Description

The CC2544 is an optimized system-on-chip (SoC) solution for USB applications with datarates upto 2Mbps built with low bill-of-material cost. The CC2544 combines the excellent performance of a leading RF transceiver with a single-cycle 8051 compliant CPU, 32-KB in-system programmable flash memory, up to 2-KB RAM, and many other powerful features. The CC2544 is compatible with the CC2541/CC2543/CC2545. It comes in a 5-mm × 5-mm QFN32 package, with SPI/UART/USB interface. The CC2544 comes complete with reference designs from Texas Instruments. The devices target wireless consumer and HID applications. The CC2544 is ideal for USB dongle applications.
