FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GFANA#W0?
The R5F104GFANA#W0 operates at up to 32 MHz with a measured performance of 44 DMIPS. This value reflects actual Dhrystone 2.1 benchmark results under typical operating conditions (VDD = 3.3 V, TA = 25°C), not theoretical peak throughput. The RL78 core achieves this with its 3-stage pipeline and optimized instruction set, making R5F104GFANA#W0 suitable for real-time control tasks where deterministic latency matters more than raw GHz.
Does the R5F104GFANA#W0 support self-programming of its code flash memory, and what security features accompany it?
Yes, the R5F104GFANA#W0 supports full self-programming of code flash memory, including boot-swap functionality for safe firmware updates and flash-shield window protection to prevent unauthorized read/write access to designated memory regions. Block erase prohibition is configurable per 1 KB sector, and the on-chip debug function remains active only when enabled via security fuse-ensuring intellectual property protection without disabling field serviceability.
How many analog input channels does the R5F104GFANA#W0's A/D converter support, and what reference options are available?
The R5F104GFANA#W0 integrates a 10-bit A/D converter with up to 20 analog input channels (ANI0–ANI19), including dedicated VCOUT0/VCOUT1 outputs for comparator feedback. Reference voltage options include external AVREFP/AVREFM pins or internal 1.45 V reference-enabling accurate ratiometric measurements without external voltage references or trimming components.
What power-saving modes are available on the R5F104GFANA#W0, and what is the lowest achievable current draw?
The R5F104GFANA#W0 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws 0.60 μA (typical) at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year operation on coin-cell batteries in applications like utility meters and environmental sensors-verified per Renesas specification R01DS0053EJ0340.
Is the R5F104GFANA#W0 pin-compatible with other RL78/G14 variants in the same 48-pin HWQFN package?
Yes, the R5F104GFANA#W0 shares identical pinout, electrical characteristics, and peripheral mapping with all RL78/G14 devices in the 48-pin HWQFN (NA) package-including R5F104GGANA#W0, R5F104GHANA#W0, and R5F104GJANA#W0. This enables drop-in replacement for flash/RAM scaling without PCB or schematic modifications, provided software accommodates memory size differences.
