Product details
Overview
R5F100PFAFA#30 from Renesas is a 100-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 128 KB flash memory, 12 KB RAM, and 8 KB data flash. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial control and sensor interface applications requiring integrated analog peripherals and real-time clock functionality.
For engineers reviewing the R5F100PFAFA#30 datasheet, R5F100PFAFA#30 pinout, R5F100PFAFA#30 application, or R5F100PFAFA#30 equivalent, key selection criteria include its 100-pin LQFP package, 12-bit ADC with up to 26 channels, dual UART/LIN support, 16-channel 16-bit timer suite, and on-chip RTC with calendar and alarm-critical for time-stamped sensing and low-power wake-up systems.
Technical Context
The R5F100PFAFA#30 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory architecture includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO) and 1M rewrite endurance, and 12 KB on-chip RAM.
Peripherals include three I²C/Simplified I²C channels, two to four UART/LIN interfaces, two to eight CSI (SPI-compatible) channels, an 8/10-bit ADC with internal 1.45 V reference and temperature sensor, and a real-time clock with calendar, alarm, and clock correction-enabling autonomous timekeeping without external components.
