Product details
Overview
R5F100GGDFB#50 from Renesas is a 48-pin LFQFP, 0.5-mm pitch, industrial-grade (−40°C to +105°C) RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, and true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and on-chip debug.
For engineers reviewing the R5F100GGDFB#50 datasheet, R5F100GGDFB#50 pinout, R5F100GGDFB#50 application, or R5F100GGDFB#50 equivalent, key selection criteria include industrial temperature support, integrated data flash for parameter storage, low-power HALT/STOP/SNOOZE modes, and 48-pin LFQFP package compatibility with space-constrained embedded control designs.
Technical Context
The R5F100GGDFB#50 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 supports background data flash rewriting (BGO) and self-programming with boot swap and flash shield window functions.
Its peripheral set includes up to 16 × 16-bit timers, one real-time clock with calendar/alarm/correction, 10-bit ADC with internal 1.45 V reference and temperature sensor, and multiple serial interfaces (CSI, UART/LIN, I²C) - all operating across 1.6–5.5 V supply and −40°C to +105°C ambient.

FAQ
What is the maximum operating frequency of the R5F100GGDFB#50?
The R5F100GGDFB#50 supports up to 32 MHz operation using its high-speed on-chip oscillator with ±1.0% accuracy across −20°C to +85°C. External crystal or ceramic resonator options are also supported for higher precision timing requirements. The RL78 core maintains deterministic execution at this frequency with a 3-stage pipeline and configurable instruction timing.
Does the R5F100GGDFB#50 include an integrated temperature sensor?
Yes, the R5F100GGDFB#50 includes an integrated temperature sensor accessible via the 10-bit ADC. It is usable only in HS (high-speed main) mode and provides calibrated readings referenced to the internal 1.45 V bandgap voltage. This eliminates the need for external thermal sensors in applications like motor winding monitoring or ambient temperature compensation.
Can the R5F100GGDFB#50 execute code while rewriting data flash memory?
Yes, the R5F100GGDFB#50 supports background operation (BGO) for data flash. Instructions can be executed from program memory while simultaneously rewriting the 8 KB data flash - enabling seamless firmware updates, parameter logging, or calibration storage without interrupting real-time control tasks.
What packaging and lead pitch does the R5F100GGDFB#50 use?
The R5F100GGDFB#50 uses a 48-pin LFQFP package with 7 mm × 7 mm body size and 0.5 mm lead pitch. The "FB" suffix in the part number explicitly denotes this LFQFP variant, and the "#50" indicates embossed tape packaging - suitable for automated SMT assembly in high-volume manufacturing environments.
Is the R5F100GGDFB#50 qualified for industrial temperature operation?
Yes, the R5F100GGDFB#50 is rated for −40°C to +105°C ambient operation (G-grade), making it suitable for industrial motor drives, factory automation equipment, and outdoor energy infrastructure. This qualification is confirmed by the "G" in the fourth character position of the part number and aligns with Renesas' industrial reliability standards.
