Product details
Overview
R5F101BGANA#U0 from Renesas is a 32-pin VFBGA-packaged RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101BGANA#U0 datasheet, R5F101BGANA#U0 pinout, R5F101BGANA#U0 application, or R5F101BGANA#U0 equivalent, key selection criteria include its VFBGA-32 package (0.4 mm pitch), absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade, and support for SNOOZE mode wake-up via peripheral interrupts.
Technical Context
The R5F101BGANA#U0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, plus dual 16-bit timer arrays and one 12-bit interval timer.
Its power architecture includes HALT, STOP, and SNOOZE modes, with dedicated low-speed on-chip oscillator for watchdog and RTC operation. The device supports background operation (BGO) for flash programming only in R5F100x variants - not applicable to R5F101BGANA#U0 due to lack of data flash memory.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100BGANA#U0 | Same 32-pin VFBGA package and pinout; includes 8 KB data flash and BGO support | Required where field firmware updates or parameter storage in data flash is needed | Select when nonvolatile parameter retention or background flash reprogramming is mandatory |
| R5F101BGAFP#V0 | LQFP-32 package (7×7 mm, 0.5 mm pitch); identical memory and peripheral set | Better suited for prototyping, manual soldering, or legacy board designs using QFP footprints | Choose for ease of assembly, test access, or compatibility with existing LQFP layouts |
Compared with R5F101BGANA#U0, R5F100BGANA#U0 adds data flash for runtime configuration storage but increases cost and power in STOP mode; R5F101BGAFP#V0 trades the compact VFBGA for LQFP's mechanical robustness and debug accessibility - critical for development-phase validation.

FAQ
Does R5F101BGANA#U0 include on-chip data flash memory?
No, R5F101BGANA#U0 belongs to the R5F101x series, which omits data flash memory entirely. This distinguishes it from the R5F100x series (e.g., R5F100BGANA#U0), which includes 8 KB of data flash with background operation (BGO) support. Applications requiring nonvolatile parameter storage must use an R5F100x variant or external EEPROM.
What is the operating temperature range for R5F101BGANA#U0?
R5F101BGANA#U0 is rated for industrial operation from –40°C to +85°C. The "A" suffix in the part number denotes this temperature grade; it is not qualified for the extended –40°C to +105°C range (G-grade) offered by some R5F100x variants in the same RL78/G13 family.
Which package type does R5F101BGANA#U0 use, and what are its key mechanical features?
R5F101BGANA#U0 uses a 32-pin VFBGA package (4 mm × 4 mm, 0.4 mm pitch) with solder-ball terminations. Its compact footprint and fine-pitch design support high-density PCB layouts, while the #U0 suffix indicates tray packaging for automated SMT placement. MSL3 rating requires bake-before-reflow per J-STD-020.
Can R5F101BGANA#U0 operate from a single 1.8 V supply?
Yes, R5F101BGANA#U0 supports 1.6 V to 5.5 V single-supply operation. At 1.8 V, it can run up to 16 MHz (per datasheet DC characteristics), enabling ultra-low-power operation in energy-harvesting or coin-cell applications - though maximum 32 MHz performance requires ≥2.7 V.
How many analog input channels does the 10-bit ADC in R5F101BGANA#U0 support?
The R5F101BGANA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), configurable via the ANIS register. Input channels include dedicated pins (e.g., P20/ANI0, P21/ANI1) and multiplexed I/O functions - all referenced to internal 1.45 V or external AVREFP/AVREFM.
