ATmega32U4 8-bit Microcontroller (TQFP-44) – SMD


Out of stock


The low-power Microchip 8-bit AVR® RISC-based microcontroller featuring 32 KB self-programming flash program memory, 2.5 KB SRAM, 1 KB EEPROM, USB 2.0 full-speed/low-speed device, 12-channel 10-bit A/D-converter, and JTAG interface for on-chip-debug. The device achieves up to 16 MIPS throughput at 16 MHz. 2.7-5.5 volt operation.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, allowing you to optimize power consumption versus processing speed.
