FAQ

What is the maximum operating frequency and corresponding DMIPS rating for R5F104BCGFP#10?

The R5F104BCGFP#10 operates at up to 32 MHz with a measured performance of 44 DMIPS. This benchmark reflects its RL78 CPU core efficiency under typical compiler-optimized code execution, making it suitable for real-time control tasks such as motor commutation and sensor fusion where deterministic timing is required. The 32 MHz clock is derived from the high-speed on-chip oscillator or external crystal.

Does R5F104BCGFP#10 support in-system programming and secure flash protection?

Yes, R5F104BCGFP#10 supports full in-system programming via on-chip debug interface and includes flash security features such as block erase prohibition and flash shield window. These mechanisms prevent unauthorized readout or modification of code flash contents, meeting basic firmware protection requirements for industrial IP. Self-programming is enabled with boot swapping for safe firmware updates.

What analog peripherals are integrated into R5F104BCGFP#10, and what are their key specifications?

R5F104BCGFP#10 integrates a 10-bit successive-approximation ADC with 8 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. It also includes an 8-bit D/A converter with up to two output channels (0 V to VDD range) and real-time update capability. These peripherals eliminate need for external signal conditioning in many sensor interface and closed-loop control applications.

How does the Event Link Controller (ELC) in R5F104BCGFP#10 improve system responsiveness?

The Event Link Controller (ELC) in R5F104BCGFP#10 enables direct hardware-to-peripheral triggering-such as starting an ADC conversion upon a timer match or initiating a PWM update on a GPIO edge-without CPU involvement. This reduces interrupt latency to sub-microsecond levels and frees CPU cycles for higher-layer tasks, which is critical in fast-response applications like brushless DC motor control.

What is the industrial temperature grade designation for R5F104BCGFP#10, and how is it indicated in the part number?

R5F104BCGFP#10 carries the 'G' grade designation, indicating qualification for −40°C to +105°C ambient operation-suitable for demanding industrial environments including factory automation and outdoor equipment. This grade is encoded in the fifth character of the part number ('G' in R5F104BCGFP#10), confirming its extended thermal specification versus 'A' (consumer) or 'D' (industrial −40°C to +85°C) variants.
