Atmel SAM D20J / SAM D20G / SAM D20E

ARM-Based Embedded Flash Microcontroller

PRELIMINARY DATASHEET

Description

The Atmel^®SAM D20 family is a series of low-power, high-performance, ARM^®-based

embedded flash microcontrollers based on the ARM Cortex^®-M0+ 32-bit processor.

Operating at a maximum speed of 48MHz, and with a two-stage pipeline, single-cycle

I/O access, single-cycle 32x32 multiplier, Event System and a fast and flexible interrupt

controller, the SAM D20 series microcontrollers are highly efficient, reaching

2.14 Coremark/MHz – 0.93 DMIPS/MHz.

All devices in the SAM D20 series contain multiple instances of the Serial

Communication Interface (SERCOM). The SERCOM is a very flexible serial

communication interface, configurable to operate as I²C, SPI or USART, giving

developers extended flexibility not only in the mix of serial interfaces available, but also

in PCB layout. Additionally, each SERCOM instance can be assigned to different I/O

pins through I/O multiplexing, further increasing flexibility.

The 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. The TCs can be configured to operate in 8-bit and 16-bit modes, and

two TCs can be cascaded to form a 32-bit TC.

The SAM D20 series Power Manager (PM) has two software-selectable sleep modes,

idle and standby. The standby mode supports SleepWalking functionality, by which a

peripheral can be selectively activated based on events, even when the peripheral

clock is stopped. In addition the Event System (EVSYS) supports asynchronous

events, allowing peripherals to receive, react to and send events, even in standby

mode.

The devices feature several oscillators, such as a 48MHz Digital Frequency Locked

Loop (DFLL48M), 400kHz – 32MHz External Crystal Oscillator (XOSC), 8MHz Internal

Oscillator (OSC8M), 32kHz Ultra-Low-Power Internal Oscillator (OSCULP32K),

32.768kHz High-Accuracy Internal Oscillator (OSC32K) and 32.768kHz Crystal

Oscillator (XOSC32K). Any of these oscillators can be used as a source for the system

clock. Different clock domains can be independently configured to run at different

speeds, enabling the user to save power by running each peripheral at the optimal

clock frequency, and thus maintain a high CPU speed and throughput while reducing

system power consumption.
