MCU 8BIT AVR 8KB FLASH 20SOIC 20MHZ


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom Board8-bit AVR microcontroller with 8 KB Flash, 512 bytes SRAM, and 128 bytes EEPROM, running at up to 20 MHz. Includes timers, UART, SPI, I2C, 10-bit ADC, DAC, and capacitive touch controller in a 20-pin SOIC package. Suitable for embedded control, sensor interfaces, and touch-enabled 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.
