Description
The Atmel
®
| SMART SAM G55 is a series of Flash microcontrollers based on the
high-performance 32-bit ARM
®
Cortex
®
-M4 RISC processor with FPU (Floating
Point Unit). 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 I
2
C-bus interfaces (TWIs),
two three-channel general-purpose 16-bit timers, two I
2
S controllers, one-channel
pulse density modulation, 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
events, including partial asynchronous wakeup (SleepWalking™). In Backup
mode, RTT, RTC and wakeup logic are running.
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 real-time event management allows peripherals to receive, react to and send
events in Active and Sleep modes without processor intervention.
The SAM G55 devices are general-purpose low-power microcontrollers that offer
high performance, processing power and small package options combined with a
rich 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.
