SMART ARM-Based Microcontroller
DATASHEET
Description
The Atmel® | SMARTSAM D21 is a series of low-power microcontrollers using the 32-bit
ARM® Cortex®-M0+ processor, and ranging from 32- to 64-pins with up to 256KB Flash and
32KB of SRAM. The SAM D21 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 Atmel SAM D21 devices provide the following features: In-system programmable Flash,
twelve-channel direct memory access (DMA) controller, 12 channel Event System,
programmable interrupt controller, up to 52 programmable I/O pins, 32-bit real-time clock and
calendar, up to five 16-bit Timer/Counters (TC) and three 24-bit Timer/Counters 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 8- or 16-bit mode, selected TCs can be cascaded to form
a 32-bit TC, and three timer/counters have extended functions optimized for motor, lighting and
other control applications. The series provide one full-speed USB 2.0 embedded host and device
interface; up to six 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; two-channel I2S
interface; up to twenty-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 256
buttons, sliders, wheels and proximity sensing; programmable Watchdog Timer, brown-out
detector and power-on reset and two-pin Serial Wire Debug (SWD) program and debug interface.
All 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 consumption.
The SAM D21 devices have two software-selectable sleep modes, idle and standby. 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, e.g. 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 mode.
The Flash program memory can be reprogrammed in-system through the SWD interface. The
same interface can be used for non-intrusive on-chip debug 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 memory.
The Atmel SAM D21 devices are supported with a full suite of program and system development
tools, including C compilers, macro assemblers, program debugger/simulators, programmers and
evaluation kits.
