Overview
R5F12047ANA#40 from Renesas Electronics is a 16-pin HWQFN-packaged RL78/G15 16-bit microcontroller with 4 KB code flash, 1 KB data flash, and 1 KB RAM. It operates from 2.4 V to 5.5 V, supports 16 MHz high-speed on-chip oscillator (±1.0% accuracy at −20°C to +85°C), and delivers true low-power operation for industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F12047ANA#40 datasheet, R5F12047ANA#40 pinout, R5F12047ANA#40 application, or R5F12047ANA#40 equivalent, key selection criteria include its 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, 7-channel 8/10-bit ADC, dual simplified I²C interfaces, and support for STOP/HALT low-power modes in consumer-grade temperature range (−40°C to +85°C).
Technical Context
The R5F12047ANA#40 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It integrates a 12-bit interval timer, watchdog timer, and TAU0 16-bit timer array with 8 channels - configurable for PWM output across up to 6 pins.
Its analog subsystem includes a 7-channel 8/10-bit A/D converter with internal 0.815 V reference, two comparators (one with selectable external/internal reference), and programmable clock/buzzer output (PCLBUZ0). Serial connectivity comprises one UART, two simplified SPI (CSI) channels, two simplified I²C channels, and one full I²C bus interface.

FAQ
What is the maximum operating frequency of the R5F12047ANA#40?
The R5F12047ANA#40 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, delivering a minimum instruction execution time of 0.0625 μs. This frequency is selectable via option byte bits 0–2 and maintains ±1.0% accuracy across −20°C to +85°C ambient conditions. External crystal oscillation up to 12 MHz is also supported via X1/X2 pins.
Does the R5F12047ANA#40 support in-system programming?
Yes, the R5F12047ANA#40 supports self-programming of both code flash and data flash memory without requiring a boot swap function. The on-chip debug interface enables firmware updates via TOOL0/TOOLRxD/TOOLTxD pins, and background operation is not supported during data flash writes - instructions must be executed from RAM or other memory during rewrites.
How many analog input channels does the R5F12047ANA#40 provide?
The R5F12047ANA#40 provides 7 analog input channels (ANI0 to ANI6), compatible with its 8/10-bit resolution A/D converter. These channels operate across the full VDD range (2.4 V to 5.5 V) and support internal reference voltage (0.815 V TYP.) or external reference inputs (IVREF0/IVREF1), enabling flexible sensor interfacing without external voltage references.
What low-power modes are available on the R5F12047ANA#40?
The R5F12047ANA#40 offers HALT and STOP low-power modes. In HALT mode, the CPU stops but peripherals remain active; in STOP mode, both CPU and most peripherals halt while retaining RAM and register contents. Both modes support wake-up via external interrupt (INTP0–INTP7), timer events, or comparator output transitions - critical for battery longevity in intermittent-sensing applications.
Is the R5F12047ANA#40 pin-compatible with other RL78/G15 variants?
Yes, the R5F12047ANA#40 is pin-compatible with all 16-pin HWQFN variants in the RL78/G15 family, including R5F12048ANA#40 (8 KB flash) and R5F12047GNA#40 (industrial-grade −40°C to +105°C). Pin functions, electrical characteristics, and package dimensions (3 × 3 mm, 0.5-mm pitch) are identical - only flash size and temperature grade differ between these part numbers.
