Product details
Overview
R5F104BFGFP#10 from Renesas is a 32-bit RL78/G14 microcontroller featuring 96 KB flash memory, 12 KB RAM, and 48-pin LFQFP (0.5 mm pitch) packaging. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, supports -40°C to +85°C industrial temperature range (D-grade), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (12 channels), and ultra-low-power HALT/STOP/SNOOZE modes for battery-powered sensor nodes.
For engineers reviewing the R5F104BFGFP#10 datasheet, R5F104BFGFP#10 pinout, R5F104BFGFP#10 application, or R5F104BFGFP#10 equivalent, key selection criteria include its 48-pin LFQFP package with dedicated RTC, LVD, and background data flash rewrite capability - critical for firmware-over-the-air (FOTA) updates in industrial control and smart metering designs.
Technical Context
The R5F104BFGFP#10 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 ultra-low-speed mode). It embeds a Data Transfer Controller (DTC) for autonomous peripheral-to-memory transfers and an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its power management includes on-chip POR, 14-level voltage detector (LVD), and true low-power operation: 66 µA/MHz active current and 0.60 µA in STOP mode with RTC + LVD active. The high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) eliminates external crystal dependency for cost-sensitive applications.

FAQ
What is the maximum operating frequency and core performance of the R5F104BFGFP#10?
The R5F104BFGFP#10 operates at up to 32 MHz with the RL78 CPU core delivering 44 DMIPS. Its 3-stage pipeline supports minimum instruction execution times ranging from 0.03125 µs (at 32 MHz with high-speed on-chip oscillator) to 30.5 µs (at 32.768 kHz), enabling flexible trade-offs between speed and ultra-low-power operation. This makes R5F104BFGFP#10 suitable for both responsive control tasks and extended battery life in intermittent-use devices.
Does the R5F104BFGFP#10 support in-system programming and secure firmware updates?
Yes, the R5F104BFGFP#10 supports robust in-system programming via its on-chip debug function and self-programming capabilities. It implements boot swapping and flash shield window protection to prevent unauthorized access during firmware updates. The 96 KB code flash is organized in 1 KB blocks, and block erase/write prohibition enhances security. These features allow safe, field-upgradable firmware deployment - a key requirement for R5F104BFGFP#10 in deployed industrial assets.
What are the power management modes supported by the R5F104BFGFP#10, and what are their typical current draws?
The R5F104BFGFP#10 supports HALT, STOP, and SNOOZE low-power modes. In active mode, it consumes 66 µA per MHz; in STOP mode with only RTC and LVD active, current drops to 0.60 µA. HALT mode reduces current to ~1.2 µA while preserving RAM and register contents. SNOOZE enables selective peripheral operation (e.g., ADC conversion or UART receive) with sub-10 µA average current - all critical for extending battery life in R5F104BFGFP#10-based portable and remote sensing applications.
How many analog-to-digital converter (ADC) channels does the R5F104BFGFP#10 provide, and what is its resolution and reference voltage?
The R5F104BFGFP#10 integrates a 10-bit successive-approximation ADC with 12 analog input channels. It supports an internal reference voltage of 1.45 V and includes an on-chip temperature sensor. The ADC operates across the full 1.6–5.5 V supply range, enabling accurate measurements even under varying rail conditions. This ADC configuration is directly leveraged in R5F104BFGFP#10 designs for environmental monitoring, motor current sensing, and power supply supervision.
Is the R5F104BFGFP#10 pin-compatible with other RL78/G14 family members in the same package?
Yes, the R5F104BFGFP#10 is pin-compatible with other 48-pin LFQFP variants in the RL78/G14 family, including R5F104GFGFP#10 (256 KB flash) and R5F104LFGFP#10 (512 KB flash), provided they share the same FB suffix and D-grade temperature rating. Pin functions, power domains, and peripheral mappings are consistent across these variants, enabling memory-scalable design reuse. This compatibility simplifies migration paths and reduces qualification effort for R5F104BFGFP#10-based platforms.
