The i.MX28 features low power consumption to enable long battery life in portable
applications. The integrated power management unit includes highly-efficient on-chip
DC-DC converters. The power management unit also includes an intelligent battery charger
and detector for Li-Ion cells and is designed to support Adaptive Voltage Control (AVC),
which can reduce the system power consumption by half. AVC also allows the chip to
operate at a higher peak CPU operating frequency than typical voltage control systems. The
DC-DC converters and the clock generators can be reprogrammed on-the-fly to trade off
power versus performance dynamically.
To provide the maximum application flexibility, the i.MX28 integrates a wide range of I/O
ports. It can efficiently interface to nearly any type of flash memory, serial bus, LCD or
HDMI/MHL transmitter. It is also ready for advanced connectivity applications such as
Bluetooth, WiFi and Cellular Data Model through its integrated 4-bit SDIO controller,
high-speed (3.25 Mb/s) UARTs and secondary USB host PHY.
