Renesas QB-44FP-EA-01T

Overview

QB-44FP-EA-01T from Renesas Electronics is an exchange adapter designed for the QB-RL78G13 in-circuit emulator, enabling physical and electrical interface conversion between the emulator's YQ connector and the target system's NQ connector for RL78/G13 44-pin QFP devices. It supports 1.6–5.5 V operation, maintains signal integrity for real-time debugging, and is used with QB-44FP-YQ-01T and QB-44FP-NQ-01T to form a complete emulation interface chain.

For engineers reviewing the QB-44FP-EA-01T datasheet, QB-44FP-EA-01T pinout, QB-44FP-EA-01T application, or QB-44FP-EA-01T equivalent, this adapter is essential when integrating the QB-RL78G13 emulator with RL78/G13-based 44-pin QFP target hardware - particularly where mechanical height adjustment (via optional YS/YQ adapters) and reliable probe-to-target signal routing are required for production-grade firmware validation.

Technical Context

The QB-44FP-EA-01T is a passive mechanical and electrical translation interface, not an active IC. It maps all 44 signal paths-including power, ground, reset, clock, and debug control lines-between the QB-RL78G13's YQ connector and the target board's NQ socket without buffering, level shifting, or timing modification. Its design assumes use within the QB-RL78G13 ecosystem and requires pairing with QB-44FP-YQ-01T (YQ side) and QB-44FP-NQ-01T (target side).

No onboard circuitry, voltage regulation, or configuration logic is present. Signal routing follows Renesas' standardized RL78/G13 emulation pin mapping, preserving trace accuracy, breakpoint reliability, and real-time RAM monitoring fidelity as defined in the QB-RL78G13 system specifications. It operates only within the 0–40°C ambient range and must be used with properly grounded, low-noise target systems to avoid emulation instability.

FAQ

What is the primary function of the QB-44FP-EA-01T in the QB-RL78G13 emulation system?

The QB-44FP-EA-01T serves as a dedicated exchange adapter that bridges the QB-RL78G13 emulator's YQ connector to the target board's NQ socket for RL78/G13 44-pin QFP devices. It ensures correct pin alignment, signal continuity, and mechanical stability - enabling accurate real-time debugging without modifying the target PCB layout. The QB-44FP-EA-01T does not process signals; it routes them passively per Renesas' official RL78/G13 emulation specification.

Can QB-44FP-EA-01T be used with RL78/G12 microcontrollers or other package types?

No. QB-44FP-EA-01T is explicitly designated for RL78/G13 44-pin QFP (FP) devices only, as confirmed in Table 1-3 of the QB-RL78G13 User's Manual. It is incompatible with RL78/G12, 32-pin, 48-pin, or TQFP variants - each requires its own exchange adapter (e.g., QB-32NA-EA-02S or QB-48FB-EA-01T). Using QB-44FP-EA-01T with non-matching targets risks misalignment, signal corruption, or physical damage.

Which additional components are required to use QB-44FP-EA-01T in a functional setup?

To deploy QB-44FP-EA-01T, you must also use QB-44FP-YQ-01T (to connect the adapter to the QB-RL78G13 emulator), QB-44FP-NQ-01T (soldered onto the target board), and QB-80-EP-01T (emulation probe). Optional components include QB-44FP-YS-01T for height adjustment and QB-44FP-HQ-01T mount adapter if socketing the target device. All are listed in the QB-RL78G13-T44FP package contents.

Does QB-44FP-EA-01T include any active circuitry, voltage translation, or configuration settings?

No. QB-44FP-EA-01T is a passive, zero-power adapter with no ICs, resistors, capacitors, or configurable elements. It provides direct, unmultiplexed 1:1 signal routing between YQ and NQ interfaces. Voltage levels, timing, and logic states are preserved exactly as delivered by the QB-RL78G13 emulator or target system - no level shifting, buffering, or clock conditioning is performed by QB-44FP-EA-01T itself.

Is QB-44FP-EA-01T compatible with third-party emulators or debuggers outside the Renesas IECUBE ecosystem?

No. QB-44FP-EA-01T is mechanically and electrically designed exclusively for use with the QB-RL78G13 in-circuit emulator and its associated accessories (YQ/NQ connectors, space adapters, probes). Its pinout, footprint, and mating force profile conform to Renesas' proprietary IECUBE interface standard. It is not interoperable with Segger J-Link, ST-LINK, or generic ARM SWD debuggers - even if they support RL78/G13 software protocols.
