Product details
Overview
R5F101EDDNA#U0 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 32 KB flash memory, 2 KB RAM, and no data flash. It operates from 1.6 V to 5.5 V, achieves 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD-only operation), targeting battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101EDDNA#U0 datasheet, R5F101EDDNA#U0 pinout, R5F101EDDNA#U0 application, or R5F101EDDNA#U0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, absence of data flash, industrial-grade −40°C to +85°C temperature rating (D suffix), and integrated 10-bit ADC with 26-channel analog input capability.
Technical Context
The R5F101EDDNA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space, with on-chip RAM banked across four register banks.
It integrates a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 16-bit timers (up to 16 channels), real-time clock with calendar/alarm functions, and multiple serial interfaces including UART/LIN, CSI (SPI-compatible), and I²C - all configurable without external components for embedded control.

FAQ
What is the operating temperature range for the R5F101EDDNA#U0?
The R5F101EDDNA#U0 is rated for industrial operation from −40°C to +85°C, as indicated by the 'D' suffix in its part number. This range is validated per Renesas specification R01DS0131EJ0380 and supports deployment in harsh environments such as factory floors and outdoor utility enclosures without derating.
Does the R5F101EDDNA#U0 include data flash memory?
No, the R5F101EDDNA#U0 does not include data flash memory. The '1' in the second digit of the part number (R5F101EDDNA#U0) explicitly denotes "data flash not provided", distinguishing it from R5F100x variants which integrate 4 KB or 8 KB data flash. Firmware must use code flash sectors for parameter storage.
What package type and dimensions does the R5F101EDDNA#U0 use?
The R5F101EDDNA#U0 uses a 40-pin HWQFN package measuring 6 mm × 6 mm with 0.5 mm pitch, per Renesas package code PWQN0040KC-A. It features an exposed thermal pad and complies with JEDEC MO-220 standards for surface-mount reflow assembly.
Can the R5F101EDDNA#U0 operate without an external crystal?
Yes, the R5F101EDDNA#U0 can operate using its on-chip high-accuracy oscillator (±1.0% over voltage and temperature), eliminating the need for external crystals in most timing-tolerant applications. External crystals remain supported via CLKP/CLKM pins for applications requiring tighter frequency stability.
How many analog input channels does the R5F101EDDNA#U0 support?
The R5F101EDDNA#U0 supports up to 26 analog input channels (ANI0 through ANI25), as confirmed in the RL78/G13 datasheet section 1.1 Features. These channels share the P20–P27 and P30–P37 port pins and are accessible simultaneously under DMA control for high-throughput sensor acquisition.
