ATtiny 系列单片机介绍：

爱特梅尔公司 (Atmel Corporation) 宣布其低功耗的ATtiny 10/20/40微控制器 (MCU) 系列，针对按键、滑块和滑轮等触控感应应用予以优化。这些器件包括了AVR MCU 及其专利的低功耗 picoPower技术，是对成本敏感的工业和消费电子市场上多种应用，如汽车控制板、LCD电视和显示器、笔记本电脑、手机等的理想选择。

ATtiny MCU系列介绍

爱特梅尔 ATtiny 新型单片机集成有爱特梅尔的AVR 微控制器，以及包括1KB至4KB 的闪存，带有32 KB至256 KB 的SRAM。

此外，这些器件支持 SPI 和TWI (具备I2C-兼容性) 通信，提供高灵活性和1.8V至5.5V的工作电压

。ATtinyAVR使用爱特梅尔专利的 picoPower技术，耗电极低。通过软件控制系统时钟频率，取得系统性能与耗电之间的佳平衡，同时也得到了广泛应用。

Digispark USB Development Board

The Digispark is an Attiny85 based microcontroller development board similar to the Arduino line, only cheaper, smaller, and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE the Digispark is a great way to jump into electronics, or perfect for when an Arduino is too big or too much.

The Digispark is shipped fully assembled except for the two included and easy to solder headers.

Here are the specs:

Support for the Arduino IDE 1.0+ (OSX/Win/Linux)
Power via USB or External Source - 5v or 7-35v (12v or less recommended, automatic selection)
On-board 500ma 5V Regulator
Built-in USB
6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB)
8k Flash Memory (about 6k after bootloader)
I2C and SPI (vis USI)
PWM on 3 pins (more possible with Software PWM)
ADC on 4 pins
Power LED and Test/Status LED
