System Performance

For embedded systems, system performance is much more than a good MIPS number. It is important to

have powerful, fast peripherals and an energy-efﬁcient memory system that allows the application to run

effortlessly with minimal power consumption.

Single Cycle SRAM

Fast SRAM access is critical to achieving the

necessary computing performance. The UC3 CPU

has a single-cycle access to the SRAM embedded

in the CPU itself.

Bus Matrix

To ensure sufﬁcient data bandwidth, the 32-bit AVR architects have designed a set of parallel buses where

each bus master has a dedicated bus for all the slaves. This gives the 32-bit AVR a tremendous data band-

width and removes the bottleneck encountered in traditional 32-bit microcontrollers.

Unrivalled DSP Performance

By including powerful instructions for single cycle multiply

accumulate and fractional multiply for various number

formats, the 32-bit AVR UC3 delivers unrivalled DSP per-

formance compared to legacy architectures. In the AVR

UC3 Software Framework more than 70 DSP functions

have been assembly optimized utilizing these instruc-

tions. DSP has never been easier.

Split Memory Architecture with

DMA

High performance peripheral modules require

a true memory DMA controller. In addition, the

memory is partitioned such that one memory block

resides inside the CPU to support single cycle

memory access during program execution. To maximize the bandwidth, two more SRAMs are placed on

two different layers on the multi-layered high-speed bus and can act as data buffers for high-speed periph-

erals like the USB. The SRAMs are coupled to the memory DMA controller such that data can be efﬁciently

moved without loading the CPU.

Code Density and Efﬁciency

The 32-bit AVR architecture was designed in close cooperation with compiler experts. This ensures that the

AVR architecture excels when compiling high-level programming languages like C and C++. Compact and

extended instructions are chosen by the compiler without any performance penalty introduced by legacy

architectures. A compact code is important, not only because it resolves in a smaller memory footprint, but

also because a dense instruction can easily be optimized for both speed and size.

page 7

www.atmel.com

Peripheral DMA Controller

The Atmel Peripheral DMA controller sets a

new standard for data transfer efﬁciency. If

the Peripheral DMA controller is not en-

abled, the maximum usable transfer rate on

the SPI module would be approximately 1

MBit/s, occupying the CPU with more than

50% load just moving data around. With the

Peripheral DMA controller this bottleneck is

removed and the AVR32 UC3 microcontroller

can achieve a transfer rate of 33 MBit/s on

SPI and USART with only a 15% load on the

CPU. The UC3 can even toggle the I/O pins

at 33 MHz.

Interrupt Controller

The 32-bit AVR UC3 CPU includes a multi-level interrupt

controller. Four priority levels are supported where higher

level interrupts are prioritized and executed before low level

interrupts. All peripherals can be assigned any interrupt level

and the interrupt vector addresses can be changed without

stopping the CPU. Interrupt latencies are very fast, typically

11 clock cycles including saving the register ﬁle to the stack.

A higher level interrupt will halt execution of a lower level interrupt routine. The lower level

interrupt routine will continue and ﬁnish after the higher level interrupt routine ﬁnishes.

A second interrupt at an interrupt level already being serviced, will pend until the ﬁrst

interrupt routine ﬁnishes.

Peripheral Event System

By removing interrupt-driven data transfer

and replacing it with an event-triggered

data transfer, the innovative Peripheral

Event System in 32-bit AVR UC3 repre-

sents a paradigm shift. The Peripheral

Event System allows the 32-bit AVR UC3

to send signals (events) directly to other

peripherals without involving the CPU. This

ensures short and predictable response

time, and at the same time it ofﬂoads the

CPU and reduces power consumption.

Without Peripheral Event System all Peripheral Requests

need to be handled by the CPU.

With Peripheral Event System peripherals can send

signals (events) to other peripherals.

Security

The 32-bit AVR UC3L provides mechanisms to protect

the system from hacker modiﬁcation,

ﬂash software theft and runaway code.

Secure CPU State

CPU resources and sections of code/data memory can be reserved for proprietary

software IP or critical sections of code/data. A special API is used to access

these resources from the rest of the code. Attempts to access these resources

by circumventing this API (either by hacking or runaway code) will be aborted

and result in an exception.

Memory Protection Unit (MPU)

A MPU restricts access to selected peripherals and memory regions so

they can only be accessed in a controllable way.

Secure Access Unit (SAU)

A SAU allows the user to set-up tunnels through regions pro-

tected by the MPU, allowing unrestricted access to speciﬁed

peripheral registers, reducing code size, and increasing ex-

ecution speed.

True 1.6V Operation

The 32-bit AVR UC3L family offers true 1.6V operation. All functions — including

ADC, DAC, onboard Flash and SRAM — are capable of operating down to 1.62V.

Minimized Leakage Current

The 32-bit AVR UC3L leakage current is only 100 nA retaining special purpose registers.

The leakage current with a real-time clock running is less than 1.5 µA. The real-time clock

includes a calendar mode, ensuring that clock cycles are not wasted on

calculating date and time.

Ultra Low Power 32 KHz Crystal Oscillator

The 32-bit AVR UC3L Real Time Clock consumes less than 1.5 µA while running from a 32.768 kHz crystal

oscillator.

Multiple Clock Domains

The main databus and two peripheral data buses can all be set to individual clock frequencies to ensure that

no unnecessary power is consumed. The UC3 microcontrollers also feature two crystal oscillators and dual

PLLs and DFFLs to simplify the task of selecting a suitable crystal

frequency for peripherals such as USB, UART and audio codec.

Dynamic Frequency Scaling

Dynamic Frequency Scaling (DFS) reduces power consumption

when maximum speed is not required throughout the execution of

an application. DFS makes it possible to adapt the clock frequency

on-the-ﬂy to an application without halting program execution.

Individual Peripheral Clock Control

It is used to turn the clocks on or off dynamically for peripheral units

not in use.

debugged.

page 13

The FlashVault code protection can carry software such as a math library or an encryption

algorithm to potentially untrustworthy environments where the rest of the source code can be developed

and debugged.

Other innovations ﬁrst introduced in the UC3L Series include SleepWalking™ intelligent peripherals, a

Peripheral Event System, Clock Failure Protection, Spread Spectrum Clocks with fast startup times, a

Frequency Meter, an RTC with Crystal Precision Tuner and calendar mode, and a PWM output on all 36

I/O pins.

The L series is targeted at portable consumer applications, board controller, game pads, remote con-

trols, and human interface devices.
