Product details
Overview
R5F2L367CNFP#31 from Renesas Electronics is a 16-bit R8C/L36C Group microcontroller featuring the R8C CPU core, 48 KB flash program memory, 6 KB RAM, and integrated LCD drive control (up to 8 COM / 32 SEG pins). It supports 52 programmable I/O ports with 8 high-current drive pins, operates at up to 20 MHz (50 ns min instruction time), and includes UART0/1/2, I²C, LIN, 10-bit ×10-channel ADC, dual 8-bit DACs, and timers RA–RG for motor control and real-time functions - deployed in appliance control panels and industrial HMI systems.
For engineers reviewing the R5F2L367CNFP#31 datasheet, R5F2L367CNFP#31 pinout, R5F2L367CNFP#31 application, or R5F2L367CNFP#31 equivalent, key selection criteria include its 64-pin LQFP package (PLQP0064KB-A), -20°C to +85°C N-grade temperature range, background operation (BGO) data flash, and hardware LIN module requiring UART0 and timer RA - critical for cost-sensitive, display-integrated embedded control designs.
Technical Context
The R5F2L367CNFP#31 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient math-intensive tasks. Its system clock generation includes four independent sources: XIN oscillator (1–20 MHz), XCIN 32-kHz crystal circuit, high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - enabling flexible power-mode transitions between standard, wait, stop, and power-off modes.
Peripheral integration centers on mixed-signal timing and interface: Timer RD provides 16-bit dual-channel PWM with complementary three-phase output (6-pin), while UART2 supports both I²C-bus mode and multiprocessor communication. The LCD controller delivers static/1/2/1/3/1/4/1/8 duty bias with integrated voltage multiplier, and the DTC enables autonomous data transfers triggered by 38 sources including ADC completion and UART receive events.
Key Specifications

Pinout & Package
Package: 64-pin LQFP (PLQP0064KB-A), 0.50 mm pitch, 10 mm × 10 mm body, exposed pad not specified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0_0/SEG0/AN4 | LCD segment 0 / analog input 4 | Shared function pin usable as LCD driver output or ADC channel - requires software configuration of port mode and AD control registers. |
