Product details
Overview
R5F2L368MNFP#31 from Renesas is a 16-bit R8C CPU core MCU with 64 KB flash, 8 KB RAM, and integrated LCD controller supporting up to 8 common/32 segment outputs. It features 52 programmable I/O pins (including 8 high-current drive), 12-channel 10-bit ADC, dual 8-bit DACs, UART/I²C/SSU serial interfaces, LIN module, and real-time clock (Timer RE). Designed for cost-sensitive consumer appliance control with low-power operation down to 2 µA in stop mode.
For engineers reviewing the R5F2L368MNFP#31 datasheet, R5F2L368MNFP#31 pinout, R5F2L368MNFP#31 application, or R5F2L368MNFP#31 equivalent, this page delivers verified technical context, package mapping, functional alternatives, and design-specific guidance for household appliance, audio equipment, and office device implementations requiring integrated LCD drive and mixed-signal control.
Technical Context
The R5F2L368MNFP#31 implements the R8C CPU core with 89 fundamental instructions and hardware multiplier (16×16→32 bits), enabling efficient signal processing and control loop execution. Its memory architecture includes 64 KB program flash with background operation (BGO) and 1 KB × 4 data flash blocks for parameter storage without halting code execution.
Peripheral integration centers on mixed-signal timing and display: Timer RD provides 6-pin PWM with complementary three-phase output for motor control; Timer RG supports phase-counting and single-pin PWM; the LCD controller integrates VL1–VL4 bias generation and CL1/CL2 clock inputs for static/1/2/1/3/1/4 duty operation with up to 32 segment drivers.
