Renesas QB-44GB-HQ-01T

Overview

QB-44GB-HQ-01T from Renesas Electronics is a mount adapter designed for 44-pin GB package 78K0R/Kx3-L and 78K0R/Ix3 microcontrollers, enabling secure socket-based target device installation during in-circuit emulation with the QB-78K0RIX3 emulator. It supports 1.8–5.5 V operation, accommodates high-speed system clocks up to 20 MHz, and is rated for 0–40°C operating temperature.

For engineers reviewing the QB-44GB-HQ-01T datasheet, QB-44GB-HQ-01T pinout, QB-44GB-HQ-01T application, or QB-44GB-HQ-01T equivalent, this component is critical for reliable mechanical interfacing between the QB-78K0RIX3 emulator and 44-pin GB-package 78K0R microcontrollers - especially when using exchange adapters (QB-44GB-EA-04T), space adapters (QB-44GB-YS-01T), and YQ connectors (QB-44GB-YQ-01T) in debug hardware setups.

Technical Context

The QB-44GB-HQ-01T is a passive mechanical interface component used exclusively with the QB-78K0RIX3 in-circuit emulator system. It mates directly with the target connector QB-44GB-NQ-01T and accepts the 44-pin GB-package microcontroller (e.g., μPD78F1007/8/9) in a socketed configuration.

No electrical functionality, signal conditioning, or power delivery is provided. Its design ensures precise alignment, thermal stability within 0–40°C, and mechanical compatibility with the QB-78K0RIX3's TC (Target Connector) mounting structure and YQ interconnect stack.

FAQ

What is the primary function of the QB-44GB-HQ-01T in the QB-78K0RIX3 emulator system?

The QB-44GB-HQ-01T is a mount adapter that mechanically secures 44-pin GB-package 78K0R microcontrollers (e.g., μPD78F1007/8/9) into a socketed interface compatible with the QB-78K0RIX3 emulator. It does not perform electrical functions but ensures precise alignment and stable physical connection between the target device and the QB-78K0RIX3's TC assembly. The QB-44GB-HQ-01T must be used with QB-44GB-NQ-01T and QB-44GB-YQ-01T to complete the signal path.

Which target microcontrollers are supported by QB-44GB-HQ-01T?

QB-44GB-HQ-01T supports all 44-pin GB-package variants in the 78K0R family listed in the QB-78K0RIX3 User's Manual, including 78K0R/KC3-L, 78K0R/IC3, and related devices such as μPD78F1007, μPD78F1008, and μPD78F1009. It is not compatible with GA, GK, MC, or F1 package variants - those require distinct mount adapters like QB-48GA-HQ-01T or QB-64GK-HQ-01T.

Does QB-44GB-HQ-01T provide electrical signal conditioning or voltage translation?

No, QB-44GB-HQ-01T is a purely passive mechanical adapter with no active or passive electronic circuitry. It contains no level shifters, buffers, terminators, or power regulation. Signal integrity relies entirely on the mating components: QB-44GB-NQ-01T (target connector), QB-44GB-YQ-01T (YQ connector), and the QB-78K0RIX3 main unit. All electrical specifications - including 1.8–5.5 V operation and 20 MHz clock support - are enforced by the emulator and target device, not the QB-44GB-HQ-01T.

Can QB-44GB-HQ-01T be used without other adapters in the QB-78K0RIX3 system?

No. QB-44GB-HQ-01T requires coordinated use with at least three other dedicated components: QB-44GB-NQ-01T (soldered to the target board), QB-44GB-YQ-01T (interconnecting YQ-to-TC), and QB-44GB-EA-04T (exchange adapter). Omitting any of these breaks the physical and electrical signal chain. The QB-44GB-HQ-01T alone cannot establish connectivity between the QB-78K0RIX3 and the target microcontroller.

Is QB-44GB-HQ-01T RoHS compliant and qualified for industrial applications?

Yes. QB-44GB-HQ-01T carries Renesas Electronics' "Standard" quality grade and complies with the EU RoHS Directive, as confirmed in official Renesas documentation and environmental compliance statements. It is approved for use in industrial robots, test and measurement equipment, communications infrastructure, and office automation systems - all within its specified 0–40°C operating temperature range and mechanical durability limits.
