Atmel's SAM4SP32A is a new compact, highly integrated solution that combines a Cortex-M4 processor-based MCU, 2MB of dual-bank Flash, 160KB SRAM and a high-performance PLC transceiver in a single-chip SoC that lowers overall system costs.

The SAM4SP32A SoC is fully compliant with the latest PRIME (Power Line Intelligent Metering Evolution) PLC specification.

In order to support the complex protocol required by smart meters to make firmware upgrades of the application and the protocol stack independently in the field, the new SoC integrates Atmel's PLC technology with a high-performance Cortex-M4 MCU with 2MB of program memory on a dual-bank configuration. The new solution also leverages the powerful peripherals of the Cortex-M4 MCU, including serial peripheral interface (SPI), TWI and USARTS, to support the various communication interfaces required by smart metering applications.

Atmel's SAM4SP32A SoC offers a high level of integration and power efficiency, along with extraordinary sensitivity of up to 34.8dBuV and a dynamic range of up to 73.18 dB. The new SoC includes an integrated low-power amplifier that consumes 40 percent less power than other solutions on the market today.

Opitimizing the Design Process

To optimize the process of designing PLC-based smart metering solutions, the SAM4SP32A will be supported by Atmel Studio 6, the latest version of the company's popular integrated development environment (IDE) that now supports both Atmel 32-bit ARM ^® Cortex™-M series processor-based and Atmel 8/32-bit AVR ^® based microcontrollers (MCUs). For the first time, the extensive AVR customer base of more than 100,000 engineers and the designers of ARM Cortex-M series processor-based applications have all of the tools required to develop and debug Atmel MCU applications in a single, seamless environment. Atmel Studio 6 is available free of charge. 

To further accelerate the design process, Atmel's SAM4SP32A SoC will also be available with a SAM4SP32AAEK-99 evaluation kit that includes two boards, a complete set of software libraries, application examples, a PHY tester, PRIME Network Manager and PC USI test. The evaluation kits will be available in Q1FY13.
