Product details
Overview
R5F100BEANA#20 from Renesas is a 32-bit RL78/G13 microcontroller featuring 64 KB flash memory, 4 KB data flash, 4 KB RAM, 32-pin HWQFN (5 × 5 mm, 0.5-mm pitch) package, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), deployed in battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F100BEANA#20 datasheet, R5F100BEANA#20 pinout, R5F100BEANA#20 application, or R5F100BEANA#20 equivalent, key selection criteria include its integrated 10-bit ADC (26-channel), real-time clock with calendar/alarm, LIN-capable UART, and support for SNOOZE mode wake-up via peripheral interrupts - all within a -40°C to +85°C industrial temperature grade.
Technical Context
The R5F100BEANA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz high-speed oscillator or 30.5 μs @ 32.768 kHz subsystem clock). It supports background data flash rewriting (BGO) and self-programming with boot swap and flash shield window functions.
Power management includes HALT, STOP, and SNOOZE modes; on-chip LVD offers 14 selectable voltage detection levels with interrupt/reset options; DMA controller provides 2 channels with 2-clock transfers between SFR and RAM; and the 16×16-bit multiplier/32-bit divider enables efficient signal processing in resource-constrained edge devices.

Yes, the R5F100BEANA#20 integrates a full-featured RTC with calendar support (99-year range), alarm function, and clock correction capability. It operates independently in STOP mode using the 32.768 kHz subsystem clock, consuming only 0.57 μA - a key enabler for time-stamped logging in battery-powered applications.
How many analog input channels does the R5F100BEANA#20 support?
The R5F100BEANA#20 supports 26 analog input channels for its 10-bit ADC, including dedicated pins like P20/ANI0, P21/ANI1, P22/ANI2, and extended channels such as P147/ANI18. All channels operate across the full 1.6–5.5 V supply range and support internal 1.45 V reference and temperature sensor measurement.
Is the R5F100BEANA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100BEANA#20 shares identical pinout and electrical characteristics with all 32-pin HWQFN RL78/G13 variants (e.g., R5F100BAANA#20, R5F100BCANA#20), enabling drop-in replacement within the same memory/feature tier. Pin compatibility is guaranteed per Renesas Package Outline PWQN0032KB-A and PWQN0032KE-A specifications.
What debug and programming interfaces are supported by the R5F100BEANA#20?
The R5F100BEANA#20 supports on-chip debugging via the single-wire debug interface (SWD) using the TOOLRxD/TOOLTxD pins (P11/P12), compatible with Renesas E2 emulator and CS+ IDE.
