Renesas R0E424270CFLE0

Overview

R0E424270CFLE0 from Renesas Electronics is a dedicated converter board enabling connection between the R0E001000FLX10 flexible cable and 120-pin 0.4mm pitch LQFP (PLQP0120LA-A) foot patterns, used for debugging and on-board evaluation of H8S/2400-series MCUs with on-chip flash or one-time PROM.

For engineers reviewing the R0E424270CFLE0 datasheet, R0E424270CFLE0 pinout, R0E424270CFLE0 application, or R0E424270CFLE0 equivalent, this board supports emulator interfacing, socket-based MCU evaluation, mechanical alignment via YQ-GUIDE fixtures, and repeatable connector insertion up to 50 cycles - critical for embedded development workflows requiring reliable physical interface bridging.

Technical Context

The R0E424270CFLE0 functions as a passive mechanical and electrical interface adapter - not an active IC or signal-processing device. It provides direct 1:1 pin mapping between CN1 (emulator-side flexible cable connector) and CN2 (socket-side LQFP footprint interface), with no signal conditioning, voltage translation, or logic functionality.

Its design integrates with Tokyo Eletech's YQPACK120SE and NQPACK120SE-ND socket system, supporting both debugging (via emulator cable) and on-board evaluation (with mounted MCU and optional HQPACK120SE). The board includes test points TP1–TP4 and conforms to PLQP0120LA-A mechanical specifications including 0.4mm pitch and 120-pin count.

FAQ

What is the primary function of the R0E424270CFLE0?

The R0E424270CFLE0 is a passive converter board that physically and electrically bridges the R0E001000FLX10 flexible cable from Renesas emulators to the 120-pin 0.4mm pitch LQFP (PLQP0120LA-A) footprint on user systems. It enables debugging and on-board evaluation of H8S/2400-series MCUs without requiring custom adapter design. The R0E424270CFLE0 does not process signals - it routes pins 1:1 between CN1 and CN2 connectors.

Which socket components are required to use the R0E424270CFLE0?

The R0E424270CFLE0 requires Tokyo Eletech's YQPACK120SE and NQPACK120SE-ND sockets, both included in the package. The NQPACK120SE-ND mounts directly to the user's PLQP0120LA-A footprint, the YQPACK120SE attaches atop it, and the R0E424270CFLE0 mounts onto the YQPACK120SE. Four YQ-GUIDE fixtures (also included) secure the assembly. HQPACK120SE is optional and not supplied with the R0E424270CFLE0.

Does the R0E424270CFLE0 support signal integrity features like impedance matching or ESD protection?

No - the R0E424270CFLE0 is a passive interconnect board with no active circuitry, termination resistors, or protection devices. Its traces are designed for short-distance, low-speed debug interfaces typical of H8S/2400 JTAG and on-chip debug channels. Signal integrity relies entirely on proper mechanical mounting, correct YQ-GUIDE usage, and adherence to the specified 50-cycle connector lifetime. The R0E424270CFLE0 does not include any built-in ESD protection or impedance control.

Can the R0E424270CFLE0 be used with MCUs other than the H8S/2400 series?

The R0E424270CFLE0 is mechanically and electrically optimized for the PLQP0120LA-A footprint used by H8S/2400-series devices. While physically compatible with any 120-pin 0.4mm pitch LQFP matching that land pattern, functional compatibility depends on pinout alignment and debug interface protocol support. Renesas documentation confirms its use only with H8S/2400-series MCUs - using it with other families may result in incorrect signal routing or debug failure. The R0E424270CFLE0 has no firmware or configuration to adapt to alternate architectures.

Is the R0E424270CFLE0 RoHS compliant and WEEE-regulated?

Yes - the R0E424270CFLE0 complies with the EU RoHS Directive and falls under the WEEE Directive 2002/96/EC. As stated in the User's Manual (REJ10J2099-0200 Rev.2.00), it must not be disposed of as household waste. Renesas offers a Tools Product Recycling Program in Europe for end-of-life return. Compliance documentation and material declarations for the R0E424270CFLE0 are maintained per Renesas' environmental policy and align with applicable regional regulations.
