FAQ

What is the maximum operating frequency of the R5F212G6SNFP?

The R5F212G6SNFP supports a maximum system clock of 8 MHz when operated at 2.7–5.5 V supply voltage. At this frequency, the minimum instruction execution time is 125 ns. The device also supports 4 MHz operation down to 2.2 V, enabling flexible power/performance trade-offs in battery-powered designs. The R5F212G6SNFP uses an on-chip high-speed oscillator with frequency adjustment capability, eliminating need for external crystals in many applications.

Does the R5F212G6SNFP include hardware LIN bus support?

Yes, the R5F212G6SNFP integrates a dedicated hardware LIN module compliant with LIN 2.0/2.1 specifications. It leverages UART0 and timer RA to implement the LIN physical and data link layers - reducing CPU load during frame transmission and reception. This allows the R5F212G6SNFP to serve as a LIN slave node in automotive body electronics or industrial sensor networks without external transceivers beyond the standard LIN bus driver.

What package type and pin count does the R5F212G6SNFP use?

The R5F212G6SNFP is housed in a 32-pin LQFP package designated PLQP0032GB-A (formerly 32P6U-A), measuring 7 mm × 7 mm with 0.8 mm lead pitch. This RoHS-compliant package features 27 general-purpose CMOS I/O pins, power/ground, reset, oscillator, and dedicated peripheral signal pins - fully documented in the R8C/2G Group datasheet Figure 1.3 and Table 1.3.

How much Flash memory and RAM does the R5F212G6SNFP provide?

The R5F212G6SNFP contains 32 KB of on-chip Flash memory (rated for 100 program/erase cycles) and 1 KB of SRAM. The Flash supports in-system programming via on-chip debug interface, while the RAM provides data storage for variables, stacks, and buffers. This memory configuration is validated in Table 1.2 of the R8C/2G Group datasheet REJ03B0223-0100 and matches the "6" ROM capacity code in the part number.

What is the operating temperature range for the R5F212G6SNFP?

The R5F212G6SNFP is an N-version device rated for operation from −20°C to +85°C ambient temperature. This classification is indicated by the "N" in the suffix "SNFP" and aligns with Renesas' "Standard" quality grade per Notice #7 in the datasheet - intended for computers, office equipment, consumer electronics, and industrial robots. For extended temperature requirements, the D-version R5F212G6SDFP (−40°C to +85°C) is available.
