Product details

Overview

R5F212BCSNFP#X6 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2B Group, featuring 128 KB flash program memory, 2 KB on-chip data flash (1 KB × 2 blocks), 7.5 KB RAM, and operation up to 20 MHz at 3.0–5.5 V. It integrates dual UARTs, LIN hardware support, 12-channel 10-bit ADC, dual 8-bit DACs, and six advanced timers including complementary PWM for motor control - deployed in industrial appliance control systems.

For engineers reviewing the R5F212BCSNFP#X6 datasheet, R5F212BCSNFP#X6 pinout, R5F212BCSNFP#X6 application, or R5F212BCSNFP#X6 equivalent, key selection criteria include its N-version temperature range (−20°C to +85°C), 64-pin LQFP package (PLQP0064KB-A), on-chip debug capability, and data flash endurance of 10,000 erase/write cycles - critical for firmware-over-the-air updates and parameter storage in field-deployed devices.

Technical Context

This MCU implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability. Its clock system includes XIN oscillator (up to 20 MHz), high-speed/low-speed on-chip oscillators, and 32 kHz XCIN real-time clock input - enabling flexible low-power mode sequencing (wait mode: 2.1 µA, stop mode: 0.65 µA).

Peripheral integration centers on deterministic timing control: Timer RD supports reset-synchronous and complementary PWM for three-phase motor drives; Timer RC and RF provide input capture and output compare for encoder interfacing; UART0 is hardwired to LIN physical layer via timer RA, enabling automotive body electronics communication without external transceivers.
