Renesas QB-32FP-YQ-01T

Overview

QB-32FP-YQ-01T from Renesas Electronics is a YQ-type connector designed for T-type socket configurations in the QB-RL78L12 in-circuit emulator system. It serves as the interface between the exchange adapter (QB-32FP-EA-02T) and the target connector (QB-32FP-NQ-01T), enabling physical and electrical connection to RL78/L12 32-pin QFP target devices. It supports 1.6–5.5 V operation, operates within 0–40°C ambient, and is rated for up to 250 mA target system current draw.

For engineers reviewing the QB-32FP-YQ-01T datasheet, QB-32FP-YQ-01T pinout, QB-32FP-YQ-01T application, or QB-32FP-YQ-01T equivalent, this component is essential for establishing reliable debug probe-to-target connectivity in RL78/L12-based embedded development-particularly when using T-type socket adapters with space-adjustable mounting configurations.

Technical Context

The QB-32FP-YQ-01T is a mechanical and electrical interposer that routes all 32 signal paths between the QB-32FP-EA-02T exchange adapter and QB-32FP-NQ-01T target connector without signal conditioning, level shifting, or active circuitry. It maintains direct continuity for emulation signals including RESET, CLK, VDD, VSS, and all I/O pins required by the RL78/L12 32FP package.

It is used exclusively in T-type socket configurations where height adjustment via QB-32FP-YS-01T space adapter is required. Its design ensures mechanical alignment tolerance compensation and low-inductance signal integrity for real-time trace and breakpoint debugging functions supported by the QB-RL78L12 emulator system.

FAQ

Is QB-32FP-YQ-01T a standalone debugging tool or an accessory?

QB-32FP-YQ-01T is a passive mechanical and electrical accessory-not a standalone tool. It functions only as part of the QB-RL78L12 in-circuit emulator system, specifically bridging the QB-32FP-EA-02T exchange adapter to the QB-32FP-NQ-01T target connector. It contains no active circuitry, firmware, or processing capability. The QB-32FP-YQ-01T must be used with the QB-RL78L12 main unit and compatible RL78/L12 target hardware to enable debugging functionality.

What socket type does QB-32FP-YQ-01T support?

QB-32FP-YQ-01T is explicitly designated for T-type socket configurations, as confirmed by its part number suffix "-01T" and its listing in Table 1-3 of the QB-RL78L12 User's Manual. It is incompatible with S-type sockets (e.g., those used with QB-48NA-EA-02S). Using QB-32FP-YQ-01T with non-T-type adapters may result in misalignment, contact failure, or damage to the connector or target board.

Can QB-32FP-YQ-01T be used with other RL78 families beyond L12?

No. QB-32FP-YQ-01T is qualified and dimensioned solely for the RL78/L12 32FP package, as stated in Table 1-3 of the QB-RL78L12 User's Manual. It is not validated for RL78/G13, RL78/G14, or any other RL78 subfamily-even if they share a 32-pin QFP footprint-due to differences in pin function mapping, voltage tolerances, and debug protocol requirements. Only RL78/L12 systems are supported per Renesas documentation.

Does QB-32FP-YQ-01T include ESD protection or signal conditioning?

No. QB-32FP-YQ-01T is a passive interconnect component with no integrated ESD protection diodes, termination resistors, or signal conditioning circuitry. All ESD handling and signal integrity rely on the upstream QB-RL78L12 emulator unit and downstream target board design. Users must observe Renesas' General Precautions-including avoiding hot-plug operations and ensuring GND potential matching-to prevent electrostatic damage during QB-32FP-YQ-01T installation or removal.

How does QB-32FP-YQ-01T integrate with space adapters?

QB-32FP-YQ-01T is designed to mate directly with the QB-32FP-YS-01T space adapter, which adjusts vertical height (0–30 mm) to accommodate varying target board stack-up tolerances. This pairing ensures mechanical stability and consistent pin engagement pressure across all 32 contacts. The QB-32FP-YQ-01T does not function independently of QB-32FP-YS-01T in T-type configurations where height compensation is required per Renesas' setup guidelines.
