STM32F103C8T6 by STMicroelectronics is a 32-bit microcontroller with 48 terminals, operating at up to 16 MHz. It features 10-Ch 12-Bit ADC channels and 7 DMA channels, suitable for industrial applications requiring low power consumption and high-speed connectivity via CAN, I2C(2), SPI(2), USART(3), USB.
Vishay Sprague's ULN-2803A is an 8-bit peripheral driver with a max supply voltage of 3V. Featuring open-collector output characteristics, it offers built-in transient protections and operates b/w -20°C to 85°C. Ideal for applications requiring sink current flow direction, this rectangular-shaped driver has a terminal pitch of 2.54mm and turn-on/off time of 1us.
LAN8720A-CP-TR by Microchip: Ethernet transceiver with 100 Mbps data rate, operates at 3.3V, and consumes 54mA max supply current. Ideal for network interfaces in commercial applications due to its small size (4x4mm) and low power consumption.
