FAQ
What is the maximum operating frequency and associated DMIPS rating for the R5F100BAANA#W0?
The R5F100BAANA#W0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects its RL78 CPU core's 3-stage pipeline efficiency under standard benchmark conditions. The on-chip high-speed oscillator supports ±1.0% accuracy across 1.8–5.5 V and –20 to +85°C, making the R5F100BAANA#W0 suitable for timing-critical control loops without external crystal dependency.
Does the R5F100BAANA#W0 support in-system programming and secure firmware updates?
Yes, the R5F100BAANA#W0 supports full in-system programming via its on-chip debug interface and includes boot swap functionality plus a flash shield window to protect critical bootloader regions. These features allow field firmware updates without removing the device, and prevent unauthorized access to protected memory sections - essential for certified medical or industrial deployments where R5F100BAANA#W0 serves as the primary controller.
How many analog input channels does the R5F100BAANA#W0 support, and what is the ADC resolution?
The R5F100BAANA#W0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), including dedicated AVREFP/AVREFM pins. It also provides an internal 1.45 V reference and calibrated temperature sensor - all usable simultaneously. This capability makes the R5F100BAANA#W0 ideal for multi-sensor data acquisition where precision and channel count are critical, such as environmental monitoring nodes.
What low-power modes are available on the R5F100BAANA#W0, and what is the lowest achievable current draw?
The R5F100BAANA#W0 offers HALT (66 μA/MHz), STOP (0.57 μA), and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across –40 to +85°C. This ultra-low quiescent current enables multi-year operation on small batteries, directly supporting the R5F100BAANA#W0's role in maintenance-free edge sensors and portable diagnostics equipment.
Is the R5F100BAANA#W0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100BAANA#W0 is fully pin-compatible with all other 32-pin HWQFN RL78/G13 variants (e.g., R5F100BCANA#W0, R5F101BAANA#W0), sharing identical pin functions, electrical characteristics, and mechanical footprint. This allows direct substitution during design-in or production ramp - for example, upgrading to R5F100BAANA#W0's 16 KB flash variant without PCB revision, provided peripheral usage aligns with the target part's memory map.
