FAQ
What is the maximum operating frequency and corresponding performance of the R5F100CDALA#U0?
The R5F100CDALA#U0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This speed is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8 V to 5.5 V supply and –20°C to +85°C ambient conditions. The RL78 core's 3-stage pipeline enables deterministic execution critical for real-time control loops in the R5F100CDALA#U0.
Does the R5F100CDALA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100CDALA#U0 supports full in-system programming via on-chip debug interface and includes flash shield window functionality to restrict write access to designated memory regions. It also implements boot swap capability, allowing safe firmware updates by validating new code in a secondary bank before activation - a key capability for field-upgradable industrial firmware on the R5F100CDALA#U0.
How many analog input channels does the R5F100CDALA#U0 provide, and what ADC resolution is supported?
The R5F100CDALA#U0 integrates a 10-bit successive approximation ADC with up to 26 analog input channels. It supports both single-ended and differential modes, includes an internal 1.45 V reference voltage, and features an on-chip temperature sensor. These capabilities are confirmed for the R5F100CDALA#U0 in the RL78/G13 datasheet Rev.3.80, enabling direct sensor interfacing without external signal conditioning.
What low-power modes are available on the R5F100CDALA#U0, and what is the lowest achievable current draw?
The R5F100CDALA#U0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year battery operation in metering and remote monitoring applications using the R5F100CDALA#U0.
Is the R5F100CDALA#U0 pin-compatible with other RL78/G13 variants in the same WFLGA-36 package?
Yes, all RL78/G13 devices in the WFLGA-36 package - including R5F100CAALA#U0, R5F100CCALA#U0, R5F100CDALA#U0, R5F100CEALA#U0, R5F100CFALA#U0, and R5F100CGALA#U0 - share identical pinouts and electrical characteristics.
