Product details
Overview
R5F100GEDFB#X0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit MCU with 64 KB flash, 4 KB data flash, 4 KB RAM, 10-bit ADC (26-channel), and real-time clock - designed for low-power industrial control applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100GEDFB#X0 datasheet, R5F100GEDFB#X0 pinout, R5F100GEDFB#X0 application, or R5F100GEDFB#X0 equivalent, key selection criteria include ultra-low power consumption (0.57 μA in RTC+LVD mode), integrated data flash with background operation, and support for LIN-bus UART communication in industrial temperature range (–40°C to +105°C).
Technical Context
The R5F100GEDFB#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI/SPI channels, DMA controller (4 channels), and hardware multiplier/divider - all optimized for deterministic real-time response in resource-constrained embedded systems.
