Atmel SAM D09
SMART ARM-Based Microcontroller
DATASHEET
Description
The AtmelВ® | SMARTв„ў SAM D09 is a series of low-power microcontrollers using the 32-bit
ARMВ® CortexВ®-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 48MHz and reach
2.46 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 features.
The Atmel SAM D09 devices provide the following features: In-system programmable Flash, sixchannel 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 16bit 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. 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 …
