2.4 GHz
CC2544
CC2543/44/45 is a family of 2.4GHz
RF Value Line System-on-Chip (SoC)
with MCU, 32KB Flash and 1/2KB
RAM on a single die. They feature
2-Mbps data rate, 102dB link budget
and <1µA sleep current with sleep
timer running. The family members are
distinguished by different number of
general I/O pins, and CC2544 has a
USB interface.
The CC2543-CC2544 Development
Kit provides a complete hardware
performance test platform and generic
software development environment for
2.4-GHz RF proprietary applications.
The kit includes two CC2543-based
RF evaluation modules, one CC2544-
based USB dongle, general purpose
development boards (SmartRF05EB)
for software and hardware prototyping,
cables, antennas and documentation
to get you up and running with the
CC2543, CC2544, and CC2545 quickly
and easily.
Complete RF and MCU development
is done with the CC2543-CC2544
Development Kit. Out-of-the box,
RF range and performance can be
tested using the free SmartRF Studio.
Code development can be done on
embedded 8051 core used in the
development kit, which also includes
peripherals like a dot matrix LCD
display and various other interfaces.
