Product details
Overview
R5F101BCANA#40 from Renesas is a 16-bit RL78/G13 microcontroller with no data flash, 16 KB code flash, 2 KB RAM, and 36-pin HWQFN (4 × 4 mm, 0.5-mm pitch) package, 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 consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), and integrates 10-bit ADC (6 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101BCANA#40 datasheet, R5F101BCANA#40 pinout, R5F101BCANA#40 application, or R5F101BCANA#40 equivalent, key selection criteria include its 36-pin HWQFN footprint, absence of on-chip data flash, 16 KB/2 KB memory configuration, support for STOP/HALT/SNOOZE low-power modes, and compatibility with Renesas' RL78 toolchain and CS+ IDE.
Technical Context
The R5F101BCANA#40 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It supports single-supply operation (1.6–5.5 V), includes an on-chip high-accuracy ±1.0% oscillator (32 MHz max), and integrates dedicated peripherals including 1-channel real-time clock with calendar/alarm functions and 1-channel watchdog timer.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN-capable serial interfaces, and 2× CSI (SPI-compatible) channels - all accessible via configurable GPIO with N-ch open-drain, TTL input, and pull-up options. The device lacks data flash but retains full self-programming capability for code flash using boot swap and flash shield window functions.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for R5F101BCANA#40?
The R5F101BCANA#40 operates at up to 32 MHz using its on-chip high-speed oscillator and achieves 41 DMIPS (Dhrystone MIPS) at that frequency. This performance level is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80) and reflects sustained integer compute throughput under typical operating conditions with cache disabled and optimized compiler settings.
Does R5F101BCANA#40 include on-chip data flash memory?
No, R5F101BCANA#40 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number per Renesas' naming convention, this variant provides 16 KB of code flash and 2 KB of RAM but omits the 4 KB data flash found in "100" series counterparts like R5F100BCANA#40. Firmware must manage non-volatile storage externally or via code flash emulation.
What package type and dimensions does R5F101BCANA#40 use?
R5F101BCANA#40 uses a 36-pin HWQFN package (Renesas code PWQN0036KA-A) measuring 4 mm × 4 mm with 0.5 mm pitch and an exposed thermal pad. This compact, surface-mount package supports high-density PCB layouts and requires controlled-impedance routing for critical signals such as RESET and clock inputs.
Which low-power modes are supported by R5F101BCANA#40, and what is the lowest achievable current draw?
R5F101BCANA#40 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.57 μA (typical) at VDD = 1.8 V and TA = 25°C. This ultra-low quiescent current enables multi-year operation on coin-cell batteries in intermittent-sensing applications without compromising timekeeping accuracy.
Can R5F101BCANA#40 operate with a 32.768 kHz external crystal for RTC accuracy?
Yes, R5F101BCANA#40 supports external 32.768 kHz crystal connection via CLKP/CLKM pins to drive its real-time clock with ±20 ppm accuracy. When used, the RTC maintains calendar, alarm, and clock correction functions independently of the main system clock - critical for time-stamped logging in energy metering and environmental monitoring applications.
