ATTINY261

In Production

The high-performance, low-power Microchip 8-bit AVR® RISC-based microcontroller combines 2 KB of ISP Flash memory, 128B ISP EEPROM, 128B internal SRAM, one 8/16-bit timer/counter with prescaler, one 8/10-bit high-speed timer/counter with PWM and separate prescaler, 10-bit A/D converter, a USI (Universal serial interface), and debugWIRE for on-chip debugging. The device supports a throughput of 16 MIPS at 16 MHz and operates between 2.7-5.5 volts. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed....

Description

The high-performance, low-power Microchip 8-bit AVR® RISC-based microcontroller combines 2 KB of ISP Flash memory, 128B ISP EEPROM, 128B internal SRAM, one 8/16-bit timer/counter with prescaler, one 8/10-bit high-speed timer/counter with PWM and separate prescaler, 10-bit A/D converter, a USI (Universal serial interface), and debugWIRE for on-chip debugging. The device supports a throughput of 16 MIPS at 16 MHz and operates between 2.7-5.5 volts.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
