FAQ

What is the maximum operating frequency and core performance of the R5F10EGDAFB#V0?

The R5F10EGDAFB#V0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 16-bit CISC core executes 86% of instructions in just 1–2 clock cycles, enabling deterministic real-time response in motor control and sensor fusion applications. The R5F10EGDAFB#V0 maintains this performance across its full industrial temperature range (−40°C to +105°C).

Does the R5F10EGDAFB#V0 support hardware-based functional safety features?

Yes, the R5F10EGDAFB#V0 includes multiple hardware safety mechanisms compliant with IEC 60730 Class B requirements: flash memory CRC calculation engine, RAM parity error detection, SFR write protection, illegal memory access monitoring, clock frequency detection, and ADC self-test capability. These features reduce software certification effort and enable robust fail-safe behavior in R5F10EGDAFB#V0-based appliance and industrial controllers.

How many analog input channels does the R5F10EGDAFB#V0 support, and what is their resolution and speed?

The R5F10EGDAFB#V0 integrates a 12-bit successive approximation register (SAR) ADC with up to 28 configurable analog input channels (ANI0–ANI30, excluding gaps). It achieves a 3.375 µs conversion time and operates down to 1.6 V supply voltage. An internal 1.45 V reference and on-chip temperature sensor are included, making the R5F10EGDAFB#V0 suitable for precision environmental monitoring without external reference components.

What low-power modes are available on the R5F10EGDAFB#V0, and what is the lowest achievable current draw?

The R5F10EGDAFB#V0 offers four primary low-power modes: Snooze (0.6 mA with ADC active), Stop (0.23 µA with RAM retained), Halt (0.57 µA with RTC + LVD enabled), and Deep Standby (not applicable - no sub-µA mode beyond Halt). The 0.57 µA Halt mode sustains real-time clock operation and low-voltage detection while preserving critical state - essential for R5F10EGDAFB#V0 deployments in battery-powered utility meters and remote sensors.

Can the R5F10EGDAFB#V0 be used as a LIN bus slave node, and which peripheral supports this function?

Yes, the R5F10EGDAFB#V0 supports LIN 2.2 protocol as a slave node using UART2, which includes dedicated LINSEL pin control and automatic sync-break detection. UART2 is fully integrated into the interrupt controller and timer array, enabling precise timing-critical LIN frame handling. This capability is natively supported in the R5F10EGDAFB#V0 silicon - no external transceiver configuration or firmware workarounds are needed for basic LIN communication.
