Renesas RTE0T00020KCA00000R

Overview

RTE0T00020KCA00000R from Renesas Electronics is a 20-pin (1.27-mm pitch) to 14-pin (2.54-mm pitch) connector conversion adapter for the E2 emulator, enabling physical interface compatibility between the E2 main unit and target systems using legacy 14-pin debug headers. It supports voltage ranges from 1.8 V to 5.5 V, delivers up to 200 mA power to the user system, and is rated for operation at ambient temperatures ≤35°C.

For engineers reviewing the RTE0T00020KCA00000R datasheet, RTE0T00020KCA00000R pinout, RTE0T00020KCA00000R application, or RTE0T00020KCA00000R equivalent, this adapter is essential when interfacing the E2 emulator with Renesas MCUs requiring 14-pin JTAG/SWD debug connectors - especially in legacy board bring-up, production programming, and cross-platform debug environments where header pitch mismatch would otherwise prevent connection.

Technical Context

This adapter bridges the standard 20-pin micro-header (FTSH-110-01-L-DV-K, 1.27-mm pitch) on the E2 emulator to a 14-pin 2.54-mm pitch header compatible with 3M 7614-6002 (Japan) or 2514-6002 (global). It maintains signal integrity for JTAG/SWD debug protocols without active logic or level shifting.

It operates passively within the same voltage and current envelope as the host E2 emulator: powered via TVDD from the E2 unit, supporting 1.8–5.5 V target supply rails and delivering up to 200 mA to the user system - all while conforming to Renesas' specified thermal limit of ≤35°C ambient operation.

FAQ

What is the primary function of the RTE0T00020KCA00000R?

The RTE0T00020KCA00000R is a passive mechanical conversion adapter that enables the Renesas E2 emulator (RTE0T00020KCE00000R) to connect to target systems equipped with 14-pin (2.54-mm pitch) debug headers. It maps signals between the E2's native 20-pin micro-header and the legacy 14-pin footprint without active circuitry, preserving JTAG/SWD protocol integrity for debugging and programming.

Is RTE0T00020KCA00000R compatible with E1 or E20 emulators?

No - RTE0T00020KCA00000R is explicitly designed and validated only for use with the E2 emulator (RTE0T00020KCE00000R). Its pin mapping, mechanical fit, and electrical behavior are tied to the E2's 20-pin FTSH-110-01-L-DV-K header and associated signal definitions. Compatibility with E1 or E20 emulators is not supported per Renesas documentation.

Does RTE0T00020KCA00000R provide voltage level translation?

No - RTE0T00020KCA00000R is a passive adapter with no active components or level-shifting circuitry. It relies on the E2 emulator's TVDD rail to supply compatible voltage (1.8–5.5 V) directly to the target system. Level translation must be handled externally if the target MCU operates outside the E2's supported voltage range.

Can RTE0T00020KCA00000R be used for production programming?

Yes - RTE0T00020KCA00000R is qualified for production use as part of the Renesas Flash Programmer workflow. When paired with the E2 emulator and appropriate software, it enables reliable firmware flashing and verification on 14-pin-targeted Renesas MCUs in manufacturing test and programming stations.

What are the mechanical dimensions and weight of RTE0T00020KCA00000R?

RTE0T00020KCA00000R has no standalone dimensional specification in Renesas documentation because it is a compact PCB-based adapter with minimal housing. Its form factor is defined by the mating connectors: Samtec FTSH-110-01-L-DV-K (20-pin side) and 3M 7614-6002 / 2514-6002 (14-pin side). Weight is negligible (<5 g) and not separately listed - it is included in the E2 package's total weight of 75 g (main unit only).
