Product details
Overview
R5F100GGDFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 8 KB RAM, 32 MHz max CPU speed (41 DMIPS), and industrial-grade -40°C to +105°C operation. It integrates RTC, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, 16-bit timers, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for embedded control in HVAC, motor drives, and smart sensors.
For engineers reviewing the R5F100GGDFB#V0 datasheet, R5F100GGDFB#V0 pinout, R5F100GGDFB#V0 application, or R5F100GGDFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, 128 KB code flash with self-programming, 10-bit ADC with internal reference, real-time clock with calendar function, and support for SNOOZE/STOP/HALT low-power states in industrial temperature environments.
Technical Context
The R5F100GGDFB#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It supports background data flash rewriting via BGO and includes a dedicated low-speed on-chip oscillator for watchdog timer operation independent of main clock.
Its peripheral set includes up to 16 channels of 16-bit timer, 12-bit interval timer, real-time clock with alarm and correction, 2–4 channel DMA, and multi-protocol serial interfaces - CSI (SPI-compatible), UART/LIN, and I²C - all configurable per channel for flexible system integration in resource-constrained industrial nodes.
