Product details
Overview
R5F100LFAFA#10 from Renesas is a 64-pin LQFP-0.65mm, 512 KB flash, 32 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated 10-bit ADC (26 channels), RTC, and multiple serial interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LFAFA#10 datasheet, R5F100LFAFA#10 pinout, R5F100LFAFA#10 application, or R5F100LFAFA#10 equivalent, key selection criteria include its 64-pin LQFP package, 512 KB code flash with 4 KB data flash, 32 KB RAM, -40°C to +85°C industrial-grade temperature range, and support for SNOOZE mode with background data flash rewriting.
Technical Context
The R5F100LFAFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates dual DMA channels, 16-bit × 16-bit multiply-accumulate, and hardware BCD correction.
Its peripheral set includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm, 1× watchdog timer, 3× I²C/Simplified I²C channels, 2× UART/LIN, and 2× CSI (SPI-compatible) interfaces - all operating within the same low-voltage, low-power envelope.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100LFAFA#10?
The R5F100LFAFA#10 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. At this frequency, active current consumption is 66 μA per MHz - resulting in approximately 2.1 mA total at 32 MHz with all peripherals disabled. This value scales linearly with clock speed and peripheral activation, as confirmed in the R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F100LFAFA#10 support in-system programming and secure firmware updates?
Yes, the R5F100LFAFA#10 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features. Its self-programming capability enables secure firmware updates with boot swap functionality - allowing validated new firmware to be written to a secondary bank while the system runs from the primary bank, then atomically switching upon successful verification.
What are the analog input capabilities of the R5F100LFAFA#10, and does it include an internal reference?
The R5F100LFAFA#10 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage (AVREF) usable as ADC reference, and supports differential input mode using P20/ANI0 (AVREFP) and P21/ANI1 (AVREFM). Temperature sensor output is also accessible via ANI21, as specified in the RL78/G13 datasheet Section 1.1.
Can the R5F100LFAFA#10 operate from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F100LFAFA#10 supports operation from 1.6 V to 5.5 V. At 1.8 V, the RL78 core, 512 KB flash, 32 KB RAM, 10-bit ADC (with internal 1.45 V reference), RTC, and most I/O ports remain fully functional. However, high-speed oscillator operation above 8 MHz is not guaranteed below 2.7 V - so 1.8 V operation requires use of the subsystem clock (32.768 kHz) or low-speed on-chip oscillator for timing-critical functions.
What packaging and lead finish does the R5F100LFAFA#10 use, and is it RoHS compliant?
The R5F100LFAFA#10 uses a 64-pin LQFP package (12 × 12 mm, 0.65-mm pitch) with matte tin lead finish. It is fully RoHS compliant and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), requiring bake conditioning if exposed to ambient for >168 hours before reflow. The ordering code #10 indicates tray packaging per Renesas specification PLQP0064JA-A.
