Overview
R5F100BEGNA#20 from Renesas is a 32-pin, 16-bit RL78/G13 microcontroller with 64 KB flash memory, 4 KB data flash, and 4 KB RAM, operating at up to 32 MHz with 41 DMIPS performance. It features ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), integrated 10-bit ADC (26-channel), real-time clock, and multiple serial interfaces (UART, I²C, CSI) for embedded control in battery-powered industrial sensors and smart home devices.
For engineers reviewing the R5F100BEGNA#20 datasheet, R5F100BEGNA#20 pinout, R5F100BEGNA#20 application, or R5F100BEGNA#20 equivalent, key selection criteria include its HWQFN-32 package, -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, self-programmable flash with boot swap, and BGO-capable data flash for concurrent execution and rewriting.
Technical Context
The R5F100BEGNA#20 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory subsystem includes 64 KB code flash (1 KB block size), 4 KB data flash with background operation (BGO), and 4 KB SRAM - all accessible under single 1.6–5.5 V supply.
Peripherals include eight 16-bit timers, one 12-bit interval timer, one calendar RTC with alarm and correction, one watchdog timer, two DMA channels, and a 10-bit A/D converter with internal reference voltage (1.45 V) and temperature sensor. Serial connectivity comprises up to four UART/LIN channels, ten I²C/Simplified I²C channels, and eight CSI (SPI-compatible) channels.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100BEGNA#20?
The R5F100BEGNA#20 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This is achieved using the on-chip high-speed oscillator (±1.0% accuracy) without requiring an external crystal, making it suitable for time-critical control loops in motor drives and sensor fusion applications. The RL78 core's 3-stage pipeline ensures consistent instruction timing across voltage and temperature ranges.
Does the R5F100BEGNA#20 support in-system programming and secure firmware updates?
Yes, the R5F100BEGNA#20 supports full in-system programming via its on-chip debug interface and includes flash shield window functionality to restrict read/write access to designated memory regions. It also implements boot swap capability, allowing validated firmware images to be loaded into a secondary bank and atomically activated - preventing bricking during power failure or interrupted updates.
What analog capabilities does the R5F100BEGNA#20 provide for sensor interfacing?
The R5F100BEGNA#20 integrates a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-die temperature sensor. These features enable direct connection of thermistors, RTDs, and other analog sensors without external precision references or signal conditioning, reducing BOM cost and PCB area in environmental monitoring designs.
How does the R5F100BEGNA#20 manage power in battery-operated applications?
The R5F100BEGNA#20 achieves ultra-low power operation with 66 μA/MHz active current and 0.57 μA in STOP mode with RTC and LVD enabled. Its SNOOZE mode allows selected peripherals (e.g., UART or ADC) to remain active while the CPU sleeps, enabling event-driven wake-up with sub-4 μs latency - ideal for intermittent sensing in wireless sensor nodes powered by coin cells or energy harvesters.
Is the R5F100BEGNA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100BEGNA#20 shares identical pinout and electrical characteristics with all other 32-pin HWQFN RL78/G13 devices (e.g., R5F100BGxxx, R5F101BGxxx), including identical I/O mapping, power pin locations, and reset configuration. This enables hardware reuse across memory and feature variants, simplifying design scalability and migration paths within the RL78/G13 family.
