Product details
Overview
R5F100GGANA#20 from Renesas is a 48-pin HWQFN-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 HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100GGANA#20 datasheet, R5F100GGANA#20 pinout, R5F100GGANA#20 application, or R5F100GGANA#20 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-loop execution.
Technical Context
The R5F100GGANA#20 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), and 1 MB address space. It integrates dual-clock domains: high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16× 16-bit timers (with interval timer and calendar RTC), 2–4 DMA channels enabling 2-cycle transfers between SFR and RAM, and serial interfaces configured as CSI (SPI-like), UART/LIN, and I²C - all configurable per channel with independent clock sources and interrupt vectors.
