Product details
Overview
R5F100BCANA#W0 from Renesas is a 32-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V at -40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (6 channels), RTC, UART, I²C, SPI, and 8×16-bit timers for embedded control in battery-powered and industrial applications.
For engineers reviewing the R5F100BCANA#W0 datasheet, R5F100BCANA#W0 pinout, R5F100BCANA#W0 application, or R5F100BCANA#W0 equivalent, key selection criteria include its 32-pin HWQFN-0.5 mm pitch package, integrated data flash with 1M rewrite cycles, SNOOZE mode for low-power sensor polling, and support for LIN-bus via UART - all critical for cost-sensitive, energy-efficient MCU designs in white goods and industrial HMI.
Technical Context
The R5F100BCANA#W0 implements the RL78 CPU core with a 3-stage CISC 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 with background operation), and SRAM (2 KB), enabling robust firmware updates and real-time data logging without halting program execution.
Power management includes HALT, STOP, and SNOOZE modes, with on-chip POR and LVD (14-level selectable reset/interrupt). Peripheral integration covers 2×UART (LIN-capable), 3×I²C/Simplified I²C, 2×CSI (SPI-compatible), 8×16-bit timers, 1×12-bit interval timer, and 1×RTC with calendar and alarm - all accessible via configurable GPIO with N-ch open-drain, TTL input, and pull-up options.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100BCANA#V0 | Identical silicon; differs only in packaging - tray vs. embossed tape | No functional difference; #V0 used for prototyping and small-batch assembly | Select #W0 for automated SMT production; #V0 for hand-soldered evaluation or low-volume builds |
| R5F101BCANA#W0 | Omits 4 KB data flash; retains same code flash, RAM, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or firmware update staging | Choose R5F101BCANA#W0 only when data flash is unnecessary - reduces cost where EEPROM or external flash is already present |
Compared with R5F100BCANA#W0, the #V0 variant offers identical electrical and functional behavior but requires manual handling due to tray packaging, while R5F101BCANA#W0 removes data flash capability - eliminating background rewrite functionality and reducing total nonvolatile storage to code flash only.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100BCANA#W0?
The R5F100BCANA#W0 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS at that frequency. This performance level is sustained across the full 1.6–5.5 V supply range and -40°C to +85°C ambient temperature, making R5F100BCANA#W0 suitable for real-time control tasks in consumer and industrial equipment without external clock sources.
Does the R5F100BCANA#W0 support hardware LIN bus communication?
Yes, the R5F100BCANA#W0 supports LIN bus communication through its UART peripheral, which includes dedicated LIN-mode functionality such as automatic sync-field detection, checksum calculation, and break signal generation. This eliminates the need for external LIN transceivers in basic implementations and is confirmed in the RL78/G13 datasheet section 1.1 Features under "Serial interface".
What is the data flash endurance and rewrite voltage range for the R5F100BCANA#W0?
The R5F100BCANA#W0 provides 4 KB of data flash rated for 1,000,000 rewrite cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows CPU execution from program memory during rewrites, ensuring deterministic real-time behavior - a key specification confirmed in the RL78/G13 datasheet section 1.1 Features.
Which package type and pin count does the R5F100BCANA#W0 use?
The R5F100BCANA#W0 uses a 32-pin HWQFN package (5 × 5 mm, 0.5-mm pitch), as indicated by the "B" in the part number (32-pin) and "NA" suffix (HWQFN), per Renesas' RL78/G13 part numbering guide in datasheet section 1.2. The #W0 suffix denotes embossed tape packaging for automated SMT placement.
Can the R5F100BCANA#W0 operate from a 1.8 V supply while maintaining full peripheral functionality?
Yes, the R5F100BCANA#W0 operates from 1.6 V to 5.5 V, and all specified peripherals - including 10-bit ADC, RTC, UART, I²C, and timers - remain fully functional at 1.8 V. The datasheet confirms 1.6 V minimum VDD across all operating modes and temperature ranges, enabling direct interface with 1.8 V logic and sensors without level-shifting circuitry.
