Overview
R5F12047ASP#10 from Renesas Electronics is a 16-pin, 4 KB code flash, 1 KB RAM RL78/G15 16-bit microcontroller with 7-channel 8/10-bit ADC, dual simplified I²C, dual CSI (SPI-compatible), UART, and 8-channel 16-bit timer array - designed for industrial sensor nodes and low-power HMI control at VDD = 2.4–5.5 V.
For engineers reviewing the R5F12047ASP#10 datasheet, R5F12047ASP#10 pinout, R5F12047ASP#10 application, or R5F12047ASP#10 equivalent, key selection criteria include its 16-pin SSOP package, 4 KB flash / 1 KB data flash / 1 KB RAM memory map, −40°C to +105°C industrial temperature grade (G), integrated high-speed on-chip oscillator (±1.0% @ −20°C to +85°C), and multiplexed analog/digital I/O supporting up to 7 ADC inputs and 2 comparator channels.
Technical Context
The R5F12047ASP#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It supports HALT and STOP low-power modes, selectable power-on-reset (SPOR) with four voltage thresholds, and on-chip debug via TOOL0/TOOLRxD/TOOLTxD pins.
Its clock system integrates a high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy in G-grade), low-speed 15 kHz on-chip oscillator, and external crystal support (X1/X2, 1–12 MHz). Peripheral I/O redirection (PIOR) enables flexible pin function assignment across its 14 digital I/O ports, including N-ch open-drain capability with VDD-tolerant outputs.

FAQ
What is the maximum operating frequency of the R5F12047ASP#10's high-speed on-chip oscillator?
The R5F12047ASP#10 supports a high-speed on-chip oscillator frequency of up to 16 MHz, selectable via option byte bits 0–2. Its accuracy is ±1.0% over −20°C to +85°C for G-grade operation, enabling reliable timing without external crystals in many applications.
Does the R5F12047ASP#10 support background operation during data flash rewriting?
No, the R5F12047ASP#10 does not support background operation (BGO) during data flash rewriting. Instructions cannot be executed from code flash memory while data flash is being rewritten, requiring careful state management in firmware to avoid execution stalls.
How many analog input channels does the R5F12047ASP#10 provide, and what is their resolution?
The R5F12047ASP#10 provides 7 analog input channels (ANI0–ANI6) with selectable 8-bit or 10-bit resolution. It includes an internal 0.815 V reference voltage and supports external reference inputs (IVREF0/IVREF1) for improved measurement accuracy.
What is the purpose of the PCLBUZ0 function on the R5F12047ASP#10?
The PCLBUZ0 function on the R5F12047ASP#10 enables programmable clock or buzzer output generation, supporting frequencies up to 10 MHz. It can be assigned to pins P02 or P06 via peripheral I/O redirection register (PIOR) settings for audible alerts or clock distribution.
Is the R5F12047ASP#10 pin-compatible with other RL78/G15 16-pin variants like R5F12048ASP#10?
Yes, the R5F12047ASP#10 is fully pin-compatible with R5F12048ASP#10 - both use the same 16-pin SSOP package, identical pin configuration, and shared peripheral mapping. The only difference is code flash capacity (4 KB vs. 8 KB), allowing seamless hardware reuse.
