Overview
R5F100MGGFB#V0 from Renesas is a 80-pin LFQFP-0.5mm MCU in the RL78/G13 family, featuring 128 KB flash memory, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed (41 DMIPS), and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial control and sensor interface applications.
For engineers reviewing the R5F100MGGFB#V0 datasheet, R5F100MGGFB#V0 pinout, R5F100MGGFB#V0 application, or R5F100MGGFB#V0 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), integrated 10-bit 26-channel ADC, real-time clock with calendar/alarm, and hardware UART/SPI/I²C interfaces supporting LIN-bus and background data flash rewriting.
Technical Context
The R5F100MGGFB#V0 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline - enabling instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It supports multiple low-power modes (HALT, STOP, SNOOZE) and includes a dedicated low-speed on-chip oscillator for watchdog and RTC operation.
Its peripheral set includes up to 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar and clock correction, 2–4 channel DMA, and a 16×16-bit multiplier/32-bit divider/multiply-accumulator. The device integrates a voltage detector (LVD) with 14 selectable levels and on-chip POR for robust power management.

FAQ
What is the maximum operating temperature rating for the R5F100MGGFB#V0?
The R5F100MGGFB#V0 is rated for industrial operation from –40°C to +105°C, confirmed by its "G" suffix in the part number per Renesas' RL78/G13 ordering guide. This rating applies across the full 1.6–5.5 V supply range and is validated for all embedded peripherals including ADC, RTC, and serial interfaces.
Does the R5F100MGGFB#V0 support background data flash rewriting?
Yes, the R5F100MGGFB#V0 supports background operation (BGO) for data flash: instructions can be executed from code flash while simultaneously erasing or writing data flash memory. This capability is enabled by dedicated hardware and requires use of Renesas' Flash Self-Programming Library (R20UT2944).
What package type and pin count does the R5F100MGGFB#V0 use?
The R5F100MGGFB#V0 uses an 80-pin LFQFP package with 0.5 mm pitch (RENESAS Code PLQP0080KE-A), as specified in Table 1-1 of the RL78/G13 datasheet (R01DS0131EJ0380). The "FB" in the part number explicitly denotes LFQFP, and "#V0" indicates tray packaging.
How many ADC channels does the R5F100MGGFB#V0 support, and what is its resolution?
The R5F100MGGFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports internal 1.45 V reference voltage and temperature sensor measurement, and operates across the full 1.6–5.5 V supply range without external reference components.
Is the R5F100MGGFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes - the R5F100MGGFB#V0 shares identical pinout and electrical characteristics with all other 80-pin LFQFP RL78/G13 devices (e.g., R5F100MFAFB#V0, R5F101MGGFB#V0), as confirmed by the unified pin configuration diagrams in Section 1.3 of the datasheet. Functional differences (e.g., data flash presence) do not affect pin mapping or I/O behavior.
