　　i.MX28/MC13224V - Home Energy Gateway Reference Platform

　　i.MX28 ARM9™ processor and ZigBee® MC13224V Platform in Package solution Current energy transmission methods create a demand for a more intelligent interface between the utility-controlled smart grid and the consumer. The Freescale home energy gateway (HEG) reference platform meets that challenge. Acting as the interface between the smart grid and energy-consuming in-house objects, the HEG allows every point of the smart home to be connected and controlled from a central location, enabling power efficiency and energy optimization.

　　家庭能量网关(HEG)优势:

　　• Provides value to the consumer by allowing power configuration, predefined control management (HVAC) and energy production checks (solar panels, wind turbines)

　　• Provides value to the utility provider by performing granular real-time demand control,delivering alerts (tariff, peak) and designing consumer profiles for accurate energy reduction automation

　　• Provides a friendly user interface to encourage user interaction and long-term use

　　• Provides a highly integrated and flexible platform to help shorten development time and reduce time to market

　　• Dedicated hardware support for AES128- based authenticated boot, signed/ authenticated firmware and dedicated hardware acceleration for AES, 3DES, SHA,MD5 encryption/decryption/hash algorithms and secure off-chip storage to address security, safety and privacy concerns

　　• Based on the low-power Freescale ARM926TM based i.MX28 system-on-chip (SoC) solution with power management unit, Ethernet, LCD controller and dual High-Speed USB with embedded PHY
