Connectivity covers CANbus, I²C, SCI, and SPI — sufficient for industrial sensor nodes or actuator control loops where CAN and serial links share the same MCU. The analog front-end provides 18 channels of 12-bit ADC and two channels of 8-bit DAC, letting the MCU sample multiple sensor inputs and output a control voltage without external converters. ## Package and board-fit Housed in an 80-LFQFP (12x12 mm) package with 69 I/O lines, the MCU requires a standard surface-mount footprint. The 0.50 mm pitch on the LFQFP demands a 4-layer board for full fan-out; two-layer designs can route the outer rows but may struggle with the inner signal escape.","metaTitle":"R5F51406AGFN#30 Renesas RX140 MCU, 48MHz, 256KB Flash","metaDescription":"R5F51406AGFN#30 RX140 32-bit MCU, 48MHz RXv2 core, 256KB flash, 64KB RAM, 8KB EEPROM, -40 to 105°C, 80-LQFP.
