FAQ

What is the maximum operating frequency and corresponding performance of the R5F100EEANA#U0?

The R5F100EEANA#U0 operates at up to 32 MHz with a measured performance of 41 DMIPS. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 32 MHz with ±1.0% tolerance over –20°C to +85°C, eliminating need for external crystals in many applications. This frequency headroom enables responsive real-time control and efficient data processing within the 48 KB flash limit of the R5F100EEANA#U0.

Does the R5F100EEANA#U0 support in-system programming and secure firmware updates?

Yes, the R5F100EEANA#U0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features to prevent unauthorized rewriting. It implements self-programming with boot swap capability, enabling safe dual-bank firmware updates - critical for remote devices where reliability and security of the R5F100EEANA#U0's embedded code must be guaranteed.

How many analog input channels does the R5F100EEANA#U0 ADC support, and what reference options are available?

The R5F100EEANA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference voltages on AVREFP/AVREFM pins and includes an internal 1.45 V reference. The internal temperature sensor is accessible as ANI26, enabling ambient monitoring without external components - a key design advantage for compact thermal-aware systems using the R5F100EEANA#U0.

What low-power modes are available on the R5F100EEANA#U0, and what is the lowest achievable current draw?

The R5F100EEANA#U0 provides HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across the full –40°C to +85°C industrial temperature range. This ultra-low quiescent current makes the R5F100EEANA#U0 ideal for energy-harvesting and coin-cell-powered applications where multi-year operation is required.

Is the R5F100EEANA#U0 pin-compatible with other RL78/G13 variants in the same package?

Yes, all RL78/G13 devices in the 40-pin HWQFN package - including R5F100EAANA#U0 through R5F100EHANA#U0 and their R5F101x counterparts - share identical pinouts and electrical characteristics. This allows direct substitution based on memory and feature requirements without PCB redesign, simplifying inventory management and scalability for designs built around the R5F100EEANA#U0.
