Product details
Overview
R5F100ECANA#20 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (26 channels), real-time clock, UART/SPI/I²C interfaces, and DMA - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100ECANA#20 datasheet, R5F100ECANA#20 pinout, R5F100ECANA#20 application, or R5F100ECANA#20 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, integrated data flash with 1M rewrite cycles, STOP/HALT/SNOOZE low-power modes, and support for LIN-bus via UART - critical for cost-sensitive, energy-constrained embedded control designs.
Technical Context
The R5F100ECANA#20 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 subsystem clock). It includes on-chip power-on-reset, 14-level voltage detector, and background operation for data flash rewriting while executing code from program memory.
Its peripheral set includes up to 16-channel 16-bit timers, one 12-bit interval timer, calendar-based real-time clock with alarm and correction, watchdog timer with dedicated low-speed oscillator, and 3–10 channel I²C/Simplified I²C - all configurable via register-based control without external timing components.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100ECANA#20?
The R5F100ECANA#20 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. Its minimum instruction execution time is 0.03125 μs under this condition, enabling responsive real-time control in applications such as motor commutation and sensor fusion where deterministic timing is critical. The R5F100ECANA#20 maintains this performance across its full 1.6 V to 5.5 V supply range.
Does the R5F100ECANA#20 support LIN bus communication, and how is it implemented?
Yes, the R5F100ECANA#20 supports LIN bus communication through its UART peripheral, which includes built-in LIN-break detection and sync-field generation. This capability is enabled in UART mode with specific register configuration and does not require external transceivers for basic node functionality. The R5F100ECANA#20's UART/LIN module is fully integrated and shares pins with standard serial interfaces, allowing flexible routing in space-constrained layouts.
What low-power modes are available on the R5F100ECANA#20, and what is the lowest achievable current draw?
The R5F100ECANA#20 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables decade-long battery operation in wireless sensor nodes. The R5F100ECANA#20 exits STOP mode in under 4 μs upon RTC alarm or external interrupt, ensuring rapid responsiveness.
Can the R5F100ECANA#20 perform flash self-programming, and what safeguards are included?
Yes, the R5F100ECANA#20 supports full flash self-programming including both code and data flash, with boot swap functionality and flash shield window protection. These features prevent unauthorized access to firmware during field updates and allow safe dual-bank operation. The R5F100ECANA#20 uses on-chip RAM areas (e.g., FEF00H start address) for flash library execution, eliminating external RAM dependency during reprogramming sequences.
What is the ADC resolution, channel count, and reference voltage option on the R5F100ECANA#20?
The R5F100ECANA#20 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference voltages or the internal 1.45 V reference, selectable per conversion group. The ADC operates across the full 1.6 V to 5.5 V supply range and includes sample-and-hold circuitry, making it suitable for precision ratiometric measurements in industrial and medical sensor interfaces. The R5F100ECANA#20 also includes an on-chip temperature sensor accessible via dedicated ADC channel.
