Renesas QB-64BG-EA-01T

Overview

QB-64BG-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 the 64-pin BG (Ball Grid) package target device. It supports RL78/G13 microcontrollers, operates within 0–40°C ambient, and is rated for 1.6–5.5 V system voltage compatibility. Used with QB-64BG-NQ-01T target connector and QB-80-EP-01T emulation probe.

For engineers reviewing the QB-64BG-EA-01T datasheet, QB-64BG-EA-01T pinout, QB-64BG-EA-01T application, or QB-64BG-EA-01T equivalent, this adapter enables reliable debug connection to RL78/G13-based 64-pin BG-packaged MCUs without modifying target board layout - critical during firmware validation, timing analysis, and real-time RAM monitoring workflows.

Technical Context

The QB-64BG-EA-01T serves exclusively as a passive mechanical and signal-mapped bridge between the QB-RL78G13 emulator's YQ interface and the target device's 64-pin BG footprint. It does not contain active circuitry, power regulation, or clock generation - all timing and voltage references are passed through from the emulator or target system.

It is mechanically optimized for T-type socket configurations and requires pairing with QB-64BG-NQ-01T (target connector) and QB-64BG-YQ-01T (YQ connector) to complete the signal path. No configuration switches, jumpers, or firmware are associated with this adapter.

FAQ

What is the primary function of the QB-64BG-EA-01T?

The QB-64BG-EA-01T is a passive exchange adapter that maps the QB-RL78G13 emulator's YQ interface to the physical pin layout of 64-pin BG-package RL78/G13 microcontrollers. It enables secure, low-signal-integrity-loss connection for real-time debugging - including program execution control, memory/register manipulation, and trace data capture - without requiring custom cabling or PCB modification. QB-64BG-EA-01T itself contains no active components or configuration logic.

Which target devices and packages does QB-64BG-EA-01T support?

QB-64BG-EA-01T is explicitly validated for RL78/G13 microcontrollers in 64-pin BG (Ball Grid) package only, as documented in Renesas Table 1-3 of the QB-RL78G13 User's Manual Rev.2.00. It is not compatible with other pin counts, package types (e.g., LQFP, QFN), or device families such as RL78/G12 - even if pin-count matches - due to unique ball map and signal routing requirements.

Does QB-64BG-EA-01T require power or configuration?

No. QB-64BG-EA-01T is a passive interconnect adapter with no internal power circuitry, voltage regulation, or programmable elements. It draws no current and requires no firmware, jumpers, or DIP switches. All power, clock, and debug signals pass directly between QB-RL78G13 and the target system via its mating connectors - QB-64BG-YQ-01T and QB-64BG-NQ-01T - preserving signal integrity and timing accuracy.

What companion parts are mandatory for QB-64BG-EA-01T to function?

QB-64BG-EA-01T requires two mandatory companion parts: QB-64BG-YQ-01T (YQ connector) to interface with the QB-RL78G13 emulator, and QB-64BG-NQ-01T (target connector) soldered onto the target board. These three components form the complete signal chain. The QB-80-EP-01T emulation probe is also required for physical mounting but is not electrically in series with QB-64BG-EA-01T.

Can QB-64BG-EA-01T be used with other Renesas emulators like QB-RL78G12 or IECUBE models?

No. QB-64BG-EA-01T is designed and validated exclusively for use with the QB-RL78G13 in-circuit emulator. Its mechanical dimensions, pin mapping, and signal routing align only with QB-RL78G13's YQ interface and RL78/G13-specific debug architecture. It is incompatible with QB-RL78G12, older IECUBE units, or third-party debuggers - even if physically mated - due to differences in debug protocol timing, voltage thresholds, and pin functional assignment.
