Product details
Overview
R5F101ECDNA#U0 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 2 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F101ECDNA#U0 datasheet, R5F101ECDNA#U0 pinout, R5F101ECDNA#U0 application, or R5F101ECDNA#U0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, absence of on-chip data flash (confirmed by "101" in part number), -40°C to +85°C industrial temperature grade (D suffix), and integrated 10-bit ADC with 26-channel analog input capability.
Technical Context
The R5F101ECDNA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, watchdog timer, and DMA controller with 2 channels.
Peripheral integration includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, and 2–8-channel CSI (SPI-compatible serial interface), all operating across the full 1.6–5.5 V supply range and qualified for industrial ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time control with low gate count and power efficiency. |
| Max Operating Frequency | 32 MHz (41 DMIPS); delivers sufficient throughput for sensor fusion and protocol stack handling in compact edge devices. |
| Memory Configuration | 64 KB code flash / 0 KB data flash / 2 KB RAM; "101" prefix confirms no embedded data flash - external EEPROM or FRAM required for nonvolatile parameter storage. |
| Power Consumption | 66 μA/MHz active current; 0.57 μA in STOP mode with RTC + LVD active - enables >10-year battery life in periodic wake-up sensing applications. |
| Analog Peripherals | 10-bit ADC with 26 input channels, internal 1.45 V reference, and on-chip temperature sensor - supports multi-sensor monitoring without external references. |
| Operating Voltage & Temp | 1.6 V to 5.5 V supply; -40°C to +85°C industrial grade (D suffix); suitable for unregulated battery or wide-input industrial power rails. |
| Package & Pin Count | HWQFN-40, 6 × 6 mm, 0.5 mm pitch (PWQN0040KC-A); surface-mount compatible with automated assembly and thermal performance suited for enclosed enclosures. |
Pinout & Package
Package: HWQFN-40, 6 × 6 mm body, 0.5 mm pitch, exposed thermal pad (PWQN0040KC-A). Pinout conforms to RL78/G13 40-pin standard layout; pin functions are multiplexed across I/O, analog, serial, timer, and system control resources.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10/SCK00/SCL00 | SPI clock / I²C clock | Shared hardware resource enabling dual-mode serial peripheral interface - reduces pin count while supporting both protocols via software configuration. |
| P11/SI00/RxD0/TOOLRxD/SDA00 | SPI input / UART receive / I²C data | Tri-function pin supports debug communication (TOOLRxD), host interface (RxD0), and sensor bus (SDA00) - simplifies board routing in space-constrained designs. |
| P20/ANI0/AVREFP | Analog input 0 / ADC reference positive | Enables flexible ADC reference sourcing: AVREFP can be tied to external reference or VDD, allowing ratiometric or absolute voltage measurements. |
| P21/ANI1/AVREFM | Analog input 1 / ADC reference negative | Paired with P20 to define differential ADC reference window; supports true differential analog acquisition or ground-referenced single-ended measurement. |
| P30/INTP0/TOOLTXD | External interrupt 0 / debug transmit | Dual-role pin allows wake-up from STOP mode via external event while simultaneously supporting on-chip debugging without dedicated SWD/JTAG pins. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power STOP mode | 0.57 μA with RTC + LVD active - enables decade-scale battery operation in wireless sensor endpoints with daily wake-up intervals. |
| Self-programmable flash | Boot swap and flash shield window support secure firmware updates without external programmer; requires external RAM allocation per flash library spec. |
| Hardware-accelerated math | 16×16→32-bit multiply, 32÷32→32-bit divide, and MAC units reduce firmware overhead in control loop and signal processing tasks. |
| Multiprotocol serial interface | CSI (SPI), UART/LIN, and I²C share common hardware blocks - minimizes silicon area and simplifies PCB layout for mixed-interface systems. |
| On-chip voltage detector | 14-level LVD with selectable interrupt/reset behavior - provides robust brown-out protection across varying battery discharge curves. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100ECDNA#U0 | Includes 4 KB data flash; identical pinout, package, and peripherals; same 64 KB code flash and 2 KB RAM. | Preferred where firmware must store calibration data or field-upgrade parameters without external memory. | Select when nonvolatile parameter storage is required - adds ~$0.15 BOM cost but eliminates external EEPROM footprint and firmware complexity. |
| R5F101ECDFB#V0 | LQFP-44 package (10 × 10 mm, 0.65 mm pitch); same memory, peripherals, and electrical specs; +4 I/O pins. | Better suited for prototyping or designs requiring manual soldering or test probe access due to larger pitch and exposed leads. | Choose for development boards or low-volume production where hand-soldering or ICT testing is needed; not drop-in compatible due to package and pin count difference. |
Compared with R5F101ECDNA#U0, R5F100ECDNA#U0 adds data flash for embedded parameter storage without changing layout or firmware porting effort, while R5F101ECDFB#V0 trades miniaturization for assembly flexibility and extra I/O - making each alternative optimal for distinct design priorities: data persistence, manufacturability, or I/O headroom.

FAQ
What is the flash memory configuration of the R5F101ECDNA#U0?
The R5F101ECDNA#U0 contains 64 KB of on-chip code flash memory and 2 KB of RAM. Critically, it has no embedded data flash - the "101" in the part number explicitly denotes zero data flash capacity, unlike "100" variants which include 4 KB. This requires external nonvolatile storage if runtime parameter retention is needed.
Does the R5F101ECDNA#U0 support hardware debugging?
Yes, the R5F101ECDNA#U0 supports on-chip debugging via dedicated TOOLRxD and TOOLTXD pins (P11 and P30), enabling full SWD-style programming and real-time trace without external debug probes. The debug interface operates concurrently with application I/O functions, preserving pin count in production firmware.
What is the maximum ADC channel count supported by the R5F101ECDNA#U0?
The R5F101ECDNA#U0 supports up to 26 analog input channels for its 10-bit successive-approximation ADC. Channel mapping is fixed per pin assignment in the 40-pin HWQFN package, including dedicated ANI0–ANI2 pins and additional analog-capable GPIOs such as P147/ANI18, confirmed in the RL78/G13 pin configuration tables.
Is the R5F101ECDNA#U0 qualified for industrial temperature operation?
Yes, the "D" suffix in R5F101ECDNA#U0 specifies industrial temperature grade with guaranteed operation from -40°C to +85°C. This qualification covers all electrical specifications including flash write endurance, ADC accuracy, and oscillator stability - validated across the full range per Renesas specification R01DS0131EJ0380.
What package type and dimensions does the R5F101ECDNA#U0 use?
The R5F101ECDNA#U0 uses a 40-pin HWQFN package (Renesas code PWQN0040KC-A), measuring 6 mm × 6 mm with 0.5 mm pitch and an exposed thermal pad. This package supports high-density PCB layouts and provides superior thermal performance versus TSSOP alternatives, with reflow profile compatibility per JEDEC J-STD-020.
