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
– 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
– 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
