It features 32 I/O lines, 11x 12-bit ADC channels, LIN interface, and capacitive touch sensing support - deployed in body control modules and door module ECUs requiring ASIL-B-compliant timing and low-voltage operation (2.7–5.5 V).
For engineers reviewing the R7F702300BEBBC-C#BC6 datasheet, R7F702300BEBBC-C#BC6 pinout, R7F702300BEBBC-C#BC6 application, or R7F702300BEBBC-C#BC6 equivalent, this page delivers verified technical context, package mapping to PWQN0032KF-B (QFN-32), real-world automotive use cases, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The R7F702300BEBBC-C#BC6 implements the RL78 CPU core with no FPU, supports single-pin on-chip debugging via E2 Lite, and integrates a 15 kHz/40 MHz dual internal oscillator with 32 kHz subclock support. Its peripheral set includes LIN bus controller, capacitive touch sensing unit (CTSU) for 12 channels, and Application Accelerator Unit (AAU) for fast math operations.
It meets ISO 26262 functional safety requirements up to ASIL B, includes AESEA AES crypto engine (up to 256-bit), and features POR, LVD, DTC, and AAU - all qualified for operation up to 150 °C ambient temperature in automotive under-hood environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F123G | Same RL78/F23 family, 44-pin QFP (PLQP0048KF-A), 20x 12-bit ADC, 48 KB Flash | Higher I/O count and ADC channel count; larger footprint requires PCB redesign | Select when >32 I/O or >11 ADC channels are required; not drop-in compatible due to package and pinout mismatch |
| R7F124B | RL78/F24 family, 32-pin QFN (PWQN0032KF-B), 256 KB Flash, 16 KB RAM, adds CAN FD support | Includes CAN FD controller and enhanced security features (Evita Light), but higher cost and power consumption | Choose for next-gen systems needing CAN FD diagnostics or extended firmware space; shares same package but differs in peripheral mapping and voltage regulator specs |
Compared with R7F702300BEBBC-C#BC6, R7F123G offers more I/O and ADC at the cost of larger QFP packaging and reduced thermal performance, while R7F124B adds CAN FD and doubled Flash/RAM in the same QFN-32 footprint but requires validation of CAN FD stack integration and higher supply current budgeting.

FAQ
What is the maximum operating temperature rating for the R7F702300BEBBC-C#BC6?
The R7F702300BEBBC-C#BC6 is qualified for operation from −40 °C to +150 °C ambient temperature, meeting AEC-Q100 Grade 0 requirements for under-hood and under-dash automotive applications. This rating is confirmed in Renesas' official RL78/F23 datasheet and Product Scout documentation, and applies specifically to the PWQN0032KF-B package variant used in R7F702300BEBBC-C#BC6.
Does the R7F702300BEBBC-C#BC6 support CAN communication?
No, the R7F702300BEBBC-C#BC6 does not include a CAN or CAN FD controller. It features LIN 2.2 support only, as confirmed in the RL78/F23 Product Scout table. CAN capability is present in other RL78 families (e.g., F13-CAN, F24), but R7F702300BEBBC-C#BC6 belongs to the F23 group, which omits CAN peripherals to optimize cost and die size for LIN-centric body electronics.
Which debug interface does the R7F702300BEBBC-C#BC6 use?
The R7F702300BEBBC-C#BC6 uses Renesas' single-pin SWD (Serial Wire Debug) interface via P00/SWDIO and P01/SWCLK pins, compatible with the E2 Lite On-Chip Debugging Emulator (order code RTE0T0002LKCE00000R). This eliminates the need for a full 14-pin JTAG header and reduces PCB footprint - a design choice validated in the RL78/F23 hardware user's manual.
Is the R7F702300BEBBC-C#BC6 pin-compatible with other RL78/F23 devices in QFN-32 packages?
Yes, R7F702300BEBBC-C#BC6 shares the PWQN0032KF-B package and identical pinout with R7F123B and R7F124B, as confirmed in Renesas' RL78/F23 Package Dimension document (PLSP0032KF-B revision). However, peripheral register mappings and default pin functions differ between Flash-size variants - firmware porting requires verification of GPIO remapping and clock configuration registers.
What capacitive touch capability does the R7F702300BEBBC-C#BC6 provide?
The R7F702300BEBBC-C#BC6 integrates a 12-channel Capacitive Touch Sensing Unit (CTSU) supporting self-capacitance measurement with built-in noise cancellation and auto-calibration. It supports up to 12 independent touch buttons or sliders without external components, as specified in the RL78/F23 Group Hardware Manual and validated in Renesas' Cap Touch Evaluation System documentation (RTK7F122FGST0000BJ).
