Microchip ATTINY25-20SSN is a compact 8-bit AVR microcontroller designed for embedded and electronic applications that demand high performance and efficiency in a small form factor. This model features a 20 MHz maximum clock frequency, enabling rapid execution of instructions in time-sensitive environments. Its 2 kB FLASH program memory is suitable for storing firmware and operational logic, ideal for devices requiring low to moderate program sizes.
Housed in an 8-pin SOIC surface-mount package, ATTINY25-20SSN is easy to integrate within modern PCB layouts, offering reliability and space efficiency. With 6 programmable I/O pins, users can design flexible circuits for sensors, actuators, communication devices, or LED drivers. The microcontroller supports SPI interface, streamlining connectivity with peripheral modules and other microcontrollers for expanded functionality.
This device operates within a wide supply voltage range of 2.7 V to 5.5 V, making it compatible with various power sources in industrial, laboratory, and commercial settings. The built-in 128 bytes of RAM allow for efficient temporary storage and manipulation of data during operation, and the inclusion of 4 x 10-bit ADC channels supports precise analog signal sampling.
The ATTINY25-20SSN is engineered for durability and reliability, operating in harsh conditions from -40°C to 105°C, suitable for installations in demanding industrial electronics, instrumentation, and environmental monitoring systems. It employs RISC architecture for fast code execution, and features a single analogue comparator and timer, as well as capacitive touch support and high integration for space-constrained applications.
Common applications include industrial automation controls, laboratory instrumentation, robotics, sensor interfaces, portable and battery-powered devices, and custom embedded solutions. The device's RoHS compliance ensures it meets environmental and regulatory standards for modern electronic manufacturing.
