AT91SAM7A3The AT91SAM7A3 is a Flash microcontroller based on the 32-bit ARM7TDMI RISC processor optimized for embedded control. It features 256K bytes of embedded high-speed Flash and 32K bytes of SRAM.

Its extensive peripheral set includes two CAN 2.0B Controllers, 8-channel 20-bit PWM Controller, nine 16-bit general purpose Timers, 16-channel 10-bit ADCs, a USB 2.0 Full Speed Device Port, MCI, USARTs, SPI, SSC and TWI. Its Peripheral DMA Controller channels eliminate processor bottlenecks during peripheral-to-memory transfers. Its System Controller manages interrupts, clocks, power, time, debug and reset, significantly reducing the external chip count and minimizing power consumption.

In industrial temperature, worse case conditions the maximum clock frequency is 60MHz. Typical core supply is 1.8V, I/Os are supplied at 1.8V or 3.3V and are 5V tolerant. An integrated Voltage Regulator permits single supply at 3.3V. The AT91SAM7A3 is supplied in a 100-lead LQFP Green package.

AT91SAM7L128The AT91SAM7L128 is a member of a series of high-performance, ultra-low power ARM7TDMI®-based microcontrollers, embedding power switches controlling multiple power islands and programmable voltage regulators to reduce power consumption in active and standby modes. In active mode, the power consumption is optimized via a programmable operating voltage, operating frequency, and peripheral clock activity, and the use of DMA instead of the CPU for data transfers. The SAM7L128 operates in single supply mode down to 1.8V and consumes 0.5mA/MHz typical in active mode when executing code out of its Flash memory.

The power consumption in the different standby modes is controlled via power switches, scalable voltage regulators, and the use of sampling techniques on Voltage Monitors, Power On Reset and Brown Out Detector instead of continuous measurement. This provides a higher level of granularity than is available in competing products, while achieving at least the same levels of power saving. In power down mode, the AT91SAM7L consumes only a typical 100nA, which is believed to be a unique feature for 32-bit MCUs.
