SAMD21J - SMART ARM-Based Microcontroller

This page provides the datasheet information for the SAMD21J, a member of the SAMD21E SMART ARM-Based Microcontroller family.

Datasheet Summary

Description

The Atmel® | SMART™ SAM D21 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 D21 devices operate at a maximum frequency of 48MHz and reach 2.46 CoreMark/MHz.

Features

  • In-system programmable Flash, twelve-channel direct memory access (DMA) controller, 12 channel Event System, programmable interrupt controller, up to 52 programmable I/O pins, 32-bit real-time clock and calendar, up to five 16-bit Timer/Counters (TC) and three 24-bit Timer/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 TCs can.

SMART Atmel SAM D21E / SAM D21G / SAM D21J SMART ARM-Based Microcontroller DATASHEET Description The Atmel® | SMART™ SAM D21 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 D21 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 signaling, and support for capacitive touch button, slider and wheel user interfaces.
