Atmel Announces Four New LCD AVR Microcontrollers

Atmel® Corporation announced four new members of the LCD AVR®Flash Microcontroller family. The mega329, 649, 3290 and 6490 are designed to address the requirements of portable and battery-operated applications like home appliance controllers, Audio/Video equipment and health care products. The mega329 and 649 have an integrated 100-segment LCD controller and are housed in a 64-pin package while the mega3290 and 6490 have a 160-segment LCD controller and are available in a 100-pin package.

The LCD AVR family of Flash microcontrollers consumes only 300µA at an operating frequency of 1 MHz and has an unrivaled throughput of 2 MIPS per milliwatt. In the Power-down mode, all peripherals, with the exception of external interrupts, are turned off and power consumption drops to 100nA. These parts are extremely responsive to external events in both active and power down modes. Interrupts on up to 18 inputs can wake the part from a power down mode in less than one microsecond, which is a 6x improvement.

To further reduce power consumption, the CPU clock is controlled by software. The designer can select a high clock frequency for computation-intensive operations, and slow the clock to 32 kHz or less to perform simple control functions. This means products designed with the LCD AVR family will be able to run up to 10 times longer on the equivalent battery power when compared to traditional microcontroller solutions.

The mega329 and 3290 are available today. The 10,000-unit prices are US$4.50 and US$4.95 respectively. The mega649 and 6490 will be available in Q1 2005 and priced at US$5.25 and US$5.75 with volume production expected in the second half of that year.

Atmel Launches New Digital Audio Broadcasting Baseband IC

Atmel's new ATR2740 digital audio broadcast (DAB) baseband IC is based on a stndard ARM core and requires only two external parts (a simple crystal and an 8MB Flash memory) to run the full DAB function. All RAM functions, such as interleaving or program memory, are incorporated into the device, same as the analog-to-digital converter. The ATR2740 works perfectly together with Atmel's DAB front-end devices U2730B and U2731B. The ATR2740 also provides a wide variety of supported interfaces: UART; USB; and SPI are available for control functions, SSO, SFCO and RDI interfaces as well as two audio outputs (I2S or SPDIF) implemented as data interfaces.

At a full decoding data bit rate of 1.8 Mbit/s, the device's power consumption is as low as 180 mW, which is the industry's lowest such value. The ATR2740's outstanding processing power enables the device to decode the full DAB data rate of 1.8 Mbit/s, which is needed especially for video and data streaming. In addition, the device provides sufficient unused processing power available on the ARM controller for customer software such as user interfaces. A complete MP3 player can be run without the need to add extra hardware to the device.

A complete set of hardware and software tools, including comprehensive documentation, is available on request. The software to run a DAB radio is available free of charge. This software covers all DAB-related functions and features as specified in Eureka 147.

Samples of the new ATR2740 baseband processor device in LQFP and BGA packages are available now. Pricing starts at US$16.00 in quantities of 10,000.
