Renesas QB-F14T38V850-01

Overview

QB-F14T38V850-01 from Renesas is a 38-pin to 14-pin interface adapter designed for connecting V850 target systems equipped with a Mictor connector to the E1 or E20 emulator's 14-pin user interface. It enables debug access while maintaining signal integrity for non-trace debugging, supports mechanical alignment via standardized footprint (25.0 mm × 20.0 mm), and is required when interfacing E20 emulators through the R0E000200CKA00 accessory chain.

For engineers reviewing the QB-F14T38V850-01 datasheet, QB-F14T38V850-01 pinout, QB-F14T38V850-01 application, or QB-F14T38V850-01 equivalent, this adapter resolves physical incompatibility between V850 target Mictor connectors and Renesas E1/E20 emulator interfaces-critical for safe JTAG-based firmware development, on-chip debugging setup, and trace-free validation workflows.

Technical Context

The QB-F14T38V850-01 bridges a fixed 38-pin Mictor interface on V850 target boards to the 14-pin standard used by Renesas E1 and E20 emulators. It does not support trace signals and is strictly passive-no active logic, voltage translation, or buffering is implemented.

Connection must follow strict sequencing: target system → QB-F14T38V850-01 → (for E20 only) R0E000200CKA00 → emulator. Direct Mictor-to-E20 connection is prohibited due to risk of smoke or fire.

FAQ

What is the primary function of the QB-F14T38V850-01?

The QB-F14T38V850-01 is a passive mechanical and electrical adapter that converts the 38-pin Mictor connector on V850 target systems to the 14-pin interface used by Renesas E1 and E20 emulators. It enables JTAG/SWD-based debugging without trace capability and requires strict adherence to connection sequence to avoid hardware damage. The QB-F14T38V850-01 contains no active components and relies entirely on correct pin mapping and signal routing.

Can QB-F14T38V850-01 be used directly with the E20 emulator?

No-QB-F14T38V850-01 cannot connect directly to the E20 emulator. When using E20, the QB-F14T38V850-01 must be paired with Renesas' standard accessory R0E000200CKA00 (38-pin/14-pin conversion adapter). The correct chain is: V850 target → QB-F14T38V850-01 → R0E000200CKA00 → E20. Direct Mictor-to-E20 connection risks smoke or fire, as explicitly warned in the QB-F14T38V850-01 User's Manual.

Does QB-F14T38V850-01 support trace signal routing?

No, QB-F14T38V850-01 does not support trace signal routing. The QB-F14T38V850-01 User's Manual explicitly states that V850-targeted E1/E20 emulators do not support trace signals, and this adapter is designed solely for JTAG and SWD debug communication. No trace pins are mapped or electrically supported in the QB-F14T38V850-01 pinout or internal layout.

What are the physical dimensions and mounting requirements for QB-F14T38V850-01?

The QB-F14T38V850-01 measures 25.0 mm × 20.0 mm in footprint, with no mounting holes or screw fixtures specified. It is intended for inline insertion between target board and emulator cable-no PCB soldering or mechanical fastening is required. Its compact size ensures compatibility with standard debug bench setups and avoids interference with adjacent connectors in dense test environments.

Is QB-F14T38V850-01 compatible with E1 emulator without additional accessories?

Yes-QB-F14T38V850-01 connects directly to the E1 emulator when used with a standard 14-pin interface cable. No intermediate adapter like R0E000200CKA00 is needed for E1. However, connection sequence remains critical: QB-F14T38V850-01 must be attached to the E1 first, then the USB cable and target system connected afterward, per safety instructions in the QB-F14T38V850-01 User's Manual.
