Sub-1 GHz wireless MCU with up to 32 kB flash memory



The CC1110Fx, CC1111Fx is a true low-power sub- 1 GHz system-on-chip (SoC) designed for low power wireless applications. The CC1110Fx, CC1111Fx combines the excellent performance of the state-of-the-art RF transceiver CC1101 with an industry-standard enhanced 8051 MCU, up to 32 kB of in-system programmable flash memory and up to 4 kB of RAM, and many other powerful features. The small 6x6 mm package makes it very suited for applications with size limitations.

The CC1110Fx, CC1111Fx is highly suited for systems where very low power consumption is required. This is ensured by several advanced low-power operating modes. The CC1111Fx adds a full-speed USB 2.0 interface to the feature set of the CC1110Fx. 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.
