Product details
Overview
R5F12017MSP#50 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 2.4–5.5 V, supports −40°C to +125°C ambient, integrates an 8/10-bit 4-channel ADC, 8-channel 16-bit timer, UART, two simplified SPI (CSI) channels, and two simplified I²C channels - deployed in motor control subsystems for HVAC actuators.
For engineers reviewing the R5F12017MSP#50 datasheet, R5F12017MSP#50 pinout, R5F12017MSP#50 application, or R5F12017MSP#50 equivalent, key selection criteria include its M-grade temperature rating, 10-pin LSSOP package with 0.65-mm pitch, on-chip debug support, low-power HALT/STOP modes, and integrated comparator with internal reference voltage.
Technical Context
The R5F12017MSP#50 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 uses a high-speed on-chip oscillator selectable from 1–16 MHz with ±1.0% accuracy over −20°C to +85°C and ±1.5% over −40°C to −20°C or +85°C to +125°C.
Power management includes selectable power-on-reset (SPOR) with four detection voltage levels, HALT and STOP low-power modes, and a dedicated 15-kHz low-speed on-chip oscillator for watchdog operation. Peripheral I/O redirection (PIOR) enables dynamic remapping of functions like TI00/TO00 and SCK00/SCL00 across pins P02–P04.

FAQ
What is the maximum operating frequency and instruction execution time of the R5F12017MSP#50?
The R5F12017MSP#50 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs. This timing assumes high-speed on-chip oscillator operation with no wait states; actual performance depends on flash wait-state configuration and bus arbitration.
Does the R5F12017MSP#50 support external crystal oscillation?
Yes, the R5F12017MSP#50 supports external crystal oscillation via X1/X2 pins - but only on 16-pin and 20-pin variants. The 10-pin R5F12017MSP#50 lacks X1/X2 pins and relies solely on its high-speed on-chip oscillator (1–16 MHz) and low-speed 15-kHz internal oscillator.
How many analog input channels does the R5F12017MSP#50 provide?
The R5F12017MSP#50 provides four analog input channels (ANI0–ANI3), accessible on pins P01, P02, P03, and P04. All channels support 8/10-bit resolution and can use either the internal 0.815 V reference (IVREF0) or external reference voltage.
Can the R5F12017MSP#50 perform in-system programming of its flash memory?
Yes, the R5F12017MSP#50 supports self-programming of both code flash and data flash memory in-system. It includes flash shield window functionality for intellectual property protection and requires no boot swap mechanism - enabling secure firmware updates during normal operation.
What debug interface does the R5F12017MSP#50 use, and how is it connected?
The R5F12017MSP#50 uses an on-chip debug interface accessed via three dedicated pins: TOOL0 (P40), TOOLRxD (P01), and TOOLTxD (P00). These pins support programming, real-time debugging, and trace without requiring external JTAG or SWD adapters - simplifying development and reducing BOM cost.
