It integrates an 8-channel 16-bit timer, 7-channel 8/10-bit ADC, dual comparators, UART, two simplified SPI (CSI) channels, two simplified I²C channels, and on-chip debug - targeting industrial motor control, sensor nodes, and power management systems.

For engineers reviewing the R5F12047MNA#60 datasheet, R5F12047MNA#60 pinout, R5F12047MNA#60 application, or R5F12047MNA#60 equivalent, key selection criteria include its M-grade temperature rating (+125°C), 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, 4 KB flash capacity, dual comparator support, and hardware-based BCD correction for metering applications.

Technical Context

The R5F12047MNA#60 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution at 0.0625 μs (16 MHz high-speed on-chip oscillator). Its clock system supports selectable high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy at −20°C to +85°C), low-speed on-chip oscillator (15 kHz), and external crystal (X1/X2, up to 12 MHz).

It features a unified peripheral I/O redirection register (PIOR) enabling flexible pin function assignment, including multiplexed timer outputs (TI00–TI07/TO00–TO07), serial interfaces (CSI00/CSI01, IIC00/IIC01, UART0), and analog inputs (ANI0–ANI6) with internal reference (0.815 V TYP.) and comparator outputs (VCOUT0/VCOUT1).

FAQ

What is the maximum operating frequency of the R5F12047MNA#60?

The R5F12047MNA#60 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, delivering a minimum instruction execution time of 0.0625 μs. External crystal operation is rated up to 12 MHz. The actual achievable frequency depends on VDD (2.4–5.5 V) and ambient temperature (−40°C to +125°C), with oscillator accuracy specified as ±1.0% at −20°C to +85°C for M-grade units.

Does the R5F12047MNA#60 support in-system programming?

Yes, the R5F12047MNA#60 supports in-system programming via its on-chip debug interface and self-programming flash controller. Code and data flash can be rewritten without boot swap functionality, enabling field firmware updates. However, background operation (BGO) is not supported - code execution halts during data flash writes, requiring careful state management in real-time applications.

How many analog input channels does the R5F12047MNA#60 provide?

The R5F12047MNA#60 provides 7 analog input channels (ANI0 through ANI6), compatible with its 8/10-bit resolution A/D converter. These channels operate across the full VDD range (2.4–5.5 V) and support internal reference voltage (0.815 V TYP.) or external reference inputs (IVREF0/IVREF1), making it suitable for precision sensor interfacing in industrial environments.

What package type and dimensions does the R5F12047MNA#60 use?

The R5F12047MNA#60 uses a 16-pin HWQFN package measuring 3 mm × 3 mm with 0.5-mm pitch and an exposed thermal pad. Per datasheet Remark 3, this pad must be soldered to a non-electrical PCB thermal plane to ensure proper thermal dissipation and electrical stability in high-temperature industrial operation.

Can the R5F12047MNA#60 operate reliably at +125°C ambient temperature?

Yes, the R5F12047MNA#60 is qualified for continuous operation from −40°C to +125°C (M-grade industrial specification). Its electrical characteristics - including flash endurance, oscillator accuracy (±1.5% at +85°C to +125°C), and DC parameters - are guaranteed across this full range, making it suitable for under-hood automotive, industrial motor drives, and power conversion systems.
