Product details
Overview
R5F212DASDFP#V2 from Renesas Electronics is an 80-pin LQFP 16-bit R8C/Tiny Series microcontroller with 96 KB flash program memory, 1 KB × 2 on-chip data flash, 7 KB RAM, and operating temperature range of −40°C to +85°C (D version). It integrates dual 10-bit A/D converters (20 channels), dual 8-bit D/A converters, hardware LIN interface, and six independent timer modules including three-phase PWM-capable Timer RD - deployed in industrial motor control and appliance power management systems.
For engineers reviewing the R5F212DASDFP#V2 datasheet, R5F212DASDFP#V2 pinout, R5F212DASDFP#V2 application, or R5F212DASDFP#V2 equivalent, key selection considerations include its −40°C to +85°C industrial-grade qualification, 1 KB × 2 data flash endurance (10,000 erase/write cycles), real-time clock (Timer RE), and support for low-power stop mode (0.65 µA at 3.0 V).
Technical Context
The R5F212DASDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient embedded control execution. Its clock system includes XIN (up to 20 MHz), XCIN (32 kHz), and programmable high-speed/low-speed on-chip oscillators with frequency adjustment.
Peripheral integration centers on deterministic timing control: Timer RD provides reset-synchronous and complementary PWM for three-phase motor drive (6-pin output), while UART0–UART2, I2C/SSU shared interface, and hardware LIN (using Timer RA and UART0) support multi-protocol communication in resource-constrained systems.
