For engineers reviewing the R5F212L2SNFP#X6 datasheet, R5F212L2SNFP#X6 pinout, R5F212L2SNFP#X6 application, or R5F212L2SNFP#X6 equivalent, key selection criteria include its on-chip data flash (1 KB × 2 blocks), -20°C to +85°C N-version temperature grade, low-power stop mode (0.7 µA), and integrated LIN physical layer support for automotive body electronics.

Technical Context

The R5F212L2SNFP#X6 implements the R8C/Tiny Series CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and 1 Mbyte address space. It executes instructions in as little as 50 ns at 20 MHz (VCC = 3.0–5.5 V) and supports single-chip operation without external memory.

Its peripheral set includes UART0/UART2, Timer RA/RB (8-bit), Timer RC (16-bit, 4 capture/compare registers), Timer RD (16-bit × 2, 4 capture/compare registers, complementary PWM, reset-synchronous PWM), and a hardware LIN module tied to UART0 and Timer RA - enabling direct LIN bus communication without software bit-banging.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212L2SNFP#X6?

The R5F212L2SNFP#X6 operates at up to 20 MHz when supplied with 3.0–5.5 V, supports 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). Its R8C/Tiny CPU core achieves a minimum instruction execution time of 50 ns under the 20 MHz/5.0 V condition, confirmed in Renesas REJ03B0219-0110 Rev.1.10.

Does the R5F212L2SNFP#X6 include on-chip data flash, and what is its endurance?

Yes, the R5F212L2SNFP#X6 includes 1 KB × 2 blocks of on-chip data flash, rated for 10,000 program/erase cycles - distinct from its 8 KB program flash (1,000 cycles). This enables reliable storage of calibration coefficients, device IDs, or runtime configuration data without external memory, as specified in Table 1.4 of the R8C/2L Group datasheet.

How does the hardware LIN module function in the R5F212L2SNFP#X6?

The R5F212L2SNFP#X6 implements a hardware LIN 2.0/2.1 module using UART0 for serial framing and Timer RA for baud rate timing and sync field detection. This offloads LIN protocol handling from the CPU, supporting automatic checksum calculation, identifier filtering, and error recovery - verified in Section 1.1.2 and Figure 1.3 of the official Renesas documentation.

What are the low-power modes supported by the R5F212L2SNFP#X6, and their typical current consumption?

The R5F212L2SNFP#X6 supports wait mode (23 µA @ 3.0 V, low-speed on-chip oscillator) and stop mode (0.7 µA @ 3.0 V), in addition to standard active operation (10 mA @ 5.0 V/20 MHz). These modes are controlled via system control registers and validated in Table 1.4 of the R8C/2L Group datasheet, enabling energy-efficient operation in battery-powered applications.

Is the R5F212L2SNFP#X6 pin-compatible with other members of the R8C/2L Group?

Yes, all R8C/2L Group MCUs, including R5F212L2SNFP#X6, R5F212L4SNFP, and R5F212L2SDFP, share the identical 32-pin LQFP package (PLQP0032GB-A) and pin assignment per Figure 1.4 and Table 1.7. Differences are limited to memory size, temperature grade (N/D/Y), and factory programming - allowing PCB reuse across variants.
