Overview
R5F12047ANA#00 from Renesas Electronics is a 16-pin HWQFN-packaged RL78/G15 16-bit microcontroller with 4 KB code flash, 1 KB RAM, and 1 KB data flash. It operates from 2.4 V to 5.5 V, supports HALT/STOP low-power modes, and integrates an 8/10-bit A/D converter (7 channels), 8-channel 16-bit timer array, UART, simplified I²C, and simplified SPI - used in industrial sensor nodes requiring compact size, deterministic timing, and extended temperature operation.
For engineers reviewing the R5F12047ANA#00 datasheet, R5F12047ANA#00 pinout, R5F12047ANA#00 application, or R5F12047ANA#00 equivalent, key selection criteria include its 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, −40°C to +125°C M-grade qualification, 4 KB flash capacity, on-chip debug support, and multiplexed analog/digital I/O for cost-sensitive embedded control.
Technical Context
The R5F12047ANA#00 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.0625 μs at 16 MHz using the high-speed on-chip oscillator. Its memory map includes 1 MB address space, with dedicated code and data flash blocks (1 KB erase/write units) and no background operation during data flash rewrite.
It features dual-oscillator support: selectable high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy at −20°C to +85°C for M-grade), low-speed on-chip oscillator (15 kHz), and external crystal interface (X1/X2, 1–12 MHz). Peripheral integration includes 7-channel A/D converter with internal reference (0.815 V), two comparators, and programmable clock/buzzer output (PCLBUZ0).

FAQ
What is the maximum operating frequency of the R5F12047ANA#00?
The R5F12047ANA#00 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% for M-grade within −20°C to +85°C.
Does the R5F12047ANA#00 support in-system programming via its debug interface?
Yes, the R5F12047ANA#00 supports full on-chip debug and self-programming via the TOOL0, TOOLRxD, and TOOLTxD pins. It enables firmware updates and debugging without external emulators. However, Renesas cautions against using the on-chip debug function in mass-produced end products due to potential flash endurance impact from repeated debug access - R5F12047ANA#00 is qualified for production use with standard programming methods.
How many analog input channels does the R5F12047ANA#00 support, and what reference options are available?
The R5F12047ANA#00 supports 7 analog input channels (ANI0–ANI6) with 8/10-bit resolution. It provides an internal reference voltage of 0.815 V (typical) and allows selection of external reference inputs (IVREF0, IVREF1) for comparator circuits. The A/D converter operates across the full VDD range (2.4–5.5 V), ensuring consistent performance under varying supply conditions in R5F12047ANA#00 designs.
What is the purpose of the PCLBUZ0 function on the R5F12047ANA#00?
PCLBUZ0 is the programmable clock/buzzer output function assigned to pins such as P02 and P41 on the R5F12047ANA#00. It generates precise square-wave tones for audible alerts without CPU intervention, supporting frequencies up to 10 MHz. This hardware-peripheral capability offloads timing-critical buzzer control from firmware, conserving CPU cycles in resource-constrained applications using R5F12047ANA#00.
Can the R5F12047ANA#00 operate reliably at +125°C ambient temperature?
Yes, the R5F12047ANA#00 is an M-grade device qualified for continuous operation from −40°C to +125°C, meeting industrial requirements for harsh thermal environments. Its electrical specifications - including flash endurance, oscillator accuracy (±1.5% at +85°C to +125°C), and DC characteristics - are guaranteed across this full range, making R5F12047ANA#00 suitable for under-hood automotive subsystems and enclosed industrial enclosures.
