The R5F212L4SNFP is a Renesas 16-bit single-chip microcontroller from the R8C/2L Group, built around the R8C/Tiny Series CPU core with a 1 Mbyte address space and an on-chip multiplier for fast processing. Running at up to 20 MHz from a wide 2.2 V to 5.5 V supply, it integrates 16 KB of flash program memory, 1.5 KB of RAM and 2 KB of on-chip data flash arranged as two 1 KB blocks, which is the defining difference between the R8C/2L and R8C/2K groups. Housed in a 32-LQFP (7 x 7 x 1.7 mm, 0.8 mm pitch) and rated -20°C to +85°C.
Key Features
● 16-bit R8C/Tiny CPU core with 1 Mbyte address space, efficient instruction set and an on-chip multiplier.
● 20 MHz maximum operating frequency with internal 20 MHz and 125 kHz on-chip oscillators, no PLL required.
● 16 KB flash program memory, 1.5 KB RAM and 2 KB data flash in two independently erasable 1 KB blocks.

FAQ
Q: Is it recommended for new designs? No, Renesas lists the R8C/2L Group as non-promotion and not recommended for new designs, recommending the RL78/G1F Group instead.
Q: What is the difference between R8C/2K and R8C/2L? Only the presence of on-chip data flash; the 2L group adds 1 KB x 2 blocks while all peripheral functions remain identical.
Q: Does it need an external crystal? No, internal 20 MHz and 125 kHz oscillators are provided, though an external resonator can still be used when tighter accuracy is needed.
