Renesas R0E424270CFKE0

Overview

R0E424270CFKE0 from Renesas Electronics is a dedicated converter board enabling connection between the R0E001000FLX10 flexible cable and 120-pin 0.5mm pitch LQFP foot patterns (PLQP0120KA-A), used for debugging and on-board evaluation of H8S/2400 Series MCUs.

For engineers reviewing the R0E424270CFKE0 datasheet, R0E424270CFKE0 application, or R0E424270CFKE0 equivalent, this board supports emulator interfacing via YQPACK120SD/NQPACK120SD socket stack-up, requires YQ-GUIDE alignment fixtures, and guarantees 50 insertion/removal cycles for reliable prototyping and validation workflows.

Technical Context

The R0E424270CFKE0 serves as a passive mechanical and electrical interface bridge-not an active IC-between Renesas H8S/2400-series emulators and target PCBs with PLQP0120KA-A footprints. It routes all 120 pins without signal conditioning, level shifting, or buffering.

It relies on Tokyo Eletech Corporation's YQPACK120SD and NQPACK120SD sockets to achieve zero-insertion-force (ZIF) mounting on user systems. Pin mapping preserves direct continuity from CN1/CN2 connectors to the underlying MCU package footprint per Table 2 in REJ10J2106-0200 Rev.2.00.

FAQ

What is the primary function of the R0E424270CFKE0?

The R0E424270CFKE0 is a passive converter board that bridges the R0E001000FLX10 flexible cable from Renesas emulators to the PLQP0120KA-A foot pattern on user PCBs. It enables physical and electrical connection for debugging and on-board evaluation of H8S/2400 Series MCUs without modifying the target board layout. The R0E424270CFKE0 itself contains no active circuitry or silicon components.

Which sockets are required to use the R0E424270CFKE0?

The R0E424270CFKE0 requires two Tokyo Eletech Corporation sockets: NQPACK120SD (mounted directly on the user system's LQFP footprint) and YQPACK120SD (stacked on top of the NQPACK120SD). Four YQ-GUIDE alignment fixtures are included to secure the stack. The R0E424270CFKE0 mounts onto the YQPACK120SD, completing the interface path to the emulator cable.

Does the R0E424270CFKE0 support signal conditioning or voltage translation?

No-the R0E424270CFKE0 provides only direct pin-to-pin continuity with no active components, resistors, capacitors, or level-shifting circuitry. All signals pass through unaltered. Any required signal conditioning, termination, or voltage translation must be implemented externally on the user system or emulator side. The R0E424270CFKE0 functions strictly as a mechanical and routing adapter.

Is the R0E424270CFKE0 compatible with other MCU families beyond H8S/2400?

No-the R0E424270CFKE0 is explicitly designed for the H8S/2400 Series and its associated emulator interface (R0E001000FLX10). Its pin mapping, mechanical dimensions, and socket compatibility are tailored to the PLQP0120KA-A footprint and H8S-specific debug protocol timing. It is not validated or intended for use with RX, RL78, or other Renesas MCU families.

What is the rated durability of the R0E424270CFKE0's connectors?

The R0E424270CFKE0's connectors are rated for 50 guaranteed insertion and removal cycles when used with the specified YQPACK120SD/NQPACK120SD socket pair and YQ-GUIDE fixtures. This rating ensures repeatability during iterative debug sessions but does not extend to continuous operational cycling. Exceeding 50 cycles may compromise contact integrity or mechanical alignment. The R0E424270CFKE0 manual explicitly states this limit in Table 1.
