Renesas QB-100FA-EA-01T

Overview

QB-100FA-EA-01T from Renesas Electronics is an exchange adapter designed for the QB-RL78G14 in-circuit emulator, enabling physical and electrical interface conversion between the emulator's YQ connector and the 100-pin T-type target connector (QB-100FA-NQ-01T) on RL78/G14-based target systems. It supports high-speed system clock emulation up to 32 MHz, operates within 1.6–5.5 V supply range, and maintains signal integrity for real-time debugging of embedded firmware.

For engineers reviewing the QB-100FA-EA-01T datasheet, QB-100FA-EA-01T pinout, QB-100FA-EA-01T application, or QB-100FA-EA-01T equivalent, this adapter is critical for establishing reliable debug connectivity between the QB-RL78G14 emulator and 100-pin LQFP-packaged RL78/G14 microcontrollers - especially when verifying timing-sensitive execution, memory access traces, or register-level behavior during firmware development.

Technical Context

The QB-100FA-EA-01T functions exclusively as a passive mechanical and electrical translation layer: it maps the 100-pin YQ connector interface (emulator side) to the 100-pin NQ target connector footprint (target board side), preserving pin-for-pin signal routing without active logic or voltage translation. Its design assumes use with the QB-RL78G14 emulator's USB-hosted debug infrastructure and requires matching space adapters (QB-100FA-YS-01T) and target connectors (QB-100FA-NQ-01T).

No onboard circuitry, power regulation, or clock generation is present. Signal integrity relies entirely on controlled-impedance FPC routing and precise alignment of mating connectors - consistent with Renesas' T-type socket architecture defined for RL78/G14 devices in 100-pin FA packages. It does not support S-type configurations or non-RL78/G14 targets.

FAQ

What is the primary function of the QB-100FA-EA-01T?

The QB-100FA-EA-01T is a passive exchange adapter that enables physical and electrical interface compatibility between the QB-RL78G14 in-circuit emulator's YQ connector and the 100-pin NQ target connector used on RL78/G14 microcontroller boards. It performs no signal conditioning or voltage translation - its role is strictly mechanical alignment and pin mapping. The QB-100FA-EA-01T ensures correct signal routing for debugging features like real-time trace, memory inspection, and breakpoint execution on RL78/G14 devices in FA packages.

Is QB-100FA-EA-01T compatible with non-RL78/G14 targets?

No. The QB-100FA-EA-01T is explicitly designed and validated only for RL78/G14 microcontrollers in 100-pin LQFP (FA) packages. Its pinout, mechanical dimensions, and signal routing are derived from Table 1-3 of the QB-RL78G14 User's Manual and do not support other device families, package types (e.g., FB, FP), or pin counts. Using QB-100FA-EA-01T with non-RL78/G14 targets may result in misalignment, open signals, or damage to connectors.

Does QB-100FA-EA-01T require external power or configuration?

No. The QB-100FA-EA-01T is a fully passive adapter with no active components, power input, or configuration interfaces. It draws no current and contains no firmware, jumpers, or DIP switches. All functionality is realized through precision-machined contacts and fixed FPC routing. Power for debugging flows from the QB-RL78G14 emulator through the YQ/NQ connection - the QB-100FA-EA-01T itself contributes no voltage regulation or clock generation.

Which additional parts are required to use QB-100FA-EA-01T?

To deploy QB-100FA-EA-01T in a functional debug setup, you must also use: QB-RL78G14 emulator unit, QB-100FA-YQ-01T YQ connector (mated to emulator), QB-100FA-NQ-01T target connector (soldered to target board), and QB-100FA-YS-01T space adapter (for height adjustment). The QB-100FA-EA-01T cannot operate standalone - it is one link in a mechanically interdependent chain defined in Renesas' T-type emulation architecture.

Can QB-100FA-EA-01T be used with S-type sockets or 48-pin devices?

No. QB-100FA-EA-01T is designated "T" in its part number and is incompatible with S-type sockets or lower-pin-count devices. Table 1-3 confirms QB-100FA-EA-01T is listed only under "100FA" and "RL78/G14" rows - no cross-reference exists for S-type variants (e.g., QB-48NA-EA-01S) or smaller packages. Attempting to mate QB-100FA-EA-01T with an S-type connector will result in physical interference and incorrect pin alignment, risking damage to both the QB-100FA-EA-01T and connected hardware.
