Product details
Overview
R5F212K4SYFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in 32-pin LQFP (PLQP0032GB-A), featuring 16 KB flash ROM, 1.5 KB RAM, 10-bit 9-channel ADC, hardware LIN interface, and four 8-/16-bit timers for motor control and embedded sensing in industrial appliances. It operates from 2.2 V to 5.5 V with -20°C to 105°C extended temperature range (Y version).
For engineers reviewing the R5F212K4SYFP#V2 datasheet, R5F212K4SYFP#V2 pinout, R5F212K4SYFP#V2 application, or R5F212K4SYFP#V2 equivalent, this page delivers verified specifications, validated pin functions, confirmed Y-version thermal rating, real-world use cases in appliance motor drives and sensor interfaces, and two technically documented alternative parts.
Technical Context
The R5F212K4SYFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and 7-level interrupt priority-enabling deterministic real-time response in closed-loop control. Its dual clock system integrates XIN oscillator (up to 20 MHz) and adjustable high-speed on-chip oscillator with stop-detection and selectable 1/2/4/8/16 frequency division.
Peripheral integration includes Timer RD supporting reset-synchronous and complementary PWM for three-phase motor drive (6-pin output), UART0+UART2 with LIN hardware acceleration, and 25 CMOS I/O ports with programmable pull-up and 8 high-current drive pins-optimized for direct LED and relay interfacing without external drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | R8C/Tiny 16-bit with 89 instructions, 50 ns min. instruction time at 20 MHz - enables fast loop execution in motor commutation and sensor sampling. |
| Memory | 16 KB flash ROM + 1.5 KB RAM - sufficient for standalone firmware with LIN protocol stack and PID control algorithms. |
| ADC | 10-bit resolution × 9 channels with sample-and-hold - supports simultaneous voltage/current sensing in power supply monitoring. |
| Timers | Timer RA/RB (8-bit), RC (16-bit, 4 compare/capture), RD (16-bit ×2, 6-PWM output) - provides full-bridge gate timing and three-phase waveform generation. |
| Operating Range | -20°C to +105°C ambient, 2.2–5.5 V supply - qualified for sealed industrial enclosures and high-temperature appliance environments. |
| Low-Power Modes | Wait mode (23 µA), stop mode (0.7 µA) - extends battery life in always-on sensor nodes and standby control logic. |
| LIN Interface | Hardware LIN v2.0 via UART0 + Timer RA - offloads protocol handling from CPU, reducing firmware overhead in automotive HVAC modules. |
Pinout & Package
Package: 32-pin LQFP (PLQP0032GB-A), 7 mm × 7 mm, 0.8 mm pitch, exposed pad not present. Compatible with standard reflow profiles for industrial PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC/AVCC (Pin 7) | Power supply input | Primary digital/analog supply rail; requires local 0.1 µF decoupling per VCC pin and bulk capacitor near AVCC for ADC stability. |
| VSS/AVSS (Pin 5) | Ground reference | Digital and analog ground return; must be connected to low-impedance ground plane to minimize ADC noise coupling. |
| XIN/P4_6 (Pin 6) | Clock input | Accepts 20 MHz crystal or external clock; internal feedback resistor enables single-crystal operation without external components. |
| RESET (Pin 3) | Active-low reset | Asynchronous reset input; internal POR circuit ensures reliable startup; external RC network optional for extended hold time. |
| P2_0/TRDIOA0/TRDCLK (Pin 16) | Timer RD I/O / clock input | Configurable as PWM output or external clock source for synchronized multi-phase timing in BLDC motor control. |
| AN8–AN11 (P1_0–P1_3, Pins 25–22) | Analog inputs | Four dedicated ADC channels with internal sample-and-hold; support differential measurement when paired with TRCIOA/TRCIOB. |
| TXD0/RXD0 (P1_4/P1_5, Pins 21/20) | UART0 data I/O | Full-duplex serial interface for LIN master/slave communication; TXD0 drives LIN bus via external transceiver (e.g., TJA1020). |
