Product details
Overview
R5F100FCAFP#V0 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and integrated peripherals including 12-bit RTC, 10-bit ADC (12 channels), UART/LIN, I²C, and CSI interfaces. It operates from 1.6 V to 5.5 V and delivers 41 DMIPS at 32 MHz for battery-powered industrial control and sensor node applications.
For engineers reviewing the R5F100FCAFP#V0 datasheet, R5F100FCAFP#V0 pinout, R5F100FCAFP#V0 application, or R5F100FCAFP#V0 equivalent, key selection criteria include its ultra-low-power STOP mode (0.57 μA), on-chip debug support, self-programmable flash with boot swap, and industrial-grade temperature range (−40°C to +85°C).
Technical Context
The R5F100FCAFP#V0 implements the RL78 CPU core with a 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). Its memory subsystem includes 96 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 8 KB SRAM - all accessible within a 1 MB address space.
Peripherals are tightly integrated for low-power system control: dual DMA channels enable efficient data movement with 2-clock transfers between SFR and RAM; the 12-bit interval timer and calendar RTC support precise timekeeping; and the 10-bit ADC features internal 1.45 V reference and temperature sensor for embedded sensing without external components.
