Product details
Overview
R5F104LDAFA#V0 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch), industrial-grade RL78/G14 16-bit MCU with 192 KB flash, 20 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at –40 to +85°C. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (16 ch), RTC, and on-chip debug.
For engineers reviewing the R5F104LDAFA#V0 datasheet, R5F104LDAFA#V0 pinout, R5F104LDAFA#V0 application, or R5F104LDAFA#V0 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options for industrial control, sensor hubs, and low-power HMI designs.
Technical Context
The R5F104LDAFA#V0 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 a 1 MB address space with four banks of 8-bit general-purpose registers.
Its peripheral set includes an Event Link Controller (ELC) for hardware-triggered event chaining, Data Transfer Controller (DTC) with block/repeat/chain transfer modes, and dual-voltage interface capability (1.8/2.5/3.0 V I/O compatibility), enabling direct connection to mixed-voltage subsystems without level shifters.

FAQ
What is the maximum operating frequency and core performance of the R5F104LDAFA#V0?
The R5F104LDAFA#V0 operates at up to 32 MHz and delivers 44 DMIPS using the RL78 16-bit CISC core. Its 3-stage pipeline and support for multiply/divide/accumulate instructions enable efficient execution of control algorithms and communication stacks. This performance level is confirmed in the RL78/G14 datasheet (R01DS0053EJ0370) and validated across industrial temperature ranges.
Does the R5F104LDAFA#V0 support hardware-accelerated event chaining between peripherals?
Yes, the R5F104LDAFA#V0 includes an Event Link Controller (ELC) that supports hardware-triggered event chaining across 19–26 peripheral functions. This allows direct peripheral-to-peripheral activation - for example, triggering ADC conversion upon timer match or starting UART transmission after DMA completion - without CPU intervention, reducing latency and power consumption.
What are the memory resources allocated to the R5F104LDAFA#V0?
The R5F104LDAFA#V0 integrates 192 KB of code flash memory, 20 KB of on-chip RAM, and 8 KB of data flash memory. The data flash supports background operation (BGO) and 1,000,000 write cycles, making it suitable for non-volatile parameter storage. These values are explicitly listed in Table 1-1 of the RL78/G14 datasheet for the "L" flash density and "D" variant.
Can the R5F104LDAFA#V0 operate in ultra-low-power modes suitable for battery-powered applications?
Yes, the R5F104LDAFA#V0 supports multiple ultra-low-power modes: HALT (66 μA/MHz), STOP (0.60 μA with RTC and LVD active), and SNOOZE. Its ability to maintain real-time clock operation and voltage monitoring while consuming sub-microamp current makes it ideal for battery-powered sensor nodes, remote controls, and portable instrumentation where multi-year operation is required.
Is the R5F104LDAFA#V0 pin-compatible with other RL78/G14 variants in the same package?
Yes, the R5F104LDAFA#V0 is pin-compatible with all other RL78/G14 devices in the 64-pin LQFP (0.65 mm pitch) package, including R5F104LEAFA#V0 and R5F104LGAFA#V0. Pin functions, power domains, and peripheral mappings are identical - only flash/RAM capacities differ. This allows scalable design reuse and firmware portability across memory grades without PCB revision.
