The ATTINY20-EK1 is an touch demo kit based on Tiny20 device. Tiny20 is 8bit AVR microcontroller with 2KBytes ISP flash. The ATtiny20 AVR is supported by a suite of program and system development tools, including macro assemblers and evaluation kits. Tiny20 is High performance, low power Atmel 8bit AVR RISC based microcontroller combines 2KB ISP flash memory, 128B SRAM, twelve general purpose I/O lines, 16 general purpose working registers, an 8bit timer/counter with two PWM channels, a 16bit timer/counter with two PWM channels, internal and external interrupts, an 8 channel 10bit A/D converter, programmable watchdog timer with internal oscillator, a slave two-wire interface, a master/slave serial peripheral interface, an internal calibrated oscillator, and four software selectable power saving modes.
