Renesas R0E521174CDB00

Overview

R0E521174CDB00 from Renesas Electronics is a dedicated converter board enabling debug and on-board evaluation of R8C/18, 19, 1A, and 1B Group MCUs in 20-pin 1.778-mm-pitch SDIP (PRDP0020BA-A) footprint. It interfaces the R0E521000EPB00 emulation probe or R0E521000CPE00 compact emulator with dual PM-6-10P sockets, supporting up to 100 insertion/removal cycles at the socket interface and 50 cycles at the emulator connection.

For engineers reviewing the R0E521174CDB00 datasheet, R0E521174CDB00 pinout, R0E521174CDB00 application, or R0E521174CDB00 equivalent, this board serves as a mechanical and electrical bridge between Renesas debug hardware and user systems featuring legacy 20-pin SDIP footprints - critical for legacy R8C MCU development, firmware validation, and hardware-in-the-loop testing.

Technical Context

The R0E521174CDB00 is a passive interconnect adapter with no active circuitry, power regulation, or signal conditioning. Its design centers on precise mechanical alignment: it accepts two Mac Eight PM-6-10P 20-pin SDIP sockets and mates directly with either R0E521000EPB00 or R0E521000CPE00 via standardized FFC interface. The board includes a 150 mm FFC cable and base board R0E521000CIF00 as integral components.

All electrical connectivity is direct 1:1 pin mapping - no translation, buffering, or level shifting. Signal integrity relies entirely on the host emulator's drive capability and the user system's layout. The board supports only the native R8C/Tiny Series debug protocol over the standard Renesas E8/E8a physical interface.

FAQ

What is the primary function of the R0E521174CDB00?

The R0E521174CDB00 is a passive converter board that bridges Renesas R0E521000EPB00 or R0E521000CPE00 debug emulators to user systems equipped with 20-pin 1.778-mm-pitch SDIP footprints. It enables both debugging and on-board evaluation of R8C/18, 19, 1A, and 1B Group MCUs without modifying the target PCB layout. The R0E521174CDB00 contains no active circuitry - all signals are routed 1:1.

Which MCUs does the R0E521174CDB00 support?

The R0E521174CDB00 supports only R8C/18, R8C/19, R8C/1A, and R8C/1B Group microcontrollers packaged in the 20-pin 1.778-mm-pitch SDIP format (PRDP0020BA-A). It is not compatible with other R8C families, 32-pin variants, or non-R8C devices - compatibility is strictly limited to the specific package and debug interface defined in the R0E521174CDB00 User's Manual.

Does the R0E521174CDB00 require external power or configuration?

No, the R0E521174CDB00 is a fully passive interconnect board with no power input, voltage regulation, or configuration options. It draws no current and contains no ICs, resistors, or capacitors. Power and debug signals are delivered solely through the FFC cable from the connected R0E521000EPB00 or R0E521000CPE00 emulator. The R0E521174CDB00 functions only when mated with one of those two authorized emulators.

What is included in the R0E521174CDB00 package?

The R0E521174CDB00 package includes one base board (R0E521000CIF00), one 150 mm FFC cable, two Mac Eight PM-6-10P 20-pin SDIP sockets, and the R0E521174CDB00 User's Manual (REJ10J0848-0100). No additional cables, adapters, or software are included - full functionality requires pairing with either R0E521000EPB00 or R0E521000CPE00, which are ordered separately.

Is the R0E521174CDB00 still supported by Renesas?

The R0E521174CDB00 is a legacy development tool released in 2005 (Rev.1.00) for the discontinued R8C/Tiny Series. Renesas no longer manufactures or actively supports it, but Aetrix Electronics provides verified, traceable inventory with full documentation. For new designs, Renesas recommends migrating to RA or RX family tools; however, the R0E521174CDB00 remains essential for maintaining and servicing existing R8C-based systems.
