Microchip Technology ATTINY25V-15ST Microcontroller

The ATTINY25V-15ST from Microchip Technology is a high-performance, low-power AVR® 8-bit microcontroller that combines 2KB ISP flash memory, 128B EEPROM, 128B SRAM, 6 general purpose I/O lines, 32 general purpose working registers, and more, all in a compact SOT-23-6 package. It operates within a voltage range of 1.8-5.5V, making it suitable for battery-operated and portable applications.

One of the notable features of the ATTINY25V-15ST is its versatility, which is enhanced by its various peripherals. It includes an 8-bit timer/counter with compare modes, an 8-bit high-speed timer, a USI (Universal Serial Interface), internal and external interrupts, a 4-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, three software selectable power saving modes, and debugWIRE for on-chip debugging.

The device supports a maximum clock frequency of 15MHz, allowing efficient processing and throughput. The combination of an advanced RISC architecture with well-thought-out instruction set enables the ATTINY25V-15ST to execute powerful instructions in a single clock cycle, thus achieving throughputs approaching 1 MIPS per MHz. This balance of performance and power consumption makes it ideal for a wide range of applications.

Programmability of the ATTINY25V-15ST is made simple through the ISP (In-System Programming) feature, which allows for programming and reprogramming of the microcontroller without removing it from the circuit. This convenience facilitates rapid development and iteration of designs, as well as updates and bug fixes to deployed systems.

As part of Microchip's tinyAVR® series, the ATTINY25V-15ST is designed with an emphasis on 'power per watt' and offers an array of power-saving modes. These features, along with its small footprint, make it an excellent choice for applications where space is at a premium and energy efficiency is crucial, such as wearable devices, sensors, and other embedded systems.

Overall, the ATTINY25V-15ST is a robust microcontroller that offers designers a great balance of power, flexibility, and convenience, wrapped up in a tiny, efficient package.
