ARM Cortex-M4 flash controller family adds dual CAN connectivity and floating point unit

January 15, 2013 // By Nick Flaherty
Atmel has expanded its ARM Cortex-M4 based flash family with the SAM4E series that features advanced connectivity peripherals such as CAN, a floating point unit (FPU), advanced analog capabilities and higher processing power.

This rich mix of features make the SAM4E devices ideal for the industrial automation, home and building control, machine-to-machine communications, automotive aftermarket and energy management applications.
The SAM4E family offers 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, senior director of microcontroller products at Atmel. “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.”
To help accelerate a designer’s project, the SAM4E series, is supported by the Atmel Studio 6 integrated development platform (IDP). Available as a free download, Atmel Studio 6 includes the Atmel Software Framework, a complete library of source code, project examples, drivers and stacks. The IDP also features the Atmel Gallery app store for embedded tools and extensions and the Atmel Spaces collaborative workspace for software and hardware projects based on Atmel microcontrollers.
The SAM4E series is available in two memory options 512KB and 1MB in BGA and QFP packages.
