ATTINY261A-MN [Microchip]

The Atmel ATtiny261/461/861 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 2/4/8K bytes of in-system programmable flash, 128/256/512 bytes EEPROM, 128/256/512 bytes SRAM, 16 programmable I/O lines, 32 general purpose working registers, multiple timers (8/16-bit and 8/10-bit high speed), 3 high frequency PWM outputs, universal serial interface, 10-bit ADC with 11 single-ended and 16 differential channels (15 with programmable gain), programmable watchdog timer, on-chip analog comparator, debugWIRE on-chip debug system, and three power saving modes. It operates from 2.7V to 5.5V with speeds up to 16MHz and is available in SOIC, TSSOP, and MLF packages.
