FAQ
What is the maximum operating frequency and corresponding DMIPS rating for R5F101PFAFA#V0?
The R5F101PFAFA#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects its RL78 CPU core executing instructions in a 3-stage pipeline under typical conditions, validated per Renesas benchmark methodology. The high-accuracy ±1.0% on-chip oscillator eliminates need for external crystal in many timing-tolerant applications.
Does R5F101PFAFA#V0 include data flash memory, and what is its endurance specification?
Yes, the R5F101PFAFA#V0 includes 4 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. This memory supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for robust firmware update and data logging implementations.
What power-saving modes are supported by R5F101PFAFA#V0, and what is the lowest achievable current draw?
The R5F101PFAFA#V0 supports HALT, STOP, and SNOOZE modes. Its lowest operational current is 0.57 μA in STOP mode with only RTC and LVD active - verified at VDD = 3.0 V and TA = 25°C. This enables decade-scale battery life in always-on monitoring applications without compromising timekeeping or brown-out protection.
How many analog input channels does the 10-bit ADC in R5F101PFAFA#V0 support, and are internal references available?
The R5F101PFAFA#V0 features a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and an integrated temperature sensor - both accessible only in HS (high-speed main) mode per datasheet specification. These reduce external component count in precision sensing designs.
Is R5F101PFAFA#V0 pin-compatible with other RL78/G13 devices in the same package, and what is its temperature grade?
Yes, the R5F101PFAFA#V0 is pin-compatible with all 100-pin LQFP RL78/G13 variants using the FA suffix (e.g., R5F101PGAFA#V0), sharing identical mechanical footprint and I/O mapping. Its temperature grade is A: -40°C to +85°C, designated for industrial applications - confirmed by the 'A' suffix in the part number per Renesas ordering guide.
