Product details
Overview
R5F10DSKJFB#X6G from Renesas Electronics is a 16-bit RL78/D1A microcontroller in 128-pin LQFP package, featuring 512 KB flash memory, 32 KB RAM, and integrated CAN 2.0B controller (2 channels), operating at up to 32 MHz with 1.8–5.5 V supply. It targets automotive body control modules requiring functional safety support, real-time motor control, and robust communication.
For engineers reviewing the R5F10DSKJFB#X6G datasheet, R5F10DSKJFB#X6G pinout, R5F10DSKJFB#X6G application, or R5F10DSKJFB#X6G equivalent, this page delivers verified technical context, validated pin functions, confirmed CAN timing parameters, exact package mapping, and two field-validated alternative MCUs for automotive-grade embedded design.
Technical Context
The R5F10DSKJFB#X6G implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions including multiply/divide and bit manipulation. It integrates dual CAN controllers compliant with ISO 11898-1:2015, each with 32 message objects, programmable bit timing, and loopback self-test mode.
On-chip peripherals include 12-bit ADC (24 channels, 1.0 μs conversion), 16-bit timer arrays (8 channels), RTC with calendar function, and hardware LIN bus interface. Power management supports four low-power modes (HALT, STOP, SNOOZE, DEEPSTOP) with wake-up latency as low as 3.5 μs from HALT.
Key Specifications
