Overview
R7F702300BFABA-C#BC6 from Renesas Electronics is an automotive-grade RL78/F23-series 16-bit microcontroller with 128 KB Flash, 8 KB RAM, and 12 KB data flash. It features 32 I/O lines, 4 CSI/UART/LIN interfaces, no CAN, 4 I²C channels, 25×12-bit ADC channels, and operates up to 40 MHz. It targets body control modules requiring ASIL-B-compliant timing, capacitive touch sensing, and secure boot in 105°C ambient environments.
For engineers reviewing the R7F702300BFABA-C#BC6 datasheet, R7F702300BFABA-C#BC6 pinout, R7F702300BFABA-C#BC6 application, or R7F702300BFABA-C#BC6 equivalent, this page delivers verified technical context, package mapping to PWQN0032KF-B (QFN-32), confirmed pinout, real-world automotive use cases, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The R7F702300BFABA-C#BC6 implements the RL78 CPU core with no FPU, supports 2x internal oscillators (15 kHz and 40 MHz), and integrates a 12-bit A/D converter with 25 channels plus 1×8-bit D/A converter. Its event link controller (ELC) enables hardware-triggered peripheral chaining without CPU intervention.
It includes ISO 26262-compliant safety features up to ASIL B, capacitive touch sensing support for 12 channels, and security functions including AES crypto engine (AESEA), application accelerator unit (AAU), and tamper-resistant debug lock. The device lacks CAN or external bus interface but provides LIN, CSI, UART, and I²C for distributed vehicle network communication.

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), 44 I/O, 20×12-bit ADC, no CTSU support | Lacks capacitive touch hardware; requires external touch controller for UI applications | Select when higher I/O count and QFP assembly preference outweigh touch integration needs |
| R7F124B | RL78/F24 family, 32-pin QFN (PWQN0032KF-B), 256 KB Flash, 16 KB RAM, adds CAN 2.0B interface | Enables CAN-based body network integration; larger memory supports more complex algorithms | Choose when CAN connectivity is required and additional Flash/RAM justifies cost premium |
Compared with R7F702300BFABA-C#BC6, R7F123G trades capacitive touch for higher I/O count and QFP package compatibility, while R7F124B adds CAN and doubles memory - both retain identical 32-pin QFN footprint only in R7F124B's case, making it a drop-in upgrade path where CAN is needed.
