Overview
R5F117BAGNA#20 from Renesas is a 32-pin, 16 KB flash, 2 KB data flash, 2 KB RAM RL78/I1D 16-bit microcontroller with ultra-low power consumption (58.3 μA/MHz active, 0.64 μA RTC+LVD standby), 24 MHz high-speed on-chip oscillator (±1.0% accuracy), and integrated 12-channel 12-bit A/D converter, 4 operational amplifiers, and 2 comparators - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F117BAGNA#20 datasheet, R5F117BAGNA#20 pinout, R5F117BAGNA#20 application, or R5F117BAGNA#20 equivalent, key selection criteria include its HVQFN-32 package, -40°C to +105°C industrial temperature grade, dual SPI/I²C interfaces, and hardware DTC/ELC for deterministic low-power peripheral coordination.
Technical Context
The R5F117BAGNA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 33 DMIPS @ 24 MHz, supporting multiply/divide/MAC instructions and 1 MB address space. Its clock system integrates selectable high-speed (24 MHz), middle-speed (4 MHz), and low-speed (15 kHz) on-chip oscillators plus external crystal support (X1/XT1).
Power management includes HALT, STOP, and SNOOZE modes, POR/LVD reset circuitry with 12-level voltage detection, and regulator-controlled VDD operation from 1.6 V to 3.6 V. Peripheral integration features a 4-channel 16-bit timer array, real-time clock with calendar/alarm, and background data flash rewriting (1M write cycles, 1.8–3.6 V).

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F117BAGNA#20?
The R5F117BAGNA#20 features a high-speed on-chip oscillator configurable up to 24 MHz with ±1.0% accuracy over -20°C to +85°C at 1.8–3.6 V supply. At extended temperatures (+85°C to +105°C), accuracy degrades to ±2.0% under 2.4–3.6 V conditions, as specified in the R01DS0244EJ0241 datasheet.
Does R5F117BAGNA#20 support background data flash rewriting while executing code from program memory?
Yes, the R5F117BAGNA#20 supports background operation (BGO) for data flash rewriting: instructions can be fetched and executed from code flash memory while simultaneously erasing or programming the 2 KB data flash area, enabling seamless firmware parameter updates without halting application logic.
How many analog input channels and operational amplifiers are integrated into R5F117BAGNA#20?
The R5F117BAGNA#20 integrates 12 analog input channels for its 12-bit A/D converter and four fully independent operational amplifiers (AMP0–AMP3), each with dedicated +, -, and output pins routed to specific port pins (e.g., P12/P13 for AMP0, P20–P22 for AMP3) as defined in the pin configuration diagram.
What package type and thermal characteristics define R5F117BAGNA#20?
R5F117BAGNA#20 uses a 32-pin HVQFN package (5 × 5 mm, 0.5 mm pitch) with an exposed die pad recommended for connection to VSS to enhance thermal dissipation. It is rated for industrial operation from -40°C to +105°C, with derating guidance provided for sustained operation above +85°C.
Can R5F117BAGNA#20 operate in ultra-low-power STOP mode while maintaining RTC and LVD functionality?
Yes, the R5F117BAGNA#20 achieves 0.64 μA typical current consumption in STOP mode with only the real-time clock (RTC2) and low-voltage detector (LVD) active - enabling decade-long battery life in maintenance-free sensor deployments while retaining timekeeping and brown-out monitoring capabilities.
