Renesas R5F100FGGFP#30

Overview

R5F100FGGFP#30 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 12-bit ADC (24 channels), real-time clock, UART/LIN, I²C, and SPI interfaces for embedded control in industrial sensor nodes and power management systems.

For engineers reviewing the R5F100FGGFP#30 datasheet, R5F100FGGFP#30 pinout, R5F100FGGFP#30 application, or R5F100FGGFP#30 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), integrated data flash with 1M rewrite cycles, SNOOZE mode for low-latency wake-up, and hardware multiplier/divider for deterministic math in motor control loops.

Technical Context

The R5F100FGGFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with on-chip debug, self-programming flash with boot swap, and background operation during data flash rewriting.

Power management includes HALT, STOP, and SNOOZE modes, plus an on-chip POR and 14-level LVD with interrupt/reset selection. Peripheral integration comprises up to 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 1× watchdog timer, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100FGGFP#30?

The R5F100FGGFP#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 core supports variable instruction timing - minimum execution time is 0.03125 μs at 32 MHz - enabling deterministic real-time response in motor control and sensor fusion applications where R5F100FGGFP#30 is deployed.

Does the R5F100FGGFP#30 support in-system programming and secure firmware updates?

Yes, the R5F100FGGFP#30 supports in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition functions for firmware security. Self-programming with boot swap functionality allows safe dual-bank firmware updates, and the R5F100FGGFP#30's data flash supports background operation so application code continues running during parameter writes.

What are the analog capabilities of the R5F100FGGFP#30, and how are they calibrated?

The R5F100FGGFP#30 integrates a 10-bit successive-approximation ADC with up to 24 input channels, internal 1.45 V reference voltage, and on-die temperature sensor. Calibration is supported via factory-trimmed reference values stored in ROM; users can perform single-point calibration using the internal reference or external precision source to achieve ±1 LSB integral nonlinearity across the R5F100FGGFP#30's operating range.

How does the SNOOZE mode function on the R5F100FGGFP#30, and which peripherals remain active?

SNOOZE mode on the R5F100FGGFP#30 suspends CPU operation while keeping selected peripherals active - including UART, I²C, and CSI modules - allowing them to monitor incoming data and trigger wake-up within microseconds. This enables the R5F100FGGFP#30 to maintain communication readiness with minimal power draw, making it ideal for always-on sensor gateways and LIN slave nodes where latency and energy efficiency are both critical.

What packaging and temperature grade does the R5F100FGGFP#30 carry, and how is this indicated in the part number?

The R5F100FGGFP#30 uses a 44-pin LQFP package (10 × 10 mm, 0.8-mm pitch) and is rated for industrial operation from –40°C to +105°C. This is encoded in the part number: the "G" before "GFP" denotes the industrial temperature grade (G = –40°C to +105°C), and "FP" indicates the LQFP package type per Renesas' naming convention, confirming mechanical and thermal suitability for demanding industrial environments where R5F100FGGFP#30 is specified.
