Product details
Overview
R5F100BGANA#W0 from Renesas is a 32-pin, VFBGA (4 × 4 mm, 0.4-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode). It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit 26-channel ADC, real-time clock with calendar/alarm, and UART/SPI/I²C interfaces - deployed in battery-powered sensor nodes and smart metering endpoints.
For engineers reviewing the R5F100BGANA#W0 datasheet, R5F100BGANA#W0 pinout, R5F100BGANA#W0 application, or R5F100BGANA#W0 equivalent, key selection criteria include its VFBGA-32 package compatibility with space-constrained PCBs, guaranteed -40°C to +105°C operation (G-grade), integrated data flash rewrite endurance (1M cycles), and support for SNOOZE mode for low-latency peripheral wake-up without CPU intervention.
Technical Context
The R5F100BGANA#W0 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and features an address space of 1 MB. Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - enabling secure self-programming with boot swap and flash shield window functions.
Peripherals include up to 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar and correction, 1× watchdog timer, and serial interfaces: 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible), and 3–10 I²C/Simplified I²C channels. Power management includes HALT/STOP/SNOOZE modes, on-chip POR and LVD (14-level selectable), and DMA controller with 4 channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101BGANA#W0 | No data flash (0 KB); identical core, peripherals, and package | Not suitable for field-upgradable firmware or parameter storage requiring nonvolatile retention | Select when firmware is static and no runtime configuration storage is needed - reduces cost and simplifies flash management |
| STM32G031F8P6 | ARM Cortex-M0+, 64 KB flash, 8 KB RAM, 12-bit ADC (19 ch), operates 1.65–3.6 V only | Lacks RTC calendar, SNOOZE mode, and data flash BGO - requires external RTC or EEPROM for timekeeping/log persistence | Choose for ARM ecosystem alignment and higher single-cycle instruction throughput, but expect added BOM cost for RTC/EEPROM |
Compared with R5F100BGANA#W0, R5F101BGANA#W0 removes data flash to reduce cost and complexity in fixed-function deployments, while STM32G031F8P6 trades RL78's ultra-low-power STOP mode and integrated RTC/calendar for ARM performance and toolchain familiarity - requiring external components to match R5F100BGANA#W0's autonomous timekeeping and field-update capability.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F100BGANA#W0?
The R5F100BGANA#W0 features a high-accuracy on-chip oscillator configurable up to 32 MHz with ±1.0% tolerance across VDD = 1.8–5.5 V and TA = -20°C to +85°C. This eliminates the need for an external crystal in many timing-critical applications while maintaining sufficient stability for UART communication and RTC calibration.
Does R5F100BGANA#W0 support in-system programming and secure firmware updates?
Yes, R5F100BGANA#W0 supports full in-system programming via on-chip debug interface and includes self-programming capabilities with boot swap function and flash shield window protection. These features enable secure over-the-air (FOTA) updates and prevent unauthorized access to protected code regions during field deployment.
How many analog input channels does the 10-bit ADC in R5F100BGANA#W0 support, and what reference options are available?
The R5F100BGANA#W0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference inputs (AVREFP/AVREFM) and an internal 1.45 V reference voltage - selectable in HS (high-speed main) mode - enabling accurate ratiometric measurements without external reference ICs.
What low-power modes are available in R5F100BGANA#W0, and which peripherals remain active in STOP mode?
R5F100BGANA#W0 offers HALT, STOP, and SNOOZE modes. In STOP mode (0.57 μA), the real-time clock (RTC) and low-voltage detector (LVD) remain fully operational, allowing time-based wake-up and brown-out monitoring without CPU involvement - critical for long-life battery applications.
Is R5F100BGANA#W0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the VFBGA-32 package (e.g., R5F100AGANA#W0, R5F100CGANA#W0, R5F101BGANA#W0) share identical pinouts and footprint. This enables hardware reuse across memory/configurations - for example, upgrading from 16 KB to 128 KB flash without PCB redesign.
