Renesas R5F212L2SDFP#U0

Overview

R5F212L2SDFP#U0 from Renesas Electronics is a 14-pin small-connector conversion adapter for the E1 emulator, enabling interface between 2.54-mm pitch cables and 1.27-mm pitch system connectors. It reduces PCB footprint by replacing standard headers with compact Samtec TFM-series connectors and supports both through-hole (TFM-107-01-L-D) and SMT (TFM-107-02-L-D) mounting. Its primary role is physical signal routing in embedded development environments during debug and programming.

For engineers reviewing the R5F212L2SDFP#U0 datasheet, R5F212L2SDFP#U0 pinout, R5F212L2SDFP#U0 application, or R5F212L2SDFP#U0 equivalent, key considerations include verified pin mapping between CN1 (E1 cable) and CN2 (user-system), mechanical height clearance limits (≤5 mm around connector), and compatibility with Renesas E1 emulator interface specifications.

Technical Context

The R5F212L2SDFP#U0 serves as a passive mechanical and electrical bridge - not an active IC - translating pin assignments between two standardized 14-pin interfaces. It implements non-standard pin remapping (e.g., CN1 Pin 2 → CN2 Pins 1 & 14; CN1 Pin 12 → CN2 Pins 1 & 14), requiring board-level design adaptation.

It is designed exclusively for use with the Renesas E1 emulator user-system interface cable (R0E000010KCE00) and mandates use of specified Samtec connectors: HTST-107-01-T-DV (upper), SFM-107-02-L-D-A (lower), and either TFM-107-01-L-D (DIP) or TFM-107-02-L-D (SMT) on the target system. Rated for 50 mating cycles per connector side.

FAQ

What is the function of the R5F212L2SDFP#U0?

The R5F212L2SDFP#U0 is a passive mechanical adapter that converts the 14-pin, 2.54-mm pitch connector on the E1 emulator interface cable to a 14-pin, 1.27-mm pitch connector compatible with compact user-system layouts. It contains no active components and performs only pin translation and physical spacing adaptation - the R5F212L2SDFP#U0 enables smaller PCB footprints without altering signal functionality.

Does the R5F212L2SDFP#U0 require power or configuration?

No, the R5F212L2SDFP#U0 is a fully passive adapter with no power pins, no firmware, and no configuration options. It operates solely as a wired interconnect - all signals pass through unchanged except for remapped pin positions. The R5F212L2SDFP#U0 relies entirely on correct mechanical mating and verified pin correspondence per Table 3 in its official user manual (R20UT0162EJ0200).

Which connectors are required to use the R5F212L2SDFP#U0?

The R5F212L2SDFP#U0 requires three specific Samtec connectors: HTST-107-01-T-DV (upper), SFM-107-02-L-D-A (lower), and either TFM-107-01-L-D (through-hole) or TFM-107-02-L-D (SMT) on the user system. These are mandatory for mechanical fit and electrical continuity - the R5F212L2SDFP#U0 will not function correctly with non-specified alternatives.

Is the R5F212L2SDFP#U0 compatible with other Renesas emulators like E2 or J-Link?

No, the R5F212L2SDFP#U0 is designed exclusively for the Renesas E1 emulator and its associated interface cable (R0E000010KCE00). It does not support E2, E2 Lite, or third-party debug probes. Pin mapping, mechanical dimensions, and orientation keys are specific to E1 - using the R5F212L2SDFP#U0 with other emulators may result in misalignment or signal mismatch.

What is the maximum allowable component height near the R5F212L2SDFP#U0 on the user system?

The R5F212L2SDFP#U0 imposes a strict mechanical constraint: components mounted within a 7.5 mm radius around the user-system connector must not exceed 5 mm in height. This ensures unobstructed mating with the adapter's lower connector (CN2). This limit applies only when using TFM-107-01-L-D or TFM-107-02-L-D - the R5F212L2SDFP#U0 documentation explicitly ties this specification to those Samtec part numbers.
