Product details
Overview
R5F2L358MNFP#31 from Renesas Electronics is a 16-bit R8C CPU core microcontroller in the R8C/L35M Group, featuring 64 KB program flash, 8 KB RAM, and 1 KB × 4 data flash with background operation (BGO). It delivers 50 ns minimum instruction execution at 20 MHz, integrates a 16×16→32-bit multiplier, and supports LCD drive (up to 4 COM / 24 SEG) for embedded control in household appliances.
For engineers reviewing the R5F2L358MNFP#31 datasheet, R5F2L358MNFP#31 pinout, R5F2L358MNFP#31 application, or R5F2L358MNFP#31 equivalent, key selection criteria include its 52-pin LQFP package, -20°C to +85°C operating range (N version), 41 programmable I/O ports with 5 high-current drive pins, and integrated peripherals including UART×3, I²C, LIN, 10-bit ADC (12 ch), and real-time clock timer RE.
Technical Context
The R5F2L358MNFP#31 implements the R8C CPU core with 89 fundamental instructions and single-chip mode addressing up to 1 Mbyte. Its clock system includes XIN (20 MHz max), XCIN (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all supporting wait/stop/power-off low-power modes.
Peripheral integration includes Timer RA–RG (8- to 16-bit), DTC with 38 activation sources, watchdog timer (14-bit with prescaler), voltage detection circuit (power-on reset + selectable VD levels), and dual 8-bit D/A converters. The LCD controller supports static, 1/2, 1/3, and 1/4 duty with 1/2 or 1/3 bias - but excludes VL3 and SEG52–SEG55, limiting bias and duty options versus higher-group variants.
