Overview
R5F12017MSP#10 from Renesas Electronics is a 10-pin, industrial-grade RL78/G15 16-bit microcontroller with 4 KB code flash, 1 KB RAM, and 1 KB data flash. It operates from 2.4 to 5.5 V, supports −40°C to +125°C ambient temperature (M-grade), integrates an 8/10-bit 4-channel ADC, dual simplified I²C interfaces, UART, and 8-channel 16-bit timer array - deployed in motor control subsystems of HVAC actuators.
For engineers reviewing the R5F12017MSP#10 datasheet, R5F12017MSP#10 pinout, R5F12017MSP#10 application, or R5F12017MSP#10 equivalent, key selection criteria include its LSSOP-10 package, 4 KB flash capacity, M-grade thermal rating, on-chip debug support, and multiplexed analog/digital I/O for space-constrained embedded sensors.
Technical Context
The R5F12017MSP#10 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling minimum instruction execution at 0.0625 μs (16 MHz high-speed on-chip oscillator) or 1.0 μs (1 MHz low-speed mode). Its memory map spans 1 MB address space with four banks of 8-bit general-purpose registers.
Power management includes HALT and STOP modes, selectable power-on-reset (SPOR) with four voltage thresholds, and dedicated low-speed on-chip oscillator (15 kHz) for watchdog operation. Peripheral I/O redirection via PIOR registers enables dynamic function assignment across 8 digital I/O pins including P00–P04, P125, P137, and P40.

FAQ
What is the maximum operating frequency of the R5F12017MSP#10?
The R5F12017MSP#10 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs. External crystal oscillation up to 12 MHz is also supported via X1/X2 pins, though this variant (LSSOP-10) lacks those pins - so only the on-chip oscillator is usable. Frequency selection is configured via option byte bits 0–2.
Does the R5F12017MSP#10 support in-system programming?
Yes, the R5F12017MSP#10 supports full in-system programming via its on-chip debug (OCD) interface using TOOL0, TOOLRxD, and TOOLTxD pins. It enables flash erase/write operations without removing the device from the PCB, and includes flash shield window protection to prevent unauthorized access to secured memory regions during development or field updates.
How many analog input channels does the R5F12017MSP#10 have?
The R5F12017MSP#10 features 4 analog input channels: ANI0, ANI1, ANI2, and ANI3 - mapped to pins P01, P02, P03, and P04 respectively. All support 8/10-bit resolution with internal 0.815 V reference voltage, and operate across the full 2.4–5.5 V supply range - enabling direct sensor interfacing without external signal conditioning.
What is the purpose of the PIOR register in the R5F12017MSP#10?
The Peripheral I/O Redirection (PIOR) register in the R5F12017MSP#10 allows dynamic remapping of secondary functions (e.g., SCL00, SDAA0, TI00) to alternate pins at runtime. This provides PCB layout flexibility and functional redundancy - for example, assigning I²C communication to P02/P03 instead of default P00/P01 - without requiring hardware changes or sacrificing pin count.
Can the R5F12017MSP#10 operate reliably at +125°C?
Yes, the R5F12017MSP#10 is rated for continuous operation from −40°C to +125°C (M-grade industrial qualification). Its electrical specifications - including flash endurance, ADC accuracy, oscillator stability (±1.5% at +85°C to +125°C), and I/O drive strength - are fully guaranteed across this full range, making it suitable for under-hood automotive subsystems or enclosed industrial equipment.
