FAQ

What is the maximum operating frequency and supply voltage range for R5F212A8SNFP#V2?

R5F212A8SNFP#V2 operates at up to 20 MHz when supplied at 3.0–5.5 V, 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V. These graded frequency/voltage ratings ensure reliable timing margins across varying input conditions and enable dynamic voltage scaling in power-aware designs. The R5F212A8SNFP#V2 datasheet specifies minimum instruction execution times of 50 ns, 100 ns, and 200 ns respectively.

Does R5F212A8SNFP#V2 include on-chip data flash memory?

No, R5F212A8SNFP#V2 belongs to the R8C/2A Group and contains only program flash ROM (64 KB) with 1,000 erase/write cycles. It does not integrate data flash. For on-chip data storage, consider R8C/2B Group members like R5F212B8SNFP#V2, which adds 1 KB × 2 blocks of data flash rated for 10,000 cycles. The R5F212A8SNFP#V2 requires external EEPROM or FRAM if nonvolatile parameter storage is needed.

Which package type does R5F212A8SNFP#V2 use, and what are its dimensions?

R5F212A8SNFP#V2 uses the PLQP0064KB-A 64-pin LQFP package: 10 mm × 10 mm body size, 0.5 mm pin pitch, and 1.6 mm max height. This compact footprint supports high-density PCB layouts typical in consumer audio and appliance control boards. The R5F212A8SNFP#V2 pinout matches Figure 1.4 in the Renesas R8C/2A Group datasheet, with defined thermal pad grounding and moisture sensitivity level (MSL) 3 handling requirements.

Can R5F212A8SNFP#V2 be used for LIN bus communication?

Yes, R5F212A8SNFP#V2 includes a hardware LIN module implemented using UART0 and Timer RA, supporting LIN 2.0 and 2.1 protocols. It handles break field generation, sync byte detection, and checksum calculation in hardware-reducing CPU load and ensuring timing compliance. The R5F212A8SNFP#V2 requires an external LIN transceiver (e.g., TJA1020) for physical layer interfacing, as the MCU itself does not integrate bus driver circuitry.

What low-power modes are supported by R5F212A8SNFP#V2, and how deep is stop mode?

R5F212A8SNFP#V2 supports wait mode (2.1 µA at 3.0 V with 32 kHz RTC clock active) and stop mode (0.65 µA at 3.0 V with all clocks halted except optional 32 kHz sub-clock). Stop mode retains RAM contents and allows wake-up via RESET, external interrupts (INT0–INT3), or RTC alarm. This ultra-low quiescent current makes the R5F212A8SNFP#V2 suitable for battery-backed applications where multi-year operation is required between charges or replacements.
