For engineers reviewing the R5F12017GSP#50 datasheet, R5F12017GSP#50 pinout, R5F12017GSP#50 application, or R5F12017GSP#50 equivalent, key selection criteria include its G-grade −40°C to +105°C operating range, 10-pin LSSOP package with 0.65-mm pitch, 4 KB flash memory size, integrated high-speed on-chip oscillator (±1.0% accuracy at TA = −20 to +85°C), and dual simplified I²C interface capability for sensor hub designs.
Technical Context
The R5F12017GSP#50 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 map spans 1 MB address space with four banks of 8-bit general-purpose registers.
It features a selectable power-on-reset circuit with three voltage thresholds (2.25/2.68/3.02 V), on-chip debug support via TOOL0/TOOLRxD/TOOLTxD pins, and peripheral I/O redirection (PIOR) enabling flexible pin function assignment - including remapping of TI00/TO00, SCK00/SCL00, and SCLA0 across multiple pins without hardware change.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F12017GSP#50?
The R5F12017GSP#50 features a high-speed on-chip oscillator selectable from 1 MHz to 16 MHz. At TA = −20°C to +85°C, its frequency accuracy is ±1.0% over VDD = 2.4 V to 5.5 V. This specification applies specifically to G-grade devices like the R5F12017GSP#50 and enables crystal-free operation in industrial sensor and control applications where moderate timing precision suffices.
Does R5F12017GSP#50 support crystal oscillator input, and if so, what frequency range is supported?
The R5F12017GSP#50 does not include X1/X2 crystal oscillator pins - those are only present on 16-pin and 20-pin RL78/G15 variants (e.g., R5F12047GSP#50). As a 10-pin LSSOP device, the R5F12017GSP#50 relies solely on its internal high-speed on-chip oscillator (1–16 MHz) and low-speed 15 kHz oscillator. External clock input via EXCLK is also unavailable in this pinout configuration.
How many analog input channels and comparator channels does R5F12017GSP#50 provide?
The R5F12017GSP#50 provides 4 analog input channels (ANI0–ANI3) and 1 comparator channel (IVCMP0 with VCOUT0 output). These are mapped to P01, P02, P03, and P04 pins respectively. The internal 0.815 V reference (IVREF0) is available on P04, enabling ratiometric or absolute voltage measurements without external references.
What debug interface does R5F12017GSP#50 use, and how many pins are required?
The R5F12017GSP#50 uses a 3-pin on-chip debug interface: TOOL0 (P40), TOOLRxD (P01), and TOOLTxD (P00). This interface supports full flash programming, real-time debugging, and breakpoint execution without requiring JTAG or SWD headers - reducing board space and test fixture complexity. No external debug probe is needed beyond standard UART-level signaling.
Is R5F12017GSP#50 pin-compatible with other RL78/G15 devices in the same package?
Yes - the R5F12017GSP#50 shares identical pinout and electrical characteristics with R5F12018GSP#50 (8 KB flash) and R5F12017ASP#50 (A-grade, −40°C to +85°C) in the 10-pin LSSOP package. All three support identical peripheral mappings, voltage ratings, and timing behavior, enabling drop-in replacement for flash capacity or temperature grade upgrades without PCB modification.
