The ZeroG Wi-Fi I/O contains dedicated on-chip power management hardware and software to achieve long battery life. The technology allows designers to reduce power consumption both on the ZG2100 and on the host microcontroller in order to meet the needs of a wide array of applications.

• Power-saving modes are optimized for long battery life. Battery life lasts as long as 10 years for “once-a-day-wake-up”
• Wireless architecture optimized for applications with low duty cycles and low bandwidth.
• The chip automatically goes on standby in between receive and transmit
  sessions, along with a “fast wake-up” call at the receipt of packet.
  • The Wi-Fi I/O automatically reduces power without intervention from host MCU
    No-host polling allows the host MCU to shut down while the chip remains active
  • The chip wakes up the host MCU at the receipt of data packets
• In many applications, the Wi-Fi I/O does not require the addition of external memory or an operating system, reducing overall system power consumption.
