Overview
R5F104GEANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G14 microcontroller with 48 KB flash, 5.5 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (44 DMIPS). It integrates 10-bit ADC (12 channels), UART/SPI/I²C interfaces, RTC, low-power STOP/HALT modes (0.60 μA), and is qualified for industrial applications (−40°C to +105°C).
For engineers reviewing the R5F104GEANA#U0 datasheet, R5F104GEANA#U0 pinout, R5F104GEANA#U0 application, or R5F104GEANA#U0 equivalent, key selection criteria include its 48-pin 7×7 mm HWQFN package, 48 KB code flash with self-programming, integrated 10-bit ADC and serial peripherals, and industrial-temperature operation with ultra-low standby current.
Technical Context
The R5F104GEANA#U0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and includes multiply/divide/accumulate instructions. Its memory subsystem comprises 48 KB on-chip flash (1 KB block size), 5.5 KB RAM, and 4 KB data flash with background operation and 1M rewrite cycles.
Peripheral integration includes an Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) for interrupt-driven DMA, and configurable I/O with N-ch open-drain capability, TTL input buffers, and on-chip pull-up resistors-enabling direct interfacing with 1.8/2.5/3.0 V logic.

Does the R5F104GEANA#U0 support in-system programming and secure firmware updates?
Yes, the R5F104GEANA#U0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for secure firmware updates. It also implements boot swap functionality, allowing validated firmware images to be loaded into inactive flash banks and activated atomically-ensuring zero-downtime updates in deployed R5F104GEANA#U0 systems.
How many analog input channels and what ADC resolution does the R5F104GEANA#U0 provide?
The R5F104GEANA#U0 integrates a 10-bit successive-approximation ADC with up to 12 configurable analog input channels (ANI0–ANI7 plus additional multiplexed pins). It includes internal reference voltage (1.45 V) and a calibrated temperature sensor, enabling accurate voltage, current, and thermal monitoring without external components in R5F104GEANA#U0-based designs.
What low-power modes are available on the R5F104GEANA#U0, and what is the lowest achievable current consumption?
The R5F104GEANA#U0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.60 μA (typical) at VDD = 3.0 V and TA = 25°C. This ultra-low current enables multi-year operation on coin-cell batteries in R5F104GEANA#U0-based metering and sensor nodes, with wake-up via RTC alarm or external interrupt.
Is the R5F104GEANA#U0 pin-compatible with other RL78/G14 variants in the same package?
