Product details
Overview
R5F104GCGFB#30 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 128 KB flash, 12 KB RAM, and 8 KB data flash. It integrates a 32 MHz RL78 CPU core delivering 44 DMIPS, ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD), and mixed-signal peripherals including 10-bit ADC (16 channels), dual 8-bit DACs, and real-time clock - deployed in battery-powered sensor nodes and motor control interfaces.
For engineers reviewing the R5F104GCGFB#30 datasheet, R5F104GCGFB#30 pinout, R5F104GCGFB#30 application, or R5F104GCGFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package compatibility, −40°C to +105°C industrial temperature rating, integrated DTC/ELC for deterministic peripheral chaining, and support for background data flash rewriting at VDD = 1.8–5.5 V without CPU stall.
Technical Context
The R5F104GCGFB#30 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 supports multiply/divide/accumulate instructions and 1 MB address space across four register banks.
Its peripheral set includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, calendar RTC with alarm/correction, watchdog timer, and serial interfaces: 3× UART/LIN, 4× CSI (SPI-compatible), and 4× I²C - all linked via Event Link Controller (ELC) for hardware-triggered, low-latency event routing without CPU intervention.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GCGFB#30?
The R5F104GCGFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 44 DMIPS performance. This execution speed is confirmed in the RL78/G14 datasheet Rev. 3.70, Section 1.1, and applies directly to the R5F104GCGFB#30 as a G-grade member of the 128 KB flash variant group.
Does the R5F104GCGFB#30 support background data flash rewriting while executing code from main flash memory?
Yes, the R5F104GCGFB#30 supports background operation (BGO) for data flash. Instructions can be fetched and executed from code flash memory while simultaneously rewriting the 8 KB data flash - a capability documented in Section 1.1 "Data Flash Memory" of the R01DS0053EJ0370 datasheet for the R5F104GCGFB#30's RL78/G14 family.
What is the analog reference voltage source available for the 10-bit ADC in the R5F104GCGFB#30?
The R5F104GCGFB#30 ADC supports an internal 1.45 V reference voltage, explicitly listed in the "A/D Converter" section of the datasheet. This reference is stable across VDD = 1.6–5.5 V and temperature, enabling accurate analog measurements without external components - a confirmed feature for the R5F104GCGFB#30.
Which package type and pin count does the R5F104GCGFB#30 use, and what is its pitch?
The R5F104GCGFB#30 uses a 48-pin LFQFP package with 0.5 mm pitch, as defined in the ordering information (Section 1.2) and confirmed in Table 1-1 "List of Ordering Part Numbers (2/5)" where "FB" denotes LFQFP and "G" indicates 48-pin count. The Renesas code PLQP0048KF-A verifies this mechanical form factor.
What is the guaranteed operating ambient temperature range for the R5F104GCGFB#30?
The R5F104GCGFB#30 is rated for −40°C to +105°C ambient operation, indicated by the "G" suffix in its part number per Figure 1-1 and Section 1.2 of the datasheet. This industrial temperature grade is validated for continuous operation in motor drives, power supplies, and HVAC systems where thermal stress exceeds commercial limits.
