Product details
Overview
R5F100BCDNA#U0 from Renesas is a 32-pin RL78/G13 16-bit microcontroller with 32 KB flash memory, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V across -40°C to +85°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (26 channels), RTC, UART, I²C, SPI, and 16-bit timers for embedded control in smart sensors and industrial HMI.
For engineers reviewing the R5F100BCDNA#U0 datasheet, R5F100BCDNA#U0 pinout, R5F100BCDNA#U0 application, or R5F100BCDNA#U0 equivalent, key selection criteria include its HWQFN-32 package, integrated data flash with background operation (BGO), real-time clock with calendar/alarm, and support for low-voltage operation down to 1.6 V in space-constrained industrial nodes.
Technical Context
The R5F100BCDNA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 32 KB code flash (1 KB block size), 4 KB data flash with 1M rewrite cycles, and 2 KB on-chip RAM - all accessible under single-supply operation.
Peripheral integration targets deterministic real-time control: dual-channel DMA, 16-bit timer array (up to 16 channels), 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, and multi-protocol serial interfaces including UART/LIN, I²C, and CSI (SPI-compatible). Power management includes on-chip POR, LVD with 14-level interrupt/reset selection, and multiple low-power modes optimized for battery-backed applications.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100BCDNA#U0?
The R5F100BCDNA#U0 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS at that speed. Its RL78 CPU core supports configurable instruction timing, enabling operation from 32 MHz down to 32.768 kHz for ultra-low-power RTC functions - all within the same device without external clock sources.
Does the R5F100BCDNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100BCDNA#U0 supports full in-system programming via its on-chip debug interface and includes flash shield window and boot swap functions. These features enable secure, field-upgradable firmware with protected code regions - critical for industrial deployments where remote maintenance and security compliance are mandatory.
How many analog input channels does the R5F100BCDNA#U0 provide, and what ADC resolution is supported?
The R5F100BCDNA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), plus internal references (1.45 V) and a calibrated temperature sensor. This allows direct sensing of thermistors, potentiometers, and voltage rails without external signal conditioning in most industrial control applications.
What low-power modes are available on the R5F100BCDNA#U0, and which peripherals remain active in STOP mode?
The R5F100BCDNA#U0 offers HALT, STOP, and SNOOZE modes. In STOP mode, the RTC and LVD remain fully operational at just 0.57 μA - enabling wake-up on alarm, voltage threshold breach, or external interrupt while preserving calendar time and system safety monitoring without CPU intervention.
Is the R5F100BCDNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100BCDNA#U0 shares identical pinout and electrical characteristics with all other 32-pin HWQFN RL78/G13 devices (e.g., R5F100BDNA#U0, R5F101BCDNA#U0), enabling drop-in replacement within the same footprint. However, differences in flash size, data flash presence, and memory mapping require firmware validation before substitution.
