It packs 128 KB of program flash, 32 KB of SRAM, and 8 KB of on-chip EEPROM — enough headroom to run a capacitive-touch HMI alongside a CANbus fieldbus stack without external memory. ## 53 I/O, 15-ch ADC, CANbus — peripheral fit for a sensor hub or motor-control node The connectivity set includes CANbus, I²C, SCI (UART), and SPI — enough to talk to a VFD over CANopen, poll a temperature sensor over I²C, and log data over a serial link. On-chip peripherals include AES encryption, a true random number generator (TRNG), capacitive touch sensing, DMA, and a watchdog timer — the AES+TRNG combo is useful for secure firmware update or authentication in an IoT edge node.","metaTitle":"R5F51405BGFM#30 Renesas RX140 MCU, 48 MHz, 128 KB Flash","metaDescription":"R5F51405BGFM#30 Renesas RX140 32-bit MCU, 48 MHz RXv2 core, 128 KB flash, 32 KB RAM, 8 KB EEPROM, 53 I/O, 64-LQFP.
