16-bit RL78 core with 512 KB flash — memory headroom for code and data
The R5F100MLDFA#30 packs 512 KB of on-chip flash program memory (512K x 8) and 32 KB of RAM (32K x 8), plus a separate 8 KB EEPROM block for non-volatile parameter storage — enough to hold a moderate application stack, a real-time OS, and a data-logging buffer without external memory. The 16-bit RL78 CPU core runs at 32 MHz, giving a throughput ceiling that suits motor-control loops, sensor fusion, and HMI front-ends where the peripheral set — DMA, LVD, POR, PWM, WDT — handles real-time tasks without loading the core. Seventeen analog-input channels with 8- or 10-bit resolution let the MCU sample multiple sensors directly, reducing the need for an external multiplexer on a mixed-signal board.
80-LQFP package — standard footprint, MSL-aware reflow
The tray packaging suits both hand-assembly and automated pick-and-place.
Active lifecycle — no end-of-life pressure for new builds
Connectivity includes CSI (clocked serial interface), I²C, LINbus, and UART/USART — enough serial channels to talk to a CAN transceiver, an external ADC, or a display module without bit-banging GPIO.
