Renesas QB-48GA-NQ-01T

Overview

QB-48GA-NQ-01T from Renesas Electronics is a target connector designed for in-circuit emulation of 78K0R/KD3-L and 78K0R/IC3 microcontrollers in 48-pin QFP packages. It provides reliable mechanical and electrical interface between the QB-78K0RIX3 emulator and target systems, supporting 1.8–5.5 V operation, 2–20 MHz system clock, and real-time debugging functions including trace, breakpoints, and register/memory manipulation.

For engineers reviewing the QB-48GA-NQ-01T datasheet, QB-48GA-NQ-01T pinout, QB-48GA-NQ-01T application, or QB-48GA-NQ-01T equivalent, this component is essential for establishing a stable debug interface during firmware development for Renesas 78K0R-based industrial control, motor drive, and appliance applications requiring precise timing and memory visibility.

Technical Context

The QB-48GA-NQ-01T is a passive, solder-mount target connector used exclusively with the QB-78K0RIX3 in-circuit emulator. It mates with the QB-48GA-YQ-01T YQ connector and interfaces directly to 48-pin QFP-packaged 78K0R/KD3-L and 78K0R/IC3 devices, maintaining signal integrity for high-speed debug communication up to 20 MHz.

It supports full voltage range operation (1.8–5.5 V) and is qualified for use across the standard quality grade - suitable for industrial robots, office equipment, and home appliances - with operating temperature from 0°C to +40°C and storage from −15°C to +60°C.

FAQ

What is the primary function of the QB-48GA-NQ-01T?

The QB-48GA-NQ-01T is a target connector that provides a physical and electrical interface between the QB-78K0RIX3 in-circuit emulator and 48-pin QFP-packaged 78K0R/KD3-L or 78K0R/IC3 microcontrollers. It ensures signal fidelity and mechanical alignment for real-time debugging, allowing full access to memory, registers, and trace functionality during firmware development. The QB-48GA-NQ-01T is not an active IC but a precision passive interconnect critical to the emulator's operational integrity.

Which microcontroller families does QB-48GA-NQ-01T support?

QB-48GA-NQ-01T supports two specific device groups: the 78K0R/KD3-L (e.g., μPD78F1008) and 78K0R/IC3 (e.g., μPD78F1009) microcontrollers, both in 48-pin QFP packages. It is explicitly listed in Table 1-3 of the QB-78K0RIX3 User's Manual as the designated target connector for these variants. It does not support other pin counts, packages, or unrelated MCU families such as RL78 or RX.

Is QB-48GA-NQ-01T compatible with other Renesas emulators?

No - QB-48GA-NQ-01T is designed exclusively for use with the QB-78K0RIX3 in-circuit emulator. It mates mechanically and electrically only with the QB-48GA-YQ-01T YQ connector and QB-78K0RIX3 main unit. It is not compatible with older QB-78K0RKX3L units (though functionally identical per note), nor with RA or RX-series emulators like E2 or E2 Lite, which use different connector architectures and pin mappings.

Does QB-48GA-NQ-01T require external power or configuration?

No - QB-48GA-NQ-01T is a passive, unpowered solder-mount connector with no active circuitry, configuration pins, or onboard logic. It requires no firmware, jumpers, or voltage selection. Its operation depends entirely on correct mechanical mounting to the target PCB and proper mating with the QB-48GA-YQ-01T and QB-78K0RIX3. All power and signal conditioning are handled by the emulator unit and target MCU.

What environmental conditions apply to QB-48GA-NQ-01T?

QB-48GA-NQ-01T is rated for operation at 0°C to +40°C with no condensation, and storage at −15°C to +60°C, consistent with its Standard quality grade classification. It is intended for use in non-life-critical applications including industrial robots, office equipment, and home appliances. It is not qualified for automotive, medical life-support, or aerospace environments without explicit Renesas written consent.
