SAM G53G / SAM G53N
Atmel | SMART ARM-based Flash MCU
DATASHEET
Description
The Atmel
®
| SMART SAM G53 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 48 MHz and features up to 512 Kbytes of Flash and 96 Kbytes
of SRAM. The peripheral set includes one USART, two UARTs, three I
2
C-bus
interfaces (TWI), up to two SPIs, two three-channel general-purpose 16-bit timers,
two I
2
S controllers with two-way, one-channel pulse density modulation, one real-
time timer (RTT) and one 8-channel 12-bit ADC.
The Atmel | SMART SAM G53 devices have two software-selectable low-power
modes: Sleep and Wait. 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.
The Event System allows peripherals to receive, react to and send events in
Active and Sleep modes without processor intervention.
A general-purpose microcontroller with the best ratio in terms of reduced power
consumption, processing power and peripheral set, the SAM G53 series sustains
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 a 49-ball WLCSP
package and a 100-pin LQFP package.
