Atmel SAM D20J / SAM D20G / SAM D20E
SMART ARM-Based Microcontroller
DATASHEET
Description
The Atmel® | SMARTSAM D20 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 D20 devices operate at a maximum frequency of 48MHz and
reach 2.14 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 | SMART SAM D20 devices provide the following features: In-system
programmable Flash, eight-channel Event System, programmable interrupt controller, up to
52 programmable I/O pins, 32-bit real-time clock and calendar, up to eight 16-bit
Timer/Counters (TC). The timer/counters can be configured to perform frequency and
waveform generation, program execution timing or input capture with time and frequency
measurement of digital signals. The TCs can operate in 8- or 16-bit mode, or be cascaded
to form a 32-bit TC. The series provide up to six Serial Communication Modules (SERCOM)
that each can be configured to act as an USART, UART, SPI and I2C up to 400kHz; 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 while enabling power saving by running each
peripheral at its optimal clock frequency.
The Atmel | SMART SAM D20 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 | SMART SAM D20 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.
