Smart metering is gaining momentum as the world’s leading economies overhaul outdated power grids and build out a smart grid that will improve how power is deployed and conserved. To help advance innovation in the energy management industry, Freescale has introduced a turnkey metering reference design built upon an advanced microcontroller (MCU) customised for the electrical metering market. The polyphase reference design, based on Freescale’s advanced MCF51EM256 ColdFire MCU, is an implementation of a single-phase or three-phase smart electrical meter. The reference design contains necessary hardware and software to make development of smart meters quick and easy.
With a rich set of integrated peripherals, including a 16-bit analog-to-digital converter with a programmable delay block, an independent realtime clock with calendaring function, dual secure Flash memory banks, an automated meter reading (AMR) interface and a liquid crystal display (LCD) driver, the MCF51EM family provides low overall system cost, low power consumption, reduces maintenance costs with remote firmware updates, makes it easier to secure and protect the meter and supports a wide range of display panels for smart meters.
The polyphase reference design includes the necessary design documentation and software to help customers quickly develop a production meter design. It has been designed and tested against several International Electrotechnical Commission (IEC) standards.
