Microchip Technology ATtiny AVR 8位微控制器

Microchip Technology ATtiny AVR^® 8位微控制器 (MCU) 经过优化用于需要高性能、功率效率和易于使用的应用，采用小型封装。ATtiny417/ATtiny814/ATtiny816/ATtiny817 MCU设有一个8位AVR处理器，硬件乘法器运行速率高达20MHz，闪存高达8KB，SRAM为512字节，EEPROM为128字节，采用14引脚、20引脚和24引脚封装。这些器件采用Atmel picoPower^®技术实现灵活的低功耗架构，包括Event System和SleepWalking、准确模拟功能和高级外设。带驱动扩展板的电容式触摸界面由集成的QTouch^® 外围触摸控制器支持。内核独立外设(CIP)技术允许连接的外设独立于内核运行，并包含串行通信和模拟外设。Event System允许外设在不使用CPU的情况下进行通信，可以在系统级优化应用。这降低了功耗并提高了吞吐量和系统可靠性。

Core Independent Peripherals (CIPs) technology allows connected peripherals to operate independently of the core and includes serial communication and analog peripherals. Together with the Event System, which allows peripherals to communicate without using the CPU, applications can be optimized at a system level. This lowers power consumption and increases throughput and system reliability.
