Atmel ATmega328 8-Bit AVR® MCUs

Atmel ATmega328 8-Bit AVR® MCUs

Atmel ATmega328 8-bit AVR® microcontrollers are high-performance RISC-based devices that combine 32KB ISP Flash memory with read-while-write capabilities, 1KB EEPROM, 2KB SRAM, 23 general-purpose I/O lines, 32 general-purpose working registers, serial programmable USART, and more. Atmel ATmega328 MCUs execute powerful instructions in a single clock cycle, allowing the device to achieve throughputs approaching 1 MIPS per MHz while balancing power consumption and processing speed. These Atmel MCUs are designed for use in industrial automation and home and building automation.

Atmel ATmega328 Development Tools

Atmel offers a variety of development tools for debugging and device programming. The AVR Dragon is an In-System Debugger for Atmel 8-bit and 32-bit AVR Microcontrollers with with On Chip Debug (OCD) capability. It can perform a symbolic debug on all devices with OCD with SPI, JTAG, PDI (selected devices), high voltage serial programming, parallel programming, and aWire modes, and supports debugging using SPI, JTAG, PDI interfaces. A development area lets designers build their own circuitry or add sockets for the desired device footprint. The JTAGICE 2 and JTAGICE 3 are mid-range development tools for Atmel 8-bit and 32-bit AVR devices with on-chip debugging for source level symbolic debugging, NanoTrace (if supported by the device), and device programming. The AVR ONE! supports the complete development cycle and is the fastest debugging tool offered from Atmel.
