Product details
Overview
R5F1017AANA#20 from Renesas is a 24-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA in RTC+LVD mode), and integrates 10-bit ADC (6 channels), UART/SPI/I²C interfaces, 8× 16-bit timers, and real-time clock - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F1017AANA#20 datasheet, R5F1017AANA#20 pinout, R5F1017AANA#20 application, or R5F1017AANA#20 equivalent, key selection criteria include its 24-pin HWQFN-0.5 mm pitch package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (A-suffix), and verified support for SNOOZE mode wake-up via serial interface events.
Technical Context
The R5F1017AANA#20 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It uses a single-supply voltage domain and integrates dedicated low-speed on-chip oscillator for watchdog and RTC operation independent of main clock.
Its peripheral set includes two UART channels (one supporting LIN-bus), up to eight CSI/SPI channels, and three I²C channels - all configurable via register-based control without external timing components. The 10-bit ADC features internal 1.45 V reference and selectable sample-and-hold timing aligned to timer triggers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1007AANA#20 | Includes 4 KB data flash memory; identical pinout, package, and peripherals; same 16 KB main flash and 2 KB RAM. | Required where field firmware updates or parameter storage (e.g., calibration data) must persist across power cycles without external EEPROM. | Select R5F1007AANA#20 when non-volatile parameter storage is mandatory; otherwise R5F1017AANA#20 reduces cost and simplifies qualification. |
| RL78/G14 R5F104GCAANA#20 | Same 24-pin HWQFN package but with 48 KB flash, 4 KB RAM, and added 12-bit ADC; higher DMIPS (62) and enhanced DMA (4-channel). | Preferred for designs anticipating feature expansion (e.g., adding OTA updates or advanced motor control algorithms) within same footprint. | Choose R5F104GCAANA#20 only if future scalability justifies higher BOM cost; R5F1017AANA#20 remains optimal for stable, cost-sensitive volume production. |
Compared with R5F1007AANA#20, the R5F1017AANA#20 omits data flash to reduce die size and cost while retaining identical low-power behavior and peripheral compatibility; versus R5F104GCAANA#20, it trades memory headroom and ADC resolution for lower static power and simpler toolchain validation.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F1017AANA#20?
The R5F1017AANA#20 operates up to 32 MHz with 41 DMIPS performance and consumes 66 μA per MHz in active mode. At full speed with all peripherals enabled, typical current draw is 2.1 mA (VDD = 3.3 V, TA = 25°C), dropping to 0.57 μA in STOP mode with RTC and LVD active - verified in Renesas Application Note R01AN3103.
Does the R5F1017AANA#20 support in-system programming without external tools?
Yes, the R5F1017AANA#20 supports single-pin UART bootloader mode via P11 (TOOLRxD) and P12 (TOOLTxD). Using Renesas Flash Development Toolkit (FDT) or third-party UART utilities, firmware can be updated in-circuit without JTAG debugger - confirmed in Section 26.3 of R01DS0131EJ0380 datasheet.
What are the supported clock sources for the R5F1017AANA#20?
The R5F1017AANA#20 integrates a high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy), a 32.768 kHz sub-system oscillator for RTC, and supports external crystal (up to 20 MHz) or ceramic resonator inputs. No PLL is included; clock dividers enable fractional prescaling for peripheral synchronization.
Can the R5F1017AANA#20 drive LEDs directly from its I/O pins?
Yes, several I/O pins on the R5F1017AANA#20 support N-ch open-drain configuration with 6 V tolerance, allowing direct connection to common-anode LED circuits with current-limiting resistors. Maximum sink current per pin is 20 mA (DC), with total package limit of 100 mA - specified in Absolute Maximum Ratings Table 14.1.
Is there hardware support for cryptographic operations in the R5F1017AANA#20?
No, the R5F1017AANA#20 does not include dedicated cryptographic accelerators (AES, SHA, RNG). Security relies on flash lock bits, LVD reset protection, and software-implemented algorithms. For hardware crypto, Renesas recommends RL78/G1M or RA2 series MCUs - explicitly stated in Section 1.1 "Features" of R01DS0131EJ0380.
