Zigbee integrated MCU and WiFi integrted MCU from Marvell

Marvell has announced the Marvell 88MZ100 ZigBee microcontroller system on a chip (SoC) for home automation and LED lighting control applications historically found in four separate chips:
Certified ZigBee Pro stack and IEEE802.15.4-2003 / 2006 transceiver.
32-bit ARM Cortex -M3 microcontroller running at 32- or 64 MHz with Marvell's proven peripheral IPs and up to 31 GPIOs that enable rich microcontroller applications.
On-chip DC / DC converter, which can directly take battery input from 2 to 3.6 volts.
In package 512 KB serial flash with QSPI interface to the ARM Cortex-M3.

Marvell has also announced the new 88MC200 Wi-Fi microcontroller SoC which, together with Marvell's Avastar 88W878x 802.11n Wi-Fi SoC and comprehensive Smart Energy software stack, is designed to provide a highly cost-effective, flexible and easy-to-use hardware/software solution for a range devices and appliances such as refrigerators to thermostats.

"Original equipment manufacturers of smart energy devices and lighting need an integrated solution that combines a microcontroller and wireless connectivity for the correct balance of performance, power consumption and wireless networking that enables these devices to be controlled and accessed from anywhere at any time," said Yonghua Song, vice president of Central Engineering at Marvell Semiconductor, Inc. "Marvell's 88MZ100 is a total system solution that enables superior smart LED lighting control for the mass market. This easy-to-install solution is manufacture-ready for both consumer and commercial audiences at a low bill of materials cost."

The 88MZ100 ZigBee gateway acts as an adaptor that facilitates control of both ZigBee and Wi-Fi enabled smart devices using a standard IP network infrastructure.

The 88MZ100 is touted to offer best-in-class coexistence performance in the 2.4GHz ISM band where Wi-Fi and Bluetooth devices reside and offers high sensitivity of -104dBm .

The 88MZ100 ZigBee software stack features a set of host APIs that provide users full control of the home lighting via the Marvell Wi-Fi / ZigBee Gateway reference design. Using ZigBee's cost-effective green and global wireless networking standard, the 88MZ100 and Marvell Wi-Fi/ZigBee gateway enable consumers to control their household devices from their mobile phone, connected consumer electronics device or dedicated website through an intuitive user interface (UI).
