Improved ARM Cortex M4 MCU from Atmel with 1MB flash

Atmel Corporation has expanded its ARM Cortex-M4 based flash family with new MCU featuring latest connectivity peripherals, a floating point unit (FPU), improved analog capabilities, and enhanced processing abilities. The new MCUs targets applications such as industrial automation, home and building control, machine-to-machine communications, automotive aftermarket and energy management applications.

Atmel SAM4E ARM Cortex-M4 processor-based MCUs offer more processing power with a maximum operating frequency of 120MHz, a FPU and an integrated cache providing zero wait state flash access at full speed. The SAM4E includes embedded flash memory up to 1MB, safety and security features, and extensive communication links such as Ethernet IEEE1588 MAC, USB 2.0 device and dual CAN. The high performance and high-system integration of the SAM4E addresses the growing application requirements for high-speed wired and wireless communications.

The advanced analog technology on the device includes two independent 16-bit ADCs offering dual sample and hold capability, offset and gain error correction, programmable-gain amplifier enabling measurement of a wide input signal range with high precision.

"Industrial applications that serve the manufacturing automation market, such as programmable logic controller (PLC), require microcontrollers that deliver higher performance, advanced connectivity and better analog capability," said Ingar Fredriksen, Sr. Director of Microcontroller Products, Atmel Corporation. "The new Atmel SAM4E series addresses these specific requirements with a unique combination of just that - more connectivity, higher performance with a floating point unit and advanced analog. The new ARM Cortex-M4 series rounds out our diverse ARM product portfolio to offer designers a full breadth of devices based on the popular ARM core."

Package: Two memory options 512KB and 1MB in BGA and QFP packages.
Price: Starts at $5.10 USD for 1,000-piece quantities.

Availability: Now in samples with general availability in February 2013. The ATSAM4E-EK evaluation kit is available now.
