Product details
Overview
R5F100LEGFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), and real-time clock with calendar support - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LEGFB#30 datasheet, R5F100LEGFB#30 pinout, R5F100LEGFB#30 application, or R5F100LEGFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, industrial-grade temperature range (−40°C to +105°C), on-chip debug support, and hardware-accelerated BCD correction for metering firmware.
Technical Context
The R5F100LEGFB#30 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, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI (SPI-compatible) channels, and DMA controller with 4 channels - all accessible via configurable GPIO with N-ch open-drain, TTL input, and pull-up options across 39 usable I/O pins.
