Overview
R5F100BCANA#U0 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 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA in RTC+LVD mode), and integrates 10-bit ADC (6 channels), RTC, UART, I²C, and 8×16-bit timers for embedded control in battery-powered and industrial sensing applications.
For engineers reviewing the R5F100BCANA#U0 datasheet, R5F100BCANA#U0 pinout, R5F100BCANA#U0 application, or R5F100BCANA#U0 equivalent, key selection criteria include its 32-pin HWQFN-0.5 mm pitch package, 16 KB code flash with self-programming capability, 10-bit ADC input count, real-time clock calendar function, and support for STOP/HALT/SNOOZE low-power states in resource-constrained designs.
Technical Context
The R5F100BCANA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features on-chip debug, BGO-capable data flash rewriting, and hardware multiplier/divider for efficient signal processing.
Its peripheral set includes up to 8 CSI/SPI channels, 4 UART/LIN interfaces, 10 I²C channels, 16×16-bit timer channels, and a temperature sensor with internal 1.45 V reference-configured via dedicated SFRs and supported by Renesas' RL78-specific toolchain and FDL library.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100BCDFA#V0 | LQFP-32 package (7 × 7 mm, 0.65 mm pitch); identical memory/peripherals but larger footprint and no exposed thermal pad. | Better suited for prototyping or manual assembly where QFN reflow is unavailable; higher thermal resistance limits sustained 32 MHz operation. | Select when board assembly process lacks QFN reflow capability or when thermal load is minimal and layout space permits larger package. |
| R5F101BCANA#U0 | No data flash (0 KB); same 16 KB code flash, 2 KB RAM, and peripherals-but lacks BGO and flash shield window functions. | Applicable where field firmware updates are unnecessary and data logging uses external EEPROM or FRAM. | Choose for cost-sensitive, fixed-function devices where data retention during power loss is handled externally. |
Compared with R5F100BCANA#U0, R5F100BCDFA#V0 trades thermal performance and density for assembly flexibility, while R5F101BCANA#U0 removes data flash to reduce cost and simplify qualification-making each alternative optimal only under specific mechanical, thermal, or lifecycle requirements.

FAQ
What is the maximum operating frequency and associated power consumption of the R5F100BCANA#U0?
The R5F100BCANA#U0 operates up to 32 MHz with 41 DMIPS performance and consumes 66 μA per MHz in active mode. At full speed, typical current draw is ~2.1 mA (32 MHz × 66 μA/MHz), while ultra-low-power STOP mode draws just 0.57 μA with RTC and LVD enabled-verified per R01DS0131EJ0380 Rev.3.80 datasheet Section 1.1.
Does the R5F100BCANA#U0 support in-system programming and secure flash protection?
Yes, the R5F100BCANA#U0 supports full in-system programming via on-chip debug interface and includes flash security features: block erase/write prohibition, boot swap function, and flash shield window to prevent unauthorized access to code memory-detailed in Section 1.1 "Code flash memory" of the R01DS0131EJ0380 datasheet.
How many analog input channels does the R5F100BCANA#U0 ADC support, and what reference options are available?
The R5F100BCANA#U0 integrates a 10-bit successive-approximation ADC with 6 analog input channels (ANI0–ANI5). It supports external reference, internal 1.45 V reference, or AVREFP/AVREFM differential reference-enabling precise measurements without external voltage references, as specified in Section 1.1 "A/D converter".
What low-power modes are available on the R5F100BCANA#U0, and how do they differ in functionality?
The R5F100BCANA#U0 offers HALT (CPU stopped, peripherals active), STOP (all clocks halted except RTC/LVD, 0.57 μA), and SNOOZE (peripheral-triggered wake-up with partial clock gating). Each mode balances wakeup latency, current draw, and peripheral retention-documented in Section 1.1 "Ultra-low power consumption technology" of the datasheet.
Is the R5F100BCANA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 32-pin HWQFN package-including R5F100BCANA#U0, R5F100BDANA#U0, and R5F101BCANA#U0-share identical pinouts and electrical characteristics. Memory size and data flash presence vary by part number, but PCB layout and peripheral routing remain fully compatible across the family.
