Flash MCU ups impedance matching at low power

The SAM3S integrates up to 16 channels on the 1MSps 12bit ADC with support for both single-ended and differential inputs. A programmable gain amplifier increases the range of small signals that can benefit from the full-scale 12bit ADC resolution. Small signals can be amplified up to 4 times. The SAM3S also features a two-channel 12bit DAC, one analog comparator and a temperature sensor. Connectivity to standard multimedia cards is possible due to the integration of a high-speed SDIO/SD/MMC interface. The USB device with its integrated transceiver have been upgraded with eight endpoints, 2688 bytes FIFO, a dedicated PLL, integrated resistors, and is available in 48-pin package for space constraint applications. The SAM3S is hardware-ready for motor control with its advanced PWM, quadrature decoder on 16bit general-purpose timers, gray counter and hardware synchronization between Timers and ADC.

Atmel's SAM3S flash MCU is supported by a rapidly growing number of development tools, RTOS, middleware products and technical support services from industry-leading third parties that include IAR, Keil, Micrium and Segger. The automatic reboot from the on-chip ROM after flash memory erase facilitates In-System production programming. Atmel provides a software package with register descriptions and device drivers for all peripherals, along with project examples that create an easier use of the MCU.

The SAM3S is available in flash memory densities of 64-, 128- and 256Kbytes and ships in 48-, 64- and 100-pin QFP, 48- and 64-pin QFN packages, and in 100-pin 0.8mm pitch BGA packages. Sampling starts with the 256KByte Flash memory density parts in 64- and 100-pin QFP packages and the others will follow in Q1 10. Production volumes will be available in Q2 10, with prices ranging from $2.50 to $4.45 in quantities of 10,000 units.
