Product details
Overview
R5F104BGDFP#V0 from Renesas Electronics is a 32-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 48-pin LFQFP (0.5 mm pitch) package, operating at 1.6–5.5 V and delivering 44 DMIPS at 32 MHz. It integrates 10-bit ADC (16 channels), dual UART/LIN, I²C, CSI, 16-bit timers, RTC, and ultra-low-power modes (0.60 μA in STOP with RTC+LVD), targeting battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F104BGDFP#V0 datasheet, R5F104BGDFP#V0 pinout, R5F104BGDFP#V0 application, or R5F104BGDFP#V0 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +85°C), integrated data flash (8 KB), hardware event linking (ELC), and background operation for data flash rewriting-critical for firmware-over-the-air (FOTA) and real-time calibration in field-deployed devices.
Technical Context
The R5F104BGDFP#V0 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). Its on-chip peripherals include Timer Array Unit (TAU) with 8 channels, Real-time Clock with calendar and alarm, and Data Transfer Controller (DTC) enabling interrupt-triggered memory transfers without CPU intervention.
Power management includes HALT, STOP, and SNOOZE modes, with voltage detector (LVD) offering 14 selectable reset/interrupt thresholds and POR circuitry. The Event Link Controller (ELC) supports configurable routing of 19–26 event sources-including timer overflows, ADC completions, and communication interrupts-to peripheral functions, enabling deterministic low-latency response without software polling.

This performance level supports real-time control loops, protocol stack processing, and sensor fusion algorithms within the R5F104BGDFP#V0's power envelope.
Does the R5F104BGDFP#V0 support in-system programming and secure firmware updates?
Yes, the R5F104BGDFP#V0 supports self-programming with boot swap functionality and flash shield window protection. It allows safe firmware updates by maintaining separate active/inactive code banks and restricting erase/write access to designated flash regions. The R5F104BGDFP#V0 also includes on-chip debug capability compliant with IEEE 1149.1 (JTAG) for development and field diagnostics.
How does the R5F104BGDFP#V0 manage ultra-low-power operation in battery-powered applications?
The R5F104BGDFP#V0 achieves 0.60 μA in STOP mode with RTC and LVD active, and 66 μA/MHz in HALT mode. Its power management includes multiple low-power states, programmable LVD thresholds (14 levels), and automatic peripheral clock gating. These features enable multi-year battery life in applications like wireless sensor nodes-where the R5F104BGDFP#V0 remains in STOP mode between periodic RTC wake-ups for sensor reading and transmission.
What analog and mixed-signal peripherals are integrated into the R5F104BGDFP#V0?
The R5F104BGDFP#V0 integrates a 10-bit ADC with 16 input channels, internal 1.45 V reference voltage, and on-die temperature sensor; an 8-bit DAC with up to two output channels; and two comparators with window mode. It also includes a real-time clock with calendar, alarm, and clock correction functions. These peripherals allow the R5F104BGDFP#V0 to perform sensor signal acquisition, calibration, and local decision-making without external components.
Can the R5F104BGDFP#V0 interface directly with industrial communication buses such as LIN or RS-485?
Yes, the R5F104BGDFP#V0 includes three UART channels with built-in LIN bus support (break detection, sync byte handling, checksum generation), making it suitable for automotive and industrial sub-networks. When paired with a standard RS-485 transceiver (e.g., SN65HVD72), the R5F104BGDFP#V0 can implement robust half-duplex differential communication for PLC I/O modules or building automation controllers.
