Product details
Overview
R5F104BGGFP#V0 from Renesas is a 32-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) package, operating from 1.6–5.5 V at -40 to +105°C (industrial G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates UART, I²C, SPI, 10-bit ADC (16 channels), RTC, and hardware DTC/ELC for sensor and control applications in industrial automation.
For engineers reviewing the R5F104BGGFP#V0 datasheet, R5F104BGGFP#V0 pinout, R5F104BGGFP#V0 application, or R5F104BGGFP#V0 equivalent, key selection considerations include its G-grade temperature rating, 48-pin LFQFP footprint, integrated data flash (8 KB), real-time clock with calendar, and support for background data flash rewriting during program execution.
Technical Context
The R5F104BGGFP#V0 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 uses on-chip high-accuracy oscillator (±1.0% over -20 to +85°C) and supports multiple low-power modes-HALT, STOP, and SNOOZE-with dedicated LVD and POR circuits.
Peripheral integration includes Event Link Controller (ELC) for 19–26 event signal routing, Data Transfer Controller (DTC) with chain transfer, and dual serial interface sets: up to 4 UART/LIN channels, 10 I²C/simplified I²C channels, and 8 CSI (SPI-compatible) channels-enabling concurrent communication in resource-constrained embedded systems.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104BGGFP#V0?
The R5F104BGGFP#V0 operates at a maximum frequency of 32 MHz and achieves 44 DMIPS performance. This metric reflects its RL78 CPU core's optimized 3-stage pipeline and instruction set efficiency. The R5F104BGGFP#V0 maintains this performance across its full industrial temperature range (-40 to +105°C) and supply voltage (1.6–5.5 V), making it suitable for deterministic real-time control tasks in demanding environments.
Does the R5F104BGGFP#V0 support background data flash rewriting while executing code from main flash?
Yes, the R5F104BGGFP#V0 supports Background Operation (BGO) for data flash. Its 8 KB data flash can be rewritten while the CPU executes instructions from code flash-enabling seamless firmware updates, parameter storage, and data logging without interrupting real-time operation. The R5F104BGGFP#V0 guarantees 1,000,000 rewrite cycles and supports VDD = 1.8–5.5 V during rewrites, ensuring robustness in varying supply conditions.
What are the key differences between the R5F104BGGFP#V0 and the R5F104BGGL#V0?
The R5F104BGGFP#V0 and R5F104BGGL#V0 share identical memory (96 KB flash, 12 KB RAM), peripherals, and G-grade temperature rating (-40 to +105°C), but differ in package: R5F104BGGFP#V0 uses 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch), while R5F104BGGL#V0 uses 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) with exposed die pad. The R5F104BGGFP#V0 offers easier inspection and rework; the R5F104BGGL#V0 provides better thermal performance. Neither is pin-compatible due to differing land patterns.
Which serial communication interfaces are available on the R5F104BGGFP#V0, and how many channels does each support?
The R5F104BGGFP#V0 integrates three serial interface types: up to 4 UART/LIN channels (supporting LIN 2.2), up to 10 I²C/simplified I²C channels (including multimaster capability), and up to 8 CSI channels (SPI-compatible with master/slave modes). These are implemented across dedicated peripheral units (SCI, RIIC, and RCSI) and share flexible pin assignment via the Peripheral I/O Redirection Registers (PIOR0/1), allowing dynamic allocation without hardware changes.
How does the Event Link Controller (ELC) enhance real-time performance in the R5F104BGGFP#V0?
The Event Link Controller (ELC) in the R5F104BGGFP#V0 enables direct hardware-level linking of 19–26 peripheral events-such as ADC end-of-conversion, timer overflow, or UART receive complete-to target functions like DTC activation, PWM reload, or interrupt generation-without CPU involvement. This reduces interrupt latency, frees CPU cycles for application logic, and ensures deterministic timing for time-critical operations like synchronized sensor sampling or motor commutation in the R5F104BGGFP#V0.
