FAQ
What is the maximum operating frequency and core type of the R5F51406ADFL#10?
The R5F51406ADFL#10 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz. It achieves 204 CoreMark at this speed and includes a 5-stage pipeline, variable-length instruction set, and IEEE-754-compliant 32-bit floating-point unit. The core supports fast interrupt response and deterministic real-time execution essential for industrial control loops.
Does the R5F51406ADFL#10 include a CAN interface, and what standard does it comply with?
Yes, the R5F51406ADFL#10 integrates one RSCAN CAN module compliant with ISO11898-1 for standard and extended frame formats, supporting bit rates up to 1 Mbps. This interface is fully functional in the 48-pin LFQFP package and is supported in the RX140 Group's hardware abstraction layer (HAL) and FSP drivers. No external transceiver is required - only a physical layer driver is needed.
How many analog input channels does the 12-bit A/D converter support on the R5F51406ADFL#10?
The R5F51406ADFL#10's S12ADE 12-bit A/D converter supports 11 external analog input channels (AD00–AD10) plus one internal channel for temperature sensor readings. This count reflects the package limitation of the 48-pin variant - higher-pin-count versions support up to 18 channels. Each channel allows independent sampling time configuration and includes disconnection detection.
What low-power modes are available on the R5F51406ADFL#10, and what is the lowest typical current consumption?
The R5F51406ADFL#10 offers four low-power modes: sleep, deep sleep, software standby, and snooze. In software standby mode with HOCO 32 MHz clock active, it consumes 0.25 µA (typ.) at 25°C. Wake-up time from this mode is 6.2 µs (typ.), enabling rapid responsiveness for event-driven applications such as sensor polling or touch wake-up.
Is the R5F51406ADFL#10 pin-compatible with other members of the RX140 Group in the same package?
Yes, the R5F51406ADFL#10 is pin-compatible with all other RX140 Group MCUs in the PLQP0048KB-B (48-pin LFQFP) package, including R5F51405ADFL#30 and R5F51403ADFL#30. Pin functions, power domains, and peripheral mappings are consistent across these variants, allowing hardware reuse and firmware scalability through memory and feature differentiation.
