SAM G55G / SAM G55J
Atmel | SMART ARM-based Flash MCU
SUMMARY DATASHEET
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 I2c-bus Interfaces (twis), Two
Three-channel General-purpose 16-bit Timers, Two I2s 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.
