The UZ2400 is a single-chip solution for IEEE802.15.4 specification. It integrates wireless RF transceiver operating at 2.4 GHz, PHY layer baseband and MAC layer architecture. UZ2400 can be used together with a simple microprocessor such as 8051 to apply in low rate wireless applications that include home automation, consumer electronics, PC peripherals, toys, industrial automation, and more. With system supports of driver and 802.15.4 protocol stack provided, users can easily develop applications of their own.
