Product details
Overview
R5F2L357CNFP#30 from Renesas is a 16-bit R8C/L35C Group MCU with 48 KB flash, 6 KB RAM, and 1 KB × 4 data flash supporting background operation (BGO). It features a 41-pin programmable I/O interface, 10-channel 10-bit ADC, dual 8-bit DACs, LCD drive (max 4 COM / 24 SEG), and integrated LIN module using UART0 and Timer RA. It targets cost-sensitive, low-power embedded control in household appliance user interfaces.
For engineers reviewing the R5F2L357CNFP#30 datasheet, R5F2L357CNFP#30 pinout, R5F2L357CNFP#30 application, or R5F2L357CNFP#30 equivalent, key selection criteria include its 52-pin LQFP package, -20°C to +85°C N-version operating range, 20 MHz max CPU speed at 2.7–5.5 V, and dedicated LCD bias/duty support (1/2, 1/3 bias; static, 1/2, 1/3, 1/4 duty).
Technical Context
The R5F2L357CNFP#30 implements the R8C CPU core with 89 fundamental instructions and a hardware 16×16→32-bit multiplier for efficient signal processing. Its system clock generation includes XIN (20 MHz max), XCIN (32 kHz), high-speed on-chip oscillator (frequency-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 control: Timer RC (16-bit, 4 capture/compare registers) supports PWM output on 3 pins; Timer RD is absent in the L35C group; UART0/1/2 provide serial communication with I²C and LIN capability; and the DTC enables autonomous data transfers triggered by 38 sources including ADC completion and timer overflows.
