Renesas QB-80FA-EA-02T

Overview

QB-80FA-EA-02T from Renesas Electronics is an emulation adapter socket set designed for RL78/L13 and RL78/L1C microcontrollers in 80-pin LQFP (12×12 mm) packages. It enables in-circuit debugging and flash programming via the IECUBE main unit (QB-xxxxxxx-ZZZ), supports target voltage range of 1.8–5.5 V, and provides direct connection to RL78 family MCUs using standard YQ-type probe interface.

For engineers reviewing the QB-80FA-EA-02T datasheet, QB-80FA-EA-02T pinout, QB-80FA-EA-02T application, or QB-80FA-EA-02T equivalent, this adapter is essential for establishing reliable debug connectivity between IECUBE hardware and 80-pin LQFP-based RL78/L13 and RL78/L1C devices during firmware development and validation.

Technical Context

This adapter implements a passive signal-routing interface between the IECUBE main unit's YQ connector and the target RL78 MCU's 80-pin LQFP footprint. It maps all required debug signals - including RESET, CLK, RXD/TXD, and SWDIO/SWCLK - while preserving power integrity and minimizing trace skew across the 12×12 mm LQFP pitch.

Designed exclusively for use with QB-RL78L1C-ZZZ and QB-RL78L13-ZZZ main units, the QB-80FA-EA-02T maintains full compatibility with Renesas' CS+ and e2 studio IDEs and supports both on-chip debug (OCD) and flash memory programming without requiring target board modifications.

FAQ

What is the primary function of the QB-80FA-EA-02T?

The QB-80FA-EA-02T is a socket adapter that enables physical and electrical interfacing between the IECUBE main unit (e.g., QB-RL78L1C-ZZZ) and 80-pin LQFP-packaged RL78/L13 and RL78/L1C microcontrollers. It routes debug and programming signals without modification to the target board, allowing full OCD functionality for firmware development using QB-80FA-EA-02T in conjunction with Renesas' official tools.

Which Renesas main units are compatible with QB-80FA-EA-02T?

QB-80FA-EA-02T is certified for use only with QB-RL78L1C-ZZZ and QB-RL78L13-ZZZ main units - both equipped with the YQ-type emulation probe interface. It is not compatible with NQ, HQ, or YS main units, nor with earlier IECUBE generations lacking YQ connector support. Renesas explicitly lists QB-80FA-EA-02T under "Socket Set" for these two main units in official documentation.

Does QB-80FA-EA-02T support voltage translation or level shifting?

No, QB-80FA-EA-02T is a passive signal-routing adapter with no active components. It assumes matching voltage domains between the IECUBE main unit and target MCU. The QB-80FA-EA-02T operates within the native 1.8–5.5 V supply range of RL78/L13 and RL78/L1C devices and requires external power regulation on the target board - QB-80FA-EA-02T itself does not provide level shifting.

Can QB-80FA-EA-02T be used with RL78/G13 or RL78/F14 MCUs?

No. QB-80FA-EA-02T is specifically designated for RL78/L13 and RL78/L1C families in 80-pin LQFP packages. RL78/G13 and RL78/F14 devices use different pinouts, debug register mappings, and voltage tolerances - Renesas assigns distinct socket part numbers (e.g., QB-80FB-EA-01T, QB-80FB-EA-04T) for those families. Using QB-80FA-EA-02T with non-L1x devices may result in incorrect signal routing or damage.

Is QB-80FA-EA-02T still in production or discontinued?

QB-80FA-EA-02T remains an active, orderable product per Renesas' current IECUBE optional product list (Page 4, RL78/L1C section). Unlike variants marked *1 (e.g., QB-100GC-EA-09T*1), QB-80FA-EA-02T carries no discontinuation notation and is supported alongside QB-80FB-EA-06T and QB-80FB-EA-07T for RL78/L1C development. Aetrix Electronics maintains live inventory and full technical documentation access for QB-80FA-EA-02T.
