MICROCHIP ATtiny45-20PU 20MHz 8-bit AVR Microcontroller DIP-8

The MICROCHIP ATtiny45-20PU is a high-performance, low-power 8-bit AVR microcontroller, perfectly suited for compact embedded control applications. This device integrates 4KB of in-system programmable flash memory, 256 bytes of EEPROM, and 256 bytes of SRAM on a single chip, providing ample resources for your project's code and data storage needs. Manufactured using advanced high-density non-volatile memory technology, it offers reliable and flexible programming options.

A standout feature is the on-chip ISP (In-System Programmable) flash, which allows you to reprogram the memory directly on your board via an SPI serial interface. This can be done using a standard programmer or via the on-chip boot code, streamlining the development and update process significantly.
