Product details
Overview
R5F100BEGNA#U0 from Renesas is a 32-pin RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces (UART, I²C, CSI) for embedded control in industrial and consumer applications.
For engineers reviewing the R5F100BEGNA#U0 datasheet, R5F100BEGNA#U0 pinout, R5F100BEGNA#U0 application, or R5F100BEGNA#U0 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 BGO, and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F100BEGNA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), DMA controller (4 channels), 16-bit timer array (12 channels), and hardware multiplier/divider.
Power management includes HALT, STOP, and SNOOZE low-power modes, on-chip POR and LVD (14-level selectable), and voltage operation from 1.6 V to 5.5 V. Its peripheral set targets cost-sensitive, power-constrained general-purpose control-especially where mixed-signal integration, code security (flash block protection), and background data flash rewriting are required.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100BEGNA#U0?
The R5F100BEGNA#U0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time - enabling adaptive power/performance tuning in the R5F100BEGNA#U0 design.
Does the R5F100BEGNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100BEGNA#U0 supports full in-system programming via its on-chip debug interface and boot swap function. It includes flash shield window and block erase prohibition features to prevent unauthorized rewriting of protected code sections. The R5F100BEGNA#U0 also enables background operation during data flash updates, allowing uninterrupted program execution - essential for field-upgradable R5F100BEGNA#U0 deployments.
What analog capabilities does the R5F100BEGNA#U0 provide for sensor interfacing?
The R5F100BEGNA#U0 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 allow direct connection of thermistors, potentiometers, and other analog sensors without external references or signal conditioning. All analog functions are fully supported in the R5F100BEGNA#U0's industrial temperature range (-40°C to +105°C).
How does the R5F100BEGNA#U0 manage power in battery-powered applications?
The R5F100BEGNA#U0 achieves industry-leading low-power operation: 66 μA/MHz in active mode, 0.57 μA in STOP mode with RTC and LVD enabled, and configurable HALT/SNOOZE modes. Its wide 1.6–5.5 V supply range accommodates declining battery voltages, and the on-chip LVD provides programmable reset/interrupt thresholds to safeguard operation during brownout - making the R5F100BEGNA#U0 ideal for long-life battery systems.
Is the R5F100BEGNA#U0 pin-compatible with other RL78/G13 devices in the same package?
Yes, all RL78/G13 devices in the HWQFN-32 package (e.g., R5F100BA–R5F100BG, R5F101BA–R5F101BG) share identical pinouts and electrical characteristics. This allows direct substitution within the same memory/feature tier - for example, upgrading from R5F100BDGNA#U0 to R5F100BEGNA#U0 requires no PCB change, only firmware update to leverage the additional 32 KB flash and full data flash functionality in the R5F100BEGNA#U0.
