Atmel SAM D09 - Microchip Technology

1 Atmel -42414G-SAM-D09-Datasheet_09/2016 SMARTD escriptionThe Atmel | SMART sam d09 is a series of low-power microcontrollers using the 32-bit ARM Cortex -M0+ processor, and ranging from 14- to 24-pins with up to16KB Flash and 4KB of SRAM. The sam d09 devices operate at a maximum frequency of 48 MHz and reach Coremark/MHz. They are designed for simple and intuitive migration with identical peripheral modules, hex compatible code, identical linear address map and pin compatible migration paths between all devices in the product series. All devices include intelligent and flexible peripherals, Atmel Event System for inter-peripheral signaling, and support for capacitive touch button, slider and wheel user interfaces. The sam d09 series is compatible to the other product series in the SAM D family, enabling easy migration to larger device with added Atmel sam d09 devices provide the following features: In-system programmable Flash, six-channel direct memory access (DMA) controller, 6 channel Event System, programmable interrupt controller, up to 22 programmable I/O pins, 32-bit real-time clock and calendar, two 16-bit Timer/Counters (TC), where each TC can be configured to perform frequency and waveform generation, accurate program execution timing or input capture with time and frequency measurement of digital signals.

2 The TCs can operate in 8- or 16-bit mode, selected TCs can be cascaded to form a 32-bit TC, and one timer/counter has extended functions optimized for motor, lighting and other control applications. The series provide two Serial Communication Modules (SERCOM) that each can be configured to act as an USART, UART, SPI, I2C, SMBus, PMBus and LIN slave; up to 10-channel 350ksps 12-bit ADC with programmable gain and optional oversampling and decimation supporting up to 16-bit resolution, programmable Watchdog Timer, brown-out detector and power-on reset and two-pin Serial Wire Debug (SWD) program and debug devices have accurate and low-power external and internal oscillators. All oscillators can be used as a source for the system clock. Different clock domains can be independently configured to run at different frequencies, enabling power saving by running each peripheral at its optimal clock frequency, and thus maintaining a high CPU frequency while reducing power sam d09 devices have two software-selectable sleep modes, idle and standby.

3 In idle mode the CPU is stopped while all other functions can be kept running. In standby all clocks and functions are stopped expect those selected to continue running. The device supports SleepWalking. This feature allows the peripheral to wake up from sleep based on predefined conditions, and thus allows the CPU to wake up only when needed, when a threshold is crossed or a result is ready. The Event System supports synchronous and asynchronous events, allowing peripherals to receive, react to and send events even in standby Flash program memory can be reprogrammed in-system through the SWD interface. The same interface can be used for non-intrusive on-chip debug and trace of application code. A boot loader running in the device can use any communication interface to download and upgrade the application program in the Flash Atmel sam d09 devices are supported with a full suite of program and system development tools, including C compilers, macro assemblers, program debugger/simulators, programmers and evaluation sam d09 SMART ARM-Based MicrocontrollerDATASHEET2 Atmel | SMART sam d09 [DATASHEET] Atmel -42414G-SAM-D09-Datashee t_09/2016 FeatureszProcessorzARM Cortex-M0+ CPU running at up to 48 MHzzSingle-cycle hardware multiplierzMicro Trace BufferzMemoriesz8/16KB in-system self-programmable Flashz4KB SRAM MemoryzSystemzPower-on reset (POR) and brown-out detection (BOD)zInternal and external clock options with 48 MHz Digital Frequency Locked Loop (DFLL48M) and 48 MHz to 96 MHz Fractional Digital Phase Locked Loop (FDPLL96M)

To enable a peripheral function on a pin, the Peripheral Multiplexer Enable bit in the Pin Configuration register corresponding to that pin ( , n = 0-31) in the PORT must be written to one. The selection of peripheral function A to H is done by writing to the Peripheral Multiplexing Odd and Even bits in the Peripheral Multiplexing register ( ) in the PORT.

10 Table 5-1 on page 11 describes the peripheral signals multiplexed to the PORT I/O to Electrical Characteristics on page 648 for details on the I2C pin some pins can be used in SERCOM I2C mode. See the Type column for using a SERCOM pin in I2C function is only activated in the presence of a the PA24 and PA25 pins are not connected, it is recommended to enable a pull-up on PA24 and PA25 through input GPIO mode. The aim is to avoid an eventually extract power consumption (<1mA) due to a not stable level on 6-1.
