Overview
R5F1017EANA#40 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 3 KB RAM, 16-channel 10-bit ADC, and real-time clock - designed for ultra-low-power industrial control and sensor interface applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F1017EANA#40 datasheet, R5F1017EANA#40 pinout, R5F1017EANA#40 application, or R5F1017EANA#40 equivalent, key selection criteria include its 0.57 μA STOP mode current, 40-pin 6 × 6 mm HWQFN package, integrated RTC with calendar/alarm, on-chip debug support, and dual-voltage I/O capability (1.8/2.5/3.0 V interface).
Technical Context
The R5F1017EANA#40 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), DMA controller (2 channels), and multiply-accumulate unit supporting 16×16→32-bit operations.
Its peripheral set includes up to 16× 16-bit timers, 3× UART/LIN interfaces, 10× I²C/Simplified I²C channels, 2× CSI/SPI interfaces, and a background operation-capable data flash memory enabling concurrent code execution during rewrites - all optimized for deterministic real-time response in battery-powered systems.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F1017EANA#40?
The R5F1017EANA#40 operates up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. At this speed, typical active current is 66 μA per MHz - resulting in ~2.1 mA total at 32 MHz with all peripherals disabled. The device also supports ultra-low-speed modes down to 32.768 kHz for RTC operation at sub-μA levels.
Does the R5F1017EANA#40 include an integrated real-time clock (RTC)?
Yes, the R5F1017EANA#40 includes a fully featured RTC with calendar support (99-year range), alarm interrupt, and clock correction function. It operates independently in STOP mode using the 32.768 kHz subsystem clock, consuming only 0.57 μA - enabling accurate timekeeping during ultra-low-power sleep states without external components.
Can the R5F1017EANA#40 perform flash memory writes while executing code from flash?
Yes, the R5F1017EANA#40 supports background operation (BGO) for data flash memory. This allows the CPU to execute instructions from code flash while simultaneously rewriting data flash - critical for applications requiring continuous operation during firmware updates or parameter logging without interruption.
What is the I/O voltage tolerance and interface capability of the R5F1017EANA#40?
The R5F1017EANA#40 supports different-potential interface: its I/O ports can safely connect to 1.8 V, 2.5 V, or 3.0 V devices while powered from 1.6–5.5 V. Input buffers accept TTL-level signals, and selected pins support N-ch open-drain configuration with 6 V withstand voltage - simplifying level-shifting in mixed-voltage systems.
Is the R5F1017EANA#40 pin-compatible with other RL78/G13 variants in the 40-pin HWQFN package?
Yes, all RL78/G13 40-pin HWQFN variants - including R5F1007EANA#40, R5F1017EANA#40, and R5F1017DANA#40 - share identical pinout and footprint. Differences are limited to memory configuration (code flash, data flash, RAM) and temperature grade (D vs A), enabling drop-in replacement during design iteration or qualification.
