ATmega1284

8-bit AVR Microcontrollers ATmega1284 DATASHEET COMPLETE Introduction The Atmel® ATmega1284 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 ATmega1284 achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed. Feature High Performance, Low Power Atmel®AVR® 8-Bit Microcontroller Family Advanced RISC Architecture – 131 Powerful Instructions – Most Single Clock Cycle Execution – 32 x 8 General Purpose Working Registers – Fully Static Operation – Up to 20 MIPS Throughput at 20MHz – On-chip 2-cycle Multiplier High Endurance Non-volatile Memory Segments – 128KBytes of In-System Self-Programmable Flash Program Memory – 4KBytes EEPROM – 16KBytes 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 Atmel QTouch® Library Support – Capacitive Touch Buttons, Sliders and Wheels – QTouch and QMatrix acquisition – Up to 64 Sense Channels Atmel-42718B-ATmega1284_Datasheet_Complete-08/2016 JTAG (IEEE std. 1149.1 Compliant) Interface – Boundary-scan Capabilities According to the JTAG Standard – Extensive On-chip Debug Support – Programming of Flash, EEPROM,...
