Atmel SAM D11
SMART ARM-Based Microcontroller
DATASHEET
Description
The AtmelВ® | SMARTв„ў SAM D11 is a series of low-power microcontrollers using the 32-bit
ARMВ® CortexВ®-M0+ processor, and ranging from 14-to 24-pins with 16KB Flash and 4KB of
SRAM. The SAM D11 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 D11 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 D11 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) and one 24-bit Timer/Counter for Control (TCC), 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 8or 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
one full-speed crystal-less USB 2.0 device interface; up to three Serial Communication Modules
(SERCOM) that each can be configured to act as an USART, UART, SPI, I2C up to 3.4MHz,
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, one 10-bit 350ksps
DAC, two analog comparators with window mode, Peripheral Touch Controller supporting up to …
