Microchip ATtiny45 20MHz 8-bit AVR Microcontroller DIP-8

Microchip ATtiny45 8-bit AVR Microcontroller offers a maximum operating frequency of 20MHz in a compact DIP-8 package, suited to space-constrained embedded control designs.

The Microchip ATtiny45 is a high-performance, low-power 8-bit AVR microcontroller designed for compact embedded control applications. It integrates 4KB of in-system programmable (ISP) flash memory, 256 bytes of EEPROM and 256 bytes of SRAM on a single chip, providing resources for application code and data storage.

The on-chip ISP flash can be reprogrammed directly on the board through an SPI serial interface. Programming can be carried out with a standard programmer or via the on-chip boot code, which streamlines the development and update process.
