Renesas QB-52FA-EA-01T

Overview

QB-52FA-EA-01T from Renesas Electronics is an exchange adapter designed for the QB-RL78G13 in-circuit emulator, enabling physical and electrical interface conversion between the emulator's YQ connector and RL78/G13 target devices in 52-pin QFP packages. It supports T-type socket configuration, operates within 0–40°C ambient, and maintains signal integrity for real-time debugging of high-speed system clocks up to 20 MHz.

For engineers reviewing the QB-52FA-EA-01T datasheet, QB-52FA-EA-01T pinout, QB-52FA-EA-01T application, or QB-52FA-EA-01T equivalent, this adapter enables reliable connection to RL78/G13-based target systems using QB-52FA-NQ-01T target connectors and QB-52FA-YQ-01T YQ connectors - critical for debug setup validation, trace data capture, and non-stop execution analysis.

Technical Context

The QB-52FA-EA-01T is a passive mechanical and electrical interface adapter with no active circuitry, power requirements, or configurable logic. It maps all 52 signal pins between the QB-RL78G13 emulator's YQ interface and the target device's footprint, preserving timing-critical signals including X1/X2 clock inputs, RESET, VDD, VSS, and debug I/O lines such as BKFRQ, TRD0–TRD3, and MD.

It is used exclusively with the T-type socket variant of the QB-RL78G13 system and requires pairing with QB-52FA-YQ-01T (YQ connector) and QB-52FA-NQ-01T (target connector). No firmware, calibration, or host software configuration is needed - functionality is determined solely by physical pin alignment and impedance-matched routing per Renesas' IECUBE mechanical specification.

FAQ

What is the primary function of the QB-52FA-EA-01T in the QB-RL78G13 debug system?

The QB-52FA-EA-01T is a passive exchange adapter that bridges the QB-RL78G13 emulator's YQ interface to RL78/G13 microcontrollers in 52-pin QFP packages. It ensures correct pin mapping for clock, reset, debug, and power signals - enabling real-time emulation without modifying the target board layout. QB-52FA-EA-01T does not contain active components and relies entirely on mechanical alignment and signal routing per Renesas' IECUBE specification.

Is QB-52FA-EA-01T compatible with S-type socket configurations?

No, QB-52FA-EA-01T is explicitly designated for T-type socket use only, as confirmed by its part number suffix "-01T" and Renesas' Table 1-3 and Section 1.4 remarks. Attempting to use QB-52FA-EA-01T with an S-type system will result in mechanical misalignment and electrical disconnect. For S-type 52-pin variants, no equivalent exchange adapter is documented in the QB-RL78G13 manual.

Which companion parts are required to use QB-52FA-EA-01T successfully?

QB-52FA-EA-01T requires two mandatory companions: QB-52FA-YQ-01T (YQ connector) to interface with the QB-RL78G13 emulator, and QB-52FA-NQ-01T (target connector) soldered onto the RL78/G13 target board. Optional but recommended are QB-52FA-YS-01T (space adapter) and QB-52FA-HQ-01T (mount adapter) for mechanical stability during debugging sessions.

Does QB-52FA-EA-01T support high-speed system clock emulation up to 20 MHz?

Yes, QB-52FA-EA-01T preserves signal integrity for high-speed system clock signals (X1/X2) operating up to 20 MHz, as defined in QB-RL78G13 hardware specifications for RL78/G13 targets. Its passive design and controlled trace routing ensure minimal skew and reflection - critical for accurate real-time trace and breakpoint behavior during emulation of time-sensitive firmware routines using QB-52FA-EA-01T.

Can QB-52FA-EA-01T be used with RL78/G12 target devices?

No, QB-52FA-EA-01T is specified exclusively for RL78/G13 52-pin QFP devices per Renesas' Table 1-3 and QB-RL78G13-T52FA package listing. RL78/G12 devices use different pinouts, debug signal assignments, and voltage tolerances - making QB-52FA-EA-01T incompatible without verification from Renesas. Use of QB-52FA-EA-01T with G12 devices may cause connection failure or debug instability.
