Renesas QB-64FA-EA-01T

Overview

QB-64FA-EA-01T from Renesas Electronics is an exchange adapter designed for the QB-RL78G14 in-circuit emulator, enabling physical and electrical interface conversion between the emulator's YQ connector and the 64-pin QFP-packaged RL78/G14 target device (64FA package). It supports 1.6–5.5 V operation, maintains signal integrity for real-time debugging, and is used with the QB-64FA-NQ-01T target connector and QB-64FA-YQ-01T YQ connector in T-type configurations.

For engineers reviewing the QB-64FA-EA-01T datasheet, QB-64FA-EA-01T pinout, QB-64FA-EA-01T application, or QB-64FA-EA-01T equivalent, this adapter enables reliable debug probe interfacing for RL78/G14-based embedded control systems - particularly where mechanical height adjustment (via QB-64FA-YS-01T space adapter) and precise pin-mapped emulation are required.

Technical Context

The QB-64FA-EA-01T is a passive mechanical and electrical interface component that maps the QB-RL78G14 emulator's YQ connector pinout to the 64-pin QFP footprint of the RL78/G14 64FA device. It does not contain active circuitry, ICs, or power regulation - its function is strictly signal routing and pitch/height adaptation.

It is part of a T-type system configuration requiring QB-64FA-YQ-01T (YQ connector), QB-64FA-NQ-01T (target connector soldered to PCB), and optionally QB-64FA-YS-01T (space adapter) for vertical alignment. No voltage translation, level shifting, or timing compensation is performed.

FAQ

Is QB-64FA-EA-01T a standalone debugging tool or does it require other components?

QB-64FA-EA-01T is not a standalone tool - it is a mandatory interface component within the QB-RL78G14 T-type emulator system. To function, it must be used with QB-64FA-YQ-01T (YQ connector), QB-64FA-NQ-01T (target connector), and the QB-RL78G14 main unit. Without these, QB-64FA-EA-01T has no electrical or functional capability.

Does QB-64FA-EA-01T support both S-type and T-type emulator configurations?

No - QB-64FA-EA-01T is explicitly designated as a T-type adapter, as indicated by the "T" suffix in its part number and confirmed in Table 1-3 of the QB-RL78G14 User's Manual. S-type equivalents (e.g., QB-48NA-EA-01S) use different mechanical interfaces and pin layouts; mixing types causes physical incompatibility and signal misalignment.

Can QB-64FA-EA-01T be used with non-RL78/G14 microcontrollers?

No - QB-64FA-EA-01T is mechanically and electrically tailored exclusively for the RL78/G14 64FA package. Its pin count, pitch, pad layout, and signal assignment match only that specific device variant. Using it with other MCUs - even other RL78 sub-families - risks incorrect signal routing, physical damage, or failed debug sessions.

What is the role of QB-64FA-EA-01T in the signal path between QB-RL78G14 and the target system?

QB-64FA-EA-01T serves as a passive, impedance-uncompensated signal bridge: it routes each pin from the QB-64FA-YQ-01T connector directly to corresponding pins on the QB-64FA-NQ-01T target connector without buffering, level shifting, or timing modification. Its design preserves the QB-RL78G14's real-time trace and breakpoint capabilities by minimizing added capacitance and skew.

Is QB-64FA-EA-01T RoHS compliant and suitable for industrial temperature operation?

Yes - as a Renesas-branded accessory for the QB-RL78G14 emulator system, QB-64FA-EA-01T conforms to RoHS Directive 2011/65/EU and is rated for the same operating temperature range as the main emulator: 0°C to +40°C (non-condensing), per Section 1.1 of the QB-RL78G14 User's Manual (Rev. 2.00).
