Product details
Overview
R5F104GEANA#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G14 microcontroller with 48 KB flash, 5.5 KB RAM, and 4 KB data flash, operating at 1.6–5.5 V and delivering 44 DMIPS at 32 MHz for low-power industrial control applications including motor drive supervision and sensor-based HVAC monitoring.
For engineers reviewing the R5F104GEANA#V0 datasheet, R5F104GEANA#V0 pinout, R5F104GEANA#V0 application, or R5F104GEANA#V0 equivalent, key selection criteria include its 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) package, -40 to +85°C industrial temperature grade (D), integrated RTC with calendar support, 10-bit 20-channel ADC, and dual UART/LIN interfaces for embedded communication subsystems.
Technical Context
The R5F104GEANA#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) supporting chain transfer and background operation during data flash rewriting.
Peripheral integration includes Timer Array Unit (TAU) with up to 8 channels, Real-time Clock with alarm/calendar functions, and Event Link Controller (ELC) enabling hardware-triggered peripheral linking without CPU intervention - critical for deterministic real-time response in safety-aware systems.
