This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
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.
