Product Description
Microchip ATTINY85-20MU is a highly efficient 8-bit AVR microcontroller in an 8-pin VQFN surface mount package with dimensions of 4mm length and width and 750μm height. It operates at a maximum speed of 20 MHz, powered by a voltage ranging from 2.7 V to 5.5 V, making it suitable for low-power embedded applications.
Featuring 8kB of FLASH program memory, 512 bits of internal SRAM, and 512 bytes EEPROM, this microcontroller ensures ample memory for complex embedded system development. It supports SPI interface for robust communication protocols and includes 6 programmable I/O lines for versatile hardware interfacing.
The device integrates advanced features such as a 4-channel 10-bit analog-to-digital converter (ADC), one 8-bit high-speed timer with separate prescaler, an 8-bit timer/counter with two PWM channels, one analogue comparator, and on-chip debugging via debug wire. It operates reliably over a wide thermal range from -40°C to 85°C.
This microcontroller offers fully static operation and power-saving modes including low power idle, ADC noise reduction, and power-down mode, optimizing power consumption for industrial, consumer appliance, and home automation applications. It supports power-on reset, programmable brown-out detection, window watchdog timer (WDT) with separate oscillator, and write/erase cycles rated at 10,000 for flash and 100,000 for EEPROM.
Operates at maximum clock frequency of 20 MHz. Contains 8kB of FLASH program memory. Equipped with 512 bits of RAM and 512 bytes EEPROM. Supports SPI interface for communication. Features 6 programmable I/O lines and 4-channel 10-bit ADC.
