Product details
ATtiny85 8-Bit tinyAVR Microcontrollers
The Atmel ATtiny85 Microcontroller is an 8-bit device based on the AVR enhanced RISC architecture. Being an Atmel tinyAVR device the ATtiny85 is packs performance and power efficiency into a small package, perfect for applications where space is at a premium. By executing powerful instructions in a single clock cycle the ATtiny85 achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and speed.

20 MHz Max. Operating Frequency
8 KB Flash
512 Bytes EEPROM
0.5 KB SRAM
120 Instructions – Most single clock cycle execution
32 General Purpose Registers
6 GPIO
debugWIRE On-chip Debug System
In-System Programmable via SPI Port
External and Internal Interrupt Sources
Low Power Idle, ADC Noise Reduction, and Power-down Modes
Enhanced Power-on Reset Circuit
