MCU AVR 8BIT 32KB FLASH 20SOIC 20MHZ


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardATtiny3216 is an 8-bit AVR microcontroller with 32 KB Flash, 2 KB SRAM, and 256 bytes EEPROM, running up to 20 MHz. Features integrated analog (two 10-bit ADCs, three DACs, three comparators), multiple timers, USART, SPI, TWI, and Peripheral Touch Controller for capacitive sensing. Suitable for embedded control, IoT, sensor interfaces, and capacitive touch applications.
The 1.27mm pin pitch makes hand-soldering this 20-pin SOIC challenging and error-prone. A breakout board brings all pins to standard 0.1" spacing, enabling reliable breadboard prototyping and simplifying development of USB-to-UART interfaces without requiring reflow soldering or specialized equipment.
