Renesas QB-64FA-EA-02T

Overview

QB-64FA-EA-02T from Renesas Electronics is an exchange adapter designed for in-circuit emulation of the RL78/L13 microcontroller in 64-pin QFN (64FA) package. It enables physical pin conversion between the QB-RL78L1C emulator and target systems, supports 1.6–5.5 V operation, accommodates up to 20 MHz system clock, and is used with YQ connector QB-64FA-YQ-01T and NQ target connector QB-64FA-NQ-01T in RL78/L13 development environments.

For engineers reviewing the QB-64FA-EA-02T datasheet, QB-64FA-EA-02T pinout, QB-64FA-EA-02T application, or QB-64FA-EA-02T equivalent, this adapter is essential for establishing reliable debug connectivity between the QB-RL78L1C emulator and RL78/L13-based target hardware - particularly where mechanical alignment, signal integrity, and voltage-level compatibility across the emulation interface must be maintained.

Technical Context

The QB-64FA-EA-02T serves exclusively as a passive mechanical and electrical interface bridge - it contains no active circuitry, ICs, or logic. Its function is strictly to remap pin assignments between the QB-RL78L1C's standard probe interface and the 64-pin QFN footprint of the RL78/L13 device, preserving signal routing integrity for debug signals including RESET, CLK, SWDIO, SWCLK, and power/ground lines.

It is used in conjunction with QB-64FA-YQ-01T (YQ connector) and QB-64FA-NQ-01T (target connector), forming a calibrated three-part interconnect stack that maintains controlled impedance paths and minimizes skew for high-fidelity real-time trace and breakpoint debugging of RL78/L13 applications operating at up to 20 MHz.

FAQ

Is QB-64FA-EA-02T an active electronic component or a passive adapter?

QB-64FA-EA-02T is a passive mechanical adapter with no active circuitry, ICs, or power requirements. It performs only physical pin mapping between the QB-RL78L1C emulator and the RL78/L13 64FA target device - all signal integrity and timing depend entirely on the connected YQ and NQ components and the host emulator's internal drivers. QB-64FA-EA-02T itself does not buffer, level-shift, or condition any signals.

Which RL78 devices is QB-64FA-EA-02T specifically qualified for?

QB-64FA-EA-02T is explicitly qualified for the RL78/L13 microcontroller in the 64-pin QFN (64FA) package only. It is not compatible with RL78/L1C or other RL78 variants - those require different exchange adapters such as QB-80FB-EA-06T (for 80FB) or QB-64FB-EA-05T (for 64FB). The part number suffix "64FA" directly encodes the target package type.

What accessories must be used with QB-64FA-EA-02T to complete the emulation chain?

To establish a functional debug link, QB-64FA-EA-02T must be used with QB-64FA-YQ-01T (YQ connector) and QB-64FA-NQ-01T (target connector), as specified in Renesas' official system configuration documentation. These three components form a calibrated stack: QB-64FA-EA-02T converts pin layout, QB-64FA-YQ-01T interfaces to the emulator probe, and QB-64FA-NQ-01T mounts to the target PCB.

Does QB-64FA-EA-02T support high-speed trace or real-time RAM monitoring?

No - QB-64FA-EA-02T provides no trace or memory monitoring capability. Those functions are implemented entirely within the QB-RL78L1C emulator unit (e.g., its 128K-frame trace buffer and real-time RAM monitoring engine). QB-64FA-EA-02T's sole role is to maintain low-loss, low-skew signal routing for debug interface signals (SWDIO, SWCLK, RESET, etc.) so that the emulator's native features operate correctly on the RL78/L13 target.

Can QB-64FA-EA-02T be used with other Renesas emulators like E2 or E2 Lite?

No - QB-64FA-EA-02T is mechanically and electrically designed exclusively for the QB-RL78L1C in-circuit emulator platform. It is not compatible with E2 or E2 Lite debuggers, which use different probe interfaces, pinouts, and mechanical mounting schemes. Using QB-64FA-EA-02T with non-QB-RL78L1C hardware may result in misalignment, contact failure, or damage to connectors.
