Overview
R5F21364CNFP#50 from Renesas Electronics is a 16-bit R8C CPU core MCU with 16 KB program ROM, 1.5 KB data flash (4 × 1 KB blocks), and 1.5 KB RAM in a 64-pin LQFP (PLQP0064KB-A) package. It operates at up to 20 MHz (VCC = 2.7–5.5 V), features 12-channel 10-bit ADC, dual 8-bit DACs, LIN hardware module, and background operation (BGO) for data flash writes - deployed in consumer audio equipment and office automation control systems.
For engineers reviewing the R5F21364CNFP#50 datasheet, R5F21364CNFP#50 pinout, R5F21364CNFP#50 application, or R5F21364CNFP#50 equivalent, key selection criteria include its N-version −20°C to +85°C operating range, integrated real-time clock (Timer RE), low-power wait/stop modes (down to 2.0 µA), and support for UART/I²C/SSU serial interfaces with LIN protocol acceleration.
Technical Context
The R5F21364CNFP#50 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte (00000h–FFFFFh), with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash at 03000h–03FFFh.
Peripheral integration includes Timer RD (16-bit ×2, 6-pin PWM, complementary/triangular/sawtooth modulation), Timer RC (16-bit, 3-pin PWM), and hardware LIN using Timer RA and UART0 - enabling deterministic motor control and automotive-grade communication without external transceivers.

FAQ
What is the maximum operating frequency of the R5F21364CNFP#50?
The R5F21364CNFP#50 supports a maximum operating frequency of 20 MHz when powered at 2.7–5.5 V using the XIN clock source. At lower voltages (1.8–5.5 V), it operates up to 5 MHz. The high-speed on-chip oscillator also provides adjustable frequencies without external components, making the R5F21364CNFP#50 adaptable to varying power and timing constraints.
Does the R5F21364CNFP#50 support in-circuit debugging?
Yes, the R5F21364CNFP#50 includes on-chip debug functionality compatible with Renesas E8/E8a debuggers. It supports breakpoints, watchpoints, and real-time variable monitoring without requiring external debug hardware - enabling rapid firmware development and validation directly on target hardware containing the R5F21364CNFP#50.
How many analog input channels does the R5F21364CNFP#50 have?
The R5F21364CNFP#50 integrates a 10-bit resolution A/D converter with 12 dedicated analog input channels (AN0–AN11), each supporting sample-and-hold and sweep mode conversion. These channels are mapped across P0, P1, and P3 ports, allowing simultaneous acquisition for multi-sensor applications such as temperature and voltage monitoring in the R5F21364CNFP#50-based designs.
Is the R5F21364CNFP#50 pin-compatible with other R8C/36C Group MCUs?
Yes, the R5F21364CNFP#50 shares the same 64-pin LQFP (PLQP0064KB-A) package and identical pinout with all R8C/36C Group variants in the CNFP/CNFA/CDFP/CDFA families - including R5F21365CNFP and R5F21364CDFP. This allows direct substitution within the same footprint when upgrading ROM size or temperature grade without PCB modification.
What serial communication protocols are supported by the R5F21364CNFP#50?
The R5F21364CNFP#50 supports UART0/1/2 (with UART2 configurable for I²C bus mode), synchronous serial I/O (SSU), and hardware LIN 2.0/2.1 via dedicated logic combining Timer RA and UART0. This enables mixed-protocol communication - for example, UART0 for host diagnostics, I²C for sensor networks, and LIN for actuator control - all concurrently managed by the R5F21364CNFP#50.
