It targets battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F100FEDFP#X0 datasheet, R5F100FEDFP#X0 pinout, R5F100FEDFP#X0 application, or R5F100FEDFP#X0 equivalent, key selection criteria include its 44-pin LQFP package, 96 KB code flash with self-programming, 10-bit ADC resolution across 24 analog inputs, and industrial-grade temperature range (−40°C to +85°C).
Technical Context
The R5F100FEDFP#X0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates dual serial interfaces - UART/LIN (2 channels) and I²C (up to 10 channels) - with hardware flow control and automatic LIN header detection.
Its power management includes on-chip POR, 14-level LVD with interrupt/reset options, HALT/STOP/SNOOZE low-power modes, and a dedicated low-speed oscillator for watchdog operation. The DMA controller supports 4 channels with 2-clock transfers between SFR and RAM.
