Renesas QB-30SP-EA-01T

Overview

QB-30SP-EA-01T from Renesas Electronics is an exchange adapter designed for the QB-RL78F12 in-circuit emulator, enabling physical and electrical interface conversion between the YQ connector and 30-pin SP (Small Outline Package) target devices. It supports RL78/F12 microcontrollers in 30SP packages, operates within 0–40°C ambient, and maintains signal integrity for real-time debugging at up to 32 MHz system clock. It is used during hardware-in-the-loop development of industrial control and automotive body electronics.

For engineers reviewing the QB-30SP-EA-01T datasheet, QB-30SP-EA-01T pinout, QB-30SP-EA-01T application, or QB-30SP-EA-01T equivalent, this page delivers verified mechanical compatibility data, target-device-specific signal mapping, mounting constraints, thermal handling limits, and integration guidance with the QB-RL78F12 emulator platform.

Technical Context

The QB-30SP-EA-01T serves exclusively as a passive pin-conversion interface between the QB-30SP-YQ-01T YQ connector and the QB-30SP-NQ-01T target connector on RL78/F12-based 30-pin SP package systems. It contains no active circuitry, ICs, or power domains - only precision-machined contacts and rigid PCB substrate.

It enables full trace, breakpoint, memory access, and real-time RAM monitoring functions of the QB-RL78F12 by preserving 1:1 signal routing for VDD, VSS, RESET, CLK, SWDIO, SWCLK, and all I/O pins mapped to the 30SP footprint. No voltage translation, level shifting, or timing compensation is performed.

FAQ

What is the primary function of the QB-30SP-EA-01T in the QB-RL78F12 emulator system?

The QB-30SP-EA-01T is a passive exchange adapter that provides precise mechanical and electrical pin mapping between the QB-30SP-YQ-01T YQ connector (emulator side) and the QB-30SP-NQ-01T target connector (30-pin SP device side). It enables reliable, low-noise signal transmission for full-featured debugging - including real-time trace, breakpoints, and memory access - without introducing timing skew or voltage translation. The QB-30SP-EA-01T itself contains no active components and requires no power or configuration.

Is QB-30SP-EA-01T compatible with non-RL78/F12 target devices or other package types?

No. QB-30SP-EA-01T is strictly qualified for use with RL78/F12 microcontrollers in the 30-pin SP package. Its pinout, spacing, and signal routing are mechanically and electrically optimized only for that specific device family and footprint. It is not interchangeable with adapters for 20SP, 48FB, or 64FB packages - each requires its own dedicated exchange adapter (e.g., QB-20SP-EA-03T or QB-64FB-EA-01T). Using QB-30SP-EA-01T with mismatched targets risks physical damage and signal corruption.

Does QB-30SP-EA-01T require firmware, drivers, or software configuration?

No. QB-30SP-EA-01T is a purely passive hardware interface with no embedded logic, memory, or programmable elements. It does not require firmware updates, driver installation, or CubeSuite+ configuration. All debugging intelligence resides in the QB-RL78F12 main unit and host software. QB-30SP-EA-01T functions immediately upon correct mechanical assembly with QB-30SP-YQ-01T and QB-30SP-NQ-01T - no initialization or enumeration is involved.

What mounting hardware and procedures are required for QB-30SP-EA-01T installation?

QB-30SP-EA-01T mounts using the supplied YQGUIDE alignment fixture and mechanical fasteners - no soldering or adhesive is applied to the adapter itself. It is inserted between QB-30SP-YQ-01T and QB-30SP-NQ-01T after both connectors are securely attached to their respective subsystems. Proper torque and alignment per Renesas' Section 2.3.2 must be followed to avoid bent pins or contact resistance increase. The QB-30SP-EA-01T must never be handled while powered or subjected to lateral force during connection.

Can QB-30SP-EA-01T be used with third-party emulators or debug probes?

No. QB-30SP-EA-01T is designed exclusively for integration within the Renesas IECUBE™ ecosystem - specifically with the QB-RL78F12 in-circuit emulator and its companion YQ/NQ connectors. Its mechanical dimensions, pin numbering, and signal layer stackup are not standardized for generic JTAG/SWD debug tools. Attempting use with non-Renesas emulators may result in physical interference, incorrect pin mapping, or loss of trace functionality due to unvalidated signal routing.
