Its 64 KB on-chip flash provides enough firmware space for a full application stack with a small RTOS, while the 5.5 KB RAM handles moderate data buffering and stack depth — adequate for control loops and serial communication but tight for heavy graphics or large lookup tables. ## Peripheral set and I/O count 25 general-purpose I/O pins in a 32-LQFP package — the I/O count is the limiting factor for peripheral expansion. On-chip peripherals include LVD, POR, PWM, and WDT, reducing external supervisory and timing components. The connectivity suite covers CSI, I²C, LINbus, and UART/USART, supporting common serial buses and automotive LIN. Data conversion comes from an 8-channel 10-bit ADC and a 2-channel 8-bit DAC, sufficient for basic sensor acquisition and analog output. ## Package and board integration Surface-mount mounting with a standard 0.8 mm pitch keeps the layout straightforward. The tray packaging is typical for production quantities; reels are available through the supply chain.","metaTitle":"R5F104BEGFP#10 Renesas RL78/G14 MCU, 32 MHz, 64 KB Flash","metaDescription":"R5F104BEGFP#10 Renesas RL78/G14 16-bit MCU: 32 MHz core, 64 KB flash, 5.5 KB RAM, 2.4-5.5 V supply, -40 to +105°C.
