Product details
Overview
R5F104MLAFA#30 from Renesas is a 80-pin LQFP-0.65mm MCU in the RL78/G14 family, featuring 256 KB flash, 24 KB RAM, and operation from 1.6 V to 5.5 V. It delivers 44 DMIPS at 32 MHz, supports ultra-low-power modes (0.60 μA RTC+LVD), and integrates 12-bit ADC (16 ch), UART/LIN (4 ch), I²C (10 ch), and real-time clock with calendar function - deployed in industrial motor control and smart sensor nodes.
For engineers reviewing the R5F104MLAFA#30 datasheet, R5F104MLAFA#30 pinout, R5F104MLAFA#30 application, or R5F104MLAFA#30 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade (D-grade), 80-pin LQFP package with 0.65 mm pitch, integrated data flash (8 KB), and support for background data flash rewriting during program execution.
Technical Context
The R5F104MLAFA#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 includes Event Link Controller (ELC) for hardware-triggered peripheral chaining and Data Transfer Controller (DTC) supporting block, repeat, and chain transfer modes activated by interrupts.
It integrates dual-clock domains: high-speed on-chip oscillator (selectable up to 32 MHz ±1.0% accuracy) and subsystem clock (32.768 kHz crystal or RC), enabling independent operation of RTC, LVD, and low-power peripherals during HALT/STOP modes - critical for battery-backed industrial monitoring systems.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104MLAFA#30?
The R5F104MLAFA#30 operates at up to 32 MHz and achieves 44 DMIPS performance. This is measured using the EEMBC CoreMark benchmark under standard conditions (VDD = 3.3 V, TA = 25°C) and reflects the RL78 CPU's optimized 3-stage pipeline and instruction set efficiency. The R5F104MLAFA#30 maintains this performance across its full 1.6–5.5 V supply range with appropriate clock configuration.
Does the R5F104MLAFA#30 support hardware-based peripheral event chaining without CPU intervention?
Yes, the R5F104MLAFA#30 includes an Event Link Controller (ELC) that enables direct hardware routing of up to 26 event sources (e.g., timer overflow, ADC end-of-conversion) to target peripherals such as timers, DMA, or GPIO. This eliminates software latency and CPU polling, allowing deterministic response times - a key feature confirmed in the R01DS0053EJ0370 datasheet Section 1.1.
What is the data flash endurance and voltage range for rewriting on the R5F104MLAFA#30?
The R5F104MLAFA#30 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows concurrent code execution from main flash during data flash programming - a verified capability documented in Section 1.1 "Data Flash Memory" of the R01DS0053EJ0370 datasheet.
Is the R5F104MLAFA#30 qualified for industrial temperature operation, and what grade does it carry?
Yes, the R5F104MLAFA#30 is qualified for industrial ambient temperatures from -40°C to +85°C and carries the 'D' grade designation per Renesas ordering nomenclature. This grade is explicitly assigned to all R5F104xLAFA#30 variants in Table 1-1 of the R01DS0053EJ0370 datasheet, confirming suitability for factory automation, motor drives, and outdoor infrastructure applications.
How many analog input channels does the 12-bit ADC support on the R5F104MLAFA#30, and does it include internal reference?
The R5F104MLAFA#30 integrates a 12-bit successive-approximation ADC with up to 16 analog input channels (ANI0–ANI19, excluding reserved pins), and includes an internal reference voltage of 1.45 V (±2%) as well as a built-in temperature sensor. These specifications are confirmed in Section 1.1 "A/D Converter" and the pin configuration table for 80-pin LQFP packages in the R01DS0053EJ0370 datasheet.
