Overview
R5F12047GSP#10 from Renesas Electronics is a 16-pin, 4 KB code flash, 1 KB RAM RL78/G15 16-bit microcontroller with industrial-grade temperature range (−40°C to +105°C), high-speed on-chip oscillator (1–16 MHz), 7-channel 8/10-bit ADC, and dual simplified I²C/SPI interfaces. It targets low-power embedded control in motor drives, sensor nodes, and industrial HMI.
For engineers reviewing the R5F12047GSP#10 datasheet, R5F12047GSP#10 pinout, R5F12047GSP#10 application, or R5F12047GSP#10 equivalent, key selection criteria include its 16-pin LSSOP package, 4 KB flash / 1 KB data flash memory partitioning, integrated comparator and buzzer output, and support for both STOP and HALT low-power modes under VDD = 2.4–5.5 V operation.
Technical Context
The R5F12047GSP#10 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction execution time (0.0625 μs at 16 MHz to 1.0 μs at 1 MHz). It integrates a selectable power-on-reset circuit with four voltage thresholds and supports peripheral I/O redirection via PIOR registers for flexible pin assignment.
Its timing subsystem includes an 8-channel 16-bit timer array unit (TAU0), a 12-bit interval timer, and a watchdog timer operable from the dedicated 15 kHz low-speed on-chip oscillator. Serial connectivity comprises two simplified SPI (CSI) channels, two simplified I²C channels, one full I²C channel, and one UART channel - all mapped across 14 GPIO pins with interrupt capability (INTP0–INTP7).

FAQ
What is the maximum operating frequency of the R5F12047GSP#10 high-speed on-chip oscillator?
The R5F12047GSP#10 high-speed on-chip oscillator supports frequencies from 1 MHz to 16 MHz, with ±1.0% accuracy over −20°C to +85°C (industrial G-grade). Frequency selection is configured via bits 0–2 of option byte 00C2H, and the oscillator operates across the full VDD range of 2.4 V to 5.5 V without external components.
Does the R5F12047GSP#10 support background data flash rewriting during code execution?
No, the R5F12047GSP#10 does not support background operation (BGO) for data flash rewriting. While executing instructions from code flash memory, data flash programming or erasure is blocked - the CPU must halt or switch to RAM-based execution during flash operations. This behavior is explicitly documented in the datasheet section on data flash memory.
How many analog input channels are available on the R5F12047GSP#10, and what is their resolution?
The R5F12047GSP#10 provides 7 analog input channels (ANI0 through ANI6), supporting either 8-bit or 10-bit resolution depending on configuration. The ADC uses VDD as the reference by default but can also accept an internal 0.815 V reference (IVREF0) or external reference for ratiometric measurements.
Can the R5F12047GSP#10 operate in STOP mode with the watchdog timer active?
Yes, the R5F12047GSP#10 supports watchdog timer operation during STOP mode using the dedicated 15 kHz low-speed on-chip oscillator. This allows reliable timeout supervision while consuming sub-1 μA current - critical for battery-backed safety-critical applications where deep sleep must remain monitorable.
What is the pin-compatible alternative to the R5F12047GSP#10 with increased flash memory?
The R5F12048GSP#10 is a pin-compatible alternative to the R5F12047GSP#10, offering identical 16-pin LSSOP packaging, peripheral set, and industrial −40°C to +105°C rating, but with 8 KB of code flash memory instead of 4 KB. No PCB or firmware changes are required beyond recompilation for the larger memory map.
