Renesas R5F1017EANA#20

Overview

R5F1017EANA#20 from Renesas is a 24-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 2 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 8/10-bit ADC (10 channels), UART/SPI/I²C interfaces, and operates from 1.6–5.5 V for battery-powered industrial sensors and smart meters.

For engineers reviewing the R5F1017EANA#20 datasheet, R5F1017EANA#20 pinout, R5F1017EANA#20 application, or R5F1017EANA#20 equivalent, key selection criteria include its 24-pin HWQFN-0.5 mm pitch package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for SNOOZE mode for low-latency wake-up in energy-constrained edge nodes.

Technical Context

The R5F1017EANA#20 implements the RL78 CPU core with 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 architecture separates 64 KB code flash (1 KB blocks) from 2 KB SRAM and omits data flash-unlike R5F100x variants-relying on external storage or flash self-programming via boot swap.

Peripherals include eight 16-bit timers, one real-time clock with calendar/alarm, 10-channel 8/10-bit ADC with internal 1.45 V reference, and three serial interfaces (CSI, UART/LIN, I²C), all configurable under HALT/STOP/SNOOZE power modes. The device uses a single 1.6–5.5 V supply with on-chip POR and 14-level LVD.

FAQ

What is the maximum operating frequency of the R5F1017EANA#20?

The R5F1017EANA#20 supports a maximum system clock frequency of 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS performance. External crystals up to 20 MHz can also be used, and the subsystem clock runs at 32.768 kHz for RTC operation. All timing specifications-including ADC conversion time and UART baud generation-are validated across this range per the R01DS0131EJ0380 datasheet.

Does the R5F1017EANA#20 include on-chip data flash memory?

No, the R5F1017EANA#20 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number (per Figure 1-1 of R01DS0131EJ0380), it belongs to the data-flash-less variant family. It provides 64 KB code flash and 2 KB SRAM only. For applications requiring nonvolatile parameter storage, R5F1007EANA#20 (with 4 KB data flash) is the functional counterpart.

What package type and pin pitch does the R5F1017EANA#20 use?

The R5F1017EANA#20 uses a 24-pin HWQFN package (4 × 4 mm body, 0.5 mm pin pitch), identified by the "NA" suffix and #20 tray packaging code. This package features an exposed thermal pad, supports reflow soldering, and complies with JEDEC standards for moisture sensitivity level MSL3. Pin configuration matches other 24-pin RL78/G13 devices per datasheet Section 1.3.1.

Can the R5F1017EANA#20 operate from a single 1.8 V supply?

Yes, the R5F1017EANA#20 operates from 1.6 V to 5.5 V, so 1.8 V is within its valid supply range. At 1.8 V, the maximum supported CPU frequency is 16 MHz (per Section 1.1 "Features"), and ADC operation remains functional with adjusted reference scaling. The device maintains full peripheral functionality-including UART, timers, and GPIO-across this voltage range, making it suitable for single-cell lithium or NiMH systems.

How many analog input channels does the R5F1017EANA#20 support?

The R5F1017EANA#20 supports 10 analog input channels, as confirmed in Table 1-1 of the R01DS0131EJ0380 datasheet for 24-pin variants. These channels map to pins P13–P15, P20–P22, P30–P33, and P37. The integrated 8/10-bit ADC includes internal 1.45 V reference and temperature sensor, with sampling controlled via hardware triggers or software polling.
