       TICC2510Fx / CC2511Fx Low-Power SoC (System-on-Chip) with MCU, Memory,2.4 GHz RF Transceiver, and USB Controller

       产品概述：

       The CC2510Fx/CC2511Fx is a true low-cost 2.4GHz system-on-chip (SoC) designed for lowpower wireless applications. The CC2510Fx/CC2511Fx combines the excellent
performance of the state-of-the-art RF transceiver CC2500 with an industry-standard
enhanced 8051 MCU, up to 32 kB of in-system programmable flash memory and 4 kB of
RAM, and many other powerful features. The small 6x6 mm package makes it very suited
for applications with size limitations.
       The CC2510Fx/CC2511Fx is highly suited for systems where very low power consumption is required. This is ensured by several advanced low-power operating modes. The CC2511Fx adds a full-speed USB controller to the feature set of the CC2510Fx. Interfacing to a PC using the USB interface is quick and easy, and the
high data rate (12 Mbps) of the USB interface avoids the bottlenecks of RS-232 or low-speed USB interfaces.
