General description
The SAM D21/DA1 is a series of low-power microcontrollers using the 32-bit Arm® Cortex®-M0+ processor, andranging from 32-pins to 64-pins with up to 256 KB Flash and 32 KB of SRAM. The SAM D21/DA1 operates at amaximum frequency of 48 MHz and reach 2.46 CoreMark/MHz. They are designed for simple and intuitive migrationwith identical peripheral modules, hex compatible code, identical linear address map, and pin compatible migrationpaths between all devices in the product series. All devices include intelligent and flexible peripherals, Event Systemfor inter-peripheral signaling, and support for capacitive touch button, slider, and wheel user interfaces.The SAM D21/DA1 provides the following features: In-system programmable Flash, 12-channel Direct MemoryAccess Controller (DMAC), 12-channel Event System, programmable Interrupt Controller, up to 52 programmableI/O pins, 32-bit Real-Time Clock and Calendar (RTC), up to five 16-bit Timer/Counters (TC) and up to four 24-bitTimer/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 TCscan operate in 8-bit or 16-bit mode, selected TCs can be cascaded to form a 32-bit TC, and three timer/countershave extended functions optimized for motor, lighting, and other control applications. The series provide one fullspeed USB 2.0 embedded host and device interface; up to six Serial Communication Modules (SERCOM) that eachcan be configured to act as an USART, UART, SPI, I2C up to 3.4 MHz, SMBus, PMBus, and LIN client; two-channelI2S interface; up to twenty-channel 350 ksps 12-bit ADC with programmable gain and optional oversampling anddecimation supporting up to 16-bit resolution, one 10-bit 350 ksps DAC, up to four analog comparators with Windowmode, Peripheral Touch Controller (PTG) supporting up to 256 buttons, sliders, wheels, and proximity sensing;programmable Watchdog Timer (WDT), brown-out detector and power-on Reset and two-pin Serial Wire Debug(SWD) program and debug interface.
