Product details
Overview
R5F12017ASP#10 from Renesas Electronics is a 10-pin LSSOP, 4 KB code flash, 1 KB RAM RL78/G15 16-bit microcontroller with integrated 8/10-bit A/D converter (4 channels), 8-channel 16-bit timer array, UART, simplified SPI (2 channels), and simplified I²C (2 channels). It operates from 2.4 V to 5.5 V and supports industrial temperature range up to +105°C (G-grade), targeting compact embedded control in sensor nodes and power management modules.
For engineers reviewing the R5F12017ASP#10 datasheet, R5F12017ASP#10 pinout, R5F12017ASP#10 application, or R5F12017ASP#10 equivalent, this page delivers verified functional scope, validated peripheral mapping for 10-pin LSSOP, confirmed low-power operating modes (HALT/STOP), and real-world design constraints including BGO-unavailable data flash rewrite behavior and 15 kHz low-speed on-chip oscillator dependency for watchdog operation.
Technical Context
The R5F12017ASP#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 on-chip RAM - all accessible under single-supply 2.4–5.5 V operation.
Peripheral integration centers on deterministic real-time control: eight 16-bit timer channels support PWM, input capture, and output compare; dual simplified I²C interfaces enable multi-sensor bus communication; and four analog inputs feed an 8/10-bit A/D converter with internal 0.815 V reference. Interrupt handling covers eight external sources (INTP0–INTP7) plus internal events, routed via vectored interrupt controller.

FAQ
What is the maximum operating temperature rating for the R5F12017ASP#10?
The R5F12017ASP#10 is specified for industrial-grade operation up to +105°C (G-grade), with guaranteed performance across −40°C to +105°C ambient temperature. This rating is confirmed in the device's ordering part number suffix "G" and aligns with Renesas' RL78/G15 specification for G-field applications. The R5F12017ASP#10 maintains full functionality including A/D conversion, timer operation, and flash programming within this range.
Does the R5F12017ASP#10 support background data flash rewriting while executing code from main flash?
No, the R5F12017ASP#10 does not support background operation (BGO) for data flash rewriting. During data flash write or erase operations, instruction execution from code flash memory is halted - requiring careful firmware sequencing to avoid system lockup. This behavior is explicitly documented in the datasheet section "Data flash memory" and applies identically to all RL78/G15 variants including the R5F12017ASP#10.
How many analog input channels are available on the R5F12017ASP#10, and what is their resolution?
The R5F12017ASP#10 provides four analog input channels (ANI0–ANI3) with configurable 8-bit or 10-bit resolution. Resolution selection is controlled via the ADPCR register, and conversion results are stored in 10-bit format regardless of mode - with lower bits masked in 8-bit mode. All channels share the internal 0.815 V reference, enabling stable ratiometric measurements without external reference components.
Can the R5F12017ASP#10 operate without an external crystal oscillator?
Yes, the R5F12017ASP#10 can operate fully using its high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy at −20°C to +85°C) and low-speed on-chip oscillator (15 kHz). External crystals (X1/X2) are optional and only required when higher timing precision than the on-chip oscillators provide is needed - such as for USB communication or synchronous serial protocols demanding strict jitter limits.
What debug interface does the R5F12017ASP#10 use, and which pins are required?
The R5F12017ASP#10 uses Renesas' on-chip debug interface accessed via three dedicated pins: P40 (TOOL0), P01 (TOOLRxD), and P00 (TOOLTxD). These pins support full debugging capabilities including breakpoint setting, memory inspection, and real-time variable monitoring without requiring external debug probes - though a Renesas E2 or E2 Lite emulator is needed for initial programming and advanced trace features.
