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 I2C-bus interfaces (TWI), up to two SPIs, two three-channel general-purpose 16-bit timers, two I2S controllers with two-way, one-channel pulse density modulation, one realtime 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 events, including partial asynchronous wake-up (SleepWalking™). 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.
