ATTINY861A-PU Description

Short technical summary and product information.

The ATTINY861A-PU is an 8-bit AVR microcontroller from Microchip Technology. It features 8KB of in-system programmable Flash memory, 512 bytes of SRAM, and 512 bytes of EEPROM, with endurance of 10,000 and 100,000 write/erase cycles respectively. The device operates at clock speeds up to 20 MHz and supports a supply voltage range of 1.8V to 5.5V.

 

The microcontroller includes a 10-bit ADC with 11 single-ended channels, a Universal Serial Interface (USI), multiple PWM outputs, a programmable watchdog timer, and an on-chip temperature sensor. It also offers brown-out detection and power-on reset, along with four sleep modes for low-power operation.

 

The ATTINY861A-PU is available in a 20-pin PDIP (0.300" wide) through-hole package, suitable for breadboards and prototyping. With 16 programmable I/O lines, it can interface with a variety of external components and sensors.
