Renesas QB-64BG-EA-02T

Overview

QB-64BG-EA-02T from Renesas Electronics is an exchange adapter designed for the QB-RL78G1A in-circuit emulator to interface with RL78/G1A microcontrollers in 64-pin LQFP (64BG) packages. It enables pin-conversion between the emulator's standard probe interface and the target device's footprint, supports 1.6–3.6 V operation, and is used with the QB-64BG-NQ-01T target connector in T-type configurations. It is required for debugging R5F10EL-series devices.

For engineers reviewing the QB-64BG-EA-02T datasheet, QB-64BG-EA-02T pinout, QB-64BG-EA-02T application, or QB-64BG-EA-02T equivalent, this adapter is essential for establishing reliable physical and signal-level connectivity between the QB-RL78G1A emulator and 64-pin LQFP RL78/G1A targets - particularly when using NQ-series target connectors and T-type mounting.

Technical Context

The QB-64BG-EA-02T is a passive mechanical and electrical interface component that maps QB-RL78G1A emulation probe signals to the pinout of 64-pin LQFP-packaged RL78/G1A microcontrollers (R5F10EL). It does not contain active circuitry, ICs, or power regulation.

It is used exclusively in T-type system configurations with the QB-64BG-NQ-01T target connector and requires no firmware, clock configuration, or voltage translation. Its design ensures signal integrity for debug interfaces including SWD, reset, trace, and power monitoring lines within the RL78/G1A's specified 1.6–3.6 V operating range.

Manufacturer

Renesas Electronics Corporation is a global semiconductor manufacturer specializing in microcontrollers, analog, and power solutions for automotive, industrial, and IoT applications.

QB-64BG-EA-02T belongs to the IECUBE in-circuit emulator accessory product line, engineered specifically to extend QB-RL78G1A compatibility to RL78/G1A devices in 64-pin LQFP packages without requiring custom probe design or PCB rework.

FAQ

Is QB-64BG-EA-02T compatible with S-type configurations or only T-type?

No, QB-64BG-EA-02T is designated exclusively for T-type configurations as confirmed in Table 1-3 of the QB-RL78G1A User's Manual. It is paired with QB-64BG-NQ-01T and does not support S-type sockets like QB-48NA-EA-02S or QB-32NA-EA-03S. Using QB-64BG-EA-02T in an S-type setup will result in mechanical and electrical incompatibility.

Does QB-64BG-EA-02T include active circuitry, voltage translation, or signal conditioning?

No, QB-64BG-EA-02T is a passive exchange adapter with no integrated ICs, regulators, level shifters, or active components. It provides direct pin-to-pin mapping between the QB-RL78G1A probe interface and the 64-pin LQFP footprint of the R5F10EL device. Signal integrity relies entirely on the host emulator and target board design.

What target connector must be used with QB-64BG-EA-02T?

QB-64BG-EA-02T must be used with QB-64BG-NQ-01T, as explicitly listed in Table 1-3 of the QB-RL78G1A User's Manual. No YQ connector, space adapter, or mount adapter is required or supported with this combination - the NQ connector mounts directly to the target system and mates mechanically with QB-64BG-EA-02T.

Can QB-64BG-EA-02T be used with non-RL78/G1A microcontrollers?

No, QB-64BG-EA-02T is functionally and mechanically qualified only for RL78/G1A devices in the 64-pin LQFP (64BG) package, specifically the R5F10EL series. Its pin mapping, signal routing, and mechanical cutouts are not validated for other families (e.g., RL78/G13, RL78/G14, or unrelated MCUs), and use with them may cause misalignment or signal shorts.

Is QB-64BG-EA-02T supplied separately or only bundled with QB-RL78G1A kits?

QB-64BG-EA-02T is supplied as part of the QB-RL78G1A-T64BG kit variant, which includes the QB-RL78G1A emulator unit, QB-80-EP-01T emulation probe, QB-64BG-EA-02T exchange adapter, and QB-64BG-NQ-01T target connector. It is also orderable individually under its exact part number for replacement or incremental deployment in existing QB-RL78G1A installations.
