ATMEL

The ATmega32A 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 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. | Features High-performance Low-power AVR 8-bit Microcontroller Advanced RISC Architecture - 131 Powerful Instructions - Most Single-clock Cycle Execution - 32 x 8 General Purpose Working Registers - Fully Static Operation - Up to 16 MIPS Throughput at 16 MHz - On-chip 2-cycle Multiplier High Endurance Non-volatile Memory segments - 32K Bytes of In-System Self-programmable Flash program memory - 1024 Bytes EEPROM - 2K Byte Internal SRAM - Write Erase Cycles 10 000 Flash 100 000 EEPROM - Data retention 20 years at 85 C 100 years at 25 C 1 - Optional Boot Code Section with Independent Lock Bits In-System Programming by On-chip Boot Program True Read-While-Write Operation - Programming Lock for Software Security JTAG IEEE std.
