Renesas QB-30SP-EA-02T

Overview

QB-30SP-EA-02T from Renesas Electronics is an exchange adapter designed for the QB-RL78I1A in-circuit emulator, enabling physical and electrical interface conversion between the YQ connector and the 30-pin SP (30SP) target device package. It supports RL78/I1A microcontroller emulation at system clock frequencies up to 32 MHz, provides pin-mapped signal routing for debug signals (including clock, reset, trace, and JTAG/SWD-compatible control lines), and is used in conjunction with QB-30SP-YQ-01T and QB-30SP-NQ-01T for secure mechanical mounting on 30SP-based target boards.

For engineers reviewing the QB-30SP-EA-02T datasheet, QB-30SP-EA-02T pinout, QB-30SP-EA-02T application, or QB-30SP-EA-02T equivalent, this adapter is critical for establishing reliable debug connectivity between the QB-RL78I1A emulator and RL78/I1A-based 30-pin surface-mount target systems - especially where board-level space constraints, height alignment, or signal integrity require precise mechanical and electrical translation.

Technical Context

The QB-30SP-EA-02T functions as a passive, zero-power signal translation interface between the QB-RL78I1A's YQ connector and the 30SP target package footprint. It maps all essential debug and clock signals-including TRST, TCK, TMS, TDI, TDO, RESET, VDD, GND, X1, X2, XT1, XT2, and trace bus lines-without buffering, level-shifting, or timing modification. Its design assumes direct compatibility with the QB-30SP-YQ-01T and QB-30SP-NQ-01T mechanical stack-up.

It operates within the same environmental envelope as the QB-RL78I1A system: 0°C to 40°C operating temperature, no condensation, and requires no external power or configuration. Signal integrity is maintained via controlled impedance routing and gold-plated contact surfaces compliant with IECUBE mechanical and electrical interface specifications.

FAQ

Is QB-30SP-EA-02T a standalone debugging tool?

No, QB-30SP-EA-02T is not a standalone tool. It is a passive mechanical and electrical interface adapter that must be used with the QB-RL78I1A in-circuit emulator, QB-30SP-YQ-01T, and QB-30SP-NQ-01T to establish debug connectivity to RL78/I1A 30SP target systems. QB-30SP-EA-02T itself contains no active circuitry, firmware, or power interface.

What is the pin count and pitch of QB-30SP-EA-02T?

QB-30SP-EA-02T is designed for the 30-pin SP package with 0.65 mm pitch, matching the pin layout and mechanical footprint of the RL78/I1A 30SP device. Its pinout is defined by Renesas' QB-30SP-EA-02T drawing and is fully compatible only with QB-30SP-YQ-01T (YQ side) and QB-30SP-NQ-01T (NQ side).

Does QB-30SP-EA-02T support voltage level translation?

No, QB-30SP-EA-02T does not perform voltage level translation. It provides direct, passive signal routing between the QB-RL78I1A and the target system. Voltage compatibility depends on the QB-RL78I1A's configured I/O voltage (2.7–5.5 V) and must match the target system's VDD level - QB-30SP-EA-02T imposes no additional level-shifting function.

Can QB-30SP-EA-02T be used with other Renesas emulators like QB-RX231 or QB-RL78G14?

No, QB-30SP-EA-02T is exclusively qualified and mechanically dimensioned for use with the QB-RL78I1A in-circuit emulator. It is not compatible with QB-RX231, QB-RL78G14, or other IECUBE variants due to differences in YQ connector design, signal routing, and mechanical stack-up requirements.

Is QB-30SP-EA-02T RoHS compliant and lead-free?

Yes, QB-30SP-EA-02T conforms to RoHS Directive 2011/65/EU and is manufactured using lead-free solder and halogen-free materials, consistent with Renesas Electronics' standard environmental compliance for IECUBE accessories as documented in R20UT0766EJ and related product declarations.
