ATTINY441-MMH

ATMEL  ATTINY441-MMH  微控制器, 8位, 低功率高性能, ATtiny, 16 MHz, 4 KB, 256 Byte, 20 引脚, VQFN

The is a low-power 8-bit CMOS Microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny441 achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All 32 registers are directly connected to the arithmetic logic unit ALU, allowing two independent registers to be accessed in a single instruction, executed in one clock cycle. The resulting architecture is compact and code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The ATtiny441 provides 4kB of in-system programmable flash, 256byte of SRAM and 256byte of EEPROM data memory.
