ATTINY261A-PU

The ATTINY261A-PU is an 8-bit AVR microcontroller from Microchip Technology, part of the ATtiny family. It features a high-performance RISC architecture with 123 instructions, most executed in a single clock cycle. The device includes 2KB of in-system self-programmable Flash memory, 128B of SRAM, and 128B of EEPROM, all with high endurance: 10,000 write/erase cycles for Flash and 100,000 for EEPROM.

This microcontroller operates at supply voltages from 1.8V to 5.5V, with speed grades of 0-4 MHz at 1.8-5.5V, 0-10 MHz at 2.7-5.5V, and 0-20 MHz at 4.5-5.5V, providing up to 20 MIPS throughput. It includes a 10-bit ADC with 11 single-ended channels and 16 differential pairs, an on-chip temperature sensor, two timer/counters, PWM outputs, a watchdog timer, and a USI for serial communication. Power consumption is low: 200 µA active at 1 MHz, 1.8V, and 0.1 µA in power-down mode.

The ATTINY261A-PU is housed in a 20-pin PDIP (0.300-inch, 7.62mm) package with through-hole mounting. It offers 16 programmable I/O lines and supports debugWIRE on-chip debugging. The device is suitable for applications requiring low power, small footprint, and integrated analog features. Operating temperature range is -40°C to 85°C.
