ATTINY1634-MNR

The ATTINY1634-MNR is an 8-bit RISC microcontroller from Atmel, part of the ATtiny family. It features 16KB of Flash program memory, 1KB of SRAM, and 256 bytes of EEPROM, providing ample storage for embedded applications. The device operates at a clock frequency of up to 12 MHz and supports a supply voltage range of 1.8V to 5.5V (with a nominal 5V operation per manufacturer page). It includes 18 general-purpose I/O lines and a variety of peripherals such as I²C, SPI, UART/USART, and USI connectivity, as well as PWM channels, an ADC with 12 channels at 10-bit resolution, and built-in brown-out detection, power-on reset, and watchdog timer.

The microcontroller is designed for surface-mount assembly in a 20-WFQFN exposed pad package (20-QFN-EP, 4x4 mm) with a 0.50 mm pitch and 0.80 mm height. It is rated for industrial temperature range from -40°C to 105°C, making it suitable for harsh environments. The device is RoHS3 compliant and lead-free.

With its rich set of peripherals and low-power capabilities, the ATTINY1634-MNR is well-suited for a wide range of embedded control applications, including sensor interfaces, motor control, and communication modules. Its compact footprint and robust feature set make it a versatile choice for space-constrained designs.
