Overview
R5F100FEDFP#V0 from Renesas is a 44-pin LQFP-44, 96 KB flash, 8 KB data flash, 4 KB RAM RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F100FEDFP#V0 datasheet, R5F100FEDFP#V0 pinout, R5F100FEDFP#V0 application, or R5F100FEDFP#V0 equivalent, key selection criteria include its integrated 10-bit 26-channel ADC, dual UART/LIN support, real-time clock with calendar, 16-bit timer array, and hardware DMA for deterministic sensor data acquisition in resource-constrained embedded systems.
Technical Context
The R5F100FEDFP#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip debug, self-programming flash with boot swap, and background operation for data flash rewriting while executing code.
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, 8–16 16-bit timers, a 12-bit interval timer, and a calendar-capable real-time clock with alarm and correction functions - all configurable via dedicated SFRs and supported by hardware DMA transfers requiring only 2 clocks per 8/16-bit SFR ↔ RAM transfer.
