It carries 256 KB of program Flash, 64 KB of SRAM, and 8 KB of data EEPROM — enough headroom for moderate control and sensor-fusion firmware without external memory. ## Peripheral set: AES, capacitive touch, CAN, and 15-channel 12-bit ADC On-chip peripherals include AES encryption, a true random number generator (TRNG), capacitive touch sensing, DMA, LVD, POR, PWM, a temperature sensor, and a watchdog timer. Connectivity covers CANbus, I²C, SCI (UART), and SPI. The data converter block provides 15 channels of 12-bit ADC and two channels of 8-bit DAC. For a 48 MHz MCU in this price tier, the integrated security and touch blocks reduce external BOM count for IoT edge nodes and HMI panels. ## Package and footprint: 64-LQFP, 10x10 mm body Housed in a 64-pin LQFP (also specified as 64-LFQFP with a 10x10 mm body), the R5F51406BDFM#30 exposes 53 I/O lines. The package is surface-mount, suitable for standard reflow profiles. For production planning, this part is qualified for new designs and dual-sourcing programs. The RX140 series is Renesas's current low-power 32-bit line, so roadmap continuity is solid through the next several years.","metaTitle":"R5F51406BDFM#30 RX140 32-Bit MCU, 48 MHz, 256 KB Flash","metaDescription":"R5F51406BDFM#30 Renesas RX140 32-bit MCU at 48 MHz with 256 KB Flash, 64 KB RAM, 8 KB EEPROM.
