Product details
Overview
R5F100GAANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 10-bit ADC (24 channels), real-time clock, UART/SPI/I²C interfaces, and operates from 1.6–5.5 V for battery-powered industrial sensors and smart meters.
For engineers reviewing the R5F100GAANA#U0 datasheet, R5F100GAANA#U0 pinout, R5F100GAANA#U0 application, or R5F100GAANA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm pitch package, industrial-grade -40°C to +105°C temperature rating (G suffix), integrated data flash with 1M rewrite cycles, and support for SNOOZE mode for low-latency peripheral wake-up without full CPU restart.
Technical Context
The R5F100GAANA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - enabling simultaneous program execution and nonvolatile data logging.
Peripheral integration includes dual DMA controllers (2/4 channels), 16-bit timer array (up to 16 channels), 12-bit interval timer, calendar-based RTC with alarm/correction, watchdog timer with dedicated low-speed oscillator, and hardware multiplier/divider/MAC unit for efficient signal processing in sensor fusion or motor control loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GAANA#U0 | No data flash (0 KB); identical core, peripherals, and package. | Not suitable for field-upgradable firmware or persistent parameter storage. | Select when code-only storage suffices and cost reduction is prioritized over nonvolatile data retention. |
| RA2A1GBMFP#AC0 | Arm Cortex-M23 core, 128 KB flash, 32 KB SRAM, 24-channel 12-bit ADC, same 48-pin QFN package. | Higher performance (64 MHz), TrustZone security, but lacks SNOOZE mode and has higher active current (120 μA/MHz). | Choose for applications requiring cryptographic acceleration or future-proof Arm ecosystem compatibility, accepting trade-offs in power and legacy toolchain support. |
Compared with R5F100GAANA#U0, R5F101GAANA#U0 removes data flash to lower cost and simplify programming, while RA2A1GBMFP#AC0 upgrades to Arm architecture with enhanced security and compute but increases power consumption and shifts toolchain requirements - making R5F100GAANA#U0 optimal for cost-sensitive, ultra-low-power industrial control where data logging and field updates are essential.

FAQ
What is the maximum operating temperature specification for the R5F100GAANA#U0?
The R5F100GAANA#U0 is rated for industrial operation from -40°C to +105°C, as indicated by the 'G' suffix in the part number. This rating applies across the full 1.6–5.5 V supply range and validates its use in enclosed environments like smart meters or motor drives where ambient heat buildup occurs. The device maintains specified timing, ADC accuracy, and flash endurance within this range.
Does the R5F100GAANA#U0 support in-system programming via its serial interfaces?
Yes, the R5F100GAANA#U0 supports in-system programming using the on-chip debug interface (single-wire SWD) and UART bootloader mode. The flash library enables self-programming of both code and data flash memory with boot swap functionality, allowing safe firmware updates without external programmers. No external high-voltage signals are required - programming occurs at standard VDD levels (1.8–5.5 V).
How many analog input channels does the R5F100GAANA#U0 support, and what is their resolution?
The R5F100GAANA#U0 integrates a 10-bit successive-approximation ADC with up to 24 configurable analog input channels. Channel mapping depends on pin assignment and port configuration; all channels share the same 10-bit resolution and support programmable sampling time. Internal 1.45 V reference and temperature sensor are accessible as dedicated analog inputs for calibration and environmental monitoring.
Can the R5F100GAANA#U0 operate from a single 3.3 V supply, and what are the implications for I/O voltage tolerance?
Yes, the R5F100GAANA#U0 operates fully across 1.6–5.5 V, including standard 3.3 V rails. Its I/O ports support different-potential interfacing: N-ch open-drain outputs tolerate up to 6 V, while TTL inputs accept thresholds compatible with 1.8 V, 2.5 V, and 3.0 V logic families. This allows direct connection to diverse peripherals without level shifters in mixed-voltage systems.
What low-power modes are available on the R5F100GAANA#U0, and which peripherals remain active in each?
The R5F100GAANA#U0 offers HALT (CPU stopped, peripherals active), STOP (all clocks halted except LSI for RTC/LVD), and SNOOZE (selected peripherals like UART/SPI/ADC run while CPU sleeps). In SNOOZE mode, configured serial interfaces can generate interrupts to wake the CPU within microseconds, preserving RAM and register contents - ideal for responsive sensor polling without full wake-up overhead.
