Product details
Overview
R5F100FCAFP#50 from Renesas is a 44-pin LQFP-44, 1.6–5.5 V RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, 32 MHz max CPU speed (41 DMIPS), and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), deployed in industrial sensor nodes and battery-powered HMI control units.
For engineers reviewing the R5F100FCAFP#50 datasheet, R5F100FCAFP#50 pinout, R5F100FCAFP#50 application, or R5F100FCAFP#50 equivalent, key selection considerations include its integrated 10-bit 24-channel ADC, dual UART/LIN support, real-time clock with calendar/alarm, hardware multiplier/divider, and 44-pin LQFP package with industrial-grade –40°C to +105°C operation.
Technical Context
The R5F100FCAFP#50 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting variable instruction execution time (0.03125 μs at 32 MHz high-speed mode, 30.5 μs at 32.768 kHz subsystem clock). It integrates on-chip power-on-reset, 14-level voltage detector (LVD), and HALT/STOP/SNOOZE low-power modes.
Peripherals include up to 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock (RTC) with calendar and clock correction, 1× watchdog timer, 2–4 channel DMA, and serial interfaces: 2–4 UART/LIN, 3–10 I²C, and 2–8 CSI (SPI-compatible) channels-all configurable via dedicated SFRs and interrupt vectors.

Yes, the R5F100FCAFP#50 integrates a full-featured RTC with 99-year calendar, alarm interrupt, and automatic clock correction-operable in STOP mode with only 0.57 μA current draw. This capability is confirmed in Section 1.1 Features and Table 1-1 of the official datasheet R01DS0131EJ0380.
What are the data flash endurance and voltage range specifications for write operations on the R5F100FCAFP#50?
The R5F100FCAFP#50 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across VDD = 1.8 V to 5.5 V. Background operation (BGO) allows concurrent code execution during rewrites, as specified in Section 1.1 "Data Flash Memory" of R01DS0131EJ0380.
Is the R5F100FCAFP#50 qualified for industrial temperature operation, and what is its grade designation?
Yes, the R5F100FCAFP#50 carries the 'G' suffix indicating Industrial-grade qualification with guaranteed operation from –40°C to +105°C ambient temperature. This is explicitly defined in Figure 1-1 "Part Number, Memory Size, and Package of RL78/G13" and Table 1-1 of the R01DS0131EJ0380 datasheet.
