Product details
Overview
R5F100JFDFA#V0 from Renesas is a 52-pin LQFP-0.65mm 8-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, 10-bit ADC (16 channels), and real-time clock - designed for low-power industrial control, sensor nodes, and appliance HMI systems operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100JFDFA#V0 datasheet, R5F100JFDFA#V0 pinout, R5F100JFDFA#V0 application, or R5F100JFDFA#V0 equivalent, key selection criteria include ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated LIN-capable UART, hardware multiplier/divider, and 52-pin LQFP package compatibility with industrial temperature range (−40°C to +85°C).
Technical Context
The R5F100JFDFA#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for RTC/watchdog.
It supports background data flash rewriting (BGO), self-programming with boot swap and flash shield window, and DMA transfer in 2 clocks between SFR and RAM. Peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN, and 2× CSI (SPI-compatible) interfaces - all accessible within its 52-pin LQFP footprint.

FAQ
What is the maximum operating frequency and associated power consumption of the R5F100JFDFA#V0?
The R5F100JFDFA#V0 operates up to 32 MHz using its high-speed on-chip oscillator. At this frequency, active current consumption is 66 μA per MHz - resulting in approximately 2.1 mA total at 32 MHz with typical peripherals enabled. In STOP mode with only RTC and LVD active, it draws just 0.57 μA, enabling multi-year battery operation in low-duty-cycle applications.
Does the R5F100JFDFA#V0 support LIN bus communication, and which UART channel provides it?
Yes, the R5F100JFDFA#V0 supports LIN 2.2 protocol via UART0 and UART1, both featuring auto-baud detection and break signal generation required for LIN physical layer compliance. UART0 is commonly used for primary LIN communication due to its dedicated pin mapping on P11/P12, simplifying board routing in automotive body electronics designs.
How is data flash endurance and rewrite voltage specified for the R5F100JFDFA#V0?
The R5F100JFDFA#V0 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with rewrite voltage supported across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows CPU execution from program memory during data flash rewrites, ensuring deterministic real-time behavior in applications like parameter logging or firmware updates.
What debug interface does the R5F100JFDFA#V0 use, and what pins are required?
The R5F100JFDFA#V0 uses Renesas' on-chip debug interface via the TOOLRxD (P11), TOOLTxD (P12), and TOOLCLK (P13) pins - requiring only three connections for full debug visibility, flash programming, and breakpoint control. This eliminates need for JTAG headers or external debug probes in most development workflows.
Is the R5F100JFDFA#V0 qualified for industrial temperature range, and what grade letter indicates this?
Yes, the R5F100JFDFA#V0 is qualified for −40°C to +85°C industrial operation, indicated by the "D" suffix in its part numbering convention (the "D" in "JFDFA"). This grade includes enhanced screening and validation for reliability under sustained thermal stress, making it suitable for factory automation, building controls, and outdoor equipment deployments.
