Product details
Overview
R5F101PFAFA#30 from Renesas is a 100-pin LQFP-0.65mm, 16 KB flash, 2 KB RAM, RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), real-time clock, 10-bit ADC (12 channels), and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101PFAFA#30 datasheet, R5F101PFAFA#30 pinout, R5F101PFAFA#30 application, or R5F101PFAFA#30 equivalent, key selection criteria include its data-flash-free architecture, -40°C to +85°C industrial temperature grade, 1.6–5.5 V supply range, and integrated low-voltage detector with 14-level programmable reset thresholds.
Technical Context
The R5F101PFAFA#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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, calendar-mode RTC with alarm and correction, and a watchdog timer driven by a dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 12-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 3-channel I²C/Simplified I²C, 2-channel UART (LIN-capable), and 2-channel CSI - all operating under HALT, STOP, and SNOOZE low-power modes with 0.57 μA RTC+LVD retention current.

FAQ
What is the flash memory configuration of the R5F101PFAFA#30?
The R5F101PFAFA#30 contains 16 KB of on-chip code flash memory and no data flash memory - distinguishing it from the R5F100x variant which includes 4 KB data flash. This configuration reduces cost and die area while maintaining full code execution capability and self-programming support via boot swap and flash shield window functions.
Does the R5F101PFAFA#30 support real-time clock functionality?
Yes, the R5F101PFAFA#30 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm interrupt generation, and hardware clock correction - all operational in STOP mode with only 0.57 μA current draw when paired with the on-chip LVD. This eliminates the need for external RTC ICs in time-critical logging applications.
What are the power supply requirements for the R5F101PFAFA#30?
The R5F101PFAFA#30 operates from a single 1.6 V to 5.5 V supply, supporting direct connection to common industrial rails (3.3 V, 5 V) and battery sources (2×AA, LiSOCl₂). Its on-chip POR and 14-level LVD ensure reliable startup and brown-out protection across this full range without external supervision circuitry.
Which communication interfaces does the R5F101PFAFA#30 provide?
The R5F101PFAFA#30 provides UART (2 channels, LIN-capable), I²C/Simplified I²C (3 channels), and CSI (2 channels) - all configurable on shared pins. It lacks USB, CAN, or Ethernet interfaces. The UART's TOOLRxD/TOOLTxD pins also support on-chip debugging, enabling firmware updates without dedicated programming headers.
Is the R5F101PFAFA#30 pin-compatible with other RL78/G13 variants?
Yes, the R5F101PFAFA#30 is pin-compatible with all 100-pin LQFP RL78/G13 variants sharing the FA suffix (e.g., R5F100PFAFA#30, R5F101PGAFA#30), including identical pin functions, electrical characteristics, and thermal pad layout - enabling drop-in replacement where data flash is not required.
