Product details
Overview
R5F100AFASP#X0 from Renesas is a 30-pin LSSOP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 4 KB data flash, 4 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for battery-powered industrial sensors and low-power HMI control panels operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100AFASP#X0 datasheet, R5F100AFASP#X0 pinout, R5F100AFASP#X0 application, or R5F100AFASP#X0 equivalent, key selection criteria include ultra-low power operation (0.57 μA in RTC+LVD mode), integrated data flash rewrite capability (1M cycles), and support for LIN-bus UART communication in compact LSSOP packaging.
Technical Context
The R5F100AFASP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, 8–16 CSI/SPI channels, and DMA controller with 2/4 channels enabling zero-wait-state transfers between SFR and RAM in just two clocks - optimized for deterministic real-time sensor data acquisition and actuator control.
