Product details
Overview
R5F104GAANA#W0 from Renesas Electronics is a 48-pin HWQFN-packaged 16-bit RL78/G14 microcontroller with 128 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C (industrial G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (16 channels), and real-time clock for embedded control in industrial sensing and motor drive systems.
For engineers reviewing the R5F104GAANA#W0 datasheet, R5F104GAANA#W0 pinout, R5F104GAANA#W0 application, or R5F104GAANA#W0 equivalent, key selection criteria include its industrial temperature rating (−40 to +105°C), 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) package with exposed die pad, integrated data flash rewrite capability (1M cycles), and hardware event linking via ELC for deterministic peripheral coordination.
Technical Context
The R5F104GAANA#W0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports multiply/divide/accumulate instructions and 1 MB address space with four register banks.
Its peripheral subsystem includes Event Link Controller (ELC) for direct hardware-triggered peripheral activation (19–26 event sources), Data Transfer Controller (DTC) with chain transfer, and dual-clock domain operation enabling simultaneous high-speed CPU execution and low-power RTC/LVD monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104GHANA#W0 | Same 48-pin HWQFN package, but 192 KB flash / 20 KB RAM / 8 KB data flash; identical peripherals and temperature grade | Required when application firmware exceeds 128 KB or needs >12 KB RAM for complex protocol stacks | Select R5F104GHANA#W0 if future firmware growth or additional buffer memory is anticipated; pinout and software are fully compatible. |
| R5F104GAAFB#30 | Same core, memory, and peripherals, but in 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) with different land pattern and no exposed pad | Suitable for legacy PCB designs using QFP footprints or where thermal dissipation via exposed pad is not required | Choose R5F104GAAFB#30 for compatibility with existing LFQFP layouts; note that thermal performance differs due to absence of exposed die pad. |
Compared with R5F104GHANA#W0, the R5F104GAANA#W0 trades flash/RAM headroom for cost optimization in fixed-function industrial controllers; compared with R5F104GAAFB#30, it offers superior thermal management and slightly higher I/O drive strength via the HWQFN package's exposed pad and shorter bond wires.

FAQ
What is the maximum operating temperature range for the R5F104GAANA#W0?
The R5F104GAANA#W0 is rated for industrial operation from −40°C to +105°C, as indicated by the 'G' suffix in the part number. This wide temperature range ensures reliable performance in demanding environments such as factory automation equipment, power supplies, and outdoor sensor enclosures where ambient heat buildup occurs.
Does the R5F104GAANA#W0 support in-system programming via standard interfaces?
Yes, the R5F104GAANA#W0 supports full in-system programming via SWD (Serial Wire Debug) using Renesas' E2 studio and Flash Development Toolkit. It also enables self-programming of both code and data flash memory with boot swap and flash shield window functions, allowing secure field firmware updates without external programmers.
How many analog input channels does the R5F104GAANA#W0 support, and what is the ADC resolution?
The R5F104GAANA#W0 integrates a 10-bit successive approximation ADC with up to 16 analog input channels (ANI0–ANI15), plus two dedicated VCOUT outputs. The ADC operates across the full 1.6–5.5 V supply range and includes an internal 1.45 V reference and integrated temperature sensor for system-level calibration.
What packaging and mounting details apply to the R5F104GAANA#W0?
The R5F104GAANA#W0 uses a 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch) with an exposed die pad. The '#W0' suffix denotes embossed tape packaging. Renesas recommends connecting the exposed pad directly to VSS for optimal thermal performance and noise immunity, and placing a 0.47–1 μF capacitor between REGC and VSS for regulator stability.
Can the R5F104GAANA#W0 operate from a single 1.8 V supply, and what features remain functional?
Yes, the R5F104GAANA#W0 supports operation from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, all core functions remain active: 32 MHz max frequency (via on-chip oscillator), 128 KB flash, 12 KB RAM, 10-bit ADC (with internal reference), RTC, and serial interfaces. However, some I/O drive strength and analog accuracy may be marginally reduced versus 3.3 V operation.
