Overview
R5F21368CNFP#30 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 64 KB program ROM, 6 KB RAM, and 4 × 1 KB data flash blocks supporting background operation (BGO). It operates at up to 20 MHz (VCC = 2.7–5.5 V), integrates 12-channel 10-bit ADC, dual 8-bit DACs, LIN hardware module, and six independent timer units (RA–RG) for motor control and real-time signal generation. It targets embedded control in consumer audio and office equipment.
For engineers reviewing the R5F21368CNFP#30 datasheet, R5F21368CNFP#30 pinout, R5F21368CNFP#30 application, or R5F21368CNFP#30 equivalent, key selection criteria include its 64-pin LQFP (PLQP0064KB-A) package, −20°C to +85°C industrial temperature grade, integrated LIN transceiver support via UART0+TimerRA, and BGO-enabled data flash for firmware updates without halting execution.
Technical Context
The R5F21368CNFP#30 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte, with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash at 03000h–03FFFh.
Peripheral integration includes three UART/serial interfaces (UART0–2), I²C bus (shared with SSU), 16-bit Timer RD with complementary PWM for three-phase motor drive, and DTC for autonomous data transfers triggered by 39 sources - enabling low-CPU-overhead sensor acquisition and actuator control.

What is the maximum operating frequency and supply voltage range for the R5F21368CNFP#30?
The R5F21368CNFP#30 operates at up to 20 MHz when supplied at 2.7–5.5 V, and supports reduced-frequency operation down to 5 MHz at 1.8–5.5 V. Its minimum supply voltage of 1.8 V enables compatibility with single-cell Li-ion or multi-cell alkaline systems where brownout resilience is critical.
Does the R5F21368CNFP#30 support hardware LIN communication, and how is it implemented?
Yes, the R5F21368CNFP#30 implements LIN 2.1 via dedicated hardware combining UART0 and TimerRA - eliminating need for external transceivers. The TREO pin serves as LIN TX output, while RXD1/TXD1 handle physical layer signaling, all managed by on-chip LIN protocol logic.
How does the Background Operation (BGO) function work in the R5F21368CNFP#30 data flash?
The R5F21368CNFP#30 supports BGO on its four 1-KB data flash blocks, allowing erase/write operations to proceed asynchronously while CPU executes foreground code. This enables live firmware updates, parameter storage, or calibration data logging without halting real-time tasks like motor control or audio processing.
What timer resources are available for three-phase motor control on the R5F21368CNFP#30?
Timer RD provides two 16-bit channels with four capture/compare registers, supporting complementary PWM output on six pins (TRDIOA0–TRDIOD1), reset-synchronous PWM for synchronized commutation, and triangular/sawtooth modulation - making it suitable for BLDC and PMSM inverter control without external timers.
Is the R5F21368CNFP#30 pin-compatible with other members of the R8C/36C Group?
Yes, all R8C/36C Group MCUs in the PLQP0064KB-A package - including R5F21364CNFP through R5F2136CCNFP - share identical 64-pin LQFP pinout and peripheral mapping. Firmware portability is supported across the family via memory size and feature enablement configuration.
