Overview
R5F104JDDFA#V0 from Renesas is a 52-pin LQFP-0.65mm industrial-grade RL78/G14 microcontroller with 48 KB flash, 4 KB data flash, 4 KB RAM, 10-bit ADC (16 channels), and integrated RTC/LVD. It operates from 1.6–5.5 V at -40 to +85°C and delivers 44 DMIPS at 32 MHz for sensor interface and motor control in factory automation systems.
For engineers reviewing the R5F104JDDFA#V0 datasheet, R5F104JDDFA#V0 pinout, R5F104JDDFA#V0 application, or R5F104JDDFA#V0 equivalent, key selection criteria include its 52-pin LQFP package, 48 KB code flash with self-programming, 16-channel 10-bit ADC, real-time clock with calendar function, and support for UART, I²C, and CSI serial interfaces in space-constrained industrial designs.
Technical Context
The R5F104JDDFA#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 integrates a Data Transfer Controller (DTC) for autonomous memory transfers and an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Power management includes HALT, STOP, and SNOOZE modes, achieving 66 μA/MHz active current and 0.60 μA RTC+LVD retention. Its on-chip high-speed oscillator supports 12 selectable frequencies (1–64 MHz) with ±1.0% accuracy across 1.8–5.5 V and -20 to +85°C.
