Product details
Overview
R5F101GGANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates 12-bit RTC, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and ultra-low-power STOP mode (0.57 μA) for battery-powered sensor nodes and industrial control units.
For engineers reviewing the R5F101GGANA#U0 datasheet, R5F101GGANA#U0 pinout, R5F101GGANA#U0 application, or R5F101GGANA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, absence of on-chip data flash, industrial-grade 105°C operation, and support for SNOOZE-mode peripheral wake-up without CPU intervention.
Technical Context
The R5F101GGANA#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 map spans 1 MB address space with banked 8-bit general-purpose registers and on-chip debug functionality.
Power management includes hardware HALT/STOP/SNOOZE modes, on-chip POR and 14-level LVD, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM. Peripheral integration covers up to 16× 16-bit timers, 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.

FAQ
What is the maximum clock frequency supported by the R5F101GGANA#U0?
The R5F101GGANA#U0 supports a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. This frequency is fully rated across the full -40°C to +105°C industrial temperature range and 1.6 V to 5.5 V supply voltage, enabling deterministic real-time control in motor drives and sensor fusion applications.
Does the R5F101GGANA#U0 include on-chip data flash memory?
No, the R5F101GGANA#U0 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number per Renesas documentation, this variant provides 96 KB of code flash and 8 KB of RAM but omits dedicated data flash. Applications requiring nonvolatile parameter storage must use external EEPROM or leverage code flash sectors with self-programming routines.
What package type and pin count does the R5F101GGANA#U0 use?
The R5F101GGANA#U0 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad. The "#U0" suffix confirms tray packaging for surface-mount assembly. This compact, thermally efficient package supports high-density PCB layouts while maintaining industrial-grade reliability and solder joint integrity.
Can the R5F101GGANA#U0 operate in extended temperature conditions?
Yes, the R5F101GGANA#U0 is rated for industrial operation from -40°C to +105°C, denoted by the "G" grade in its part number. This qualification includes full functionality of all peripherals - including 10-bit ADC, RTC, and serial interfaces - across the entire range, making it suitable for under-hood automotive, factory-floor, and outdoor infrastructure applications.
What low-power modes are available on the R5F101GGANA#U0?
The R5F101GGANA#U0 supports HALT, STOP, and SNOOZE modes. STOP mode draws just 0.57 μA while retaining RTC and LVD operation; HALT mode consumes 66 μA/MHz; SNOOZE allows selected peripherals (e.g., UART, ADC) to run autonomously while CPU remains halted. These modes are hardware-controlled and require no software polling, minimizing active power in always-on sensor nodes.
