The ATmega16A 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 ATmega16A 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 131Powerful Instructions – Most Single-clock Cycle Execution 32x 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 16K Bytes of In-System Self-programmable Flash program memory 512Bytes EEPROM 1K Byte Internal SRAM 1K 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. 1149.1 Compliant) Interface Boundary-scan Capabilities According to the JTAG Standard Extensive On-chip Debug Support Programming of Flash, EEPROM, Fuses, ...
