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.
Key Advantages:
•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

“Zeus is finally the answer for a complete smart meter SoC,” said Kris Ardis, business director for smart grid products at Maxim Integrated. “By combining metrology, security and communication, we provide a platform for any embedded smart grid equipment that needs to measure, to communicate, and to do it securely. The capabilities in ZEUS will give utilities and meter manufacturers a flexible platform that can support tomorrow’s requirements today.”
The Zeus platform includes the MAX71616, MAX71617, MAX71636, and MAX71637. Maxim will be previewing the Zeus platform at Metering, Billing/CRM Europe (Amsterdam, October 9- 11, Booth C46) and electronica (Munich, November 13-16, Hall A6, booth 163).
