Renesas R5F100FFAFP#30

Overview

R5F100FFAFP#30 from Renesas is a 44-pin LQFP, 32-bit RL78/G13 microcontroller with 96 KB flash, 4 KB data flash, 4 KB RAM, 1.6–5.5 V operation, and ultra-low-power modes (0.57 μA RTC+LVD). It integrates 10-bit ADC (12 channels), UART/LIN, I²C, SPI, 16-bit timers, RTC, and operates up to 32 MHz for industrial control and sensor interface applications.

For engineers reviewing the R5F100FFAFP#30 datasheet, R5F100FFAFP#30 pinout, R5F100FFAFP#30 application, or R5F100FFAFP#30 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm package, integrated LIN-capable UART, 12-channel 10-bit ADC with internal reference, RTC calendar function, and support for SNOOZE mode for low-power wake-up event handling.

Technical Context

The R5F100FFAFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It features dual-clock domains: high-speed main system clock (up to 32 MHz) and independent low-speed subsystem clock for RTC and LVD.

Its peripheral set includes 2 UART channels (one LIN-compliant), 3 I²C/Simplified I²C channels, 2 CSI (SPI-compatible) channels, 12 16-bit timer channels, 12-bit interval timer, and background operation (BGO) for data flash rewriting while executing code from program memory.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100FFAFP#30?

The R5F100FFAFP#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, enabling deterministic real-time response for motor control and closed-loop feedback systems. The R5F100FFAFP#30 also supports slower clock modes down to 32.768 kHz for ultra-low-power RTC operation.

Does the R5F100FFAFP#30 support LIN bus communication, and how is it implemented?

Yes, the R5F100FFAFP#30 supports LIN bus communication via one of its two UART channels, which includes hardware LIN protocol features compliant with SAE J2602. This UART channel provides automatic sync field detection, checksum calculation, and break signal generation - reducing CPU overhead during LIN frame transmission and reception. The R5F100FFAFP#30 does not require external transceivers for basic LIN node functionality.

How many analog input channels does the R5F100FFAFP#30 provide, and what ADC resolution is supported?

The R5F100FFAFP#30 provides 12 analog input channels with a 10-bit successive approximation ADC. It supports internal reference voltage (1.45 V) and includes dedicated AVREFP/AVREFM pins for external reference flexibility. The ADC operates across the full 1.6–5.5 V supply range, enabling direct sensing of industrial 4–20 mA loop signals or thermistor networks without signal conditioning.

What low-power modes are available on the R5F100FFAFP#30, and what is the lowest current consumption achievable?

The R5F100FFAFP#30 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at 25°C. HALT mode draws 66 μA per MHz of active core frequency, and SNOOZE mode allows selected peripherals (e.g., UART, ADC) to operate while CPU remains halted - ideal for interrupt-driven sensor polling with minimal wake latency. The R5F100FFAFP#30 maintains full register retention and fast wake-up (<5 μs) in all modes.

Is data flash available on the R5F100FFAFP#30, and what are its endurance and voltage requirements?

Yes, the R5F100FFAFP#30 includes 4 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical). It supports background operation (BGO), allowing code execution from main flash while data flash is being rewritten. Programming and erasure are supported across the full 1.8–5.5 V VDD range, eliminating the need for external charge pumps or voltage boosters. The R5F100FFAFP#30 uses flash shield window protection to prevent unauthorized access to stored calibration data.
