Product details
Overview
R5F101FDDFP#V0 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS, supports ultra-low-power modes (0.57 μA in RTC+LVD mode), and integrates 10-bit ADC (24 channels), UART/LIN, I²C, SPI, 16-bit timers, RTC, and watchdog - deployed in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101FDDFP#V0 datasheet, R5F101FDDFP#V0 pinout, R5F101FDDFP#V0 application, or R5F101FDDFP#V0 equivalent, key selection criteria include its 44-pin LQFP package, absence of on-chip data flash (per part number suffix '1'), industrial-grade -40°C to +85°C operation (D-grade), and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F101FDDFP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It uses a single 1.6–5.5 V supply and features dedicated low-speed on-chip oscillator for watchdog timer operation independent of main clock.
Its peripheral set includes up to 24-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 3 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, and 8–16 16-bit timers - all mapped to 44 physical pins with configurable N-ch open-drain I/O, TTL input buffers, and on-chip pull-up resistors for mixed-voltage interfacing (1.8/2.5/3 V).

It supports self-programming with boot swap and flash shield window functions, enabling secure firmware updates without external memory.
Does the R5F101FDDFP#V0 support hardware debugging?
Yes, the R5F101FDDFP#V0 includes on-chip debug functionality accessible via dedicated TOOLRxD and TOOLTxD pins (P11 and P12), allowing full SWD/JTAG-equivalent debugging, flash programming, and real-time trace using Renesas E2 emulator or compatible tools - no external debug probe required.
What is the operating temperature range for the R5F101FDDFP#V0?
The R5F101FDDFP#V0 is rated for industrial operation from –40°C to +85°C ('D' grade per part number suffix), validated across the full voltage range (1.6–5.5 V). It does not support the extended –40°C to +105°C 'G' grade offered in some RL78/G13 variants.
How many analog input channels does the R5F101FDDFP#V0 support?
The R5F101FDDFP#V0 supports up to 24 analog input channels for its 10-bit ADC, with selectable internal 1.45 V reference and integrated temperature sensor. Channel mapping is fixed per pin assignment in the 44-pin LQFP package, and all channels operate across the full 1.6–5.5 V supply range.
Is the R5F101FDDFP#V0 pin-compatible with other RL78/G13 devices in the same package?
Yes, the R5F101FDDFP#V0 shares identical pinout and electrical characteristics with all 44-pin LQFP RL78/G13 devices (e.g., R5F100FDDFP#V0, R5F101FAAFP#V0), enabling drop-in replacement within the same memory/peripheral configuration group - provided software accounts for differences in data flash presence or clock initialization.
