For engineers reviewing the R5F104FHGFP#30 datasheet, R5F104FHGFP#30 pinout, R5F104FHGFP#30 application, or R5F104FHGFP#30 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature range (G-suffix), 44-pin 0.8 mm pitch LQFP package, 128 KB code flash with security lock, and support for background data flash rewriting (BGO) and event-link controller (ELC) for deterministic peripheral triggering.
Technical Context
The R5F104FHGFP#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz low-speed mode), and includes multiply/divide/accumulate instructions with 1 MB address space. It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.
Peripheral integration includes 8-channel 16-bit Timer Array Unit (TAU), 12-bit interval timer, 10-bit ADC with internal 1.45 V reference and temperature sensor, two 8-bit D/A converters, and up to 10 I²C channels - all configurable via Event Link Controller (ELC) for hardware-triggered, latency-critical operations without CPU intervention.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104FHGFP#30?
The R5F104FHGFP#30 operates at up to 32 MHz with a measured performance of 44 DMIPS. This is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and -40°C to +105°C. The RL78 CPU core's 3-stage pipeline and optimized instruction set deliver deterministic timing critical for real-time control loops in the R5F104FHGFP#30.
Does the R5F104FHGFP#30 support background data flash rewriting (BGO), and what are the voltage requirements?
Yes, the R5F104FHGFP#30 supports background data flash rewriting (BGO), allowing CPU code execution from program memory while data flash is being rewritten. Rewriting requires VDD between 1.8 V and 5.5 V, and the data flash endurance is rated at 1,000,000 write/erase cycles (typical). This capability is essential for reliable over-the-air updates and nonvolatile parameter storage in the R5F104FHGFP#30.
What is the purpose of the REGC pin on the R5F104FHGFP#30, and how must it be connected?
The REGC pin on the R5F104FHGFP#30 is the bypass capacitor terminal for the internal voltage regulator. It must be connected to VSS via a 0.47 µF to 1.0 µF ceramic capacitor placed as close as possible to the pin. Failure to properly decouple REGC risks unstable operation, especially during low-power mode transitions or high-current peripheral activation in the R5F104FHGFP#30.
How many analog input channels does the R5F104FHGFP#30 support, and what is the ADC resolution?
The R5F104FHGFP#30 integrates a 10-bit successive-approximation ADC supporting up to 20 analog input channels (ANI0–ANI19), with selectable reference voltages including internal 1.45 V and AVREFP/AVREFM. It also includes an on-chip temperature sensor and supports simultaneous sampling in certain configurations-key for sensor fusion in the R5F104FHGFP#30.
Is the R5F104FHGFP#30 qualified for industrial temperature operation, and what is its specified range?
Yes, the R5F104FHGFP#30 carries the 'G' suffix denoting industrial temperature qualification, with a guaranteed operating ambient temperature range of -40°C to +105°C. This rating applies across all electrical specifications including flash programming, ADC accuracy, and oscillator stability-making it suitable for demanding environments like motor drives and energy meters where the R5F104FHGFP#30 is deployed.
