Overview

R5F64112NLG#U0 from Renesas Electronics is a 32-bit CISC microcontroller in the R32C/111 Group, designed for embedded control in industrial and consumer systems. It features a 50 MHz CPU core with IEEE-754 single-precision FPU, 512 KB flash + 8 KB data flash, 63 KB RAM, 9-channel UART (including I²C-bus support), 26-channel 10-bit A/D converter, and three-phase motor control timer - deployed in home appliances and office equipment requiring deterministic real-time response.

For engineers reviewing the R5F64112NLG#U0 datasheet, R5F64112NLG#U0 pinout, R5F64112NLG#U0 application, or R5F64112NLG#U0 equivalent, this page delivers verified package mapping (100-pin LGA), validated peripheral integration (DMAC II, CRC-CCITT, X-Y converter), thermal rating (-20°C to +85°C), and direct alternative part comparisons grounded in Renesas' official product grouping.

Technical Context

The R5F64112NLG#U0 implements the R32C/100 Series CPU core with 108 basic instructions, 20 ns minimum instruction execution time at 50 MHz, and hardware multiplier/accumulate unit. Its memory architecture supports up to 4 GB address space with external bus interface (8/16-bit data width, wait-state insertion, 4 chip selects) and dual-voltage operation (VCC1 = 3.0–5.5 V, VCC2 = 3.0 V to VCC1).

It integrates four clock sources (main/sub oscillators, PLL, on-chip oscillator), low-power modes (wait/stop), and interrupt handling with 261 vectors and 7 priority levels. The DMAC II subsystem enables chain transfer triggered by any peripheral interrupt, supporting immediate data, calculation result, and chained transfers without CPU intervention.

FAQ

What is the maximum operating frequency and voltage range for the R5F64112NLG#U0?

The R5F64112NLG#U0 operates at a maximum frequency of 50 MHz with VCC1 and VCC2 supplied between 3.0 V and 5.5 V (VCC1 ≥ VCC2). At 5.0 V and 50 MHz, typical active current consumption is 32 mA; in wait mode with 32.768 kHz sub-clock, it drops to 8 µA. These values are measured per Renesas R01DS0062EJ0130 Rev.1.30, Page 3.

Does the R5F64112NLG#U0 include hardware support for motor control applications?

Yes, the R5F64112NLG#U0 integrates a dedicated three-phase motor control timer using timers A1, A2, A4, and B2, with an 8-bit programmable dead-time generator. It supports two-phase encoder input (event counter mode) across three timer pairs and provides complementary U/V/W outputs - enabling direct BLDC or PMSM commutation without external logic. This is documented in Table 1.2 and Figure 1.2 of the datasheet.

How many serial interface channels does the R5F64112NLG#U0 support, and which protocols are implemented?

The R5F64112NLG#U0 supports nine asynchronous/synchronous serial interface channels (UART0–UART8). UART0–UART6 implement I²C-bus mode and Special Mode 2; IEBus is optional on UART0–UART6. UART4 and UART5 also support variable-length synchronous serial I/O. All UARTs share common register sets and interrupt resources, as specified in Tables 1.2 and 1.4.

What is the A/D converter resolution and channel count on the R5F64112NLG#U0?

The R5F64112NLG#U0 includes a 10-bit successive-approximation A/D converter with up to 26 input channels (AN_0–AN_7, AN0_0–AN0_7, AN2_0–AN2_7), integrated sample-and-hold circuitry, and flexible trigger sources including internal timers and external pins (ADTRG). This configuration is confirmed in Table 1.2 and Figure 1.2 of the R01DS0062EJ0130 datasheet.

Is on-chip debug supported for the R5F64112NLG#U0, and what interface is used?

Yes, the R5F64112NLG#U0 supports on-chip debug via the NSD (Nexus Serial Data) pin, a single-wire serial interface compatible with Renesas E1 and E20 debug emulators. NSD requires a 1–4.7 kΩ pull-up resistor to VCC1 and enables full breakpoint, watchpoint, and flash programming capabilities without dedicated JTAG pins - detailed in Table 1.11 and Section 1.5 of the datasheet.
