Product details
Overview
R5F100FDDFP#X0 from Renesas is a 44-pin LQFP-44, 1.6–5.5 V, 96 KB flash, 8 KB data flash, 4 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), integrated 10-bit ADC (24 channels), real-time clock, and multiple serial interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100FDDFP#X0 datasheet, R5F100FDDFP#X0 pinout, R5F100FDDFP#X0 application, or R5F100FDDFP#X0 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +85°C), on-chip debug support, self-programmable flash with boot swap, background data flash rewriting, and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F100FDDFP#X0 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by a dedicated low-speed oscillator.
Its peripheral set includes up to 24-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN, and 2× CSI (SPI-compatible) interfaces - all configurable via register-level control without external glue logic.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F100FDDFP#X0?
The R5F100FDDFP#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS performance. At this frequency, typical active current is 66 μA per MHz - resulting in ~2.1 mA total at 32 MHz with all peripherals disabled. This value scales linearly with clock speed and enabled peripherals, and drops to 0.57 μA in STOP mode with only RTC and LVD active.
Does the R5F100FDDFP#X0 support in-system programming and secure firmware updates?
Yes, the R5F100FDDFP#X0 supports full in-system programming via its on-chip debug interface (FINE v2) and includes flash shield window and block erase prohibition features for security. It also implements boot swap functionality, allowing validated firmware images to be loaded into a secondary bank and atomically activated on reset - preventing bricking during over-the-air updates.
How many analog input channels does the R5F100FDDFP#X0 support, and what ADC resolution is available?
The R5F100FDDFP#X0 integrates a 10-bit successive approximation ADC with up to 24 configurable analog input channels. It supports internal reference voltage (1.45 V) and includes an integrated temperature sensor accessible via dedicated ADC channel ANI23. The ADC operates across the full 1.6–5.5 V supply range and supports scan mode with automatic channel sequencing.
What serial communication interfaces are integrated into the R5F100FDDFP#X0?
The R5F100FDDFP#X0 integrates three types of serial interfaces: two UART/LIN channels (supporting LIN 2.2 protocol), three I²C/Simplified I²C channels (with master/slave capability), and two CSI (Clock Synchronous Interface) modules compatible with SPI timing. All are independently configurable and support simultaneous operation without resource conflict.
Is the R5F100FDDFP#X0 qualified for industrial temperature operation, and what packaging does it use?
Yes, the R5F100FDDFP#X0 is rated for industrial ambient temperature operation from −40°C to +85°C. It is supplied in a 44-pin LQFP package (10 × 10 mm, 0.8-mm pitch), designated by the "FP" suffix and "#X0" embossed tape packaging code - ensuring compatibility with standard SMT assembly processes and reflow profiles.
