Product details
Overview
R5F100GADFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock for embedded control in HVAC, motor drives, and industrial sensors.
For engineers reviewing the R5F100GADFB#V0 datasheet, R5F100GADFB#V0 pinout, R5F100GADFB#V0 application, or R5F100GADFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, G-grade temperature range (–40°C to +105°C), integrated data flash with 1M rewrite cycles, and RL78 CPU core with 3-stage pipeline and sub-μA STOP/HALT modes.
Technical Context
The R5F100GADFB#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog/RTC.
Its peripheral set includes 8–16 × 16-bit timers, 1 × 12-bit interval timer, 1 × calendar RTC with alarm/correction, 1 × hardware watchdog, and 2–4-channel DMA supporting 2-cycle transfers between SFR and RAM.
