Product details
Overview
R5F101BEANA#20 from Renesas is a 32-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM in a 32-pin HWQFN (5 × 5 mm, 0.5-mm pitch) package, 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), RTC, UART/SPI/I²C interfaces, and hardware DMA - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101BEANA#20 datasheet, R5F101BEANA#20 pinout, R5F101BEANA#20 application, or R5F101BEANA#20 equivalent, key selection criteria include verified low-power operation down to 0.57 μA in STOP mode with RTC/LVD active, confirmed 32-pin HWQFN-NA package compatibility, validated 10-bit ADC channel count (26 inputs), and documented support for background data flash rewriting (BGO) at VDD = 1.8–5.5 V.
Technical Context
The R5F101BEANA#20 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 integrates a 16-bit timer array (16 channels), real-time clock with calendar/alarm/correction, and watchdog timer driven by dedicated low-speed oscillator.
Its peripheral set includes UART/UART (LIN-capable), simplified SPI (CSI), I²C/Simplified I²C (up to 10 channels), 10-bit A/D converter with internal reference (1.45 V) and temperature sensor, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

FAQ
What is the operating voltage range for the R5F101BEANA#20?
The R5F101BEANA#20 operates from 1.6 V to 5.5 V across its full temperature range (-40°C to +85°C). This wide supply range supports direct connection to single-cell Li-ion, 3× alkaline, or regulated 3.3 V/5 V rails without external level-shifting, simplifying power architecture in portable and industrial designs.
Does the R5F101BEANA#20 include an integrated temperature sensor?
Yes, the R5F101BEANA#20 includes an on-die temperature sensor usable via the 10-bit ADC. It is factory-calibrated and accessible through dedicated ANI channel(s); typical accuracy is ±2°C over the industrial temperature range, enabling thermal monitoring without external components.
What debug interface does the R5F101BEANA#20 support?
The R5F101BEANA#20 supports on-chip debugging via the single-wire debug (SWD) interface using the TOOLx pins (e.g., TOOLRxD on P11). It is compatible with Renesas E2 emulator and third-party tools supporting SWD, enabling full breakpoint, watchpoint, and flash programming capabilities.
Can the R5F101BEANA#20 perform flash self-programming while executing code?
Yes, the R5F101BEANA#20 supports self-programming of both code and data flash memory. The data flash supports background operation (BGO), allowing instruction execution from program memory during data flash rewrite - critical for zero-downtime firmware updates in field-deployed devices.
Is the R5F101BEANA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 32-pin HWQFN-NA package (e.g., R5F101BAANA#20, R5F101BFANA#20) share identical pinouts and electrical characteristics. This allows drop-in replacement across memory variants without PCB redesign, provided software accommodates differing flash/RAM sizes.
