Product details
Overview
R5F104GGGFB#30 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, and features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), making it suitable for battery-powered industrial sensors and motor control edge nodes.
For engineers reviewing the R5F104GGGFB#30 datasheet, R5F104GGGFB#30 pinout, R5F104GGGFB#30 application, or R5F104GGGFB#30 equivalent, key selection considerations include its integrated 10-bit ADC (20 channels), dual UART/LIN support, real-time clock with calendar, and hardware DTC/ELC for deterministic peripheral event handling in resource-constrained embedded systems.
Technical Context
The R5F104GGGFB#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a configurable Event Link Controller (ELC) enabling direct peripheral-to-peripheral signal routing without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes, plus an on-chip voltage detector (LVD) with 14 selectable threshold levels and a POR circuit. The device supports background operation (BGO) for data flash rewriting while executing code from program memory.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104GGGFB#30?
The R5F104GGGFB#30 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. This speed is fully supported across its −40°C to +105°C industrial temperature range and 1.6–5.5 V supply voltage, enabling deterministic real-time control in demanding applications such as motor commutation and sensor fusion.
Does the R5F104GGGFB#30 support LIN communication, and how is it implemented?
Yes, the R5F104GGGFB#30 supports LIN 2.2 communication through its UART peripherals, which include dedicated LIN-mode configuration registers and automatic header detection. The UART can generate break fields, sync bytes, and identifier bytes per LIN specification, and supports slave node operation with checksum verification - all without CPU intervention via ELC-triggered DTC transfers.
What are the flash memory endurance and data retention specifications for the R5F104GGGFB#30?
The R5F104GGGFB#30 specifies 1,000,000 write/erase cycles for its 8 KB data flash memory, with guaranteed data retention of 20 years at +85°C and 100 years at +25°C. Code flash endurance is rated at 10,000 cycles. These values are measured under standard VDD = 1.8–5.5 V conditions and apply to both standard and secure erase operations.
How does the R5F104GGGFB#30 manage power in battery-operated applications?
The R5F104GGGFB#30 minimizes power in battery applications via multiple low-power modes: HALT (66 μA/MHz), STOP (0.60 μA with RTC + LVD active), and SNOOZE (selective peripheral wake-up). Its on-chip LVD provides 14 programmable voltage thresholds for graceful shutdown, and the RTC maintains calendar accuracy with ±1.5 ppm drift over temperature - enabling decade-scale operation on coin cells.
Is the R5F104GGGFB#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, the R5F104GGGFB#30 is fully pin-compatible with all other RL78/G14 devices in the 48-pin LFQFP (FB) package, including R5F104GHGFB#30 and R5F104GJGFB#30.
