32-bit MCUs
SAM4N Microcontroller Family
Summary
Entry Point to Microchip's ARM
®
Cortex
®
-M4-Based Flash MCU Portfolio
Microchip's SAM4N series comprises the entry point to our portfolio of
ARM
®
Cortex
®
-M4-based Flash microcontrollers (MCUs). These MCUs fea-
ture a 100 MHz operating frequency and offer up to 1 MB of Flash, multiple
serial communication peripherals and analog capability. This combination of
features—plus low power consumption—makes the SAM4N series ideal for
a wide range of applications in industrial automation, consumer and appli-
ance and energy metering markets.
The SAM4N series offers pin-to-pin compatibility with SAM4S, SAM3S,
SAM3N and SAM7S devices, facilitating easy migration within the portfolio.
Key Features
•
High level of integration
— SAM4N devices offer fast serial communication with seven UARTs, four SPIs and three I
2
Cs.
Additional features include 12-bit ADC, 10-bit DAC, integrated voltage reference, multiple timers, PWM and more.
•
Low power consumption
— With its low-power architecture, the SAM4N MCU achieves power consumption levels down to
170 µA/MHz in Active mode; as low as 20 µA in Sleep mode with full RAM retention and wake-up time down to 10 µs; requir-
ing as little as 1 µA in backup mode with the RTC running.
•
Ease of use
— The ecosystem of software tools and support for the Atmel Studio Integrated Development Environment (IDE)
enables an efficient design process and reduces time to market.

Design Tools and Ecosystem
Microchip offers a full suite of hardware tools for evaluation and prototyping with the SAM4N series. All SAM4N evaluation tools
are supported by the Atmel Studio IDE and integrated Microchip QTouch
®
library support for buttons, sliders and wheels.
They are backed by a worldwide support ecosystem of industry-leading suppliers of development tools, real-time operating
systems and middleware products to make your design process easier and reduce time-to-market.
SAM4N Xplained Pro
The SAM4N Xplained Pro platform consists of a main board with multiple expan-
sion ports plus extension boards, including OLED LCD displays, buttons, sensors
and more. The board is available as a standalone kit. The extension boards can
also be purchased separately.
