8 位 PicoPower tinyAVR® 微控制器，AtmelAtmel 的 tinyAVR® 设备经优化处理，适用于需要性能、电源效率、易于使用且采用小型封装的应用。 所有 picoPower 设备均经过重新设计，旨在提供最低的功耗。最紧凑的小型封装，适用于注重尺寸的应用 电容式触摸 快速，且代码高效 高集成 1.8V 至 5.5V 操作（0.7V 操作，用于 ATtiny43U） ### AVR 微控制器，Atmel

The is a 8-bit high-performance picoPower AVR RISC-based Microcontroller combines 16kB flash memory, 256B EEPROM, 1kB SRAM, 18 general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter, one 16-bit timer/counter, two full duplex USARTs with start frame detection, a universal serial interface USI, I²C slave, internal and external interrupts, an 12-channel 10-bit A/D converter, programmable watchdog timer with ultra low power internal oscillator and four software selectable power saving modes. The device operates between 1.8 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
