SAM4N8/16 Description
The Atmel SAM4N series is a member of a family of Flash microcontrollers based on
the high performance 32-bit ARM® Cortex®-M4 RISC processor. It operates at a
maximum speed of 100 MHz and features up to 1024 Kbytes of Flash and up to 80
Kbytes of SRAM. The peripheral set includes 3x USARTs, 4x UARTs, 3x TWIs, 1x SPI,
as well as 1 PWM timer, 2x three-channel general-purpose 16-bit timers (with stepper
motor and quadrature decoder logic support), an RTC, a 10-bit ADC (up to 12-bit with
digital averaging) and a 10-bit DAC with an internal voltage reference.
The SAM4N device is a medium range general purpose microcontroller with the best
ratio in terms of reduced power consumption, processing power and peripheral set.
This enables the SAM4N to sustain a wide range of applications including industrial
automation and M2M (machine-to-machine), energy metering, consumer and
appliance, building and home control.
It operates from 1.62V to 3.6V and is available in 48-, 64- and 100-pin QFP, 48-, 64-pin
QFN, and 100-ball BGA packages.
The SAM4N series offers pin-to-pin compatibility with Atmel SAM4S, SAM3S, SAM3N
and SAM7S devices, facilitating easy migration within the portfolio.
The SAM4N series is the ideal migration path from the SAM4S for applications that
require a reduced BOM cost.
