Renesas QB-48GA-HQ-01T

Overview

QB-48GA-HQ-01T from Renesas Electronics is a mount adapter designed for 48-pin QFP (48GA) target devices in the 78K0R/Kx3-L and 78K0R/Ix3 microcontroller families. It enables secure mechanical mounting of the target IC onto the QB-78K0RIX3 in-circuit emulator system, supports 1.8–5.5 V operation, maintains signal integrity during real-time debugging, and is used with the QB-48GA-YQ-01T YQ connector and QB-48GA-NQ-01T target connector in production-grade debug setups.

For engineers reviewing the QB-48GA-HQ-01T datasheet, QB-48GA-HQ-01T pinout, QB-48GA-HQ-01T application, or QB-48GA-HQ-01T equivalent, this component is critical for reliable physical interface between the QB-78K0RIX3 emulator and 48-pin 78K0R microcontrollers - especially when validating timing-critical firmware execution, memory access traces, or register-level behavior under real-world voltage and temperature conditions (0–40°C).

Technical Context

The QB-48GA-HQ-01T is a passive mechanical adapter with no active circuitry, designed exclusively for use with the QB-78K0RIX3 emulator platform. It mates precisely with the QB-48GA-YQ-01T YQ connector and accommodates 48-pin QFP-packaged 78K0R microcontrollers including 78K0R/KD3-L and 78K0R/IC3.

It provides stable ZIF-style mechanical retention without soldering, preserves native pin mapping between emulator probe and target device, and is rated for repeated insertion/removal cycles within the QB-78K0RIX3 system's specified operating temperature range (0–40°C) and voltage supply envelope (1.8–5.5 V).

FAQ

What is the primary function of the QB-48GA-HQ-01T in the QB-78K0RIX3 emulator system?

The QB-48GA-HQ-01T is a mount adapter that physically secures 48-pin QFP-packaged 78K0R microcontrollers (e.g., 78K0R/KD3-L, 78K0R/IC3) onto the QB-78K0RIX3 in-circuit emulator platform. It ensures precise alignment and stable contact between the emulator probe and target device, enabling reliable real-time debugging without soldering. The QB-48GA-HQ-01T itself contains no electronics and functions solely as a mechanical interface component within the full QB-78K0RIX3 ecosystem.

Which target microcontrollers are confirmed compatible with QB-48GA-HQ-01T?

Per Renesas' official User's Manual U19228EJ1V0UM, Table 1-3, QB-48GA-HQ-01T is explicitly listed for use with 78K0R/KD3-L and 78K0R/IC3 - both packaged in 48-pin QFP (48GA). It is not validated for other pin counts or packages. Compatibility is limited to these two devices within the 78K0R/Kx3-L and 78K0R/Ix3 families, and requires pairing with QB-48GA-YQ-01T and QB-48GA-NQ-01T to complete the signal path.

Does QB-48GA-HQ-01T include electrical functionality such as level shifting or signal conditioning?

No. QB-48GA-HQ-01T is a purely passive mechanical adapter with no integrated circuitry, resistors, capacitors, or active components. It provides no voltage translation, impedance matching, or signal conditioning. All electrical characteristics - including voltage tolerance (1.8–5.5 V), timing fidelity, and noise immunity - are maintained by the upstream QB-78K0RIX3 emulator and associated probes. QB-48GA-HQ-01T serves only to align and retain the target IC physically.

Can QB-48GA-HQ-01T be used independently of the QB-78K0RIX3 emulator?

No. QB-48GA-HQ-01T has no standalone functionality and is not designed for use outside the QB-78K0RIX3 in-circuit emulator system. It lacks power inputs, debug interfaces, or host connectivity. Its sole purpose is to interface specific 48-pin 78K0R devices with the QB-78K0RIX3 base unit via the required chain of adapters: QB-48GA-EA-04T (exchange adapter), QB-48GA-YQ-01T (YQ connector), and QB-48GA-NQ-01T (target connector).

Is QB-48GA-HQ-01T RoHS compliant and qualified for industrial applications?

Yes. As a Renesas Electronics product released in April 2008 and covered under Document No. U19228EJ1V0UM, QB-48GA-HQ-01T conforms to RoHS Directive requirements per Renesas' environmental compliance policy. It is classified as "Standard" quality grade, certified for use in industrial robots, test/measurement equipment, and industrial embedded systems - consistent with its role in production-grade MCU debug infrastructure.
