Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10ALGKFB#15 | Same RL78/F13 family, 64-pin LQFP, 96 KB flash, 6 KB RAM, no LIN support | Lacks integrated LIN controller; requires external transceiver for LIN networks | Select when higher I/O count and larger memory are needed but LIN is not required. |
| SPC560B50L5 | 32-bit Power Architecture MCU, 512 KB flash, 48 KB RAM, dual CAN, no LIN | Higher performance and safety features (ASIL-B ready), but larger footprint and higher cost | Choose for ASIL-B automotive systems where LIN is replaced by CAN-based diagnostics. |
Compared with R5F10ALECKFB#15, R5F10ALGKFB#15 offers more I/O and memory but omits LIN - requiring external components for LIN networks; SPC560B50L5 delivers higher compute capability and functional safety certification but increases BOM cost and design complexity for non-safety-critical LIN nodes.

FAQ
What is the maximum operating frequency of the R5F10ALECKFB#15?
The R5F10ALECKFB#15 operates at a maximum CPU frequency of 32 MHz using its on-chip high-speed oscillator or external crystal. This frequency is sustained across the full −40 °C to +105 °C temperature range and 1.6–5.5 V supply voltage, enabling deterministic real-time response for LIN frame processing and ADC sampling in the R5F10ALECKFB#15.
Does the R5F10ALECKFB#15 support in-system programming (ISP)?
Yes, the R5F10ALECKFB#15 supports in-system programming via its single-wire debug (SWD) interface using Renesas Flash Programmer or E2 emulator tools. The R5F10ALECKFB#15's flash memory allows background operation (BGO), permitting code execution while reprogramming non-active sectors - critical for field firmware updates without system interruption.
Is the R5F10ALECKFB#15 qualified for automotive applications?
Yes, the R5F10ALECKFB#15 is qualified per AEC-Q100 Grade 2 (−40 °C to +105 °C), making it suitable for automotive body electronics including door modules, seat controls, and HVAC actuators. Its LIN interface, low-power modes, and built-in diagnostic features (LVD, WDT, POR) align with automotive functional safety requirements for non-safety-critical systems.
What LIN protocol versions does the R5F10ALECKFB#15 support?
The R5F10ALECKFB#15's integrated LIN controller complies with ISO 17987-4 (LIN 2.2A) and supports both master and slave node operation. It handles automatic header detection, checksum calculation (classic and enhanced), and schedule table management - all implemented in hardware to offload the CPU during R5F10ALECKFB#15 LIN communication.
How much SRAM is available on the R5F10ALECKFB#15, and is it retained in low-power modes?
The R5F10ALECKFB#15 includes 8 KB of on-chip SRAM, with full retention enabled in HALT mode (0.5 µA) and STOP mode (0.25 µA with RTC active). This ensures state preservation across wake-up events - essential for maintaining LIN node configuration, sensor history buffers, and real-time clock context in battery-powered applications using the R5F10ALECKFB#15.
