Product details
Overview
R5F101PFDFA#V0 from Renesas is a 100-pin LQFP-0.65mm, 16 KB flash, no data flash, industrial-grade (–40°C to +85°C) RL78/G13 16-bit MCU with 66 μA/MHz active power, 4 KB RAM, and integrated 10-bit ADC (26 channels), RTC, and UART/I²C/CSI interfaces - deployed in smart metering and industrial sensor nodes.
For engineers reviewing the R5F101PFDFA#V0 datasheet, R5F101PFDFA#V0 pinout, R5F101PFDFA#V0 application, or R5F101PFDFA#V0 equivalent, key selection criteria include its 16 KB code flash without data flash, 100-pin LQFP package, –40°C to +85°C industrial temperature grade, and support for low-power STOP/HALT modes with RTC+LVD retention at 0.57 μA.
Technical Context
The R5F101PFDFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 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 on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and a dedicated low-speed on-chip oscillator for watchdog timer operation.
It features 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, real-time clock with calendar (99-year), alarm, and clock correction, plus 3–10 I²C/Simplified I²C channels and 2–4 UART/LIN channels - all operating across 1.6–5.5 V supply range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PFDFA#V0 | Includes 4 KB data flash; same 16 KB code flash, 100-pin LQFP, D-grade temp | Supports field firmware updates and parameter logging without external EEPROM | Select when non-volatile configuration storage or OTA update capability is required |

FAQ
What is the flash memory configuration of the R5F101PFDFA#V0?
The R5F101PFDFA#V0 contains 16 KB of code flash memory and no data flash memory. This configuration is confirmed in the RL78/G13 datasheet Section 1.2 and Table 1-1, where "101" in the part number explicitly denotes absence of data flash. Applications requiring non-volatile parameter storage must use external EEPROM or leverage code flash sectors with self-programming routines.
Does the R5F101PFDFA#V0 support real-time clock functionality?
Yes, the R5F101PFDFA#V0 integrates a full-featured real-time clock (RTC) with calendar support (year/month/day/hour/min/sec), alarm interrupt, and automatic clock correction. It operates independently in STOP mode with only RTC and LVD active, consuming just 0.57 μA - enabling precise timekeeping in battery-powered applications without external RTC ICs.
What package type and pin count does the R5F101PFDFA#V0 use?
The R5F101PFDFA#V0 uses a 100-pin LQFP package with 0.65-mm pitch (RENESAS Code PLQP0100JC-A). The "FA" in the part number denotes LQFP-0.65mm, and "#V0" specifies tray packaging. Pin count is confirmed as 100 in Table 1-1 (page 12) of the RL78/G13 datasheet under "100 pins" → "100-pin plastic LQFP (14 × 20 mm, 0.65-mm pitch)".
What is the operating temperature range for the R5F101PFDFA#V0?
The R5F101PFDFA#V0 is rated for industrial operation from –40°C to +85°C (D-grade), as indicated by the "D" suffix in the RL78/G13 family designation and verified in Section 1.1 ("Operating ambient temperature") of the datasheet. It is not rated for the extended –40°C to +105°C (G-grade) range.
Can the R5F101PFDFA#V0 perform ADC conversions while in low-power mode?
No - the R5F101PFDFA#V0 requires the CPU to be active or in HALT mode for ADC operation. In STOP mode, the ADC is disabled. However, it supports SNOOZE mode, where the ADC can trigger wake-up from HALT and complete conversions autonomously before returning to low-power state, achieving effective power savings during periodic sensing.
