Product details
Overview
R5F100GDANA#W0 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), RTC with calendar/alarm, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GDANA#W0 datasheet, R5F100GDANA#W0 pinout, R5F100GDANA#W0 application, or R5F100GDANA#W0 equivalent, key selection criteria include its industrial-grade −40°C to +105°C operation (G suffix), 48-pin HWQFN (NA package) footprint, on-chip debug support, self-programmable flash with boot swap, and background data flash rewrite capability during program execution.
Technical Context
The R5F100GDANA#W0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with 99-year calendar and clock correction, and watchdog timer driven by dedicated low-speed oscillator.
Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timers, 2–4 DMA channels, and serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C/Simplified I²C across 3–10 channels - all configurable for mixed-signal embedded control in constrained power environments.
