AT91SAM7L 系列
芯片型号 描述
AT91SAM7L128

The 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.
