Renesas QB-36LA-EA-02T

Overview

QB-36LA-EA-02T from Renesas Electronics is a T-type exchange adapter designed for use with the QB-RL78G1F in-circuit emulator to interface with RL78/G1F microcontrollers in 36-pin LGA (Land Grid Array) packages. It enables physical and signal-level connection between the emulator and target device, supports high-fidelity emulation probe coupling, and operates within 0°C to 40°C ambient conditions for development-stage debugging.

For engineers reviewing the QB-36LA-EA-02T datasheet, QB-36LA-EA-02T pinout, QB-36LA-EA-02T application, or QB-36LA-EA-02T equivalent, this adapter is essential when debugging RL78/G1F-based systems using the T-type connector architecture - particularly where precise mechanical alignment, low-inductance signal routing, and compatibility with QB-36LA-NQ-01T target connectors are required.

Technical Context

The QB-36LA-EA-02T serves exclusively as a passive mechanical and electrical interface between the QB-RL78G1F emulator base unit and the QB-36LA-NQ-01T target connector mounted on the RL78/G1F evaluation board. It provides no active circuitry, voltage translation, or signal conditioning - its function is strictly pin-mapped signal pass-through with impedance-controlled routing optimized for debug clock and trace signals up to 120 MHz.

It is dimensionally engineered to accommodate height-adjustable mounting via optional space adapters and integrates with YQ connectors (e.g., QB-36LA-YQ-01T) to ensure stable mating force and repeatable contact resistance under thermal cycling. No firmware, configuration, or host-side driver support is required.

FAQ

What is the primary function of the QB-36LA-EA-02T in an RL78/G1F debug setup?

The QB-36LA-EA-02T is a T-type exchange adapter that physically and electrically bridges the QB-RL78G1F in-circuit emulator to the QB-36LA-NQ-01T target connector on RL78/G1F evaluation boards. It ensures precise pin alignment, low-signal-loss routing, and mechanical stability - enabling full-featured debugging including real-time execution, memory manipulation, and 120 MHz trace capture. The QB-36LA-EA-02T itself contains no active components and requires no configuration.

Can the QB-36LA-EA-02T be used with S-type emulation probes or TCN1/TCN3 connectors?

No. The QB-36LA-EA-02T is explicitly designated as a T-type adapter and is incompatible with S-type configurations, check pin adapters (e.g., QB-144-CA-01), or direct TCN1/TCN3 probe connections. Its mechanical design, pin layout, and mating interface are engineered only for use with the QB-36LA-NQ-01T target connector and associated T-type accessories like QB-36LA-YQ-01T and QB-36LA-YS-01T. Attempting S-type integration will result in misalignment and unreliable signal integrity.

Does the QB-36LA-EA-02T require firmware updates or software configuration?

No. The QB-36LA-EA-02T is a passive mechanical adapter with no embedded logic, memory, or programmable elements. It does not require firmware, drivers, or host-side configuration. All debug functionality - including clock source selection, trace mode, and breakpoint handling - is managed by the QB-RL78G1F emulator unit and associated debugger software. The QB-36LA-EA-02T functions solely as a precision signal conduit.

Is the QB-36LA-EA-02T compatible with other RL78 families beyond the G1F series?

No. According to Renesas documentation, the QB-36LA-EA-02T is qualified exclusively for the RL78/G1F microcontroller in the 36-pin LGA package. It is not validated for RL78/G13, G14, or G1P devices - even if they share similar pin counts - due to differences in pinout assignment, voltage tolerances, and debug interface implementation. Using it with non-G1F targets may cause signal conflicts or physical damage.

What accessories must be used alongside the QB-36LA-EA-02T to complete a functional debug setup?

To complete a functional debug setup, the QB-36LA-EA-02T must be used with: (1) QB-RL78G1F in-circuit emulator base unit, (2) QB-36LA-NQ-01T target connector soldered to the RL78/G1F board, (3) QB-36LA-YQ-01T YQ connector for secure mating, and optionally (4) QB-36LA-YS-01T space adapter for height adjustment. The QB-36LA-EA-02T alone cannot establish a debug link - it is one mandatory element in a defined T-type adapter stack.
