FAQ

What is the maximum operating frequency and corresponding performance of the R5F100PKAFA#30?

The R5F100PKAFA#30 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core uses a 3-stage pipeline and supports configurable instruction timing - from 0.03125 μs at full speed to 30.5 μs in ultra-low-speed mode using the 32.768 kHz subsystem clock. This flexibility allows dynamic trade-offs between throughput and power consumption in the R5F100PKAFA#30.

Does the R5F100PKAFA#30 support in-system programming and secure firmware updates?

Yes, the R5F100PKAFA#30 supports full in-system programming via its on-chip debug interface and includes boot swap functionality for safe dual-bank firmware updates. It also implements flash shield window protection and block erase prohibition to prevent unauthorized modification of protected code regions - essential for certified R5F100PKAFA#30 deployments in regulated environments.

How many analog input channels does the R5F100PKAFA#30 provide, and what reference options are available?

The R5F100PKAFA#30 integrates a 10-bit ADC with 24 analog input channels. It supports external reference voltages or the internal 1.45 V reference, which is factory-calibrated and temperature-compensated. The AVREFP and AVREFM pins allow differential reference configuration, enabling high-accuracy measurements critical in precision R5F100PKAFA#30 sensor applications.

Can the R5F100PKAFA#30 operate from a single-cell lithium battery without external regulation?

Yes, the R5F100PKAFA#30 operates across 1.6 V to 5.5 V, making it compatible with unregulated single-cell lithium batteries (e.g., LiSOCl₂, nominal 3.6 V, range ~2.0–3.9 V) and alkaline cells (1.0–1.6 V per cell). Its ultra-low-power STOP mode (0.57 μA) and built-in voltage detector (LVD) with 14 programmable thresholds ensure reliable operation and graceful shutdown across the full R5F100PKAFA#30 supply range.

What serial communication interfaces are integrated into the R5F100PKAFA#30?

The R5F100PKAFA#30 integrates up to four UART/LIN modules (one LIN-compliant), up to ten I²C/Simplified I²C channels, and up to eight CSI (SPI-compatible) interfaces. These are independently assignable to multiple port groups, supporting concurrent communication with displays, sensors, EEPROMs, and automotive sub-nodes - all without external protocol translators in the R5F100PKAFA#30 design.
