Product details
Overview
R5F101FFAFP#V0 from Renesas is a 44-pin LQFP, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 4 KB data flash, 4 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (12 channels), UART/SPI/I²C interfaces, and operates from 1.6–5.5 V for industrial control panels.
For engineers reviewing the R5F101FFAFP#V0 datasheet, R5F101FFAFP#V0 pinout, R5F101FFAFP#V0 application, or R5F101FFAFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for SNOOZE mode for low-power sensor polling.
Technical Context
The R5F101FFAFP#V0 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and features a 1 MB address space with four 8-bit register banks. Its memory subsystem includes 96 KB code flash (1 KB block size), no data flash (confirmed by part number "101" designation), and 4 KB SRAM.
Peripheral integration includes two UART/LIN channels, three I²C/Simplified I²C channels, up to eight 16-bit timers, one real-time clock with calendar/alarm, and a 10-bit ADC with 12 analog inputs and internal 1.45 V reference-enabling self-contained timing, communication, and sensing in compact industrial nodes.

FAQ
Does R5F101FFAFP#V0 include on-chip data flash memory?
No, the R5F101FFAFP#V0 does not include on-chip data flash memory. The "101" in the part number explicitly denotes "data flash not provided", per Renesas' RL78/G13 ordering guide. This distinguishes it from the "100" series (e.g., R5F100FFAFP#V0), which includes 4 KB data flash. Applications requiring nonvolatile parameter storage must use external EEPROM or utilize code flash with wear-leveling firmware.
What is the operating temperature range for R5F101FFAFP#V0?
The R5F101FFAFP#V0 is rated for an operating ambient temperature range of –40°C to +85°C, corresponding to the "D" industrial grade designation in its part number structure. It is not qualified for the extended –40°C to +105°C ("G" grade) range. This makes it suitable for indoor industrial equipment, commercial HVAC systems, and consumer-grade automation devices.
Which development tools support R5F101FFAFP#V0 firmware development?
The R5F101FFAFP#V0 is fully supported by Renesas' CS+ IDE (with compiler and debugger), e² studio (Eclipse-based with GCC RL78 toolchain), and the Renesas Flash Programmer. Hardware debugging requires the E2 emulator Lite or full E2 emulator, both compatible with the 44-pin LQFP package's SWD/JTAG interface (P13/TOOLCLK, P12/TOOLTxD, P11/TOOLRxD).
Can R5F101FFAFP#V0 operate without an external crystal?
Yes, the R5F101FFAFP#V0 can operate without an external crystal. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 32 MHz with ±1.0% tolerance (VDD = 1.8–5.5 V, TA = –20 to +85°C), enabling reliable UART, LIN, and I²C communication directly from internal clock sources-reducing BOM cost and PCB footprint.
How many analog input channels does R5F101FFAFP#V0 support?
The R5F101FFAFP#V0 supports 12 analog input channels for its 10-bit ADC, as confirmed in the RL78/G13 datasheet section "1.1 Features" under "A/D converter". These channels are mapped to dedicated pins including P20–P27 and P30–P33, and support internal reference (1.45 V) and temperature sensor readout for system health monitoring.
