The ATtiny204-SSN 8-bit Microcontroller with MCU 20MHz, 2KB, SOIC14, Ind 105C, Green, Tray is a tiny, low-power CMOS 8-bit microcontroller that runs on a 20 MHz clock. It includes an industry-standard 8-bit AVR microcontroller core along with 2 KB of Flash program memory, 32 bytes of EEPROM, and 256 bytes of SRAM memory. The device is a low-power/low-voltage part with a many power saving modes that give low-power operation when idle. The operating voltage range is 1.8V to 5.5V and it has an operating temperature range of -40C to +105C. It also features an I/O count of 14 with 11 I/O pins to configure in Pin Change Interrupt or an Analog Comparator. The device is housed in a SOIC14 package and is available in green heavy-duty trays.
