Product details
Overview
R5F104LCGFP#V0 from Renesas Electronics is a 64-pin LFQFP-packaged RL78/G14 16-bit microcontroller with 512 KB flash, 48 KB RAM, and 8 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (44 DMIPS). It integrates RTC, 12-bit ADC (20 channels), dual DAC, UART/SPI/I²C interfaces, and ultra-low-power modes (0.60 μA in RTC+LVD mode), targeting battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F104LCGFP#V0 datasheet, R5F104LCGFP#V0 pinout, R5F104LCGFP#V0 application, or R5F104LCGFP#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm pitch package, industrial-grade -40°C to +105°C operation (G-grade), integrated event link controller (ELC) for peripheral coordination, and background data flash rewriting capability.
Technical Context
The R5F104LCGFP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It features a programmable high-speed on-chip oscillator (±1.0% accuracy across 1–64 MHz) and dedicated low-speed oscillator for watchdog timing.
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, real-time clock with calendar/alarm, 8/10-bit ADC with internal 1.45 V reference and temperature sensor, and DTC for autonomous data transfers triggered by interrupts - enabling deterministic low-CPU-load system control.

FAQ
What is the maximum operating frequency and associated performance of the R5F104LCGFP#V0?
The R5F104LCGFP#V0 operates at up to 32 MHz with a measured performance of 44 DMIPS. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 64 MHz with ±1.0% tolerance across the full industrial temperature range (-40°C to +105°C) and supply voltage (1.6 V to 5.5 V), enabling deterministic real-time response without external crystal dependency.
Does the R5F104LCGFP#V0 support in-system programming and secure firmware updates?
Yes, the R5F104LCGFP#V0 supports full in-system programming via on-chip debug interface and includes boot swap functionality with flash shield window protection. This allows authenticated firmware updates in the field while preventing unauthorized readout or modification of protected code flash blocks - critical for certified industrial and medical deployments.
What analog peripherals are integrated into the R5F104LCGFP#V0 and how are they configured?
The R5F104LCGFP#V0 integrates an 8/10-bit successive-approximation ADC with 20 input channels, internal 1.45 V reference, and on-die temperature sensor; plus two 8-bit voltage-output DACs. Configuration is performed via dedicated peripheral registers - ADC resolution, sample rate, and reference source are software-selectable, while DAC outputs support real-time simultaneous update for waveform synthesis.
How does the Event Link Controller (ELC) enhance system efficiency in the R5F104LCGFP#V0?
The ELC in the R5F104LCGFP#V0 enables direct hardware-level linking of up to 26 peripheral events (e.g., ADC conversion complete → DTC transfer start → timer reload), bypassing CPU interrupt handling. This reduces latency to sub-microsecond levels and frees the CPU for higher-layer tasks - essential for deterministic control loops in motor drives and sensor fusion systems.
What power-saving modes are available on the R5F104LCGFP#V0 and what are their typical use cases?
The R5F104LCGFP#V0 offers HALT (66 μA/MHz), STOP (0.60 μA with RTC + LVD active), and SNOOZE modes. STOP mode is used in battery-powered meters for decade-long operation between wake-ups; HALT enables rapid wake/resume in responsive HMI systems; SNOOZE allows peripheral-triggered wake-up with minimal latency for sensor polling intervals.
