Product details
Overview
R5F212L2SYFP#V2 from Renesas Electronics is an 8 KB flash, 1 KB × 2 data flash, 1 KB RAM R8C/2L Group 16-bit MCU with R8C/Tiny CPU core, operating at up to 20 MHz (VCC = 3.0–5.5 V), featuring 10-bit × 9-channel A/D converter, hardware LIN module, and 32-pin LQFP package for embedded control in consumer and industrial appliances.
For engineers reviewing the R5F212L2SYFP#V2 datasheet, R5F212L2SYFP#V2 pinout, R5F212L2SYFP#V2 application, or R5F212L2SYFP#V2 equivalent, this page delivers verified specifications, temperature-grade validation (−20°C to 105°C), on-chip debug support, and real-world timing/peripheral interoperability for rapid integration into cost-sensitive, low-power control systems.
Technical Context
The R5F212L2SYFP#V2 implements the R8C/Tiny Series CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability-enabling deterministic real-time control loops. Its memory architecture separates 8 KB program flash from dual 1 KB data flash blocks, supporting field firmware updates without erasing application code.
Peripheral integration includes Timer RD (16-bit × 2, 6-pin PWM + three-phase waveform generation), UART0/UART2, hardware LIN bus controller (using Timer RA and UART0), and 9-channel sample-and-hold A/D converter-all mapped to a fixed 32-pin LQFP (PLQP0032GB-A) with dedicated analog supply pins (AVCC/AVSS) and reference input (VREF).

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC/AVCC | Power supply / Analog reference rail | Dual-purpose pin: powers digital logic and A/D converter; requires separate decoupling from VSS/AVSS |
| VSS/AVSS | Ground / Analog ground | Common return for digital and analog sections; layout separation critical for A/D accuracy |
| XIN/XOUT | External crystal/resonator interface | Supports 20 MHz max crystal; XOUT is output-only; external clock may be applied to XIN only |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F212L2SNFP | Same core, flash, and peripherals but N-grade (−20°C to +85°C); lacks Y-version extended temperature qualification | Suitable for indoor consumer devices without thermal stress; not qualified for sealed or sun-exposed enclosures | Select R5F212L2SNFP only when ambient operating temperature remains ≤85°C and cost sensitivity outweighs thermal margin needs. |
| R5F212L4SDFP | D-grade (−40°C to +85°C) with 16 KB program flash and 1.5 KB RAM; retains same data flash and peripheral set | Targeted at industrial control requiring cold-start capability but not high-temperature operation; larger code space for complex protocols | Choose R5F212L4SDFP when firmware exceeds 8 KB and application must operate below 0°C-without needing +105°C capability. |
Compared with R5F212L2SNFP, the R5F212L2SYFP#V2 adds guaranteed operation up to +105°C and eliminates thermal derating concerns in enclosed spaces; versus R5F212L4SDFP, it trades flash size and cold tolerance for higher-temperature resilience and lower memory footprint-making it optimal for thermally demanding, cost-constrained appliance nodes.

FAQ
What is the maximum operating frequency of the R5F212L2SYFP#V2 and under what supply conditions?
The R5F212L2SYFP#V2 operates at up to 20 MHz when supplied with VCC = 3.0 V to 5.5 V. At lower voltages (2.7–5.5 V), maximum frequency drops to 10 MHz; at 2.2–5.5 V, it is limited to 5 MHz. The A/D converter requires VCC ≥ 2.7 V regardless of CPU clock speed. These ratings are validated across the full −20°C to +105°C operating range of the R5F212L2SYFP#V2.
Does the R5F212L2SYFP#V2 support in-circuit debugging and flash reprogramming?
Yes, the R5F212L2SYFP#V2 includes on-chip debug functionality and on-board flash rewrite capability. It supports programming and erasure of both program ROM (1,000 cycles) and data flash (10,000 cycles) at standard VCC levels (2.7–5.5 V), enabling field firmware updates and parameter tuning without removing the R5F212L2SYFP#V2 from the target board.
How many A/D converter channels does the R5F212L2SYFP#V2 have, and what is their resolution?
The R5F212L2SYFP#V2 integrates a 10-bit successive-approximation A/D converter with 9 input channels (AN2, AN4–AN11). Each channel includes a sample-and-hold circuit, allowing accurate conversion of fast-changing analog signals such as motor phase currents or thermistor outputs-critical for closed-loop control in applications using the R5F212L2SYFP#V2.
What peripheral functions are enabled by the Timer RD module in the R5F212L2SYFP#V2?
Timer RD in the R5F212L2SYFP#V2 provides two independent 16-bit timers with four capture/compare registers each. It supports input capture, output compare, 6-pin PWM, reset-synchronous PWM (for three-phase inverters), complementary PWM (with triangular modulation), and PWM3 mode-making it the primary timing resource for motor control, power conversion, and precision waveform generation in designs based on the R5F212L2SYFP#V2.
Is the R5F212L2SYFP#V2 pin-compatible with other members of the R8C/2L Group?
Yes, all R8C/2L Group MCUs-including R5F212L2SYFP#V2-share identical 32-pin LQFP (PLQP0032GB-A) packaging and pin assignments. Function mapping (e.g., UART, A/D, timer I/O) is consistent across variants; only memory size, temperature grade, and data flash configuration differ. This allows hardware reuse when migrating between R5F212L2SYFP#V2 and other R8C/2L parts like R5F212L4SDFP.
