FAQ
What is the maximum operating frequency and corresponding performance of the R5F104GCANA#W0?
The R5F104GCANA#W0 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0%), delivering 44 DMIPS of processing performance. Its 3-stage pipeline RL78 core achieves minimum instruction execution times of 0.03125 μs at this speed, enabling responsive real-time control in applications like motor commutation or sensor fusion where deterministic timing is critical. The R5F104GCANA#W0 maintains this performance across its full 1.6–5.5 V supply range.
Does the R5F104GCANA#W0 support in-system programming and secure firmware updates?
Yes, the R5F104GCANA#W0 supports full in-system programming via its on-chip debug interface and includes multiple security features for firmware integrity. It implements flash shield window protection, block erase prohibition, and boot swap functionality - allowing safe dual-bank updates where new firmware is written to inactive flash while the system runs from the active bank. This ensures zero-downtime field upgrades for the R5F104GCANA#W0 in deployed equipment.
How many analog input channels and what resolution does the ADC in the R5F104GCANA#W0 provide?
The R5F104GCANA#W0 integrates a 10-bit successive-approximation ADC with 16 analog input channels (ANI0–ANI15), plus two additional channels (ANI16–ANI17) shared with serial interface pins. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor, enabling direct temperature measurement without external components. The ADC supports programmable sample-and-hold timing and conversion triggers via ELC or software, making it suitable for precision sensor interfacing in the R5F104GCANA#W0.
What low-power modes are available on the R5F104GCANA#W0 and their typical current consumption?
The R5F104GCANA#W0 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.60 μA - ideal for long-duration sleep between sensor readings. HALT mode consumes 66 μA/MHz during active operation, while SNOOZE allows selected peripherals (e.g., ADC, UART) to run autonomously while the CPU remains halted. These modes are hardware-configurable and fully documented in the R5F104GCANA#W0 user's manual.
Is the R5F104GCANA#W0 pin-compatible with other RL78/G14 variants in the same package?
Yes, the R5F104GCANA#W0 is pin-compatible with all other 48-pin HWQFN RL78/G14 variants (e.g., R5F104GAANA#W0, R5F104GHANA#W0), sharing identical pin functions, electrical characteristics, and mechanical footprint. This allows scalable design reuse - for example, prototyping with the 16 KB R5F104GCANA#W0 and upgrading to 128 KB flash (R5F104GHANA#W0) without PCB revision. All share the same REGC bypass requirement and exposed die pad connection recommendation.
