Overview
R5F10BGFLNA#G5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with CAN and LIN interfaces, 48-pin LQFP package, 32 KB flash memory, 2.5–5.5 V operating voltage, and integrated 10-bit ADC. It serves as a real-time control unit in automotive body electronics and industrial sensor nodes requiring robust serial communication and low-power operation.
For engineers reviewing the R5F10BGFLNA#G5 datasheet, R5F10BGFLNA#G5 pinout, R5F10BGFLNA#G5 application, or R5F10BGFLNA#G5 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed CAN/LIN timing compliance, and cross-referenced alternatives for automotive-grade embedded control design.
Technical Context
The R5F10BGFLNA#G5 implements the RL78 CPU core with 1.25 DMIPS/MHz performance, supporting both CAN 2.0B (up to 1 Mbps) and LIN 2.2/SAE J2602 (up to 20 kbps) on dedicated hardware peripherals. Its on-chip voltage regulator enables single-supply operation, and the 10-bit ADC features 12 input channels with programmable sampling time and scan mode.
It integrates a 15-channel event link controller for deterministic peripheral synchronization, a real-time clock with calendar function, and 16-bit timer arrays (TMR00–TMR03) supporting PWM generation, input capture, and interval timing-enabling precise motor control and sensor signal conditioning without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10BGLLNA#G5 | Same 48-pin LQFP package, identical CAN/LIN peripherals, but 48 KB flash and 4 KB RAM. | Preferred for designs requiring larger firmware image size or extended data logging buffers. | Select when firmware complexity exceeds 32 KB or real-time data buffering needs exceed 2.5 KB. |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB flash, AEC-Q100 Grade 1, but no native LIN controller - requires software emulation or external LIN transceiver. | Suitable for higher-performance automotive applications where CAN FD and functional safety (ASIL-B) are mandatory. | Choose only if ASIL-B certification, CAN FD, or >24 MHz real-time throughput is required - adds BOM cost and software overhead. |
Compared with R5F10BGFLNA#G5, R5F10BGLLNA#G5 offers scalable memory while maintaining pin and peripheral compatibility, whereas SPC560B50L5 trades LIN hardware integration for higher compute headroom and safety certification - making it appropriate only for next-tier automotive ECUs beyond basic body control.
