Overview
R5F12017GSP#10 from Renesas Electronics is a 10-pin LSSOP, 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 V to 5.5 V, supports −40°C to +105°C ambient temperature (G-grade), and integrates an 8-channel 16-bit timer array, 4-channel 8/10-bit ADC, and UART + dual simplified I²C + dual CSI interfaces - deployed in smart sensor nodes and low-power industrial control modules.
For engineers reviewing the R5F12017GSP#10 datasheet, R5F12017GSP#10 pinout, R5F12017GSP#10 application, or R5F12017GSP#10 equivalent, this page delivers verified functional scope, validated pin mapping for LSSOP-10, real-world timing and analog performance metrics, and direct alternative part comparisons grounded in Renesas' official RL78/G15 family documentation.
Technical Context
The R5F12017GSP#10 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 subsystem includes 4 KB code flash (1 KB block erase), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 1 KB SRAM - all accessible under single-supply operation without external voltage regulators.
Peripherals are tightly integrated via the TAU0 timer array (8 channels), SAU0 serial array unit (supporting UART, CSI, and simplified I²C), and independent comparator and ADC subsystems. Power management includes HALT/STOP modes, selectable power-on-reset (SPOR) with four voltage thresholds, and dedicated low-speed 15 kHz oscillator for watchdog operation - all compliant with industrial thermal and voltage stress requirements.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F12017GSP#10?
The R5F12017GSP#10 features a high-speed on-chip oscillator selectable from 1 MHz to 16 MHz. At its maximum 16 MHz setting, frequency accuracy is ±1.0% over TA = −20°C to +85°C (industrial G-grade), and ±1.5% across the full −40°C to +105°C range. This eliminates external crystal cost while meeting timing requirements for UART, PWM, and sensor sampling in most industrial applications.
Does R5F12017GSP#10 support in-system programming of its flash memory?
Yes, R5F12017GSP#10 supports full in-system programming of both code flash (4 KB) and data flash (1 KB) without external high-voltage supplies. It enables firmware updates via UART or other serial interfaces using the built-in self-programming function - critical for remote device maintenance and field-deployed industrial equipment.
How many analog input channels does R5F12017GSP#10 provide, and what reference options are available?
R5F12017GSP#10 provides 4 analog input channels (ANI0–ANI3) with 8/10-bit resolution. Reference voltage options include the supply rail (VDD) or an internal 0.815 V (TYP.) reference - selectable per channel. This allows ratiometric sensor measurements and stable low-voltage analog acquisition without external reference ICs.
What debug interface does R5F12017GSP#10 use, and is external hardware required?
R5F12017GSP#10 uses Renesas' on-chip debug interface accessed through dedicated TOOL0, TOOLRxD, and TOOLTxD pins. No external JTAG emulator is required - standard UART-to-USB adapters suffice for full debugging, flash programming, and real-time variable monitoring using e² studio or CS+ IDE.
Can R5F12017GSP#10 operate reliably at 105°C ambient temperature?
Yes, R5F12017GSP#10 is rated for industrial-grade operation from −40°C to +105°C (G-grade). Its electrical specifications, including flash endurance, ADC linearity, and oscillator stability, are guaranteed across this full range - making it suitable for deployment inside sealed enclosures, motor control cabinets, and outdoor industrial housings.
