Renesas QB-176GM-YQ-01T

Overview

QB-176GM-YQ-01T from Renesas Electronics is an Emulator Connector (YQ-type) designed for the QB-V850E2FX4H-PD in-circuit emulator system, interfacing the IE850 main unit to target V850E2/FK4, V850E2/FL4, and V850E2/FK4-H microcontrollers in 176-pin QFP packages. It supports 3.3V/5.0V target interface voltage, operates up to 160MHz, and enables real-time program execution, hardware break, trace, and time measurement functions.

For engineers reviewing the QB-176GM-YQ-01T datasheet, QB-176GM-YQ-01T pinout, QB-176GM-YQ-01T application, or QB-176GM-YQ-01T equivalent, this component is critical for establishing reliable physical signal routing between the IE850 emulator main unit and target systems using P272F1 or P-FQFP208 package variants - especially when debugging high-speed V850E2-based automotive or industrial control firmware.

Technical Context

The QB-176GM-YQ-01T serves as a mechanically and electrically matched interface bridge between the IE850 main unit and target boards hosting V850E2/FK4-H or V850E2/FL4 microcontrollers in 176-pin QFP packages. It routes debug signals including CPU bus cycles, trace data, break triggers, and clock synchronization while maintaining signal integrity at up to 160MHz operation.

It is used exclusively with the QB-V850E2FX4H-PD POD and requires pairing with QB-176GM-NQ-01T (Target Connector) and QB-176GM-EA-61T or QB-176GM-EA-62T (Exchange Adapter) depending on target device variant. No onboard logic or active circuitry is present - its function is purely passive interconnection with defined impedance and timing alignment per Renesas' IE850 system architecture.

FAQ

What is the primary function of the QB-176GM-YQ-01T in the IE850 emulator system?

The QB-176GM-YQ-01T is a dedicated Emulator Connector that physically and electrically links the IE850 main unit to the QB-V850E2FX4H-PD POD for V850E2/FK4-H and V850E2/FL4 target devices. It carries debug signals-including CPU bus traces, break triggers, and clock synchronization-without signal conditioning or logic translation. Its design ensures timing-aligned, low-noise connectivity essential for accurate 160MHz real-time emulation of QB-176GM-YQ-01T-compatible targets.

Which target microcontroller packages does QB-176GM-YQ-01T support?

QB-176GM-YQ-01T supports V850E2 microcontrollers in 176-pin QFP packages: specifically P272F1 and P-FQFP208 footprints. It is listed in Renesas documentation for V850E2/FK4, V850E2/FL4, V850E2/FK4-H, and V850E2/FK4-G devices. It must be used with matching QB-176GM-NQ-01T (Target Connector) and either QB-176GM-EA-61T or QB-176GM-EA-62T (Exchange Adapter) depending on target variant - QB-176GM-YQ-01T itself does not adapt package types.

Can QB-176GM-YQ-01T be used standalone without the QB-V850E2FX4H-PD POD?

No. QB-176GM-YQ-01T is not functional as a standalone unit. It is a passive interface component requiring the QB-V850E2FX4H-PD POD, IE850 main unit, AC adapter, and appropriate target socket (QB-176GM-NQ-01T) to form a complete in-circuit emulation system. Renesas explicitly states "POD cannot be used alone" and lists QB-176GM-YQ-01T only as part of the integrated QB-V850E2FX4H-PD configuration - no independent electrical specifications or operational modes are defined for QB-176GM-YQ-01T outside this context.

Does QB-176GM-YQ-01T support both 3.3V and 5.0V target interface voltages?

Yes. QB-176GM-YQ-01T is designed to route target interface signals operating at either 3.3V or 5.0V, as confirmed by Renesas' Hardware Specification table listing REGxVDD, FVDD0, ExVDD, B0VDD, AxVDD, and AxVREFP pins with "3.3V or 5.0V" tolerance. This dual-voltage compatibility allows seamless integration with V850E2 target systems configured for either logic level - critical for legacy 5V industrial designs and modern 3.3V automotive implementations using QB-176GM-YQ-01T.

Is QB-176GM-YQ-01T RoHS compliant and suitable for automotive applications?

QB-176GM-YQ-01T falls under Renesas' "Standard" quality grade per their official notice, intended for office equipment, test/measurement gear, and industrial robots - not "High Quality" transportation or safety-critical systems. While RoHS compliance is expected (Renesas mandates adherence to EU directives), no explicit environmental certification is stated in the provided documentation. For automotive use, designers must verify full qualification status directly with Renesas sales, as QB-176GM-YQ-01T's role is limited to development tooling - not end-product deployment.
