ATtiny45 Microcontroller AVR – 8-Pin 4KB Flash 8-Bit MCU DIP/SOIC in Pakistan

Overview 

The ATtiny45 delivers high-performance 8-bit AVR computing into a tiny 8-pin DIP package. Equipped with 4KB of self-programmable Flash program memory, 256 bytes of SRAM, and 256 bytes of EEPROM, it provides ample resources for straightforward firmware logic, custom sensor nodes, and LED lighting controllers. Its internal precision oscillator and low-power architecture make it a reliable drop-in alternative for space-sensitive designs.

Key Features 

• Ultra-Compact 8-Pin Footprint: Pin-compatible with the ATtiny85, ideal for seamless layout reuse in wearable electronics and mini breakout boards.

• Self-Programmable Flash Memory: 4KB of ISP Flash memory supports multiple firmware rewrites during development.

• Internal Precision Oscillator: Operates internally up to 8 MHz or 16 MHz, reducing external crystal component requirements.

• Analog and PWM Support: Features a multi-channel 10-bit Analog-to-Digital Converter (ADC) and high-speed PWM output channels.

• Power-Saving Modes: Built with power-down, idle, and standby modes optimized for battery-operated hardware.
