FAQ

What is the maximum operating frequency and CPU performance of the R5F562N7BDFB#V0?

The R5F562N7BDFB#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS using the 32-bit RX CPU core. Its single-cycle 32×32 multiply, 64-bit accumulator, and IEEE-754 floating-point unit enable deterministic real-time computation for motor control and sensor fusion tasks within the R5F562N7BDFB#V0's instruction set architecture.

Does the R5F562N7BDFB#V0 support Ethernet and USB simultaneously?

Yes, the R5F562N7BDFB#V0 integrates both an Ethernet MAC (10/100 Mbps with MII/RMII) and a USB 2.0 Full-Speed host/function/OTG module. These operate concurrently using dedicated DMA channels (EDMAC and UDC), allowing the R5F562N7BDFB#V0 to serve as a dual-interface edge node - for example, bridging fieldbus data over Ethernet while supporting USB-based configuration or firmware updates.

What are the analog capabilities of the R5F562N7BDFB#V0?

The R5F562N7BDFB#V0 features a 12-bit × 8-channel ADC with 1.0 µs conversion time at 50 MHz PCLK, plus two independent 10-bit DACs with 0 V to VREFH output range. It supports sample-and-hold, hardware-triggered conversions (via MTU/TMR), and AD-converted value addition mode - making the R5F562N7BDFB#V0 suitable for precision analog monitoring and closed-loop control in industrial environments.

Is the R5F562N7BDFB#V0 pin-compatible with other RX62N Group MCUs?

Yes, the R5F562N7BDFB#V0 in LQFP144 (PLQP0144KA-A) shares identical pinout and footprint with other RX62N Group members in the same package, including R5F562N8BDFB#V0 and R5F562N7ADFB#V0. This enables direct substitution for memory or feature scaling without PCB redesign - provided external circuitry aligns with the specific variant's peripheral enablement (e.g., CAN presence).

What low-power modes does the R5F562N7BDFB#V0 support?

The R5F562N7BDFB#V0 provides four low-power modes: Sleep, All-Module Clock Stop, Software Standby, and Deep Software Standby with RTC. In Deep Software Standby, it consumes minimal current while retaining SRAM content and waking via RTC alarm or external interrupt - a key capability for battery-powered R5F562N7BDFB#V0 deployments in remote monitoring nodes.
