Product details
Overview
R5F104MGAFB#X0 from Renesas is a 80-pin LFQFP (0.5 mm pitch), industrial-grade RL78/G14 16-bit 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, supports -40°C to +105°C ambient, and integrates RTC, 10-bit ADC (19 channels), UART/SPI/I²C interfaces, and ultra-low-power HALT/STOP/SNOOZE modes for battery-powered sensor nodes and motor control.
For engineers reviewing the R5F104MGAFB#X0 datasheet, R5F104MGAFB#X0 pinout, R5F104MGAFB#X0 application, or R5F104MGAFB#X0 equivalent, key selection criteria include its 80-pin LFQFP-0.5mm package, G-grade temperature rating, integrated 10-bit ADC with 19 inputs, dual UART with LIN support, and on-chip data flash with 1M-cycle endurance for firmware-over-the-air updates.
Technical Context
The R5F104MGAFB#X0 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 configurable high-speed on-chip oscillator (±1.0% accuracy across 1–64 MHz) and dedicated low-speed oscillator for watchdog and RTC operation.
Peripheral integration includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) supporting block/repeat transfers, and simplified SPI (CSI), UART/LIN, and I²C interfaces - all configurable via peripheral I/O redirection registers (PIOR0/1) without requiring PCB changes.

FAQ
What is the operating temperature range for the R5F104MGAFB#X0?
The R5F104MGAFB#X0 is rated for industrial applications with an operating ambient temperature range of -40°C to +105°C (G-grade), validated per Renesas specification R01DS0053EJ0340. This makes it suitable for under-hood automotive modules, factory-floor controllers, and outdoor metering equipment where extended thermal stability is required. The device maintains full functionality-including RTC, ADC accuracy, and flash programming-across this entire range.
Does the R5F104MGAFB#X0 support LIN bus communication?
Yes, the R5F104MGAFB#X0 supports LIN bus communication through its UART peripherals, which are explicitly documented as LIN-capable in the R01DS0053EJ0340 datasheet. Up to three UART channels (e.g., UART0, UART1, UART2) can operate in LIN mode with automatic sync-break detection, checksum calculation, and identifier filtering - enabling direct connection to LIN transceivers without external protocol assist chips.
How many analog input channels does the R5F104MGAFB#X0 ADC support?
The R5F104MGAFB#X0 integrates a 10-bit successive-approximation ADC with up to 19 analog input channels, as confirmed in Section 1.1 "Features" and Table 1-1 of the R01DS0053EJ0340 datasheet. These include dedicated ANI0–ANI19 pins plus VCOUT0/VCOUT1 for on-chip voltage references, supporting simultaneous sampling for multi-sensor systems like HVAC control or power quality monitoring.
What packaging format is used for the R5F104MGAFB#X0?
The R5F104MGAFB#X0 uses embossed tape packaging (JEDEC standard), indicated by the "#X0" suffix per Renesas ordering information in Section 1.2 of R01DS0053EJ0340. This 8-mm carrier tape format is optimized for high-speed pick-and-place SMT assembly, with 1,000 units per reel, and complies with moisture sensitivity level MSL3 per J-STD-020.
Can the R5F104MGAFB#X0 perform flash self-programming during runtime?
Yes, the R5F104MGAFB#X0 supports full flash self-programming, including both code flash and data flash, using the on-chip Flash Self-Programming Library (R20UT2944). It enables background operation (BGO) for data flash writes, allowing program execution to continue uninterrupted - critical for firmware updates in always-on systems. The library reserves specific RAM regions (e.g., F9F00H for R5F104xJ variants) as documented in the datasheet's memory map section.
