ATMEGA32A-PU

Product Summary

The ATMEGA32A-PU is an 8-bit microcontroller with 32k bytes in-system programmable flash. The ATMEGA32A-PU is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA32A-PU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.The ATMEGA32A-PU is supported with a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits.
