The Microchip ATTINY44V-10SSUR: A Compact Powerhouse for Embedded Designs

In the vast ecosystem of microcontrollers, the 8-bit AVR architecture from Microchip remains a cornerstone for countless embedded systems, prized for its simplicity, efficiency, and robust development tools. The ATTINY44V-10SSUR stands as a prime example of this enduring legacy, packing a surprising amount of functionality into a minimal footprint. This device is engineered for applications where low power consumption, cost-effectiveness, and a small form factor are paramount.

Housed in a 14-pin SSOP package, this microcontroller is designed for space-constrained PCB layouts. Despite its compact size, it features a powerful core capable of executing instructions at up to 10 MIPS at 10MHz. A key attribute of the ‘V’ variant is its capability to operate at an exceptionally low voltage, from 1.8V to 5.5V, making it ideal for battery-powered and energy-harvesting applications where maximizing operational life is critical.

The integrated peripherals on the ATTINY44V are thoughtfully selected for a wide range of control tasks. It boasts 12 programmable I/O lines, offering immense flexibility for interfacing with sensors, actuators, and communication modules. A built-in 10-bit ADC (Analog-to-Digital Converter) with 8 channels allows for precise measurement of analog signals, which is essential for environmental monitoring and data acquisition systems. Furthermore, it includes versatile serial interfaces: a Universal Serial Interface (USI) that can be configured for I2C or SPI protocols, facilitating easy communication with other chips.

For timing and control applications, it is equipped with two timers/counters (one 8-bit and one 16-bit) with PWM support, enabling functions like motor control or precise signal generation. The on-chip internal oscillator runs at 8MHz, reducing external component count and simplifying design while saving board space and cost.

Development is supported by the comprehensive Atmel Studio (now Microchip Studio) and the widespread AVR-GCC toolchain, allowing engineers to quickly prototype and deploy code. Its combination of low-voltage operation, a rich feature set, and a tiny package makes the ATTINY44V-10SSUR a superior choice for designing products like wearable electronics, smart sensors, small motor controllers, and DIY maker projects.

ICGOODFIND: The Microchip ATTINY44V-10SSUR is a highly integrated, low-voltage AVR microcontroller that delivers a potent blend of processing capability, peripheral integration, and power efficiency in a minimal SSOP-14 package, making it an optimal solution for compact and portable embedded designs.
