Product details
Overview
R5F100BGANA#20 from Renesas is a 32-pin RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), and real-time clock with calendar support - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100BGANA#20 datasheet, R5F100BGANA#20 pinout, R5F100BGANA#20 application, or R5F100BGANA#20 equivalent, key selection criteria include its VFBGA-32 package (0.4 mm pitch), -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, and background data flash rewriting capability for firmware updates without halting execution.
Technical Context
The R5F100BGANA#20 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with alarm/calendar, 2–4 channel DMA, UART/LIN, I²C, CSI, 10-bit ADC with internal reference (1.45 V) and temperature sensor, and hardware multiplier/divider/MAC units - all optimized for deterministic real-time control in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101BGANA#20 | No data flash (0 KB); identical core, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or firmware logging | Select when data retention is handled externally or not required |
| R5F100BGASP#V0 | LSSOP-30 package (7.62 mm, 0.65 mm pitch); same memory and specs | Requires PCB redesign due to different footprint, pin count (30 vs 32), and thermal profile | Choose for through-hole prototyping or legacy LSSOP-compatible designs |
Compared with R5F100BGANA#20, R5F101BGANA#20 removes data flash to reduce cost and die size but sacrifices field-upgradable configuration storage, while R5F100BGASP#V0 trades the compact VFBGA for a larger, leaded LSSOP package - impacting board area, thermal performance, and reflow process compatibility.

FAQ
What is the operating temperature range of the R5F100BGANA#20?
The R5F100BGANA#20 is rated for industrial operation from -40°C to +105°C (G-grade), validated across its full 1.6 V to 5.5 V supply range. This makes it suitable for deployment in harsh environments such as factory floors, outdoor utility meters, and under-hood automotive auxiliary systems where thermal stability is critical. The device maintains specified timing, ADC accuracy, and flash write endurance across this range.
Does the R5F100BGANA#20 support in-system programming without external hardware?
Yes, the R5F100BGANA#20 supports full in-system programming via its on-chip debug interface using standard SWD or FINE protocols. It includes boot swap functionality and flash shield window protection, enabling secure firmware updates directly over UART, I²C, or CAN - no external programmer or debug probe is required for field deployments. The R5F100BGANA#20 also permits background data flash writes during normal program execution.
How many analog input channels does the R5F100BGANA#20 provide, and what is the ADC resolution?
The R5F100BGANA#20 integrates a 10-bit successive-approximation ADC with up to 26 configurable analog input channels (ANI0–ANI25), including dedicated AVREFP/AVREFM pins for precise ratiometric measurements. It supports internal 1.45 V reference voltage and on-chip temperature sensing - both usable only in HS (high-speed) mode. Conversion time is programmable down to 1.5 μs per sample.
What package type and footprint does the R5F100BGANA#20 use?
The R5F100BGANA#20 uses a VFBGA-32 package (Renesas code PVBG0032LA-A): 4 mm × 4 mm body, 0.4 mm ball pitch, 32 solder balls arranged in a 6×6 grid with corner balls omitted. It is lead-free, RoHS-compliant, and designed for fine-pitch reflow assembly. This compact, low-inductance package improves thermal dissipation and EMI performance compared to QFP alternatives.
Can the R5F100BGANA#20 operate from a single 1.8 V supply?
Yes, the R5F100BGANA#20 supports operation from 1.6 V to 5.5 V, making 1.8 V fully valid. At 1.8 V, maximum clock frequency is reduced to 16 MHz (per datasheet DC characteristics), delivering ~20.5 DMIPS. All peripherals - including ADC, RTC, and serial interfaces - remain functional, though ADC accuracy and flash write voltage requirements must be verified per the electrical characteristics table in R01DS0131EJ0380.
