FAQ

What is the maximum operating frequency of the R5F100BDANA#U0?

The R5F100BDANA#U0 supports a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS performance. It also supports ultra-low-speed operation down to 32.768 kHz for RTC and low-power modes. The oscillator accuracy is ±1.0% over VDD = 1.8–5.5 V and TA = –20 to +85°C. This dual-speed capability makes the R5F100BDANA#U0 suitable for both high-performance control loops and extended battery-life applications.

Does the R5F100BDANA#U0 include an integrated data flash memory?

Yes, the R5F100BDANA#U0 includes 4 KB of on-chip data flash memory with background operation (BGO) support, enabling read/write operations while executing code from main flash. It guarantees 1,000,000 write cycles (typical) and operates across the full VDD range of 1.8–5.5 V. This eliminates the need for external EEPROM in applications requiring frequent parameter updates, such as calibration storage or event logging in the R5F100BDANA#U0-based design.

What package type and pin count does the R5F100BDANA#U0 use?

The R5F100BDANA#U0 uses a 32-pin HWQFN package (5 × 5 mm, 0.5-mm pitch) with an exposed thermal pad, designated by the "NA" suffix in the part number. This RoHS-compliant, surface-mount package supports automated assembly and offers superior thermal performance versus TSSOP alternatives. The #U0 suffix indicates tray packaging, and the device is rated for industrial temperature range (–40°C to +85°C), making the R5F100BDANA#U0 well-suited for space-constrained industrial control modules.

Can the R5F100BDANA#U0 operate from a single 1.8 V supply?

Yes, the R5F100BDANA#U0 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supply rails. At 1.8 V, it maintains full functionality including ADC (with internal 1.45 V reference), RTC, and all peripherals - though maximum clock speed is reduced per datasheet voltage-frequency curves. This wide VDD range allows direct interfacing with 1.8 V logic families and compatibility with partially discharged batteries, enhancing system robustness in the R5F100BDANA#U0 implementation.

How many analog input channels does the R5F100BDANA#U0 support?

The R5F100BDANA#U0 supports 12 analog input channels for its 10-bit successive-approximation ADC, with dedicated pins mapped to P20–P27 and additional multiplexed options. It includes an internal 1.45 V reference voltage and an on-chip temperature sensor usable in HS (high-speed main) mode. These features allow simultaneous monitoring of multiple sensors - such as thermistors, pressure transducers, or current shunts - without external signal conditioning in R5F100BDANA#U0-based measurement systems.
