Renesas R5F1017CDNA#U0

Overview

R5F1017CDNA#U0 from Renesas is a 24-pin RL78/G13 16-bit microcontroller with 32 KB flash memory, 2 KB RAM, and no data flash, designed for ultra-low-power industrial applications (−40°C to +85°C). It features a 32 MHz RL78 CPU core delivering 41 DMIPS, 66 μA/MHz active current, 0.57 μA RTC+LVD standby, and integrated peripherals including 10-bit ADC (6 channels), UART, I²C, CSI, 16-bit timers, and real-time clock.

For engineers reviewing the R5F1017CDNA#U0 datasheet, R5F1017CDNA#U0 pinout, R5F1017CDNA#U0 application, or R5F1017CDNA#U0 equivalent, key selection criteria include its HWQFN-24 (4 × 4 mm, 0.5 mm pitch) package, absence of data flash, industrial temperature grade (D), and suitability for battery-powered sensor nodes, smart meters, and embedded control where low active/standby power and compact footprint are critical.

Technical Context

The R5F1017CDNA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting variable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It integrates on-chip power management with HALT, STOP, and SNOOZE low-power modes, plus an on-chip voltage detector (LVD) with 14 selectable levels and POR circuit.

Peripherals include a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, up to 16 I/O ports (N-ch open-drain capable), 2–4 channel DMA, 16-bit timer array (8–16 channels), real-time clock with calendar/alarm, and serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C/Simplified I²C (3–10 channels).

FAQ

Does R5F1017CDNA#U0 include data flash memory?

No, R5F1017CDNA#U0 does not include data flash memory. As indicated by the "101" prefix in its part number per Renesas documentation, this variant provides only 32 KB of code flash memory and 2 KB of RAM. Data flash (4–8 KB) is present only in "100" series parts like R5F1007CDNA#U0. Firmware parameter storage must be implemented externally or in reserved code flash sectors with wear-leveling software.

What is the maximum operating frequency and corresponding performance of R5F1017CDNA#U0?

R5F1017CDNA#U0 operates at up to 32 MHz using the high-speed on-chip oscillator, achieving 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under these conditions. The core also supports ultra-low-speed operation at 32.768 kHz (30.5 μs/instruction) for RTC and LVD-only functions, enabling flexible power/performance trade-offs.

Which package type and pin count does R5F1017CDNA#U0 use?

R5F1017CDNA#U0 uses a 24-pin HWQFN package (4 × 4 mm, 0.5 mm pitch) with wettable flanks, identified by the "NA" suffix and "#U0" tray packaging code. This compact, thermally efficient package is optimized for automated SMT assembly and space-constrained applications such as portable medical devices and smart utility modules.

What industrial temperature range is supported by R5F1017CDNA#U0?

R5F1017CDNA#U0 is rated for industrial operation from −40°C to +85°C, denoted by the "D" grade in its part number. This qualification ensures reliable functionality in demanding environments such as factory floor controllers, outdoor metering equipment, and HVAC systems where ambient thermal stress exceeds commercial-grade limits.

Can R5F1017CDNA#U0 drive external components directly from its I/O pins?

Yes, R5F1017CDNA#U0 supports N-ch open-drain output configuration on selected I/O pins (e.g., P10, P11), enabling direct interface with external pull-up loads such as LEDs, I²C buses, or level-shifted logic. Its I/O structure tolerates 6 V on specific pins and supports different-potential interfaces (1.8 V/2.5 V/3 V), allowing safe connection to mixed-voltage peripherals without external translators.
