Renesas R5F212D8SNFP#V2

Overview

R5F212D8SNFP#V2 from Renesas Electronics is an 80-pin LQFP 16-bit R8C/Tiny Series MCU with 64 KB flash program memory, 1 KB × 2 on-chip data flash, 3 KB RAM, and operation over −20°C to +85°C. It integrates dual 10-bit A/D converters (20 channels), dual 8-bit D/A converters, hardware LIN interface, and six timer modules including three-phase PWM-capable Timer RD - used in motor control subsystems of home appliance mainboards.

For engineers reviewing the R5F212D8SNFP#V2 datasheet, R5F212D8SNFP#V2 pinout, R5F212D8SNFP#V2 application, or R5F212D8SNFP#V2 equivalent, key selection criteria include its −20°C to +85°C industrial temperature grade, 1 KB × 2 data flash endurance (10,000 erase/write cycles), integrated LIN physical layer support via UART0+Timer RA, real-time clock capability (Timer RE), and low-power stop mode current of 0.65 µA at 3.0 V.

Technical Context

The R5F212D8SNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier for efficient motor control math. Its clock system includes XIN (up to 20 MHz), XCIN (32 kHz real-time clock source), and adjustable high-speed on-chip oscillator.

Peripheral integration centers on deterministic timing: Timer RD provides reset-synchronous three-phase PWM (6-pin output) with sawtooth/triangular modulation, while Timer RC supports 3-pin PWM and Timer RB enables programmable waveform generation - all synchronized to a common prescaler and clock divider (1/2/4/8/16).

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212D8SNFP#V2?

The R5F212D8SNFP#V2 supports up to 20 MHz operation at VCC = 3.0–5.5 V, 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V. Its minimum supply voltage is 2.2 V, enabling compatibility with single-cell Li-ion or multi-cell alkaline systems where brownout resilience is critical. The R5F212D8SNFP#V2 includes built-in voltage detection circuits for power-on reset and level monitoring.

Does the R5F212D8SNFP#V2 support hardware LIN communication, and how is it implemented?

Yes, the R5F212D8SNFP#V2 integrates a hardware LIN interface using UART0 combined with Timer RA for baud rate generation and synchronization. This eliminates external transceivers in slave-node applications like automotive door modules or appliance sub-controllers. The R5F212D8SNFP#V2 conforms to LIN 2.1/2.2 specifications and supports auto-baud detection and checksum calculation in firmware.

How many A/D and D/A channels does the R5F212D8SNFP#V2 provide, and what are their resolutions?

The R5F212D8SNFP#V2 features a 10-bit A/D converter with 20 input channels (AN0–AN19), including sample-and-hold and automatic sweep mode for sequential conversion. It also includes two independent 8-bit D/A converters (DA0 and DA1) with dedicated output pins (P0_6 and P0_7). These analog resources are fully integrated and require no external precision references beyond VREF.

What low-power modes are available on the R5F212D8SNFP#V2, and what is the lowest current consumption?

The R5F212D8SNFP#V2 offers wait mode (2.1 µA @ 3.0 V, f(XCIN) = 32 kHz) and stop mode (0.65 µA @ 3.0 V), both retaining RAM contents and selected wake-up sources. Stop mode disables the CPU, flash, and most peripherals while preserving Timer RE (real-time clock) operation. The R5F212D8SNFP#V2 achieves this ultra-low current via gated clock domains and leakage-optimized I/O retention.

Is the R5F212D8SNFP#V2 pin-compatible with other members of the R8C/2D Group?

Yes, all R8C/2D Group MCUs - including R5F212D7SNFP, R5F212D8SNFP#V2, R5F212DASNFP, and R5F212DCSNFP - share identical 80-pin LQFP (PLQP0080KB-A) packaging and full pin-to-pin compatibility. Differences are limited to flash size (48–128 KB), data flash (1 KB × 2), RAM (2.5–7.5 KB), and temperature grade - enabling scalable design reuse across product tiers using the R5F212D8SNFP#V2 footprint.
