Description

The CC2543 is an optimized system-on-chip (SoC) solution with data rates up to 2Mbps built with low bill-of-material cost. The CC2543 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 1-KB RAM, and many other powerful features. The CC2543 has efficient power modes with RAM and register retention below 1 µA, making it highly suited for low-duty-cycle systems where ultra-low power consumption is required. Short transition times between operating modes further ensure low energy consumption.

The CC2543 is compatible with the CC2541/CC2544/CC2545. It comes in a 5-mm × 5-mm QFN32 package, with SPI/UART/I2C interface. The CC2543 comes complete with reference designs from Texas Instruments.

The device targets wireless consumer and HID applications. The CC2543 is tailored for peripheral devices such as wireless mice.
