Product details
Overview
R5F100LCGFA#10 from Renesas is a 64-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed (41 DMIPS), and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100LCGFA#10 datasheet, R5F100LCGFA#10 pinout, R5F100LCGFA#10 application, or R5F100LCGFA#10 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), on-chip debug support, self-programmable flash with boot swap, background data flash rewriting, and hardware multiplier/divider for deterministic control math.
Technical Context
The R5F100LCGFA#10 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 uses a single 1.6–5.5 V supply and includes dedicated low-speed on-chip oscillator for watchdog and RTC operation independent of main clock domain.
Its peripheral set includes up to 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 2–4 DMA channels, and serial interfaces configurable as CSI (SPI-like), UART (LIN-capable), or I²C - all mapped to dedicated SFRs with programmable priority and interrupt vectors.
