The next generation of AVR: Atmel 8-bit market, specializing in

32-bit MCU application of increasingly prosperous, stable 8-bit MCU, 16-bit MCU in the middle, the situation is more embarrassing. It is in many companies has become a trend that when the 32-bit MCU, this time, Atmel is contrarian, high-profile release of its 8-bit AVR XMEGA series, mainly aimed at 8-bit, 16-bit MCU applications.
"We are very concerned about the 8-bit MCU market." Atmel AVR Product Marketing Director Ingar Fredriksen, told reporters that the world of electronic engineering. Throughout the MCU market is not difficult to find: Although 32-bit MCU market is growing rapidly, but the 8-bit, 16-bit MCU still occupies the largest share of this market, and continues to grow. 32-bit MCU for high requirements on the design of computing power, while the 8-bit and 16-bit for some of the cost-sensitive designs. Among them, 16-bit MCU is a relatively awkward market, many 16-bit applications using the 8-bit MCU architecture, at the same time, there are many manufacturers of products with its 32-bit to attack the 8-bit, 16-bit MCU market.
"Maybe because other vendors do not have a very good 8-bit, 16-bit solutions and architecture, so they use relatively low-level products to attack 32-bit 8-bit and 16-bit MCU market, I think this is an awkward 16-bit market The main reason, "Fredriksen said.
XMEGA - based on the 8-bit MCU, the expansion to 16-bit MCU
XMEGA new series, is to see such a direction, 8-bit MCU-based architecture, the Atmel 8-bit market increased to 16-bit applications in the market. In particular, the future number of emerging applications, such as three or four years ago, touch screen, is a typical 8-bit or 16-bit MCU applications.
Of course, a product launch, not imagined out. Atmel in 2005, 2006 1100 AVR customers ask when they expect to improve that: first, they need more internal SRAM, a faster core speed, AD hope to have a higher resolution. They also have a lot of demand on the system performance in the analog conversion, they need a faster speed of AD conversion. Features listed in the survey, XMEGA can achieve full expression.

PicoPower technology by the second generation of AVR XMEGA product has many features, such as real 1.6V operating voltage, current consumption of only 1 uA combo watchdog timer and voltage detection device, further extending battery life in portable devices. 1.6V operating voltage means the real, including Flash reprogramming, EEPROM write, analog conversions and internal oscillator circuit, including all the features available on the 1.6V voltage. In battery-powered devices such as mobile phones, XMEGA devices can be connected to a 1.8V (+ / - 10%) of the power supply to save cost and extend battery life. To maintain RAM contents in Power Down mode, current consumption is 100 nA. Real-time clock by a 32 kHz crystal oscillator to achieve a consumption of only 650 nA.
CPU architecture - This 8-bit AVR CPU for advanced programming languages (such as the C language) designed to support 16-bit and 32-bit computing, and with 16-bit and 24-bit memory pointer. The AVR CPU with a single-cycle operation function, and 32 working registers connected to the arithmetic logic unit (Arithmetic Logic Unit), which is more efficient than other CPU.
Event system - as the body's ability to reflex-like, the event system can not use CPU or DMA resources to complete the communication between the peripherals, which can ensure 100% predictable and fast response. Up to 8 simultaneously in the peripheral events or interrupt conditions in the peripherals can automatically trigger responses in the other. The event system eliminates the interruption due to multiple and / or frequently triggering interrupts caused by the bottleneck effect, event handling without the use of any software, and the delay time to ensure that mission-critical than any interrupt response time must be short.
Analog Performance-XMEGA ADC with 12 bit resolution, sampling rates up to 200 million times per second, and has been sampling (oversampling) hardware support, so no additional cost, you can increase the resolution to 16 bits. The converter with programmable gain stage, differential inputs, temperature sensor, and accurate internal voltage reference, no external components and saves cost. AVR XMEGA also has advanced 12-bit DAC and analog comparators.
Encryption engine-XMEGA with a support Advanced Encryption Standard (AES) and Data Encryption Standard (DES) hardware encryption engine. The encryption engine data can be encrypted communication speed from 10 kbps up to 2 Mbps, more efficient than software solutions.
Development Tools - XMEGA AVR devices by the existing tool chain support.
For different functions, XMEGA also have different applications. For example, XMEGA picoPower added a second-generation technology, low-power features, mainly for fire alarms, temperature controller, and do not want long battery life applications often replace the battery. Water and other needs for high-precision analog - digital conversion applications, XMEGA can provide 12-bit AD conversion, while the previous AVR was 10. Particularly in the EMC aspects of XMEGA suitable for use in white goods. "One of the application of toll on the market have no way of many other competitors also meet this requirement." Fredriksen introduced. Operation by the battery charging system requires radio and encryption technology, XMEGA low power consumption and the use of hardware for the encryption engine, just to meet these requirements.
Of course, each product are popular from the launch to take some time. An example to AVR, AVR developed in 1996, to the rapid growth experienced three or four years time. AVR32 architecture has been around for two years of this, the product will really come out 1 year's time, so the AVR32 recognized by the market may need more time. The XMEGA is the same with the AVR architecture, XMEGA function is to do a survey of the existing AVR, so XMEGA market acceptance than the AVR32 more. XMEGA only in the performance of a system upgrade is the same development tools, code is the same.
For the Chinese market, Atmel will make some reference to the applications and the technical team and the target customers for training. And the addition of some Chinese version of the technical support documents to help the Chinese technology market will face questions and answers.
