FAQ
What is the maximum operating frequency of the R5F12047MSP#10's high-speed on-chip oscillator?
The R5F12047MSP#10 supports a high-speed on-chip oscillator frequency of up to 16 MHz, with ±1.0% accuracy over −20°C to +85°C and ±1.5% over −40°C to −20°C or +85°C to +125°C. This enables a minimum instruction execution time of 0.0625 μs at full speed, making the R5F12047MSP#10 suitable for real-time control loops in motor drive applications.
How many analog input channels does the R5F12047MSP#10 support, and what resolution options are available?
The R5F12047MSP#10 integrates an 8/10-bit resolution A/D converter with 7 analog input channels (ANI0–ANI6). Resolution is software-selectable per conversion, and the internal 0.815 V reference voltage enables accurate ratiometric measurements without external references. This capability is confirmed in the RL78/G15 datasheet section 1.1 and Table 1-4 for 16-pin products.
Does the R5F12047MSP#10 support in-system programming, and what interface is used?
Yes, the R5F12047MSP#10 supports in-system programming via its on-chip debug interface using the TOOLRxD and TOOLTxD pins (P01 and P00), which implement a UART-based protocol. The device also supports self-programming of both code and data flash memory without requiring a boot swap function, enabling field firmware updates directly through the application firmware.
What is the purpose of the PCLBUZ0 pin on the R5F12047MSP#10, and how is it configured?
The PCLBUZ0 pin (P02) on the R5F12047MSP#10 serves as a programmable clock/buzzer output, capable of generating square-wave tones up to 10 MHz for audible alerts or clocking external logic. It is configured via the peripheral I/O redirection register (PIOR) and operates independently of CPU load - allowing precise timing without software overhead. This function is documented in the RL78/G15 User's Manual section 6.10.
Can the R5F12047MSP#10 operate reliably at +125°C, and what grade designation confirms this?
Yes, the R5F12047MSP#10 is qualified for continuous operation from −40°C to +125°C, as indicated by the "M" suffix in its part number per Figure 1-1 of the datasheet. This M-grade industrial qualification is verified under electrical specifications for TA = −40°C to +125°C, including oscillator accuracy, flash endurance, and DC characteristics - making it suitable for under-hood automotive or enclosed industrial environments.
