Renesas R5F2L36CCDFP#31

Overview

R5F2L36CCDFP#31 from Renesas is a 16-bit R8C/L36C Group microcontroller with 128 KB flash, 10 KB RAM, and integrated LCD driver supporting up to 8 common and 32 segment outputs. It features a 20 MHz max CPU speed (50 ns min instruction), 10-bit × 10-channel ADC, dual 8-bit DACs, LIN hardware module, and operates from -40°C to +85°C in 64-pin LQFP. It targets embedded control in appliance user interfaces.

For engineers reviewing the R5F2L36CCDFP#31 datasheet, R5F2L36CCDFP#31 pinout, R5F2L36CCDFP#31 application, or R5F2L36CCDFP#31 equivalent, key selection criteria include LCD segment drive capability, D version temperature rating, 64-pin LQFP package compatibility, and integrated LIN bus support for appliance communication subsystems.

Technical Context

The R5F2L36CCDFP#31 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient signal processing. Its system clock generation includes XIN (20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - enabling flexible power mode selection including wait, stop, and power-off modes.

Peripheral integration centers on mixed-signal control: Timer RD provides 6-pin complementary PWM for motor drive, UART0/1/2 support LIN physical layer via UART0, and the LCD controller integrates VL1–VL4 bias pins and CL1/CL2 clock inputs for static/1/2/1/3/1/4/1/8 duty operation - all confirmed for the L36C group in Tables 1.1 and 1.5.
