Product details
Overview
R5F104MLAFB#30 from Renesas is an RL78/G14 80-pin LFQFP microcontroller with 256 KB flash, 8 KB data flash, and 24 KB RAM, operating at 32 MHz (44 DMIPS), supporting ultra-low-power modes (0.60 μA in RTC+LVD mode), 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in industrial motor control and sensor node firmware.
For engineers reviewing the R5F104MLAFB#30 datasheet, R5F104MLAFB#30 pinout, R5F104MLAFB#30 application, or R5F104MLAFB#30 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature range (G-grade), 0.5 mm pitch LFQFP-80 package, integrated event link controller (ELC) for peripheral synchronization, and hardware DTC for zero-CPU-load data transfers.
Technical Context
The R5F104MLAFB#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), plus multiply/divide/accumulate instructions and 1 MB address space.
It integrates a configurable Event Link Controller (ELC) enabling 19–26 event sources to trigger peripheral functions without CPU intervention, and a Data Transfer Controller (DTC) supporting normal, repeat, block, and chain transfer modes activated by interrupts - reducing firmware overhead in real-time I/O handling.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104MLAFB#30?
The R5F104MLAFB#30 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating is achieved using the high-speed on-chip oscillator (±1.0% accuracy across -40°C to +105°C), and the RL78 CPU core's 3-stage pipeline ensures deterministic execution timing critical for real-time control loops in the R5F104MLAFB#30.
Does the R5F104MLAFB#30 support background data flash rewriting while executing code from main flash?
Yes, the R5F104MLAFB#30 supports Background Operation (BGO) for data flash. It allows program execution from code flash while simultaneously rewriting the 8 KB data flash memory - essential for non-disruptive firmware parameter updates or logging in the R5F104MLAFB#30 without halting real-time tasks.
What are the power consumption values for HALT and STOP modes in the R5F104MLAFB#30?
In HALT mode, the R5F104MLAFB#30 consumes 66 μA per MHz of active clock frequency. In STOP mode with only RTC and LVD enabled, it draws just 0.60 μA - verified across the full -40°C to +105°C industrial temperature range, making the R5F104MLAFB#30 ideal for decade-long battery deployments.
Which communication interfaces are available on the R5F104MLAFB#30, and how many instances does it support?
The R5F104MLAFB#30 integrates UART/UART (LIN-capable) with 4 channels, simplified SPI (CSI) with up to 8 channels, and I²C/simplified I²C with up to 10 channels. All interfaces are multiplexed across GPIO pins and configurable via peripheral I/O redirection registers - maximizing flexibility in the R5F104MLAFB#30's 80-pin layout.
Is the R5F104MLAFB#30 qualified for industrial temperature range, and what grade designation confirms this?
Yes, the R5F104MLAFB#30 is rated for -40°C to +105°C operation and carries the 'G' grade designation in its part number suffix - explicitly indicating industrial qualification per Renesas' ordering nomenclature. This makes the R5F104MLAFB#30 suitable for demanding environments such as factory automation, motor drives, and outdoor sensor enclosures.
