Home Energy Gateway Reference Design Based on i.MX283 Processor

Today's energy transmission methods require a smarter connection between the public smart grid and users. 

NXP(Freescale） Home Energy Gateway (HEG) can meet this need. As an interface between the smart grid and the consumer home, the Home Energy Gateway connects every smart home and centrally controls energy and energy efficiency.

The Freescale Home Energy Gateway (HEG) reference design uses the i.MX283 application processor, ZigBee module MC13224V, 8-bit MCU 9S08QE32, step-down DC/DC MC34726.

The platform includes an i.MX283 control board that connects to smart meters, home automation systems, broadband IP networks, user interfaces, microgrid power generation units via i.MX283 control, and connectivity extensions for connecting power line modems. GPRS/3G, U-SNAP connected peripherals and large-capacity memory cards.

CORE ADVANTAGES

Based on the low-power ARM9 i.MX283 processor with integrated power management, optimized power consumption by supporting advanced voltage and frequency scaling techniques;
Adopt low power ZigBee module MC13224V;
Full load power consumption 1.5W;

Low cost: The high integration of the i.MX283 processor reduces external components and uses a 4-layer PCB.

Home Energy Gateway Reference Design Framework

The  introduction of i.MX283 

The i.MX283 applications processor offers a low-power, high-performance solution that comes optimized for the general embedded industrial and consumer markets.

Enables applications such as media and smart energy gateways, handheld printers and scanners, and portable medical devices.

Reduces system cost and complexity and provides greater flexibility in system design
Provides extended temperature coverage for harsh environments.
Industrial qualification and product longevity supports the full life of the product in the field.Supported by a comprehensive suite of software and tools.
The i.MX28 processor includes an additional 128-Kbyte on-chip SRAM to make the device ideal for eliminating external RAM in applications with small footprint RTOS.
