Product details
Overview
R5F100FCDFP#V0 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial control, sensor nodes, and battery-powered HMI applications.
For engineers reviewing the R5F100FCDFP#V0 datasheet, R5F100FCDFP#V0 pinout, R5F100FCDFP#V0 application, or R5F100FCDFP#V0 equivalent, key selection criteria include its integrated RTC with calendar/alarm, 10-bit 24-channel ADC with internal temperature sensor, dual UART/LIN support, and 16-bit timer suite - all operating across –40°C to +85°C industrial temperature range.
Technical Context
The R5F100FCDFP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar function, and watchdog timer driven by dedicated low-speed on-chip oscillator.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and background operation for data flash rewriting (BGO). Serial interfaces comprise up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all configurable per peripheral function mapping.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FCAFP#V0 | Same 44-pin LQFP package, 96 KB flash, but uses high-speed on-chip oscillator only (no external crystal option). | Best suited for cost-sensitive designs where ±1.0% internal oscillator accuracy suffices and external crystal footprint must be avoided. | Select when crystal-less operation is acceptable and PCB area savings outweigh tighter timing tolerance requirements. |
| R5F101FCDFP#V0 | Identical pinout and package, but lacks data flash memory (0 KB vs. 8 KB); otherwise matches core/peripheral specs. | Targeted at applications requiring only code storage and no field-upgradable parameter storage or data logging. | Choose when persistent non-volatile data storage is unnecessary - reduces cost and simplifies flash management firmware. |
Compared with R5F100FCDFP#V0, R5F100FCAFP#V0 trades external crystal support for lower BOM cost, while R5F101FCDFP#V0 removes data flash to reduce silicon area and unit price - both retain identical I/O count, timer resources, and low-power profile for drop-in layout reuse.

Does the R5F100FCDFP#V0 include an integrated temperature sensor?
Yes, the R5F100FCDFP#V0 includes an on-chip temperature sensor usable with the 10-bit ADC. It is selectable only in HS (high-speed main) mode and provides calibrated readings referenced to the internal 1.45 V bandgap voltage - enabling accurate ambient temperature monitoring without external components.
Can the R5F100FCDFP#V0 operate from a 1.8 V supply?
Yes, the R5F100FCDFP#V0 operates across 1.6 V to 5.5 V, making it fully compatible with 1.8 V systems. Its I/O ports support different-potential interfaces, allowing direct connection to 1.8 V peripherals without level-shifting circuitry - verified across the full industrial temperature range.
How many UART channels does the R5F100FCDFP#V0 support, and do they support LIN?
The R5F100FCDFP#V0 supports up to four UART channels, with UART0 and UART1 explicitly supporting LIN protocol features including break detection, sync field generation, and checksum calculation. This enables direct integration into automotive body electronics and industrial fieldbus networks without external LIN transceivers.
What debug interface does the R5F100FCDFP#V0 use, and how many pins are required?
The R5F100FCDFP#V0 uses an on-chip debug interface accessed via three dedicated TOOL pins: TOOLRxD, TOOLTxD, and TOOLCLK. This minimal 3-pin interface provides full read/write memory access, breakpoint setting, and real-time variable inspection - eliminating the need for JTAG headers or external debug probes in most development scenarios.
