Smart-Meter System-on-a-Chip Combines Metrology, Security, and Communication

Maxim Integrated Products, Inc. introduces Zeus, an advance in integration and security protection for the smart grid. Zeus is a complete smart-meter system-on-a-chip (SoC) that offers highly accurate metrology, multiple layers of security, and plenty of processing horsepower for today's advanced communication protocols.

As smart meters become more connected, the need for security is paramount to protect against energy theft and cyber attacks on the grid. Zeus provides meter manufacturers with a platform for development in multiple end markets, supporting a wide range of security and communication requirements. A built-in cryptographic module secures communication; a secure bootloader prevents unauthorized firmware modification; and tamper detection assures providers that any attempts to physically attack the meter will be detected, recorded, and reported.

Features

• Superior metering accuracy: multiple ADC channels each run at 10ksps, offering 0.1% accuracy over a 5,000:1 dynamic range
• Future proof to support tomorrow's applications: uses a 120MHz ARM® Cortex M3 application processor and a 40MHz, 32-bit MAXQ30 microcontroller with DSP support for the metering function
• Multicore architecture supports WELMEC separation of legally relevant and irrelevant functions to ease validation
