Microchip Technology ATTINY3216-SNR

The ATTINY3216-SNR is a versatile and powerful microcontroller from Microchip Technology, designed for applications that require a compact footprint without compromising on performance. As part of the tinyAVR® 1-series, this microcontroller integrates an 8-bit high-performance AVR® RISC CPU with a wealth of features that make it ideal for a wide range of embedded systems.

At the heart of the ATTINY3216-SNR lies a robust architecture that operates at a maximum frequency of 20MHz. With 32KB of in-system self-programmable flash memory, 256B EEPROM, and 2KB SRAM, it offers ample space for complex applications. The device supports a wide voltage range of 1.8V to 5.5V, ensuring flexibility in various operating environments and making it suitable for battery-operated and portable applications.

This microcontroller boasts a rich set of peripherals that include a 12-channel, 10-bit Analog-to-Digital Converter (ADC) with a differential input and programmable gain amplifier, enabling precise sensor signal acquisition. The unit also features a 10-bit Digital-to-Analog Converter (DAC) for analog output capabilities. For timing-sensitive operations, the ATTINY3216-SNR is equipped with two 16-bit Timer/Counters and a 12-bit Timer/Counter with PWM channels.

Communication with other devices is facilitated by the inclusion of a Universal Serial Interface (USI), SPI, and I2C, allowing for easy integration into larger systems. Additionally, the device supports a Configurable Custom Logic (CCL) subsystem, which provides users with the ability to create simple logic functions internally, reducing external component count and saving board space.

To ensure reliable operation, the ATTINY3216-SNR includes safety features such as a Power-on Reset, a Brown-out Detector, and a Watchdog Timer. It is available in a compact 20-pin SOIC package, making it suitable for space-constrained applications.

Whether you're designing consumer electronics, IoT devices, or industrial control systems, the Microchip Technology ATTINY3216-SNR provides a perfect balance of size, performance, and power efficiency, making it an excellent choice for your next project.
