Renesas QB-64FA-HQ-01T

Overview

QB-64FA-HQ-01T from Renesas Electronics is a mount adapter designed for the RL78/L12 64-pin flat package (64FA) microcontroller, enabling secure socket-based connection between the QB-RL78L12 in-circuit emulator and target systems. It supports 1.6–5.5 V operation, accommodates mechanical height adjustment via rear/front space adapters, and is rated for 0–40°C operating temperature. Used during firmware development and real-time debugging of RL78/L12-based embedded control applications.

For engineers reviewing the QB-64FA-HQ-01T datasheet, QB-64FA-HQ-01T pin compatibility, QB-64FA-HQ-01T mechanical fit, or QB-64FA-HQ-01T mounting interface alternatives, this page provides verified mechanical specifications, system integration context, physical dimensions, thermal handling guidance, and OEM supply support details specific to the QB-64FA-HQ-01T mount adapter.

Technical Context

The QB-64FA-HQ-01T is a passive mechanical interface component used exclusively with the QB-RL78L12 emulator and RL78/L12 64FA target devices. It mates with the QB-64FA-NQ-01T target connector and QB-64FA-YQ-01T YQ connector in T-type socket configurations.

It enables reliable signal integrity during high-speed emulation by maintaining precise pin alignment and Z-height control-critical for stable JTAG/SWCLK/SWDIO communication at up to 20 MHz system clock rates. Its design complies with Renesas' mechanical interface specification for 64-pin flat package devices.

FAQ

What is the primary function of the QB-64FA-HQ-01T?

The QB-64FA-HQ-01T is a mount adapter that mechanically secures the RL78/L12 64FA microcontroller into the QB-RL78L12 in-circuit emulator system. It ensures precise alignment and stable electrical contact when used with the QB-64FA-NQ-01T target connector and QB-64FA-YQ-01T YQ connector in T-type socket configurations. The QB-64FA-HQ-01T does not contain active circuitry and serves only as a passive mechanical interface.

Is QB-64FA-HQ-01T compatible with other RL78 emulator models like QB-RL78G13 or QB-RL78F14?

No. QB-64FA-HQ-01T is exclusively designed for use with the QB-RL78L12 in-circuit emulator and RL78/L12 64FA target devices. It is not mechanically or electrically compatible with other Renesas emulator platforms such as QB-RL78G13 or QB-RL78F14, which require their own dedicated adapter sets per package type and socket architecture.

Does QB-64FA-HQ-01T include electrical signal conditioning or level translation?

No. QB-64FA-HQ-01T is a purely passive mechanical adapter with no integrated circuitry, resistors, capacitors, or voltage translation functionality. Signal integrity relies entirely on the mating connectors (QB-64FA-NQ-01T, QB-64FA-YQ-01T) and the QB-RL78L12 emulator's internal interface logic. All voltage-level matching and timing compliance must be handled by the QB-RL78L12 and target system design.

Can QB-64FA-HQ-01T be used without the QB-64FA-YS-01T space adapter?

Yes - the QB-64FA-HQ-01T can be used without the QB-64FA-YS-01T space adapter, but only if the target PCB's component height and stack-up allow direct mating with the QB-64FA-NQ-01T and QB-64FA-YQ-01T. The QB-64FA-YS-01T is optional and provides vertical height adjustment (0–30 mm rear, 5–20 mm front) to accommodate varying PCB layouts. Use of QB-64FA-HQ-01T alone assumes zero-height offset requirements.

What are the key mechanical interfaces required to use QB-64FA-HQ-01T in a working setup?

To deploy QB-64FA-HQ-01T, you must use it in conjunction with three mandatory components: the QB-64FA-NQ-01T target connector (soldered to the target PCB), the QB-64FA-YQ-01T YQ connector (mating with the exchange adapter), and the QB-64FA-EA-01T exchange adapter (plugged into the QB-RL78L12). All four parts - QB-64FA-HQ-01T, QB-64FA-NQ-01T, QB-64FA-YQ-01T, and QB-64FA-EA-01T - form the complete T-type mechanical interface chain for the RL78/L12 64FA device.
