Renesas RTE0T00020KCA10000R

Overview

RTE0T00020KCA10000R from Renesas Electronics is a 20-pin connector conversion adapter that bridges the E2 emulator's 1.27-mm pitch interface to user-system 2.54-mm pitch headers, enabling debug connectivity for Arm® and RH850 core-based microcontrollers. It supports SWD/JTAG signal mapping (TMS/SWDIO, TCK/SWCLK, TDO/SWO, TDI), includes VTREF and TEST_PIN for voltage reference and test access, and is mechanically dimensioned at 29.0 × 13.0 × 10.5 mm with height-restricted component area.

For engineers reviewing the RTE0T00020KCA10000R datasheet, RTE0T00020KCA10000R pinout, RTE0T00020KCA10000R application, or RTE0T00020KCA10000R equivalent, this adapter serves as a hardware interface enabler for embedded firmware validation, real-time debugging of automotive and industrial MCUs, and cross-platform JTAG/SWD probe integration with legacy 2.54-mm target boards.

Technical Context

The RTE0T00020KCA10000R implements passive signal routing between two standardized 20-pin debug interfaces: CN1 (1.27-mm pitch, HTST-110-01-S-DV compatible) and CN2 (2.54-mm pitch). It maps Arm®-named SWD/JTAG signals-including TMS/SWDIO, TCK/SWCLK, TDO/SWO, TDI-to corresponding RH850 debug pins (LPDCLK, PLDO, PLDI, RDY#/LPDCLKO, RES#, LPDRST#) without level shifting or buffering.

No active circuitry, power regulation, or protocol translation is present; it is a mechanical and electrical pass-through device with fixed 1:1 pin correspondence, designed exclusively for use with Renesas E2 emulators and target systems requiring physical pitch adaptation for debug cable interfacing.

FAQ

What is the primary function of the RTE0T00020KCA10000R?

The RTE0T00020KCA10000R is a passive mechanical adapter that converts the 20-pin 1.27-mm pitch connector on Renesas E2 emulator cables to a 20-pin 2.54-mm pitch header used on many user-system target boards. It enables physical and signal-level compatibility between the emulator and legacy or custom debug interfaces without modifying cables or PCBs. The RTE0T00020KCA10000R does not include active electronics or voltage translation.

Which debug protocols does the RTE0T00020KCA10000R support?

The RTE0T00020KCA10000R supports both SWD and JTAG protocols via direct pin mapping: TMS/SWDIO, TCK/SWCLK, TDO/SWO, and TDI are routed 1:1 between CN1 and CN2. It also carries auxiliary signals including VTREF, SRST#, TRST#, DBGACK, DBGRQ, and GND Detect. Protocol selection is handled by the E2 emulator and target MCU - the RTE0T00020KCA10000R itself performs no protocol interpretation or switching.

Can the RTE0T00020KCA10000R be used with non-Renesas debug probes?

The RTE0T00020KCA10000R is designed and validated for use with Renesas E2 emulators and their associated 1.27-mm pitch interface cables. While its pinout matches standard ARM 20-pin SWD/JTAG layouts, compatibility with third-party probes depends on exact signal assignment, pin 1 orientation, and voltage tolerance alignment. Renesas does not guarantee interoperability outside its E2 ecosystem, and users must verify signal mapping and mechanical fit before deployment. The RTE0T00020KCA10000R has no built-in safeguards against misconnection.

Does the RTE0T00020KCA10000R require external power or configuration?

No, the RTE0T00020KCA10000R is a fully passive adapter with no ICs, resistors, or power connections. It requires no firmware, drivers, or configuration. Power is supplied solely through the connected E2 emulator and target system - the RTE0T00020KCA10000R only routes existing signals and references. VTREF is monitored but not regulated; it reflects the target board's reference voltage back to the emulator for level detection.

What are the mechanical constraints when mounting components near the RTE0T00020KCA10000R?

The RTE0T00020KCA10000R features a designated component-mounting restriction zone where installed parts must not exceed 10 mm in height - this ensures clearance for mating connectors and prevents interference during insertion or housing integration. The adapter's overall footprint is 29.0 mm × 13.0 mm, with 20-pin connectors positioned at opposite ends. Mounting holes or standoffs are not included; secure mechanical retention relies on board-level design or external fixtures. The RTE0T00020KCA10000R is not intended for rework or repeated hot-plugging.
