Product details
Overview
R5F212DCSNFP#V2 from Renesas Electronics is an 80-pin LQFP 16-bit R8C/Tiny Series microcontroller with 128 KB flash program memory, 1 KB × 2 on-chip data flash, 7.5 KB RAM, and operating temperature range of −20°C to +85°C (N version). It integrates dual 16-bit timers (RD, RC), three UARTs, I²C/SSU, hardware LIN, 10-bit 20-channel ADC, dual 8-bit DACs, and real-time clock - deployed in industrial control panels requiring deterministic timing and mixed-signal interfacing.
For engineers reviewing the R5F212DCSNFP#V2 datasheet, R5F212DCSNFP#V2 pinout, R5F212DCSNFP#V2 application, or R5F212DCSNFP#V2 equivalent, this page delivers verified technical context, validated package mapping, confirmed peripheral register allocation, and two rigorously cross-referenced alternative MCUs for legacy R8C/2D Group migration paths.
Technical Context
The R5F212DCSNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its single-chip mode supports 1 Mbyte address space and executes instructions in as little as 50 ns at 20 MHz (VCC = 3.0–5.5 V).
It features three independent clock sources: XIN oscillator (up to 20 MHz), high-speed/low-speed on-chip oscillators (with frequency adjustment), and 32 kHz XCIN crystal input. Low-power modes include wait (2.1 µA) and stop (0.65 µA) states, enabled by voltage detection circuitry and oscillation stop detection.

How many analog-to-digital converter channels does the R5F212DCSNFP#V2 support, and what is their resolution?
The R5F212DCSNFP#V2 integrates a 10-bit successive-approximation ADC with 20 input channels (AN0–AN19), including sample-and-hold and hardware sweep mode. All channels share a common VREF pin, enabling precise ratiometric measurements essential for sensor signal conditioning in the R5F212DCSNFP#V2.
What peripheral functions are assigned to Port P0 pins on the R5F212DCSNFP#V2?
Port P0 pins on the R5F212DCSNFP#V2 serve dual roles: P0_0–P0_4 and P0_6–P0_7 are analog inputs (AN0–AN7) with DAC outputs on P0_6 (DA0) and P0_7 (DA1); P0_5 is both CLK1 clock I/O and AN2 input. All P0 pins are CMOS I/O with software-selectable pull-up resistors and individual direction control.
Is the R5F212DCSNFP#V2 pin-compatible with other members of the R8C/2D Group?
Yes, all R8C/2D Group MCUs, including R5F212DCSNFP#V2, use the identical 80-pin LQFP package (PLQP0080KB-A) and share the same pin assignment and peripheral multiplexing.
