Renesas QB-64LA-NQ-01T

Overview

QB-64LA-NQ-01T from Renesas Electronics is a socket adapter designed for RL78 family microcontrollers in 64-pin FLGA (5×5 mm) packages, enabling connection between IECUBE emulation hardware and target boards via NQ-series interface cabling. It supports debug and programming of RL78/G1A, RL78/G1C, RL78/G1E, RL78/L12, and RL78/L1C MCUs with 64-pin FLGA footprint.

For engineers reviewing the QB-64LA-NQ-01T datasheet, QB-64LA-NQ-01T pinout, QB-64LA-NQ-01T application, or QB-64LA-NQ-01T equivalent, this adapter enables reliable JTAG/SWJ-based on-chip debugging and flash programming during embedded firmware development and validation phases.

Technical Context

The QB-64LA-NQ-01T is part of Renesas' IECUBE ecosystem and functions as a passive mechanical and electrical interface - it maps the 64-pin FLGA pad layout of RL78 MCUs to the standardized NQ-series connector used by IECUBE emulation probes. No active circuitry or signal conditioning is integrated.

It is paired exclusively with NQPACK064SD-ND (NQ-series 64-pin FLGA socket pack, manufactured by Tokyo Eletech Corporation) and requires use with an IECUBE main unit (e.g., QB-64GB-ZZZ or QB-64GK-ZZZ) and compatible target board header.

FAQ

What is the QB-64LA-NQ-01T used for?

The QB-64LA-NQ-01T is a dedicated socket adapter that bridges Renesas RL78 microcontrollers in 64-pin FLGA (5×5 mm) packages to the IECUBE NQ-series emulation probe. It enables JTAG/SWJ-based debugging and flash programming without soldering, supporting rapid firmware iteration and validation for QB-64LA-NQ-01T-compatible RL78 devices including RL78/G1A and RL78/L12 families.

Which RL78 MCUs are supported by the QB-64LA-NQ-01T?

The QB-64LA-NQ-01T supports RL78 microcontrollers packaged in 64-pin FLGA (5×5 mm), including RL78/G1A, RL78/G1C, RL78/G1E, RL78/L12, and RL78/L1C series. Compatibility is confirmed in Renesas' official IECUBE optional product list and aligns with the QB-64FC-NQ-01T reference designation shown alongside QB-64LA-NQ-01T in documentation.

Does the QB-64LA-NQ-01T include a socket?

No - the QB-64LA-NQ-01T is an adapter only and does not include a socket. It must be used with the separately purchased NQPACK064SD-ND socket pack (manufactured by Tokyo Eletech Corporation), which contains the physical FLGA socket and NQ-series connector assembly required for mounting and interfacing.

Is the QB-64LA-NQ-01T compatible with other IECUBE interface types like YQ or HQ?

No - the QB-64LA-NQ-01T is specifically designed for the NQ-series interface. It is mechanically and electrically incompatible with YQ, HQ, or YS variants. Each variant (e.g., QB-64LA-YQ-01T, QB-64LA-HQ-01T) uses distinct connector footprints and signal routing; mixing interfaces will result in physical misalignment and connection failure.

Can the QB-64LA-NQ-01T be used with non-RL78 targets?

No - the QB-64LA-NQ-01T is purpose-built for Renesas RL78 MCUs in 64-pin FLGA packages. Its pin mapping, signal assignments, and mechanical dimensions are optimized exclusively for RL78 debug protocols (e.g., SWJ-DP) and are not validated for other MCU families or package types.
