The 48 MHz clock, combined with the DMA controller, handles sensor fusion loops and communication protocol stacks (CAN, I²C, SCI, SPI) without stalling the core on each byte transfer. ## Industrial temperature range and wide supply — where it goes on the board The 39 available I/O include capacitive touch channels, PWM outputs, and a 12-bit ADC with 11 multiplexed inputs — enough for a control panel with a touch interface, a few analog sensors, and a CAN bus to the host controller. ## Active lifecycle — no end-of-life clock ticking R5F51406ADNE#30 carries an active product status. The ROHS3 compliance is confirmed.","metaTitle":"R5F51406ADNE#30 Renesas RX140 32-bit MCU, 48 MHz","metaDescription":"Renesas R5F51406ADNE#30 RX140 32-bit MCU with RXv2 core at 48 MHz, 256 KB Flash, 64 KB RAM, 8 KB EEPROM.

The R5F51406ADNE#30 is part of the RX140 series with the same RXv2 core at 48 MHz. Firmware written for other RX140 variants is binary-compatible at the instruction-set level, though peripheral and pin-mapping differences (39 I/O vs 53 I/O on the R5F51406AGFM#30) require a review of the BSP and pin configuration files."},{"question":"What is the closest functional equivalent to R5F51406ADNE#30?","answer":"The R5F51406AGFM#30 is the same RX140 series, same 48 MHz RXv2 core, same 256 KB Flash, and same peripheral set (CAN, I²C, SCI, SPI, capacitive touch, DMA, PWM). The package differs — R5F51406AGFM#30 comes in a Tray, not the 48-WFQFN.
