FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the R5F100JEAFA#30?

The R5F100JEAFA#30 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) under standard test conditions. This performance level supports real-time control algorithms, communication protocol stacks, and basic GUI rendering in resource-constrained applications - all while maintaining the RL78/G13's ultra-low-power profile. The R5F100JEAFA#30 achieves this using its 3-stage pipeline CISC core and high-accuracy on-chip oscillator.

Does the R5F100JEAFA#30 include an integrated real-time clock with calendar functionality?

Yes, the R5F100JEAFA#30 integrates a full-featured real-time clock (RTC) with calendar support for years, months, days, hours, minutes, and seconds - plus alarm and clock correction functions. It operates independently in STOP mode with only 0.57 μA current draw, enabling accurate time-stamping and scheduled wake-up events without external components. This RTC is part of the R5F100JEAFA#30's standard peripheral set and requires no additional configuration beyond initialization.

How many analog input channels does the R5F100JEAFA#30 support, and what is its ADC resolution?

The R5F100JEAFA#30 features a 10-bit successive approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and on-chip temperature sensor, allowing precise measurements across its 1.6 V to 5.5 V supply range. Channel selection, conversion triggering, and result handling are fully configurable in software - a key capability built into the R5F100JEAFA#30's analog subsystem for flexible sensor interfacing.

What low-power modes are supported by the R5F100JEAFA#30, and what is the typical current consumption in STOP mode?

The R5F100JEAFA#30 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode - where only the RTC and LVD remain active - it consumes just 0.57 μA (typical) at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year operation on coin-cell batteries in remote sensing and metering applications. All power modes are accessible via software control and retain register contents and RAM data in the R5F100JEAFA#30's design.

Is the R5F100JEAFA#30 pin-compatible with other RL78/G13 variants in the same package?

Yes, the R5F100JEAFA#30 is pin-compatible with all other RL78/G13 MCUs in the 52-pin LQFP-0.65mm package (e.g., R5F100JFAFA#30, R5F100JGAFA#30), sharing identical pin functions and electrical characteristics. This allows drop-in replacement for memory or feature upgrades without PCB redesign. The R5F100JEAFA#30 maintains consistent I/O mapping, power pin locations, and debug interface placement across the family.
