Atmel SAM D Family
ARM Cortex-M0+ based Flash Microcontrollers
SERCOM
SAM D devices feature multiple instances of the Serial
Communication Module (SERCOM). The SERCOM is
configurable to operate as I2C, SPI or USART, giving
developers extended flexibility to mix serial interfaces and
greater freedom in PCB layout. Each SERCOM instance can
be assigned to different I/O pins through I/O multiplexing,
further increasing versatility.
Micro Trace Buffer
The Micro Trace Buffer available in selected SAM D devices
enables enhanced on-chip debugging with trace capabilities
supported by Atmel and third-party debuggers.
FS USB 2.0
Selected SAM D products feature Full Speed USB device
and embedded host. In Device mode, a SAM D device can
operate from the internal RC oscillator giving you a minimum
Bill of materials and PCB-area implementation. The USB
drivers are available from Atmel through the Atmel Software
Framework.
I2S
The Inter-IC Sound Controller (I2S) provides a bidirectional,
synchronous digital audio link with external audio devices.
Peripheral DMA channels, separate for each Serializer, allow
a continous high bit rate data transfer without processor
intervention. The SAM D devices with I2S have a built in
frational PLL to support glitch free audio streaming from USB
to I2S.
DMA
Up to 12 DMA channels are available in SAM D. The DMA
supports data transfers from 1B to 256KB and has selectable
transfer triggers and priority levels. The DMA is connected to
the ADC, DAC, I2S, SERCOM, T/C and the T/CC.
Peripheral Touch Controller
An embedded peripheral touch controller (PTC) makes it
easy to add capacitive touch sensing to your project with
buttons, sliders, wheels and proximity. The PTC supports
Mutual and self capacitive touch and offers superb sensitivity
and noise tolerance as well as self-calibration, the PTC
eliminates the need for external components and minimizes
CPU overhead. Implementing one button takes one channel,
while wheels and sliders take 3 channels to implement.
Timers/Counters
SAM D devices include multiple instances of 16-bit Timer/
Counters (TC). Each TC can be individually programmed
to perform frequency and waveform generation, accurate
program execution timing, and input capture with time and
frequency measurement of digital signals. Each TC can be
configured to operate as 2x8-bit timers, as a 16-bit timer,
and two TCs can be combined to a 32-bit TC. In addition,
the SAM D family features a 32-bit RTC with full calendar
and leap year support.
Timers/Counters for Control
Selected SAM D have T/CCs, these are Timers/Counters
for control applications like switch mode power supplies,
lighting and motor control. The T/CCs support up to 96MHz
and 24 bit resolution.
