Highly integrated metering products feature a customer-programmable MPU core, RTC with battery backup, and a high-performance analog sensor interface combined with a dedicated 32-bit computation engine (CE) that handles all sample rate signal processing. With the provided CE binary files and reference MPU code, electricity meter vendors can design a wide range of single- and polyphase meter architectures using the same device platform.
These SoC metering products provide maximum design flexibility by incorporating a wide range of peripherals like LCD drivers, multiple UARTs, an IR interface, I2C, MICROWIRE™ master EEPROM interface, a number of configurable DIO pins, and in-system programmable flash memory. In addition, a complete set of ICE and development tools, programming libraries, and reference schematics enable rapid development and certification of TOU, AMR, and prepay meters that comply with worldwide electricity metering standards.
