Product Overview
ATSAMD20J16B-MNT is a SAM D20 series low-power microcontroller using the 32-bit ARM® Cortex® -M0+ processor. The SAM D20 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 signalling, and support for capacitive touch button, slider and wheel user interfaces.
- 64KB in-system self-programmable flash memory, 8KB SRAM memory
- Operating temperature range from -40⁰C to 105⁰C
- 8 x timer counter instances, 2 x waveform output channels per TC instance
- 6 x serial communication Interface (SERCOM) instance
- 20 x ADC channels, 1 x DAC channels, 1 x RTC alarms, 16 x external interrupt lines
- Power-on reset (POR) and brown-out detection (BOD)
- External interrupt controller (EIC), 16 external interrupts, one non-maskable interrupt
- Two-pin serial wire debug (SWD) programming, test and debugging interface
- 32-bit real time counter with clock/calendar function, watchdog timer, 8-channel event system
