The Atmel®| SMART SAM G55 is a series of Flash microcontrollers based on the high-performance 32-bit ARM®Cortex®-M4 RISC processor. It operates at a maximum speed of 120 MHz and features 512 Kbytes of Flash and up to 176 Kbytes of SRAM. The peripheral set includes eight flexible communication units comprising USARTs, SPIs and I2C-bus interfaces (TWIs), two three-channel general-purpose 16-bit timers, two I2S controllers, one-channel pulse densitymodulation, one 8-channel 12-bit ADC, one real-time timer (RTT) and one real-time clock (RTC), both located in the ultra low-power backup area. The Atmel | SMART SAM G55 devices have three software-selectable low-power modes: Sleep, Wait and Backup. In Sleep mode, the processor is stopped while all other functions can be kept running. In Wait mode, all clocks and functions are stopped but some peripherals can be configured to wake up the system based on predefined conditions. This feature, called SleepWalking™, performs a partial asynchronous wake-up, thus allowing the processor to wake up only when needed. For power consumption optimization, the flexible clock system offers the capability of having different clock frequencies for some peripherals. Moreover, the processor and bus clock frequency can be modified without affecting the peripheral processing. The SAM G55 devices are general-purpose low-power microcontrollers that offer high performance, processing power and small package options combined with arich and flexible peripheral set. With this unique combination of features, the SAM G55 series is suitable for a wide range of applications including consumer,industrial control and PC peripherals. The device operates from 1.62V to 3.6V and is available in three packages:49-pin WLCSP, 64-pin QFN and 64-pin LQFP. |
