Product details
Overview
R5F104LDAFA#10 from Renesas is a 64-pin LQFP-0.65mm-pitch, industrial-grade (D-grade, −40°C to +85°C) 16-bit RL78/G14 microcontroller with 128 KB flash, 8 KB data flash, and 16 KB RAM. It delivers 44 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 12-bit ADC (12 channels), RTC, and hardware DTC/ELC for embedded control in space-constrained industrial sensors and motor drives.
For engineers reviewing the R5F104LDAFA#10 datasheet, R5F104LDAFA#10 pinout, R5F104LDAFA#10 application, or R5F104LDAFA#10 equivalent, key selection considerations include its 64-pin LQFP-0.65 mm package, 128 KB/8 KB/16 KB memory configuration, industrial temperature rating, integrated analog peripherals (ADC/DAC/comparator), and support for low-power SNOOZE/HALT/STOP modes in battery-backed or energy-sensitive designs.
Technical Context
The R5F104LDAFA#10 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 on-chip debug, self-programming with boot swapping, and background data flash rewriting (BGO) at VDD = 1.8–5.5 V.
Its peripheral set includes Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, calendar RTC with alarm/correction, watchdog timer, and Event Link Controller (ELC) enabling direct hardware-triggered peripheral chaining without CPU intervention-critical for deterministic real-time response in motor control and industrial automation.
