Renesas QB-64FA-YQ-01T

Overview

QB-64FA-YQ-01T from Renesas Electronics is a YQ-series connector designed for in-circuit emulation of RL78/L13 microcontrollers in 64-pin fine-pitch QFP packages. It serves as the interface between exchange adapter QB-64FA-EA-02T and target connector QB-64FA-NQ-01T, supporting 1.6–5.5 V operation, 0–40°C ambient range, and mechanical alignment for high-fidelity signal integrity during debug sessions on industrial embedded systems.

For engineers reviewing the QB-64FA-YQ-01T datasheet, QB-64FA-YQ-01T pinout, QB-64FA-YQ-01T application, or QB-64FA-YQ-01T equivalent, this component is critical for establishing reliable physical-layer connectivity in RL78/L13-based emulator setups - especially where board-level height adjustment, ESD-safe mating cycles, and low-inductance signal routing are required.

Technical Context

The QB-64FA-YQ-01T is a passive, zero-insertion-force (ZIF) compatible interconnect module used exclusively within Renesas' QB-RL78L1C in-circuit emulator ecosystem. It mates with QB-64FA-EA-02T (exchange adapter) on one side and QB-64FA-NQ-01T (target connector) on the other, enabling mechanical decoupling of emulator probe signals from the target PCB while preserving pin-to-pin continuity for all 64 I/O, power, and debug lines.

No active circuitry, voltage translation, or signal conditioning is integrated. Its design strictly adheres to RL78/L13 64FA package footprint (0.5 mm pitch, 10 mm × 10 mm body), supports up to 500 mating cycles per IEC 60664-1, and complies with RoHS Directive 2011/65/EU for lead-free soldering compatibility.

FAQ

What is the primary function of QB-64FA-YQ-01T in the QB-RL78L1C emulator system?

QB-64FA-YQ-01T functions as a dedicated interposer connector that bridges the exchange adapter (QB-64FA-EA-02T) and target connector (QB-64FA-NQ-01T) in the QB-RL78L1C in-circuit emulator setup. It ensures precise mechanical alignment and electrical continuity for all 64 pins of the RL78/L13 64FA package during debugging, without signal conditioning or active circuitry. The QB-64FA-YQ-01T enables modular, serviceable emulation hardware configurations while maintaining signal integrity across debug sessions.

Is QB-64FA-YQ-01T compatible with other RL78 family devices beyond RL78/L13?

No - QB-64FA-YQ-01T is mechanically and electrically specified only for RL78/L13 devices in the 64-pin FA package. Its pin layout, pitch (0.5 mm), and footprint match QB-64FA-EA-02T and QB-64FA-NQ-01T, which are explicitly designated for RL78/L13 in Table 1-3 of the QB-RL78L1C User's Manual. It is not interchangeable with connectors for RL78/L1C (e.g., QB-80FB-YQ-01T) or other variants due to differing package dimensions and pinouts. The QB-64FA-YQ-01T must be used exclusively in RL78/L13 64FA-targeted emulator configurations.

Does QB-64FA-YQ-01T include any active components or circuitry?

No - QB-64FA-YQ-01T is a passive, zero-insertion-force (ZIF)-compatible interconnect module with no integrated semiconductors, resistors, capacitors, or ICs. It provides direct metallic continuity between mating contacts and contains no voltage regulation, level shifting, or signal conditioning. All functionality is purely mechanical and electrical interconnection; its performance depends entirely on proper soldering, mating force, and PCB layout adherence to Renesas' recommended land patterns. The QB-64FA-YQ-01T operates solely as a signal-passive bridge in the emulator chain.

What environmental compliance certifications apply to QB-64FA-YQ-01T?

QB-64FA-YQ-01T complies with the EU RoHS Directive 2011/65/EU, confirmed via Renesas' material declarations and manufacturing process controls. It features lead-free terminations and is qualified for standard reflow soldering profiles. No additional certifications (e.g., REACH, halogen-free, or automotive AEC-Q200) are assigned to QB-64FA-YQ-01T, as it is classified as an emulator accessory rather than a standalone component for end-equipment. The QB-64FA-YQ-01T meets baseline industrial environmental requirements per Renesas' "Standard" quality grade classification.

Can QB-64FA-YQ-01T be used without the QB-RL78L1C emulator base unit?

No - QB-64FA-YQ-01T has no standalone functionality and is not intended for use outside the QB-RL78L1C in-circuit emulator system. It lacks power delivery capability, debug protocol logic, or host interface circuitry. Its sole purpose is to complete the physical signal path between QB-64FA-EA-02T and QB-64FA-NQ-01T when paired with the QB-RL78L1C main unit, USB host connection, and compatible software tools. Using QB-64FA-YQ-01T independently would result in no operational behavior, as it contains no active elements or interface capability. The QB-64FA-YQ-01T is strictly an accessory part within the defined emulator architecture.
