Renesas QB-100FB-YQ-01T

Overview

QB-100FB-YQ-01T from Renesas Electronics is a T-type YQ connector used with the QB-RL78G14 in-circuit emulator to interface the exchange adapter (QB-100FB-EA-01T) to the target connector (QB-100FB-NQ-01T) on RL78/G14-based 100-pin FBGA target systems. It supports mechanical alignment, signal integrity preservation, and hot-plug-safe mating under powered conditions per IECUBE handling guidelines. It is rated for 0–40°C operation and designed for use with QB-RL78G14 debugging setups.

For engineers reviewing the QB-100FB-YQ-01T datasheet, QB-100FB-YQ-01T pinout, QB-100FB-YQ-01T application, or QB-100FB-YQ-01T equivalent, this page delivers verified mechanical interface specifications, system-level integration context, compatibility constraints with QB-100FB-EA-01T and QB-100FB-NQ-01T, and precise usage guidance aligned with Renesas' QB-RL78G14 User's Manual Rev.2.00.

Technical Context

The QB-100FB-YQ-01T is a passive, non-electronic mechanical interconnect component - not an IC, discrete, or frequency control device - and serves exclusively as a standardized mating interface between the QB-100FB-EA-01T exchange adapter and QB-100FB-NQ-01T target connector in the QB-RL78G14 emulation system. It has no active circuitry, voltage rating, or signal conditioning function.

Its design conforms to Renesas' T-type socket architecture for 100-pin FBGA devices, enabling height-adjustable mounting via optional space adapters (e.g., QB-100FB-YS-01T), and requires strict adherence to handling cautions: no plugging/unplugging while powered, no excessive bending or pulling of attached cables, and no GND potential difference between emulator and target system during connection.

FAQ

Is QB-100FB-YQ-01T an electronic component or integrated circuit?

No, QB-100FB-YQ-01T is a passive mechanical connector - not an IC, discrete semiconductor, or active timing device. It contains no silicon, transistors, or electrical functionality. Its sole purpose is physical and mechanical interfacing between the QB-100FB-EA-01T exchange adapter and QB-100FB-NQ-01T target connector in the QB-RL78G14 emulation system, as defined in Renesas' QB-RL78G14 User's Manual Rev.2.00.

What is the exact target device and package supported by QB-100FB-YQ-01T?

QB-100FB-YQ-01T is explicitly designated for the RL78/G14 microcontroller in 100-pin FBGA (Fine-Pitch Ball Grid Array) package. This is confirmed in Table 1-3 "Adapters and Connectors for Each Target Device" of the QB-RL78G14 User's Manual, where QB-100FB-YQ-01T is listed solely under the "100FB" row and "YQ Connector" column - no other device or package is associated with this part number.

Can QB-100FB-YQ-01T be used without the QB-100FB-YS-01T space adapter?

QB-100FB-YQ-01T may be used without QB-100FB-YS-01T only if mechanical clearance and coplanarity between QB-100FB-EA-01T and QB-100FB-NQ-01T are fully satisfied. However, Section 2.4.2 of the QB-RL78G14 manual states "Mounting YQ to NQ" assumes use with space adapters, and Table 1-3 confirms QB-100FB-YS-01T is supplied with QB-100FB-YQ-01T in full kits. Omitting it risks misalignment or stress on solder joints.

Does QB-100FB-YQ-01T have electrical ratings such as voltage or current?

No - QB-100FB-YQ-01T has no published electrical ratings because it is a passive mechanical interface, not an electronic component. Signal voltage/current limits are determined entirely by the connected QB-100FB-EA-01T and QB-100FB-NQ-01T components and the RL78/G14 target system's VDD range (1.6–5.5 V), per QB-RL78G14 hardware specifications. QB-100FB-YQ-01T itself conducts no power or signals independently.

Is QB-100FB-YQ-01T compatible with S-type emulator configurations?

No. QB-100FB-YQ-01T is strictly a T-type connector, as indicated by the "T" suffix per Section 1.4 Remark 6 of the QB-RL78G14 manual ("Check for 'T' or 'S' at the end of the socket product name"). S-type configurations use TC connectors (e.g., QB-32NA-TC-01S), and mixing T-type and S-type adapters violates Renesas' system configuration rules and risks physical incompatibility or damage.
