Product details
Overview
R5F104PFAFB#10 from Renesas is a 100-pin LFQFP (0.5 mm pitch), industrial-grade RL78/G14 16-bit MCU with 96 KB flash, 5.5 KB RAM, and 4 KB data flash. It operates from 1.6–5.5 V, delivers 44 DMIPS at 32 MHz, and supports ultra-low-power modes (66 μA/MHz active, 0.60 μA RTC+LVD). It targets battery-powered industrial sensors and motor control interfaces requiring integrated analog peripherals and LIN-capable UARTs.
For engineers reviewing the R5F104PFAFB#10 datasheet, R5F104PFAFB#10 pinout, R5F104PFAFB#10 application, or R5F104PFAFB#10 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, 96 KB/4 KB/5.5 KB memory configuration, -40 to +85°C industrial temperature grade (D suffix), and support for 8-channel 10-bit ADC, dual UART/LIN, and real-time clock with calendar function.
Technical Context
The R5F104PFAFB#10 implements the RL78 CPU core with 3-stage pipeline, variable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz), and hardware multiply/divide/accumulate. It integrates a 12-bit interval timer, RTC with 99-year calendar and alarm, and watchdog timer with dedicated low-speed oscillator.
Peripheral subsystems include 8-channel 10-bit ADC (VDD-referenced, internal 1.45 V reference, temperature sensor), two 8-bit DACs (0–VDD output), up to 10 I²C channels, four UART/LIN interfaces, and eight CSI/SPI channels - all managed via Event Link Controller (ELC) for low-CPU-overhead event chaining.
