ATMEGA64A-AU

ATmega64A ATmega64A DATASHEET COMPLETE Introduction The Atmel ATmega64A 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 ATmega64A achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed. Features High-performance, Low-power Atmel AVR 8-bit Microcontroller Advanced RISC Architecture 130 Powerful Instructions - Most Single-clock Cycle Execution 32 8 General Purpose Working Registers + Peripheral Control Registers Fully Static Operation Up to 16MIPS Throughput at 16MHz On-chip 2-cycle Multiplier High Endurance Non-volatile Memory segments 64Kbytes of In-System Self-programmable Flash program memory 2Kbytes EEPROM 4Kbytes Internal SRAM Write/Erase cycles: 10,000 Flash/100,000 EEPROM (1) Data retention: 20 years at 85C/100 years at 25C Optional Boot Code Section with Independent Lock Bits In-System Programming by On-chip Boot Program True Read-While-Write Operation Up to 64 Kbytes Optional External Memory Space Programming Lock for Software Security SPI Interface for In-System Programming JTAG (IEEE std. 1149.1 Compliant) Interface Boundary-scan Capabilities According to the JTAG Standard Extensive On-chip Debug Support Atmel-8160E-ATmega64A Datasheet Complete-09/2015 Programming of Flash, EEPROM, Fuses and Lock Bits through the JTAG Interface Atmel QTouch library support Capacitive touch buttons, sliders and wheels Atmel QTouch and QMatrix acquisition Up to 64 sense channels Peripheral Features Two 8-bit Timer/Counters with Separate Prescalers and Compare Modes Two Expanded 16-bit Timer/Counters with Separate Prescaler, Compare Mode and Capture Mode Real Time Counter with Separate Oscillator Two 8-bit PWM Channels 6 PWM Channels with Programmable Resolution from 1 to 16 Bits Output Compare Modulator 8-channel, 10-bit ADC 8 Single-ended Channels 7 Differential Channels 2 Differential Channels with Programmable Gain at 1x, 10x, or 200x Byte-oriented Two-wire Serial Interface Dual Programmable Serial USARTs Master/Slave SPI Serial Interface Programmable Watchdog Timer with On-chip Oscillator On-chip Analog Comparator Special Microcontroller Features Power-on Reset and Programmable Brown-out Detection Internal Calibrated RC Oscillator External and Internal Interrupt Sources Six Sleep Modes: Idle, ADC Noise Reduction, Power-save, Power-down, Standby, and Extended Standby Software Selectable Clock Frequency ATmega103 Compatibility Mode Selected by a Fuse Global Pull-up Disable I/O and Packages 53 Programmable I/O Lines 64-lead TQFP and 64-pad QFN/MLF Operating Voltages 2.7 - 5.5V Speed Grades 0 - 16MHz Atmel ATmega64A DATASHEET 2 Atmel-8160E-ATmega64A Datasheet Complete-09/2015
