Product details
Overview
R5F212DASNFP#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 a 20 MHz-capable R8C CPU core with 16×16→32-bit multiplier, 10-bit ×20-channel ADC, dual 8-bit DACs, six timer modules (including three-phase PWM-capable Timer RD), hardware LIN interface, and UART/SSU/I²C serial interfaces. It targets embedded control in industrial motor drives and appliance power management systems.
For engineers reviewing the R5F212DASNFP#V2 datasheet, R5F212DASNFP#V2 pinout, R5F212DASNFP#V2 application, or R5F212DASNFP#V2 equivalent, key selection criteria include its −40°C to +85°C industrial-grade temperature rating, dual on-chip 1 KB data flash blocks for EEPROM-like parameter storage, 71 CMOS I/O pins with selectable pull-up resistors, and integrated hardware LIN transceiver support via UART0 and Timer RA.
Technical Context
The R5F212DASNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-cycle multiply-accumulate capability (16×16+32→32 bits). Its clock system includes three independent oscillation circuits: XIN (up to 20 MHz crystal/resonator), XCIN (32 kHz crystal), and high-/low-speed on-chip oscillators-with frequency adjustment for the high-speed variant.
Peripheral integration centers on deterministic real-time control: Timer RD provides reset-synchronous and complementary PWM outputs for three-phase motor drive (6-pin output), while Timer RC and RF support input capture and output compare for precise timing. The LIN module combines UART0 and Timer RA for ISO 9141-2/SAE J2602-compliant communication without external transceiver.
