Product details
Overview
R5F2L36CCNFP#31 from Renesas Electronics is a 16-bit R8C/L36C Group microcontroller featuring the R8C CPU core, 128 KB flash program memory, 10 KB data flash (4 × 1 KB blocks with background operation), and 10 KB RAM. It delivers 50 ns minimum instruction execution at 20 MHz, integrates a 16×16→32-bit hardware multiplier, and supports LCD drive (up to 8 COM / 32 SEG) for embedded appliance control interfaces.
For engineers reviewing the R5F2L36CCNFP#31 datasheet, R5F2L36CCNFP#31 pinout, R5F2L36CCNFP#31 application, or R5F2L36CCNFP#31 equivalent, key selection criteria include its 64-pin LQFP package, 52 programmable I/O ports (including 8 high-current drive pins), 10-bit × 10-channel ADC with sample-and-hold, dual 8-bit D/A converters, and integrated LIN physical layer support via UART0 and Timer RA.
Technical Context
The R5F2L36CCNFP#31 implements the R8C CPU core with 89 fundamental instructions and a 1 Mbyte address space, enabling efficient C-language execution in resource-constrained systems. Its clock system includes four independent sources: XIN oscillator (up to 20 MHz), 32 kHz XCIN crystal circuit, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via software-controlled frequency dividers (1/2/4/8/16).
Peripheral integration centers on mixed-signal timing and interface functions: Timer RD provides 16-bit dual-channel PWM with complementary three-phase output (6-pin), Timer RC offers 3-pin PWM and input capture, while UART0–UART2 plus I²C/SSU and hardware LIN enable robust serial communication. The DTC (Data Transfer Controller) supports 38 activation sources and repeat-mode transfers to offload CPU bandwidth during ADC or serial data handling.

Yes, the R5F2L36CCNFP#31 integrates Timer RE as a dedicated real-time clock module. It supports calendar mode (seconds, minutes, hours, days of week) when driven by the 32 kHz XCIN crystal oscillator, eliminating the need for an external RTC IC in time-aware applications like thermostats or appliance scheduling.
How many analog-to-digital converter (ADC) channels does the R5F2L36CCNFP#31 support, and what is their resolution?
The R5F2L36CCNFP#31 includes a 10-bit successive-approximation ADC with 10 input channels (AN0–AN9). It features sample-and-hold capability and sweep mode for automatic channel sequencing - sufficient for simultaneous monitoring of temperature sensors, potentiometers, and power supply rails in appliance control systems.
Can the R5F2L36CCNFP#31 drive a character LCD directly, and what are the supported bias and duty configurations?
Yes, the R5F2L36CCNFP#31's integrated LCD controller supports direct drive of character or segment-based LCDs with up to 8 common (COM) and 32 segment (SEG) outputs. Bias options include 1/2, 1/3, and 1/4; duty cycle options are static, 1/2, 1/3, 1/4, and 1/8 - compatible with standard 4×32 character displays used in consumer appliance UIs.
