| Atmel’s AT91SAM7SE 32-bit Flash MCU Named in EDN’s Hot 100 Products of 2006 | | | | Rousset, France, Atmel® Corporation, a global leader in the development and fabrication of advanced semiconductor solutions, announced today that its AT91SAM7SE ARM®-based 32-bit Flash microcontroller has been included in EDN’s annual list of Hot 100 Products in the Processors category.
These products are featured in EDN’s December 15, 2006 issue and can be viewed at http://www.edn.com.
The AT91SAM7SE-series is the industry’s first family of ARM7 Flash MCUs to Support 1G byte-Plus SDRAM, NAND Flash and CompactFlash®, and they feature a universal memory interface including an Error Correcting Code Controller (ECC). Available with on-chip Flash memory densities of 32K, 256K, and 512K bytes, the AT91SAM7SE microcontrollers also include the same supervisory features found on 8-bit MCUs including a brown-out detector, power-on-reset, real-time clock, crystal oscillator, watchdog timer and three 16-bit timers. Communication interfaces include three USARTs, USB, TWI, I2S (SSC) and SPI. The device also has four pulse width modulators (PWM), an 8-channel, 10-bit analog-to-digital converter (ADC) and 88 I/O pins.
Like Atmel’s other AT91SAM7 MCUs, the AT91SAM7SE-series has an 11-channel peripheral DMA controller (PDC) that increases on-chip bandwidth to 10 Mbps while maintaining 96% of the CPU’s cycles for application processing. The PDC can store the streaming content directly in the external NAND Flash or SDRAM without CPU intervention making these MCUs ideal for data logging applications such as ambulatory medical monitoring.
Products that appear in EDN’s annual Hot 100 Products issue are chosen by its editors from the hundreds of newsworthy items that grace the pages of EDN, whether they appeared in EDN’s New Products section, a feature story, or an online exclusive. The list encompasses a range of architectures and technologies and numerous categories—from analog ICs to multimedia to test-and-measurement tools.

No podía ser uno un buen científico sin comprender que un buen número de ellos no sólo son obtusos y de mentalidad estrecha, sino también simplemente estúpidos.
