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.

Power Considerations 5.1 Power Supplies The SAM G53 has several types of power supply pins:  VDDCORE pins: Power the core, including the processor, the embedded memories and the peripherals. VDDCORE must be connected to VDDOUT.  VDDIO pins: Power the peripheral I/O lines, voltage regulator and ADC; voltage ranges from 1.62V to 3.6V. The ground pins GND are common to VDDCORE and VDDIO. 5.2 Voltage Regulator The SAM G53 embeds a core voltage regulator that is managed by the Supply Controller and that supplies the Cortex-M4 core, internal memories (SRAM and Flash logic) and the peripherals. An internal adaptative biasing adjusts the regulator quiescent current depending on the required load current. For adequate input and output power supply decoupling/bypassing, refer to Table 37-4 “VDDCORE Voltage Regulator Characteristics” in the Electrical Characteristics section of the datasheet. 5.3 Typical Powering Schematics The SAM G53 supports a 1.62V to 3.6V single supply mode. The internal regulator input is connected to the source and its output feeds VDDCORE. Power schematics are illustrated in Figure 5-1. To achieve the system performance levels, the internal regulator must be used. Figure 5-1. Single Supply VDDIO Main Supply (1.62V to 3.6V) VDDIO Voltage Regulator VDDOUT VDDCORE 5.4 Functional Modes 5.4.1 Active Mode Active mode is the normal running mode with the core clock running from the fast RC oscillator, the main crystal oscillator or the PLL. The Power Management Controller can be used to adapt the frequency and to disable the peripheral clocks. 10 SAM G53G / SAM G53N [DATASHEET] Atmel-11240F-ATARM-SAM-G53G-SAM-G53N-Datasheet_24-Jul-15 5.4.2 Wait Mode Wait mode allows the device to achieve very low power consumption levels while remaining in a powered state with a wake-up time of less than 5 µs. Current consumption in Wait mode is typically less than 8 µA (total current consumption). In Wait mode, the clocks of the core, the peripherals and memories are stopped. However, power supplies are maintained to ensure memory and CPU context retention. The wake-up time of 5 µs is achieved when entry into and exit from Wait mode are performed in internal SRAM. The wake-up time increases to 70 µs if entry into Wake-up mode is performed in internal Flash. Wait mode is entered using either the WAITMODE bit in the PMC Clock Generator Main Oscillator register (CKGR_MOR) or the Wait for Event (WFE) instruction. Detailed sequences are provided below. Note that the WFE instruction can add complexity in application state machines due to the fact that the WFE instruction goes along with an event flag of the Cortex core (cannot be managed by the software application). The event flag can be set by interrupts, a debug event or an event signal from another processor. Since an interrupt can take place just before the execution of WFE, WFE takes into account events that happened in the past. As a result, WFE prevents the device from entering Wait mode if an interrupt event has occurred. To work around this complexity, follow the sequence using the WAITMODE bit described below. The Cortex-M4 processor is able to handle external or internal events in order to wake up the core. This is done by configuring the external lines WKUP0–15 as fast start-up wake-up pins (refer to Section 5.5 “Fast Start-up”) or the RTT and RTC alarms for internal events. To enter Wait mode using the WAITMODE bit: 1. Select the 8/16/24 MHz fast RC oscillator as the Main Clock. If frequency of 24 MHz is selected and the code is running from the SRAM, wake-up time is less than 5 µs. 2. Program the FLPM field in the PMC Fast Startup Mode Register (PMC_FSMR)(1). 3. Set the number of Flash wait states to 0 by writing a zero to the FWS field in the EEFC Flash Mode Register (EEFC_MR). 4. Write a one to the WAITMODE bit in the PMC Clock Generator Main Oscillator Register (CKGR_MOR). 5. Wait for MCKRDY = 1 in the PMC Status Register (PMC_SR). To enter Wait mode using the WFE instruction: 1. Select the 8/16/24 MHz fast RC oscillator as the Main Clock. If 24 MHz is selected and the code is running on the SRAM, wake-up time is less than 5 µs. 2. Program the FLPM field in the PMC Fast Startup Mode Register (PMC_FSMR)(1). 3. Set the number of Flash wait states to 0 by writing a zero to the FWS field in the EEFC Flash Mode Register (EEFC_MR). 4. Write a one to the LPM bit in the PMC Fast Startup Mode Register (PMC_FSMR). 5. Ensure that the SLEEPDEEP bit in the System Control Register (SCB_SCR) is cleared. 6. Execute the Wait For Event (WFE) instruction of the processor. Note: 5.4.3 1. Depending on the value of the field FLPM, the Flash enters three different modes:  FLPM = 0: Flash in Stand-by mode (low power consumption levels)  FLPM = 1: Flash in Deep power-down mode (extra low power consumption levels)  FLPM = 2: Flash in Idle mode. Memory ready for Read access. Sleep Mode In Sleep mode, power consumption of the device versus response time is optimized. Only the core clock is stopped. The peripheral clocks can be enabled. The current consumption in Sleep mode is application-dependent. Sleep mode is entered via Wait for Interrupt (WFI) instructions. The processor can be awakened from an interrupt if the WFI instruction of the Cortex-M4 is used.
