It carries a 9-channel 8/10-bit ADC and a 2-channel 8-bit DAC, reducing the external analog bill of materials for sensor input and analog output loops. Serial connectivity covers CSI, I²C, LINbus, and UART/USART — enough for industrial fieldbus bridges, motor drive comms, or LIN subnets in automotive body electronics. The operating temperature range of -40°C to 85°C and a supply voltage span from 1.6 V to 5.5 V let it run on a single rail in unconditioned enclosures, factory floors, or outdoor telecom cabinets. The 40-HWQFN (6x6 mm) package with 28 I/O fits tight PCB layouts. ## On-chip analog and serial interfaces The 9-channel ADC (8- or 10-bit resolution) handles multiple analog sensor inputs — thermocouples, pressure transducers, current shunts — while the 2-channel DAC provides analog setpoints or signal conditioning outputs. The serial interface set (CSI, I²C, LINbus, UART/USART) covers the common protocols for industrial sensors, motor drives, and LIN-based automotive body modules. DMA, LVD, POR, PWM, and WDT peripherals are on board, reducing the need for external supervisor or timing ICs. ## Lifecycle and sourcing posture R5F104EFANA#20 carries an Active product status with ROHS3 compliance.","metaTitle":"R5F104EFANA#20 RL78/G14 16-bit MCU, 32 MHz, 96 KB Flash","metaDescription":"R5F104EFANA#20 from Renesas: 16-bit RL78 MCU at 32 MHz, 96 KB Flash, 12 KB RAM, 8 KB EEPROM, 28 I/O, -40 to 85°C, 1.6-5.5 V.
