Product details
Overview
R5F212L4SNFP#X6 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2L Group, designed for embedded control in cost-sensitive consumer and industrial applications. It features 16 KB flash program ROM, 1.5 KB RAM, on-chip 1 KB × 2 data flash, 10-bit A/D converter with 9 channels, and integrated hardware LIN module supporting automotive body electronics and appliance motor control.
For engineers reviewing the R5F212L4SNFP#X6 datasheet, R5F212L4SNFP#X6 pinout, R5F212L4SNFP#X6 application, or R5F212L4SNFP#X6 equivalent, this page delivers verified specifications, validated pin functions, confirmed low-power operating modes (down to 0.7 µA stop mode), and real-world use context for rapid selection and integration into resource-constrained designs.
Technical Context
The R5F212L4SNFP#X6 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory architecture separates 16 KB program flash (1,000 erase cycles) from dual 1 KB data flash blocks (10,000 erase cycles), enabling robust firmware updates and parameter storage without external EEPROM.
Peripheral integration includes four independent timers (RA–RD), two UARTs with clock-synchronous serial I/O support, hardware LIN bus controller tied to Timer RA and UART0, and a 10-bit A/D converter with sample-and-hold-enabling closed-loop analog sensing and communication in single-chip motor drives and sensor nodes.

What is the maximum operating frequency and minimum supply voltage for R5F212L4SNFP#X6?
R5F212L4SNFP#X6 operates up to 20 MHz at VCC = 3.0–5.5 V, 10 MHz at VCC = 2.7–5.5 V, and 5 MHz at VCC = 2.2–5.5 V (with A/D functional only above 2.7 V). This graded frequency-voltage relationship enables flexible power/performance trade-offs in battery- and line-powered designs.
Does R5F212L4SNFP#X6 support hardware LIN communication?
Yes, R5F212L4SNFP#X6 integrates a dedicated hardware LIN module compliant with LIN 2.0/2.1 standards, implemented using UART0 and Timer RA. This eliminates software protocol overhead and guarantees timing accuracy for automotive body network slave nodes.
How many A/D input channels does R5F212L4SNFP#X6 have, and what is their resolution?
R5F212L4SNFP#X6 includes a 10-bit successive-approximation A/D converter with 9 input channels (AN2–AN11). Each channel supports sample-and-hold functionality, enabling accurate simultaneous sampling for multi-sensor applications like temperature and pressure monitoring.
What are the key differences between R5F212L4SNFP#X6 and R5F212K4SNFP?
R5F212L4SNFP#X6 includes dual 1 KB data flash blocks (10,000 erase cycles) for runtime parameter storage and firmware updates, while R5F212K4SNFP has only 16 KB program flash (1,000 erase cycles) and no data flash. Both share identical pinout, peripherals, and CPU core.
What low-power modes are available on R5F212L4SNFP#X6, and what are their typical current draws?
R5F212L4SNFP#X6 supports standard operating mode, wait mode (23 µA @ 3.0 V, low-speed oscillator active), and stop mode (0.7 µA @ 3.0 V, all clocks halted). These modes enable aggressive power budgeting in portable and energy-harvested systems without sacrificing responsiveness.
