ATTINY25-20MU

The ATTINY25-20MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features an advanced RISC architecture with 120 instructions, most executed in a single clock cycle, and 32 x 8 general-purpose working registers. The device offers 2KB of in-system programmable Flash memory with 10,000 write/erase cycles endurance, 128 bytes of SRAM, and 128 bytes of EEPROM with 100,000 write/erase cycles. Operating at speeds up to 20MHz, it supports a supply voltage range of 2.7V to 5.5V. Peripheral features include an 8-bit timer/counter with two PWM channels, an 8-bit high-speed timer/counter with two additional PWM outputs, a Universal Serial Interface (USI) with start condition detector, a 10-bit ADC with 4 single-ended channels, and programmable brown-out detection, power-on reset, and watchdog timer. The microcontroller also includes debugWIRE on-chip debugging and in-system programming via SPI.

The ATTINY25-20MU is housed in a 20-WFQFN exposed pad package (supplier device package 20-QFN-EP, 4x4mm) and is surface mount compatible. It operates over an industrial temperature range of -40°C to 85°C. With six programmable I/O lines, this MCU is suitable for compact embedded applications requiring low power consumption, such as sensor interfaces, battery management, and motor control.
