FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100FCAFP#10?
The R5F100FCAFP#10 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) under standard conditions. This performance level is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and –20 to +85°C, enabling deterministic real-time control loops in industrial firmware.
Does the R5F100FCAFP#10 include integrated data flash memory, and what is its endurance specification?
Yes, the R5F100FCAFP#10 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical). It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for logging, calibration storage, and secure firmware updates in the R5F100FCAFP#10.
What low-power modes does the R5F100FCAFP#10 support, and what is its lowest current consumption?
The R5F100FCAFP#10 supports HALT, STOP, and SNOOZE modes. Its lowest active current is 66 μA/MHz in HALT mode; in STOP mode with only RTC and LVD enabled, it draws just 0.57 μA - verified across the full –40 to +85°C industrial temperature range, making it ideal for battery-backed applications.
How many analog input channels and what ADC resolution does the R5F100FCAFP#10 provide?
The R5F100FCAFP#10 features a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor, both accessible via dedicated pins (P20/P21), enabling accurate sensor measurements without external components in the R5F100FCAFP#10.
Is the R5F100FCAFP#10 pin-compatible with other RL78/G13 variants in the same LQFP-44 package?
Yes, all RL78/G13 devices in the 44-pin LQFP package (e.g., R5F100FDAFP#10, R5F100FEAFP#10) share identical pinouts and electrical characteristics. This allows drop-in replacement for memory or feature scaling - for example, upgrading to 128 KB flash without PCB redesign - provided software accommodates the specific memory map of the R5F100FCAFP#10.
