FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104EDGNA#W0?
The R5F104EDGNA#W0 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. At full speed, this yields ~2.1 mA total active current. Its ultra-low-power STOP mode draws only 0.60 μA while retaining RTC and LVD functionality - critical for battery longevity in always-on applications. The high-accuracy ±1.0% on-chip oscillator eliminates need for external crystal in many use cases.
Does the R5F104EDGNA#W0 support in-system programming and secure firmware updates?
Yes, the R5F104EDGNA#W0 supports full in-system programming via its on-chip debug interface and UART bootloader. It includes boot swap functionality and flash shield window protection to prevent unauthorized access to critical firmware sections. Self-programming allows rewrites of both code and data flash while executing from other memory regions, enabling robust over-the-air (OTA) update mechanisms without requiring external programmers.
How many analog input channels and what ADC resolution does the R5F104EDGNA#W0 provide?
The R5F104EDGNA#W0 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), including dedicated AVREFP/AVREFM pins for precise ratiometric measurements. It also features an internal 1.45 V reference voltage and on-die temperature sensor - eliminating external components for basic environmental monitoring and sensor calibration tasks in the R5F104EDGNA#W0 design.
What serial communication interfaces are available on the R5F104EDGNA#W0?
The R5F104EDGNA#W0 provides three UART/LIN channels, four to ten I²C interfaces (configurable as simplified I²C), and three to eight CSI (SPI-compatible) channels. All are multiplexed across GPIO pins with flexible peripheral I/O redirection registers (PIOR0/1), allowing dynamic assignment without PCB redesign. LIN compliance enables direct connection to automotive body electronics networks without external transceivers in the R5F104EDGNA#W0 implementation.
Is the R5F104EDGNA#W0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 40-pin HWQFN package - including R5F104EDGNA#W0, R5F104EEGNA#W0, and R5F104FDGNA#W0 - share identical pinouts, electrical characteristics, and thermal profiles. This allows direct substitution based on flash/RAM requirements without layout changes. The G-grade (-40 to +105°C) qualification and #W0 embossed tape packaging ensure consistent manufacturability and industrial reliability for the R5F104EDGNA#W0 and its family members.
