Product details
Overview
R5F104FGGFP#30 from Renesas is a 44-pin LQFP, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6 V to 5.5 V. It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/LIN, I²C, SPI, RTC, and 16-bit timers for embedded control in space-constrained industrial sensors.
For engineers reviewing the R5F104FGGFP#30 datasheet, R5F104FGGFP#30 pinout, R5F104FGGFP#30 application, or R5F104FGGFP#30 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options - all aligned to the official RL78/G14 Rev. 3.70 specification and Renesas ordering documentation.
Technical Context
The R5F104FGGFP#30 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 includes on-chip debug, self-programming flash with boot swapping, and background operation (BGO) for data flash writes while executing code.
Its peripheral set includes Timer Array Unit (TAU) with up to 8 channels, Real-time Clock with calendar and alarm, 10-bit A/D converter with internal reference and temperature sensor, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention - critical for deterministic response in motor control and power management systems.

FAQ
What is the maximum operating temperature range for the R5F104FGGFP#30?
The R5F104FGGFP#30 is rated for industrial operation from −40°C to +105°C, as indicated by the 'G' suffix in its part number. This wide temperature range supports deployment in harsh environments such as factory automation cabinets, outdoor power converters, and engine bay-adjacent control units - all while maintaining full specification compliance for flash endurance, ADC accuracy, and timing stability.
Does the R5F104FGGFP#30 support LIN bus communication?
Yes, the R5F104FGGFP#30 supports LIN bus communication through its UART peripheral, which includes dedicated LIN 2.2 features such as automatic break detection, sync field generation, and checksum calculation. The R5F104FGGFP#30 requires only an external LIN transceiver (e.g., TLE7259) to implement full physical-layer compliance - no additional firmware overhead or external logic is needed.
How much data flash memory does the R5F104FGGFP#30 include, and what is its endurance?
The R5F104FGGFP#30 includes 8 KB of on-chip data flash memory, rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. This enables robust non-volatile storage for calibration data, device configuration, and event logs - and supports background operation (BGO), allowing program execution to continue uninterrupted during data flash updates.
Can the R5F104FGGFP#30 operate from a single 3.3 V supply?
Yes, the R5F104FGGFP#30 operates reliably from a single 3.3 V supply, well within its specified 1.6 V to 5.5 V VDD range. At 3.3 V, it achieves full 32 MHz operation, maintains 10-bit ADC accuracy with internal reference, and sustains all low-power modes - making it ideal for mixed-voltage systems where 3.3 V is the primary rail and no level shifting is required for GPIO or serial interfaces.
What debug interface does the R5F104FGGFP#30 support?
The R5F104FGGFP#30 supports on-chip debugging via the single-wire debug (SWD) interface using the TOOL0 and TOOLRxD/TX pins (P40 and P50). It is fully compatible with Renesas E2 emulator and CS+ IDE, enabling breakpoints, real-time variable watch, flash programming, and low-power mode entry/exit tracing - all without requiring additional debug headers or JTAG circuitry.
