Introduction

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