8 位 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。体积小巧，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 工作 ATtiny43U ### AVR 微控制器，Atmel

The is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 512B EEPROM, 12 general purpose I/O lines, 32 general purpose working registers, an 2 timers/counters 8-bit/16-bit with two PWM channels each, internal and external interrupts, 8-channel 10-bit A/D converter, programmable gain stage 1x, 20x for 12 differential ADC channel pairs, programmable watchdog timer with internal oscillator, internal calibrated oscillator and four software selectable power saving modes. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processor speed.
