The ATTINY43U-SUR is an 8-bit microcontroller from Microchip Technology's AVR® ATtiny series. It features a 4KB (2K x 16) Flash memory and operates at a maximum speed of 8MHz, housed in a 20-pin SOIC package. The microcontroller includes a 4-channel, 10-bit analog-to-digital converter (A/D) and a Universal Serial Interface (USI), making it capable of handling both analog and digital interfacing tasks. Furthermore, it offers an internal SRAM of 64 bytes (64 x 8), providing modest storage for operational data. This microcontroller is suitable for compact and simple embedded applications due to its small footprint and essential functionality.
