Product details
Overview
R5F104BGAFP#10 from Renesas is a 32-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 48-pin LFQFP (0.5 mm pitch) package, operating from 1.6–5.5 V at –40 to +85°C. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/LIN, I²C, SPI, RTC, and on-chip debug for industrial control applications.
For engineers reviewing the R5F104BGAFP#10 datasheet, R5F104BGAFP#10 pinout, R5F104BGAFP#10 application, or R5F104BGAFP#10 equivalent, this page provides verified technical context, validated pin functions, real-world use cases in motor control and sensor hubs, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The R5F104BGAFP#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It supports multiply/divide/accumulate instructions and 1 MB address space with four banks of 8-bit general-purpose registers.
It integrates dual flash memory: 96 KB code flash (1 KB block size, security-protected erase/write) and 8 KB data flash with background operation (BGO), 1M rewrite cycles, and VDD = 1.8–5.5 V programming voltage. Peripheral subsystems include Event Link Controller (ELC) for 19–26 event routing, Data Transfer Controller (DTC), and simplified SPI (CSI), UART/LIN, and I²C interfaces.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104BGAFP#10?
The R5F104BGAFP#10 operates up to 32 MHz with an RL78 CPU core delivering 44 DMIPS. This performance level supports real-time control algorithms such as field-oriented control (FOC) for motors or fast sensor fusion in edge nodes. The high-speed on-chip oscillator achieves ±1.0% accuracy across 1.8–5.5 V and –20 to +85°C, eliminating need for external crystals in many applications.
Does the R5F104BGAFP#10 support in-system programming and secure firmware updates?
Yes, the R5F104BGAFP#10 supports self-programming with boot swapping and flash shield window functionality. This enables secure over-the-air (OTA) or field firmware updates while protecting critical bootloader sections from accidental or malicious overwrite. The flash library uses designated RAM areas (start address FE900H) and requires no external programming hardware.
How many analog input channels does the R5F104BGAFP#10 ADC support, and what reference options are available?
The R5F104BGAFP#10 integrates a 10-bit successive-approximation ADC with up to 16 analog input channels. It supports both internal 1.45 V reference and external references via AVREFP/AVREFM pins, enabling ratiometric measurements across variable supply voltages. Temperature sensor and internal reference voltage measurement are also supported.
What low-power modes are available on the R5F104BGAFP#10, and what is the lowest achievable current draw?
The R5F104BGAFP#10 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.60 μA typical - ideal for battery-powered devices requiring periodic wake-up. HALT mode consumes 66 μA/MHz, and SNOOZE enables peripheral operation (e.g., ADC conversion) while CPU remains halted, optimizing power/performance trade-offs.
Is the R5F104BGAFP#10 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 48-pin LFQFP package (e.g., R5F104CGAFP#10, R5F104DGAFP#10) share identical pinouts and electrical characteristics. This allows hardware reuse across firmware variants - for example, upgrading flash capacity without PCB redesign. Pin functions are consistent; only memory sizes and some peripheral enablement differ per part number.
