Overview
R5F100BDGNA#20 from Renesas is a 32-pin, 32 MHz RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, ultra-low power operation (66 μA/MHz active, 0.57 μA RTC+LVD), and industrial-grade −40°C to +105°C temperature range. It integrates 16-bit timer, 10-bit ADC (12 channels), UART/SPI/I²C interfaces, and real-time clock for embedded control in HVAC, motor drives, and smart sensors.
For engineers reviewing the R5F100BDGNA#20 datasheet, R5F100BDGNA#20 pinout, R5F100BDGNA#20 application, or R5F100BDGNA#20 equivalent, key selection criteria include its HWQFN-32 package, G-grade temperature rating, integrated data flash with 1M rewrite cycles, low-power STOP/HALT modes, and RL78 CPU core delivering 41 DMIPS at 32 MHz.
Technical Context
The R5F100BDGNA#20 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It features on-chip high-accuracy ±1.0% oscillator (1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its memory subsystem includes 64 KB code flash (1 KB block size, security lock), 4 KB data flash with background operation (BGO) and 1,000,000 write endurance, and 4 KB SRAM. Power management includes POR, LVD (14-level selectable), and multiple low-power modes-HALT, STOP, and SNOOZE-with fast wake-up from STOP in under 4 μs.

FAQ
What is the operating temperature range of the R5F100BDGNA#20?
The R5F100BDGNA#20 is rated for industrial operation from −40°C to +105°C (G-grade), making it suitable for deployment in enclosed motor drives, outdoor energy meters, and HVAC systems where ambient temperatures exceed standard consumer-grade limits. This rating is validated per Renesas specification R01DS0131EJ0380.
Does the R5F100BDGNA#20 include on-chip debug functionality?
Yes, the R5F100BDGNA#20 includes full on-chip debug support via the single-wire debug interface (SWD), compatible with Renesas E2 studio and CS+ IDEs. This enables non-intrusive breakpoints, real-time variable watch, and flash programming without requiring additional debug hardware beyond a standard J-Link or E2 Lite emulator.
What is the maximum ADC resolution and channel count supported by the R5F100BDGNA#20?
The R5F100BDGNA#20 integrates a 10-bit successive approximation ADC with up to 12 analog input channels (ANI0–ANI11), internal 1.45 V reference, and temperature sensor. It operates across the full 1.6–5.5 V supply range, enabling accurate voltage, current, and thermal measurements in battery-powered and wide-input applications.
Can the R5F100BDGNA#20 operate from a single 3.3 V supply?
Yes, the R5F100BDGNA#20 supports 1.6 V to 5.5 V single-supply operation, including standard 3.3 V rails. All I/Os are 5 V-tolerant on designated pins (e.g., P00–P03), and the internal voltage regulator ensures stable core operation across this range without external LDOs or level shifters.
How many UART, SPI, and I²C interfaces does the R5F100BDGNA#20 provide?
The R5F100BDGNA#20 provides 2 UART channels (with LIN bus support), 2 CSI channels (functionally equivalent to SPI), and 3 I²C/Simplified I²C channels. These are multiplexed across dedicated pins and support simultaneous operation, enabling concurrent communication with displays, sensors, and wireless modules.
