Product details
Overview
R5F104GCAFB#30 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash. It operates from 1.6–5.5 V, delivers 44 DMIPS at 32 MHz, and supports ultra-low-power modes (0.60 μA in RTC+LVD mode), targeting battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F104GCAFB#30 datasheet, R5F104GCAFB#30 pinout, R5F104GCAFB#30 application, or R5F104GCAFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, integrated 10-bit ADC (20-channel), 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 R5F104GCAFB#30 implements the RL78 CPU core with 3-stage pipeline, 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 integrates a Data Transfer Controller (DTC) for autonomous memory transfers triggered by 19–26 peripheral events via the Event Link Controller (ELC).
It features a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, two 8-bit D/A channels with real-time output, and up to two comparators with selectable internal/external reference. The on-chip high-accuracy oscillator offers ±1.0% stability across –40°C to +105°C.

The R5F104GCAFB#30 is rated for industrial operation from –40°C to +105°C, as indicated by the 'G' suffix in the part number. This makes it suitable for deployment in harsh environments such as factory automation panels, outdoor metering enclosures, and under-hood industrial gateways where ambient temperatures exceed standard commercial limits.
Does the R5F104GCAFB#30 support LIN bus communication?
Yes, the R5F104GCAFB#30 supports LIN bus communication through its UART peripherals, which include LIN-bus protocol support per the RL78/G14 datasheet. Specifically, UART channels can be configured for LIN 2.2A compliance with automatic sync-break detection and checksum generation - enabling direct connection to automotive and industrial LIN slave nodes without external transceivers.
How much data flash endurance does the R5F104GCAFB#30 provide?
The R5F104GCAFB#30 includes 8 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. This endurance, combined with background operation (BGO), allows reliable storage of calibration data, device configuration, and usage logs in applications like smart meters and predictive maintenance sensors where frequent nonvolatile updates are required.
Can the R5F104GCAFB#30 operate from a single 1.8 V supply?
Yes, the R5F104GCAFB#30 supports single-supply operation from 1.6 V to 5.5 V, including stable operation at 1.8 V. Its ultra-low-power HALT and STOP modes remain fully functional at this voltage, enabling direct integration with 1.8 V logic families and energy-harvesting power sources - no level shifters or regulators needed for compatible subsystems.
What debugging interfaces are supported by the R5F104GCAFB#30?
The R5F104GCAFB#30 supports on-chip debug via the dedicated TOOL0 pin (P40) and TRJIO/TRJO signals mapped to multiple GPIOs (e.g., P00, P01, P31), enabling connection to Renesas E2 emulator or compatible JTAG/SW-DP debug probes.
