The Atmel® SAM7L is a high-performance, ultra-low power ARM7TDMI®-based microcontroller, offering reduced power consumption in active and standby modes. With power consumption levels as low as 100nA, the SAM7L is unique in its category. To achieve this, Atmel implements power-saving techniques such as programmable operating voltage and operating frequency, the use of DMA instead of the CPU for data transfers, and embedded power switches and voltage regulators. The extensive peripheral set includes a 40-segment LCD controller, USART, SPI, Timer Counter, RTC and ADC, as well as a complete set of system functions.
