Renesas QB-38SP-YQ-01T

Overview

QB-38SP-YQ-01T from Renesas Electronics is a YQ-series connector designed to interface the QB-38SP-EA-01T exchange adapter with the QB-38SP-NQ-01T target connector in the QB-RL78I1A in-circuit emulator system for RL78/I1A microcontrollers. It provides 38-position, surface-mount, right-angle mounting with gold-plated contacts and supports 2.7–5.5 V target system operation. It enables secure mechanical and electrical connection between emulator hardware and 38-pin SP-package target devices during debug sessions.

For engineers reviewing the QB-38SP-YQ-01T datasheet, QB-38SP-YQ-01T pinout, QB-38SP-YQ-01T application, or QB-38SP-YQ-01T equivalent, this component is critical for establishing reliable signal integrity and mechanical stability in RL78/I1A emulation setups - especially when integrating space adapters (QB-38SP-YS-01T), mount adapters (QB-38SP-HQ-01T), and high-characteristic FPC emulation probes (QB-80-EP-01T).

Technical Context

The QB-38SP-YQ-01T serves as a standardized interposer in Renesas' IECUBE emulator ecosystem, specifically for 38-pin SP-package RL78/I1A devices. It mates with the QB-38SP-NQ-01T target connector soldered onto the user's board and accepts the QB-38SP-EA-01T exchange adapter via its keyed, polarized interface.

Its design ensures precise alignment using guide pins (YQGUIDE), supports torque-limited fastening (0.054 Nm max), and maintains signal fidelity for high-speed debugging signals including clock (X1/X2), reset, trace, and JTAG/SWD lines - all within the QB-RL78I1A's 0–40°C operating range and 2.7–5.5 V supply envelope.

FAQ

Is QB-38SP-YQ-01T compatible with any target device other than RL78/I1A 38-pin SP-package devices?

No. QB-38SP-YQ-01T is explicitly designated for use only with the RL78/I1A 38-pin SP-package in the QB-RL78I1A emulator system. Table 1-3 of the QB-RL78I1A User's Manual confirms its pairing exclusively with QB-38SP-EA-01T, QB-38SP-NQ-01T, and QB-38SP-YS-01T - no cross-package or cross-family compatibility is supported or documented for QB-38SP-YQ-01T.

What mechanical fastening hardware is included with QB-38SP-YQ-01T?

QB-38SP-YQ-01T ships with four M2 × 10 mm screws and a dedicated YQGUIDE alignment fixture. The tightening torque must not exceed 0.054 Nm per screw to prevent damage to contact integrity or board stress - as specified in Section 2.3.2 of the QB-RL78I1A User's Manual.

Does QB-38SP-YQ-01T support high-speed clock signals up to 64 MHz used by the QB-RL78I1A emulator?

Yes. QB-38SP-YQ-01T is an integral part of the QB-RL78I1A signal path supporting the emulator's full clock capability - including PLL-derived 64 MHz operation for timers and peripherals. Its gold-plated contacts and controlled impedance layout maintain signal integrity for X1/X2 clock inputs, subsystem clock (32.768 kHz), and real-time trace signals as defined in Table 1-1 and Section 2.2 of the QB-RL78I1A manual.

Can QB-38SP-YQ-01T be used without the QB-38SP-YS-01T space adapter?

Yes - QB-38SP-YQ-01T can be mounted directly to QB-38SP-NQ-01T without the QB-38SP-YS-01T space adapter. However, the space adapter is required when height adjustment (0–30 mm) is needed to accommodate mechanical clearance between the emulator and target board - as noted in Figure 1-1 and Section 1.4 of the QB-RL78I1A manual.

Is QB-38SP-YQ-01T RoHS compliant and lead-free?

Yes. As a Renesas IECUBE accessory shipped with QB-RL78I1A-T38SP kits since 2012, QB-38SP-YQ-01T conforms to RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 3 marking requirements. Its termination finish and packaging meet Renesas' standard environmental compliance for development tools sold in EU, Japan, and North America markets.
