Atmel Introduces AVR MCUs with (MCU) series of 32-bit floating point unit

Micro-controller and touch solutions leader Atmel (Atmel? Company) electronic music in 2010 in Munich, Germany announced that with a floating point unit (floating point unit, FPU) 32-bit AVR launched the first program? Micro-controller device (MCU) series. The latest AVR UC3 ? MCU series for industrial control applications with high processing power, the real 5V operation, high-speed communications and advanced security and unique combination of reliability, and the use of small and micro-encapsulation series.

IEEE 754-1985 compliant floating point unit can improve the Atmel's AVR UC3 CPU computing performance, accuracy and dynamic range. The inherent floating-point operations allows designers to use the full functionality of the tool kit to design the sensor and controller applications. In addition, advanced mathematical calculations help to improve the robot to the broader use of the audio signal processing and control of the car, filtering and noise suppression performance.
Atmel's AVR UC3 Haakon Skar, product marketing director, said: "The first phase of the other micro-controller product line AVR UC3 C-Series smaller space, and to provide more processing power MCU series offers a new higher performance, so that we can integrate new. floating-point unit, without increasing power consumption of the micro-controller. The new 32-bit AVR microcontrollers for industrial control AVR microcontroller family in the 8-bit lineup powerful application, aims to further expansion. "

UC3 C series is Atmel's first high-speed development of communications and 32-bit AVR microcontroller series, the range of 3.0 to 5.5V operating voltage design, 5V to real work. 5V supply voltage is one of many industrial control applications, in order to get a better signal to noise ratio and requirements, especially those who need a lot of switching current or very sensitive analog applications. UC3 C series and a 9-layer data bus, 64 4KB high-speed SRAM, and mixed high-speed communication peripherals, including a 100Mbps Ethernet, dual CAN interfaces and a full-speed USB interface settings. Large equipment also includes a SDRAM interface. System designers and hierarchical data bus and separate use of SRAM-based, high-speed communications can easily eliminate the conflict, in order to avoid packet loss or system performance.


UC3 C Series also integrates Atmel UC3 L series, is the 8-bit AVR? XMEGA? Products for use in the event the system peripherals. The event system, without CPU intervention allows for peripheral and peripheral operation to ensure the completion of two cycles and the delay between the start and operation of other peripheral devices to communicate, and ultimately eliminate the jitter and the traditional interrupt CPU may lead to unpredictable delays LCD module distributors China.

In addition, UC3 C series also includes FlashVault code protection feature, which allows on-chip flash memory security technology of some kind of Flash programming and lock in the chip to create the privacy protection of intellectual property rights of software code and a secure storage space. Normally stored in the FlashVault can code, but can not read, copy, or debugging. FlashVault the code protection features of the device can be used to load the math library and other important software or encryption algorithm, when from the software to a safe location may not be a trusted partner, which can be used to avoid software development, debugging and programming with other source code LCD module graphic.
New series offers UC3C to 22x22mm from the 9 x 9mm QFN64 package TQFP144 choices. With existing AVR microcontrollers Atmel UC3 A and B series products the same power of these devices.
