Overview
Atmel® offers both 8-bit and 32-bit AVRs.
AVR microcontrollers and application processors deliver unmatched flexibility. AVR combines the most code-efficient
architecture for C and assembly programming with the ability to tune system parameters throughout the entire life
cycle of your key products. Not only do you get to market faster, but once there, you can easily and cost-effectively
refine and improve your product offering.
It’s simple: AVR works across the entire range of applications you’re working on... or want to work on.
32-bit AVR UC3
The 32-bit AVR UC3 product family is built on the high performance 32-bit AVR architecture and optimized for highly
integrated applications. The 32-bit AVR UC3 microcontrollers deliver high computational throughput, deterministic real-time
control, low power consumption, low system cost, high reliability and ease of use. The 32-bit AVR CPU includes cutting
edge features such as integer and fixed point DSP arithmetic, single-cycle multiply and accumulate instructions, and
single-cycle SRAM access. The peripheral DMA controller and multi-layer high speed bus architecture make the UC3 core
ideal for high throughput applications. UC3 devices are perfectly suited for portable and battery-powered applications
due to their outstanding low power properties.
8/16-bit AVR XMEGA
The AVR XMEGA gives you 16-bit performance and leading low-power features at 8-bit price. With a Peripheral DMA
controller, an innovative Peripheral Event System, crypto engine, and high speed ADC and DAC, AVR XMEGA pushes the
boundaries for high performance 8/16-bit MCUs.
All AVR XMEGA are compatible with tinyAVR and megaAVR devices. Within the XMEGA family, they are 100% code
compatible across all devices from the smallest to the largest. It is possible to development with any XMEGA device,
and switch to any other XMEGA device later without having to change any code. This allows multi-project development
teams to keep and maintain only one code base and use and re-use this across multiple projects. The result is a
much faster development and prototyping cycles.
8-bit megaAVR
When your designs call for a bit of extra muscle, you need megaAVR. Developed for applications that need to store
a large amount of program code, megaAVR offers substantial program and data memories, and performance approaching 1 MIPS
per MHz. Better yet, megaAVR delivers the power of self-programmability for fast, secure, cost-effective remote
upgrades.
8-bit tinyAVR
Don't let the name fool you... tinyAVR delivers huge capability. Optimized for a wide range of applications that
require a small but powerful MCU solution, tinyAVR requires no external glue logic, and is available with integrated
A/D converter and EEPROM memory.
By delivering Flash flexibility at Mask ROM prices, tinyAVR significantly cuts your time to market, while boosting
your bottom line. And there’s nothing tiny about that.
Battery Management
The single-chip AVR battery management products cover the 1 to 4 Li-ion cells market. They feature dedicated
analog-to-digital converters tailored for battery fuel gauging and voltage monitoring. Other MCU features include
independent battery protection circuitry, voltage regulators, integrated cell balancing FETs, and special high voltage
I/O controlling charge and discharge.
