It features 16 KB flash program memory, 1.5 KB RAM, on-chip 1 KB × 2 data flash, 10-bit A/D converter with 9 channels, and integrated hardware LIN interface using UART0 and Timer RA. It operates from 2.2 V to 5.5 V at up to 20 MHz (50 ns min instruction time) and supports -20°C to +85°C ambient temperature.

For engineers reviewing the R5F212L4SNFP#V2 datasheet, R5F212L4SNFP#V2 pinout, R5F212L4SNFP#V2 application, or R5F212L4SNFP#V2 equivalent, key selection considerations include its dual data flash blocks for reliable firmware/data updates, LIN bus support for automotive body electronics, low-power stop mode (0.7 µA), and 32-pin LQFP package with 25 CMOS I/Os and 8 high-current drive pins.

Technical Context

The R5F212L4SNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory architecture includes 16 KB flash ROM (1,000 write/erase cycles), two independent 1 KB data flash blocks (10,000 cycles), and 1.5 KB SRAM mapped within a 1 Mbyte address space.

Peripheral integration centers on four timer units: Timer RA/RB (8-bit), Timer RC (16-bit, 4 capture/compare), and Timer RD (16-bit ×2, 6-pin PWM, three-phase waveforms). It also integrates UART0/UART2, hardware LIN module, 10-bit ×9-channel A/D with sample-and-hold, voltage detection circuit, and multiple low-power modes including wait (23 µA) and stop (0.7 µA).

FAQ

What is the maximum operating frequency and corresponding supply voltage range for R5F212L4SNFP#V2?

R5F212L4SNFP#V2 supports up to 20 MHz operation at VCC = 3.0–5.5 V, 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). Minimum instruction execution time is 50 ns under 20 MHz/5.0 V conditions, confirmed in Renesas documentation REJ03B0219-0110.

Does R5F212L4SNFP#V2 include hardware support for LIN communication?

Yes, R5F212L4SNFP#V2 integrates a dedicated hardware LIN module using UART0 and Timer RA, enabling compliant LIN 2.2 slave node operation without CPU overhead. This implementation supports standard baud rates (1.2–20 kbps), sync field detection, and checksum validation per LIN specification.

How many A/D converter channels does R5F212L4SNFP#V2 provide, and what is their resolution?

R5F212L4SNFP#V2 includes a 10-bit successive-approximation A/D converter with 9 input channels (AN2, AN4–AN11). It features sample-and-hold functionality and operates across the full 2.2–5.5 V supply range, with conversion time of 16 µs typical at 10 MHz CPU clock.

What are the data flash endurance specifications for R5F212L4SNFP#V2?

R5F212L4SNFP#V2 provides two independent 1 KB data flash blocks rated for 10,000 write/erase cycles each. This is distinct from the 16 KB program flash (1,000 cycles) and enables reliable storage of calibration data, configuration parameters, or firmware update staging areas.

Is R5F212L4SNFP#V2 pin-compatible with other members of the R8C/2L Group?

Yes, all R8C/2L Group MCUs including R5F212L4SNFP#V2 use the identical 32-pin LQFP (PLQP0032GB-A) package and share the same pin assignment and electrical characteristics. Memory size and temperature grade vary by suffix (e.g., 'N' vs 'D'), but pin functions and layout remain fully compatible.
