Technical Context

The R5F64111NLG#U0 implements the R32C/100 Series CPU core with 108 basic instructions, 20 ns minimum instruction execution time at 50 MHz, and integrated multiplier, MAC unit, and 32-bit barrel shifter. Its memory architecture supports up to 4 GB address space (64 MB user-accessible), with on-chip flash programming voltage of 3.0–5.5 V and 1,000 program/erase cycles endurance.

It integrates four DMAC channels with cycle-steal transfer mode and 51 request sources, plus DMAC II triggered by peripheral interrupts for immediate/calculation-result/chain transfers. Clock generation includes main/sub oscillators, PLL, and on-chip oscillator with wait/stop low-power modes and oscillation stop detection.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F64111NLG#U0?

The R5F64111NLG#U0 operates at a maximum CPU frequency of 50 MHz with supply voltages VCC1 = VCC2 = 3.0 V to 5.5 V. Its minimum instruction execution time is 20 ns under these conditions, and it supports separate 3.0–5.5 V and 3.0 V domains for optimized analog/digital power partitioning.

Does the R5F64111NLG#U0 include hardware debug support?

Yes, the R5F64111NLG#U0 includes on-chip debug functionality compatible with standard JTAG interfaces. This enables full breakpoint, step-through, and memory inspection capabilities without external emulators, and supports on-board flash programming during development and field updates.

How many analog-to-digital converter channels does the R5F64111NLG#U0 support, and what is their resolution?

The R5F64111NLG#U0 features a 10-bit successive-approximation ADC with up to 26 input channels, including dedicated sample-and-hold circuitry. This allows simultaneous sampling of multiple analog signals - such as motor phase currents and temperature sensors - with consistent timing alignment critical for control loop stability.

What serial communication interfaces are integrated into the R5F64111NLG#U0?

The R5F64111NLG#U0 integrates nine independent UART channels (UART0–UART8), supporting asynchronous and synchronous modes. Six of these (UART0–UART6) implement I²C-bus functionality, and optional IEBus support is available on UART0–UART6 - enabling flexible connectivity to displays, sensors, and legacy industrial buses.

Is the R5F64111NLG#U0 pin-compatible with other members of the R32C/111 Group?

Yes, the R5F64111NLG#U0 shares identical pinout and peripheral mapping with all 100-pin R32C/111 Group variants, including R5F64110DFB, R5F64112NLG, and R5F64112DFB. This allows direct substitution within the same package type (TFLGA or LQFP) without PCB redesign, provided memory and temperature requirements align.
