The Microchip ATTINY24-20SSUR: A Compact Powerhouse for Embedded Designs
In the vast ecosystem of microcontrollers, the quest for a perfect balance of performance, size, and power efficiency is perpetual. The Microchip ATTINY24-20SSUR stands out as a quintessential solution, embodying the robust architecture of the AVR family within a remarkably small footprint. This 8-bit microcontroller is engineered for applications where space and power are at a premium, yet functionality cannot be compromised.
Housed in a compact 14-pin SOIC package, the ATTINY24-20SSUR is built around Microchip's advanced AVR RISC CPU core. Operating at a maximum frequency of 20 MHz, it delivers a formidable 20 MIPS throughput, enabling swift execution of control algorithms and real-time responses. This performance is complemented by its wide operating voltage range of 1.8V to 5.5V, making it exceptionally versatile for both battery-powered and line-operated devices.
A key strength of this microcontroller lies in its rich peripheral set, meticulously integrated to minimize external component count. It features 12 programmable I/O lines, each capable of sourcing or sinking significant current, directly interfacing with LEDs, buttons, and other digital sensors. For analog needs, it includes a 10-bit ADC (Analog-to-Digital Converter) with 11 channels, allowing for precise measurement of multiple analog signals. Furthermore, it incorporates versatile communication interfaces including SPI and I2C, facilitating seamless data exchange with a myriad of sensors, memories, and other peripherals.
The built-in hardware-based Touch Sensing capability is a standout feature, allowing for the implementation of robust touch interfaces without external dedicated chips. This is particularly valuable in modern consumer electronics and human-machine interfaces (HMI). For timing and control tasks, it is equipped with two timer/counters, one 8-bit and one 16-bit, offering PWM outputs for motor control or LED dimming.
Designed for resilience, the ATTINY24-20SSUR includes robust on-chip debug capability for accelerated system development and troubleshooting. Its enduring EEPROM data memory ensures data retention even when power is cycled, which is critical for storing calibration constants or user settings.
ICGOODFIND: The Microchip ATTINY24-20SSUR is a testament to highly integrated, efficient design. It packs a surprising amount of processing power and peripheral integration into a minimal form factor, making it an ideal choice for space-constrained, cost-sensitive, and power-aware applications such as wearable technology, advanced sensor nodes, home appliances, and industrial control systems.
