Product details
Overview
R5F101FCDFP#V0 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with no data flash memory, 64 KB code flash, 4 KB RAM, and industrial-grade operation (−40°C to +85°C). It features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), 32 MHz max CPU speed (41 DMIPS), 10-bit ADC (12 channels), and integrated peripherals including UART, I²C, CSI, 16-bit timers, RTC, and watchdog.
For engineers reviewing the R5F101FCDFP#V0 datasheet, R5F101FCDFP#V0 pinout, R5F101FCDFP#V0 application, or R5F101FCDFP#V0 equivalent, key selection criteria include its data-flash-free configuration for cost-sensitive firmware-immutable designs, LQFP-44 package compatibility with standard 0.8-mm pitch layouts, and support for battery-powered industrial sensors, motor control interfaces, and smart metering subsystems requiring deterministic real-time response and low standby current.
Technical Context
The R5F101FCDFP#V0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 μs min @ 32 MHz, 30.5 μs @ 32.768 kHz). It operates across 1.6–5.5 V and supports multiple low-power modes: HALT, STOP, and SNOOZE-enabling rapid wake-up from sub-μA states while retaining RTC and LVD functionality.
Peripherals are tightly integrated: dual UART/LIN channels, up to 10 I²C/Simplified I²C interfaces, 2–8 CSI channels, 8–16 16-bit timers, 12-bit interval timer, calendar RTC with alarm/correction, and 8/10-bit ADC with internal 1.45 V reference and temperature sensor. DMA controller (4-channel) enables zero-CPU-overhead memory transfers between SFRs and RAM.

FAQ
What is the flash memory configuration of the R5F101FCDFP#V0?
The R5F101FCDFP#V0 contains 64 KB of code flash memory and 4 KB of RAM, but no data flash memory - distinguishing it from the R5F100x series. This configuration is intended for applications where firmware parameters are static and do not require runtime updates, reducing system complexity and eliminating flash wear concerns. The R5F101FCDFP#V0 uses 1 KB erase blocks and supports self-programming for code updates only.
Does the R5F101FCDFP#V0 support LIN bus communication?
Yes, the R5F101FCDFP#V0 supports LIN bus communication through its UART peripherals, which are explicitly LIN-bus compatible per the RL78/G13 datasheet. Two UART channels are available, each configurable for LIN 2.x frame formatting, break detection, and sync field handling - enabling direct integration into automotive body electronics or industrial sub-networks without external transceivers beyond physical layer drivers.
What is the operating temperature range for the R5F101FCDFP#V0?
The R5F101FCDFP#V0 is rated for industrial operation from −40°C to +85°C, as indicated by the "D" suffix in its part numbering convention (R5F101FCDFP#V0 → "D" = Industrial grade). This specification is validated across all electrical parameters in the datasheet and applies to both DC characteristics and timing behavior, making it suitable for deployment in harsh environments such as factory floors, outdoor metering, and motor drive enclosures.
Can the R5F101FCDFP#V0 operate from a single 1.8 V supply?
Yes, the R5F101FCDFP#V0 supports operation from 1.6 V to 5.5 V, so it functions reliably at 1.8 V. At this voltage, the maximum guaranteed CPU frequency is reduced per the datasheet's voltage-frequency curve - typically up to ~16 MHz - but all peripherals including ADC (with internal 1.45 V reference), RTC, and low-power modes remain fully operational, enabling energy harvesting or coin-cell powered designs.
How many ADC input channels does the R5F101FCDFP#V0 support?
The R5F101FCDFP#V0 supports 12 analog input channels for its 8/10-bit successive-approximation ADC. Channel mapping is fixed per pin assignment in the 44-pin LQFP package - including P20 through P27 and P30 through P33 - and the ADC includes an internal 1.45 V reference and integrated temperature sensor usable in HS (high-speed main) mode. No external reference is required for basic ratiometric measurements.
