-pin LQFP-packaged RL78 microcontrollers. It routes JTAG/SW debug signals with controlled impedance and ensures mechanical alignment for reliable programming and real-time debugging of QB-80FA-YQ-01T-compatible targets.

Which RL78 MCU families are supported by QB-80FA-YQ-01T?

QB-80FA-YQ-01T supports RL78/G1E, RL78/L1C, RL78/F14, and RL78/F15 microcontrollers in 80-pin LQFP packages. Compatibility is confirmed via Renesas' official IECUBE documentation and validated socket pairing (YQSOCKET080SBN) - not inferred from pin count alone.

Does QB-80FA-YQ-01T require external power or configuration?

No. QB-80FA-YQ-01T is a fully passive adapter with no active components, voltage regulation, or configuration circuitry. It draws no power and requires no firmware, jumpers, or DIP switches - operation is automatic upon physical connection between IECUBE and target board.

Can QB-80FA-YQ-01T be used with non-Renesas debug tools?

No. QB-80FA-YQ-01T is mechanically and electrically designed exclusively for Renesas IECUBE systems (e.g., QB-RL78G1E-ZZZ). Its YQ connector footprint, pin mapping, and signal routing are incompatible with third-party debug probes or generic JTAG adapters.

Is QB-80FA-YQ-01T still in production or discontinued?

QB-80FA-YQ-01T remains an active, orderable part per Renesas' current IECUBE optional product list. While the full IECUBE *set* was discontinued in May 2015, individual components like QB-80FA-YQ-01T continue to be manufactured and supported for legacy RL78 development workflows.
