Product details
Overview
R5F100MFGFB#V0 from Renesas is an RL78/G13 80-pin, 5 V-tolerant 16-bit microcontroller with 128 KB flash memory, 8 KB data flash, 12 KB RAM, and integrated real-time clock (RTC), A/D converter, UART, I²C, and SPI interfaces - deployed in industrial motor control, sensor nodes, and smart metering systems.
For engineers reviewing the R5F100MFGFB#V0 datasheet, R5F100MFGFB#V0 pinout, R5F100MFGFB#V0 application, or R5F100MFGFB#V0 equivalent, key selection criteria include ultra-low-power operation (0.57 μA in RTC+LVD mode), 32 MHz max CPU speed, 10-bit A/D with up to 26 channels, and LFQFP-80 (12 × 12 mm, 0.5 mm pitch) package compatibility with industrial temperature range (−40°C to +105°C).
Technical Context
The R5F100MFGFB#V0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting variable instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power management including HALT, STOP, and SNOOZE low-power modes, plus a dedicated low-speed on-chip oscillator for watchdog timer operation.
It features a 16-bit timer array (16 channels), 12-bit interval timer, calendar-based RTC with alarm and clock correction, and background operation (BGO) for data flash rewriting while executing code from program memory - enabling robust firmware updates without halting system operation.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100MFGFB#V0?
The R5F100MFGFB#V0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This speed is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and −20°C to +85°C. The RL78 CPU core's 3-stage pipeline enables deterministic real-time execution critical for motor control and sensor sampling loops.
Does the R5F100MFGFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100MFGFB#V0 supports full self-programming with boot swap and flash shield window functions. These features allow safe field firmware updates without erasing critical configuration data. The 1 KB flash block size and security lock prevent unauthorized rewrite of protected sectors - essential for certified industrial and metering applications.
What analog peripherals are integrated into the R5F100MFGFB#V0?
The R5F100MFGFB#V0 integrates a 10-bit A/D converter with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. It also supports differential input modes and scan sequencing - enabling simultaneous multi-sensor acquisition in smart metering and condition monitoring systems without external signal conditioning.
How does the R5F100MFGFB#V0 manage ultra-low-power operation in battery-backed applications?
The R5F100MFGFB#V0 achieves 0.57 μA in STOP mode with only RTC and LVD active - sufficient to maintain accurate timekeeping and brown-out detection for over a decade on a CR2032 coin cell. Its SNOOZE mode allows peripheral-triggered wake-up with <;6.5 μs latency, making it ideal for intermittent-sensing wireless nodes.
Is the R5F100MFGFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 80-pin LFQFP-0.5 mm pitch package (e.g., R5F100MGAFB#V0, R5F100MHGFB#V0) share identical pinouts and electrical characteristics. This enables hardware reuse across memory and temperature variants - simplifying design scalability and reducing qualification effort for derivative products.
