FAQ

What is the maximum operating frequency of the R5F213G6CNSP#U0 and under what voltage conditions?

The R5F213G6CNSP#U0 achieves a maximum operating frequency of 20 MHz when powered at VCC = 2.7–5.5 V. At lower supply voltages (1.8–5.5 V), the maximum frequency is reduced to 5 MHz to maintain timing margin and stability. This dual-frequency specification enables flexible power-performance trade-offs in battery-operated or wide-input-voltage designs.

Does the R5F213G6CNSP#U0 support in-circuit debugging and flash reprogramming?

Yes, the R5F213G6CNSP#U0 includes on-chip debug capability and on-board flash rewrite functionality. It supports standard Renesas E8/E8a debug interfaces and allows full read/write/erase operations on both program ROM and data flash - including background operation - without requiring external programming hardware during development or field updates.

How many analog input channels does the R5F213G6CNSP#U0 ADC support, and are they multiplexed with other functions?

The R5F213G6CNSP#U0 integrates a 10-bit successive-approximation ADC with eight analog input channels (AN0–AN11, with AN2–AN4 omitted in this variant). All channels are multiplexed with GPIO pins (e.g., P0_6/AN1/DA0), and channel selection is controlled via the ADINSEL register. Sample-and-hold operation ensures accurate conversion under noisy conditions.

What clock sources are available for the R5F213G6CNSP#U0, and how are they selected?

The R5F213G6CNSP#U0 provides four clock sources: external crystal (XIN/XOUT, up to 20 MHz), 32 kHz crystal (XCIN/XCOUT), high-speed on-chip oscillator (adjustable 1–20 MHz), and low-speed on-chip oscillator (~15 kHz). Selection is managed through the CM0/CM1 system clock control registers, with automatic failover to backup sources upon oscillation stop detection.

Is the R5F213G6CNSP#U0 pin-compatible with other members of the R8C/3GC Group?

Yes, all R8C/3GC Group MCUs in the same package type - including R5F213G6CNSP#U0 (LSSOP) and R5F213G6CNNP#U0 (HWQFN) - share identical pin assignments and electrical characteristics per pin number. Peripheral register mapping and memory layout are consistent across the group, enabling hardware reuse when migrating between flash sizes or temperature grades.
