Product details
Overview
R5F100BCANA#40 from Renesas is a 32-pin, 16-bit RL78/G13 microcontroller with 16 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. It delivers 41 DMIPS at 32 MHz, features ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (6 channels), RTC, UART, I²C, and SPI for embedded control in battery-powered industrial sensors and smart home peripherals.
For engineers reviewing the R5F100BCANA#40 datasheet, R5F100BCANA#40 pinout, R5F100BCANA#40 application, or R5F100BCANA#40 equivalent, key selection criteria include its HWQFN-32 package, integrated data flash with background operation, low-voltage operation down to 1.6 V, and support for SNOOZE mode wake-up via serial interface-critical for energy-constrained edge nodes.
Technical Context
The R5F100BCANA#40 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory architecture includes separate code flash (16 KB), data flash (4 KB), and RAM (2 KB), with self-programming capability and boot swap function enabled by on-chip debug support.
Peripheral integration includes an 8-channel 16-bit timer, 1-channel 12-bit interval timer, 1-channel real-time clock with calendar and alarm, and dual UART/LIN interfaces-all configurable via dedicated SFRs. Power management includes HALT, STOP, and SNOOZE modes, with LVD interrupt/reset selectable across 14 voltage levels and POR circuitry for reliable startup.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100BCANA#40?
The R5F100BCANA#40 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS at that speed. This performance level is confirmed in the official Renesas datasheet R01DS0131EJ0380 and enables efficient execution of real-time control algorithms and communication stacks without external acceleration.
Does the R5F100BCANA#40 include integrated data flash memory, and what is its endurance specification?
Yes, the R5F100BCANA#40 includes 4 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. This memory supports background operation (BGO), allowing program execution from code flash during data flash rewrites-a key enabler for robust firmware updates and parameter logging.
What package type and pin count does the R5F100BCANA#40 use, and is thermal pad soldering required?
The R5F100BCANA#40 uses a 32-pin HWQFN package (5 × 5 mm, 0.5-mm pitch) with an exposed thermal pad on the underside. Renesas design guidelines require soldering this pad to a solid copper thermal plane on the PCB to ensure proper thermal dissipation and electrical grounding-omitting it risks overheating and signal integrity issues.
Can the R5F100BCANA#40 operate from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F100BCANA#40 supports operation from 1.6 V to 5.5 V, so 1.8 V is fully within specification. At 1.8 V, all core functions-including 10-bit ADC (with internal 1.45 V reference), RTC, UART, I²C, SPI, timers, and GPIO-remain fully operational, enabling direct compatibility with 1.8 V logic families and low-voltage battery systems.
How many analog input channels does the R5F100BCANA#40 support, and are internal reference and temperature sensing available?
The R5F100BCANA#40 supports 6 analog input channels (ANI0–ANI5) with 10-bit resolution. It includes an internal 1.45 V reference voltage source and a calibrated temperature sensor-both accessible via dedicated ADC channels and usable across the full operating voltage and temperature range without external components.
