Product details
Overview
R5F100GLAFB#10 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), 10-bit ADC (26 channels), and integrated real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100GLAFB#10 datasheet, R5F100GLAFB#10 pinout, R5F100GLAFB#10 application, or R5F100GLAFB#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, and hardware-accelerated multiply-accumulate for sensor signal processing.
Technical Context
The R5F100GLAFB#10 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, 1× 12-bit interval timer, 1× calendar-capable RTC with alarm/correction, 2–4 channel DMA, and multi-protocol serial interfaces - CSI (SPI-like), UART/LIN, and I²C - all configurable via register-based control without external glue logic.
