Embedded - Microcontrollers

The ATTINY25GAL-15MZ is a versatile 8-bit microcontroller from the ATTINY family of Atmel. It is designed to be used in small and battery powered applications, including portable medical, automotive infotainment and industrial sensors. The ATTINY25GAL-15MZ is a low power and low cost microcontroller, which makes it suitable for embedded applications.

Main features and specifications

The ATTINY25GAL-15MZ is a 8-bit microcontroller with a low power Energy Star TM certified wireless technology and low cost ARM Cortex-M0+ core processor. It operates at 16MHz clock frequency and has eight I/O pins, two channels of UART, two channels of I2C, one 8-bit timer and one 8-bit counter. It also has a 4kbyte Flash memory, 16-bit wide ROM, a watchdog timer and two serial programmable interfaces for supporting various communication protocols. It also provides two 16-bit timers, two analog-to-digital converters, a 12-bit resolution ADC, a digital-to-analog converter, an I2C bus master and an SPI bus.

Applications and Working Principle

The ATTINY25GAL-15MZ is suitable for portable and embedded systems due to its low power consumption and low cost. Many small and battery operated applications, such as digital watches, medical devices and automotive infotainment systems use this microcontroller. Additionally, it can be used in industrial sensors and automation systems.

The ATTINY25GAL-15MZ uses a Harvard Architecture which allows data to be stored separately from the program counter in a memory space. This allows it to process instructions faster and run multiple tasks at one time. The microcontroller supports two serial programmable interfaces, SPI and I2C. It also provides a 3-bit timer and a 12-bit resolution ADC for data conversion. Moreover, the ATTINY25GAL-15MZ is built with power-saving features like the Brown Out Reset (BOR) which helps thus microcontroller to take less power from the source when the power level is low.

Conclusion

In conclusion, the ATTINY25GAL-15MZ is a low cost and low power microcontroller that is suitable for embedded and portable systems. It offers features like low power consumption and multiple serial interfaces, making it well suited for applications in consumer electronics, medical devices and industrial automation.
