It integrates 16-bit timers, 10-bit ADC (24 channels), UART/LIN, I²C, CSI, RTC, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in HVAC, motor drives, and smart sensors.

For engineers reviewing the R5F100GHGFB#10 datasheet, R5F100GHGFB#10 pinout, R5F100GHGFB#10 application, or R5F100GHGFB#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm-pitch package, 128 KB code flash with self-programming, 10-bit ADC with internal reference, LIN-capable UART, and support for SNOOZE mode wake-up via serial interface-critical for battery-powered industrial nodes.

Technical Context

The R5F100GHGFB#10 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 dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog/RTC.

Its peripheral set includes up to 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar/alarm/correction, 2× DMA channels, 16× 10-bit ADC input channels (with internal 1.45 V reference and temperature sensor), and 3× I²C/Simplified I²C interfaces-all operating across 1.6–5.5 V supply range with LVD interrupt/reset at 14 voltage levels.

FAQ

What is the maximum operating frequency and associated performance of the R5F100GHGFB#10?

The R5F100GHGFB#10 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This speed is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V supply and -20°C to +85°C ambient - enabling deterministic real-time response in motor control and communication stacks. The R5F100GHGFB#10 supports dynamic clock switching to lower frequencies for power optimization.

Does the R5F100GHGFB#10 support in-system programming and secure firmware updates?

Yes, the R5F100GHGFB#10 supports full in-system programming via its on-chip debug interface and includes boot swap functionality plus a flash shield window to protect critical bootloader sections. These features allow secure over-the-air (OTA) firmware updates without requiring external programming hardware. The R5F100GHGFB#10 also provides block-level erase prohibition to prevent accidental corruption of protected code regions.

How many analog input channels does the R5F100GHGFB#10 ADC support, and what reference options are available?

The R5F100GHGFB#10 integrates a 10-bit successive-approximation ADC with up to 24 analog input channels. It supports both external reference voltages and an internal 1.45 V reference, selectable per channel group. The internal reference enables stable ratiometric measurements independent of VDD variation - particularly valuable in battery-operated systems where supply voltage drifts over discharge cycles. The R5F100GHGFB#10 also includes an integrated temperature sensor accessible through dedicated ADC channel ANI25.

What low-power modes are available on the R5F100GHGFB#10, and what is the lowest achievable current draw?

The R5F100GHGFB#10 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD enabled, it achieves 0.57 μA typical current draw at 25°C - ideal for long-duration battery backup. SNOOZE mode allows selected peripherals (e.g., UART, CSI) to remain active and wake the CPU asynchronously, reducing wake latency in sensor-hub applications. The R5F100GHGFB#10's 66 μA/MHz active-mode efficiency further extends operational runtime in duty-cycled systems.

Is the R5F100GHGFB#10 pin-compatible with other RL78/G13 variants in the same package?

Yes, all RL78/G13 devices in the 48-pin LFQFP package (e.g., R5F100GHGFB#10, R5F101GHGFB#10, R5F100FHGFB#10) share identical pinouts and electrical characteristics. This allows hardware reuse across memory variants - for example, designing a single PCB that supports 64 KB, 96 KB, or 128 KB flash versions by changing only the BOM. The R5F100GHGFB#10 maintains full signal and power pin compatibility within this family, simplifying scalability and inventory management.
