CFU0321 RF Module Description

The CFU0321 is a general purpose IEEE 802.15.4 RF module
designed with Smart Energy applications in mind. It features the
TI CC2520 RF transceiver, TI CC2591 2.4GHz Power Amplifier, I
MSP 430F5437 microcontroller with 256K of flash RAM and 16K of
RAM, 1MB external flash RAM, and pattern antenna. Depending on
the SKU, the following options are available:

• Board to Board connector

• Side through hole for surface mounted

The CFU0321 is designed to be surface mounted; however, board
to board connector is standard feature and allows Board to Board
connector to be attached for easy socketing.

The unit requires 2.7V – 3.6V unregulated DC supply; internal
voltage regulation supplies the radio. The nominal transmission
and reception distance is 100 meters with the on-board pattern
antenna.

TI Z-Stack 2.4 port is available for the CFU0321, along with an
implementation of the Smart Energy profile device(s). Also, the
TIMAC only firmware is available. Standard development
environment requires the MSP430 version of the IAR IDE toolset.
Programming the CFU0321 requires the HVE0704, the
development board specifically designed for the CFU0321.
Additionally a JTAG programmer is required.

Applications

The CFU0321 allows devices to join the ZigBee SE 1.x network
currently being deployed by the utility companies. The following

Cluster Library, along with the required device firmware (e.g.
In-home Display, etc.). The CFU0321 has been tested with the
Smart Energy Device Simulator, the validated test harness
solution for the ZigBee Alliance for Smart Energy 1.0 Application
Profile, and therefore assured of interoperability with all major
devices supporting Smart Energy application profiles.
