Product details
Overview
R5F1017AANA#40 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 HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), and integrates 10-bit ADC (6 channels), RTC, UART, I²C, and 16-bit timers for embedded control in battery-powered industrial sensors.
For engineers reviewing the R5F1017AANA#40 datasheet, R5F1017AANA#40 pinout, R5F1017AANA#40 application, or R5F1017AANA#40 equivalent, key selection criteria include its 24-pin HWQFN (6 × 6 mm, 0.5-mm pitch) package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (A-suffix), and support for background data flash programming in compatible variants.
Technical Context
The R5F1017AANA#40 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with 16 KB code flash organized in 1 KB blocks and 2 KB on-chip RAM.
Power management includes an on-chip POR circuit and voltage detector (LVD) with 14 selectable interrupt/reset levels. Peripheral integration comprises two UART channels (LIN-capable), up to ten I²C/Simplified I²C channels, eight to sixteen 16-bit timers, and a 10-bit A/D converter with internal 1.45 V reference and temperature sensor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline and 1 MB address space |
| Max Operating Frequency | 32 MHz delivering 41 DMIPS - enables real-time control loop execution within sub-μs timing budgets |
| Flash Memory | 16 KB code flash in 1 KB blocks - sufficient for compact firmware with secure block erase prohibition |
| RAM Size | 2 KB on-chip RAM - supports moderate stack depth and data buffering for sensor fusion or protocol stacks |
| Supply Voltage Range | 1.6 V to 5.5 V - allows direct interface with 1.8 V, 3.3 V, and 5 V logic domains without level shifters |
| Low-Power Modes | HALT (66 μA/MHz), STOP (0.57 μA with RTC+LVD active) - extends battery life in always-on monitoring applications |

Pinout & Package
Package: 24-pin HWQFN (6 × 6 mm, 0.5-mm pitch), moisture sensitivity level MSL3, RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | Main digital supply (1.6–5.5 V); decoupling required per Renesas layout guidelines |
| VSS | Ground | Digital ground reference; must be connected to low-impedance PCB plane |
| RESET | Reset input | Active-low reset with internal pull-up; accepts external debounced pushbutton or supervisor IC |
| P10/SCK00/SCL00 | Port 10 multifunction pin | Configurable as SPI clock, I²C clock, or general-purpose I/O - shared peripheral reduces pin count |

| P20/ANI0/AVREFP | Analog input 0 / ADC reference positive | Primary analog input channel; AVREFP setting defines ADC full-scale range for precision measurements |
| P21/ANI1/AVREFM | Analog input 1 / ADC reference negative | Second analog input; AVREFM sets lower reference bound - enables ratiometric or differential sensing |
| XTAL1/XT1 | Crystal oscillator input | Connects to external 32.768 kHz crystal for RTC accuracy; requires load capacitors per crystal spec |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1016AANA#40 | 20-pin HWQFN, same 16 KB flash/2 KB RAM/no data flash, but 2 fewer I/O pins and no P11 multifunction capability | Limited peripheral routing due to reduced pin count; unsuitable for designs requiring dual UART + I²C simultaneously | Select when board space is critical and I/O count ≤16 suffices; shares identical power/performance envelope |
| R5F1017DANA#40 | Same 24-pin HWQFN package and memory, but rated for -40°C to +85°C industrial (D-suffix) with enhanced ESD tolerance | Validated for harsher environments (e.g., factory floor, outdoor enclosures) where A-grade reliability is insufficient | Choose for deployments requiring extended temperature stability and higher immunity to electrostatic discharge events |
Compared with R5F1016AANA#40, the R5F1017AANA#40 provides four additional GPIOs and expanded serial peripheral flexibility; versus R5F1017DANA#40, it offers identical functionality at lower qualification cost for commercial-grade applications.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F1017AANA#40?
The R5F1017AANA#40 operates at up to 32 MHz, achieving 41 DMIPS (Dhrystone MIPS) performance. This speed is enabled by the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The device maintains this performance across its full 1.6 V to 5.5 V supply range and -40°C to +85°C ambient temperature, making R5F1017AANA#40 suitable for deterministic real-time control tasks in resource-constrained systems.
Does the R5F1017AANA#40 include on-chip data flash memory?
No, the R5F1017AANA#40 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number (per Renesas RL78/G13 documentation), this variant provides only 16 KB of code flash and 2 KB of RAM. Data storage must be implemented externally or via code flash emulation techniques. For applications requiring persistent nonvolatile data storage, consider R5F1007AANA#40 (which includes 4 KB data flash) instead of R5F1017AANA#40.
What package type and pin count does the R5F1017AANA#40 use?
The R5F1017AANA#40 uses a 24-pin HWQFN package measuring 6 mm × 6 mm with 0.5 mm pitch. This package is designated "NA" in Renesas' ordering nomenclature and is supplied in embossed tape (#40 suffix). Its compact footprint and exposed thermal pad support high-density PCB layouts while enabling efficient heat dissipation in thermally constrained applications - a key physical attribute distinguishing R5F1017AANA#40 from larger 32- or 40-pin RL78/G13 variants.
What low-power modes are supported by the R5F1017AANA#40, and what are their typical current draws?
The R5F1017AANA#40 supports HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode (intermediate power state with selected peripherals running). These modes are controlled via dedicated system registers and respond to wake-up sources including external interrupts, RTC alarms, and LVD events. The 0.57 μA STOP current makes R5F1017AANA#40 especially effective in applications like wireless sensor nodes where periodic wake-up and measurement dominate power budget calculations.
Can the R5F1017AANA#40 operate with a 32.768 kHz external crystal for RTC functionality?
Yes, the R5F1017AANA#40 supports external 32.768 kHz crystal connection on XTAL1/XT1 pins for precise real-time clock operation. When configured, the RTC provides calendar functions (year/month/day/hour/minute/second), alarm generation, and clock correction - all while consuming only 0.57 μA in STOP mode. This capability is fully documented in the R5F1017AANA#40's electrical characteristics table and is independent of the main system clock source, ensuring R5F1017AANA#40 maintains accurate timekeeping during ultra-low-power operation.
