Renesas R5F212L2SNFP#V2

Overview

R5F212L2SNFP#V2 from Renesas Electronics is an 8 KB flash, 1 KB RAM R8C/2L Group 16-bit microcontroller with on-chip 1 KB × 2 data flash, 10-bit 9-channel ADC, dual UART, hardware LIN, and four advanced PWM-capable timers (RA–RD) in a 32-pin LQFP package. It targets low-power embedded control in consumer appliances and office equipment operating from 2.2 V to 5.5 V.

For engineers reviewing the R5F212L2SNFP#V2 datasheet, R5F212L2SNFP#V2 pinout, R5F212L2SNFP#V2 application, or R5F212L2SNFP#V2 equivalent, key selection criteria include its -20°C to +85°C N-version temperature grade, 50 ns minimum instruction cycle at 20 MHz, integrated voltage detection (VDD = 3.0–5.5 V), and support for wait/stop low-power modes down to 0.7 µA.

Technical Context

The R5F212L2SNFP#V2 implements the R8C/Tiny Series CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and 16×16+32→32-bit MAC unit. Its memory architecture includes 8 KB program flash, 1 KB RAM, and two independent 1 KB data flash blocks enabling EEPROM-like parameter storage without external components.

Peripheral integration centers on timer RD - a dual 16-bit timer with 4 capture/compare registers supporting reset-synchronous three-phase PWM (6 pins), complementary PWM, and PWM3 mode - alongside timer RC (3-pin PWM), timers RA/RB (8-bit with waveform generation), hardware LIN over UART0, and 10-bit A/D conversion with sample-and-hold across nine analog inputs.

FAQ

What is the maximum operating frequency and corresponding supply voltage for R5F212L2SNFP#V2?

The R5F212L2SNFP#V2 supports a maximum operating frequency of 20 MHz at a supply voltage of 3.0 V to 5.5 V. At lower voltages, the maximum frequency is reduced: 10 MHz at 2.7–5.5 V and 5 MHz at 2.2–5.5 V (with A/D converter functional only above 2.7 V). These ratings are specified in the R8C/2L Group datasheet Rev.1.10.

Does R5F212L2SNFP#V2 include hardware support for LIN communication?

Yes, R5F212L2SNFP#V2 integrates a dedicated hardware LIN module compliant with LIN 2.0/2.1 standards. It uses UART0 and timer RA to implement the LIN physical layer and protocol timing, eliminating software-based bit-banging and ensuring deterministic frame transmission and reception.

How many analog input channels does R5F212L2SNFP#V2 provide, and what is their resolution?

R5F212L2SNFP#V2 provides nine analog input channels (AN2, AN4–AN11) with 10-bit resolution and integrated sample-and-hold functionality. This enables simultaneous sampling of multiple sensors - such as temperature, voltage, and current - with minimal external circuitry.

What low-power modes are available on R5F212L2SNFP#V2, and what are their typical current draws?

R5F212L2SNFP#V2 supports wait mode (23 µA at 3.0 V with low-speed on-chip oscillator) and stop mode (0.7 µA at 3.0 V). Both modes retain RAM contents and allow wake-up via external interrupt or timer event, making them ideal for battery-powered remote controls and sensor nodes.

Is R5F212L2SNFP#V2 pin-compatible with other members of the R8C/2L Group?

Yes, all R8C/2L Group MCUs in the PLQP0032GB-A (32-pin LQFP) package - including R5F212L2SNFP#V2, R5F212L4SNFP, R5F212L2SDFP, and R5F212L4SDFP - share identical pin assignments and electrical characteristics. Only memory size, data flash presence, and temperature grade differ between variants.
