Wireless Instrumentation Platform

Description

Crossfield’s CFT3001 Wireless Instrumentation Platform offers an easy to implement, low power solution for system integrators that need to add wireless sensor networking capability to their specialty instruments. The CFT3001 includes an 8-bit microcontroller, IEEE 802.15.4 transceiver, real-time clock, precision ADC, precision DAC, nonvolatile memory, and USB interface. All analog and digital I/O signals are brought to the edge of the board where they are available to the user through a pin array.

The CFT3001 is controlled by a Freescale HCS08 microcontroller with a watchdog timer. The MCU provides 4 KB of random access memory and 60 KB of flash memory. The flash memory can be locked with block protection to prevent readout or inspection. Three low power states are provided including Wait, Stop2 and Stop3. The CFT3001 provides in-circuit programmability through the HCS08 BDM interface.

Two 16-bit timers/pulse width modulators are integrated in the MCU as well as an 8-channel, 10-bit ADC. In addition, the CFT3001 provides an additional 4-/8-channel, 24-bit ADC and an 8-channel, 16-bit DAC for precision data acquisition and control. 32 KB of FRAM memory is available for non-volatile data logging. Wired connectivity is provided through a USB port with a Type B connector, an RS232C serial port and an I2C serial port.

The CFT3001 supports wireless connectivity using a fully compliant IEEE 802.15.4 transceiver that provides 250 Kbps OQPSK modulation across 16 channels in the 2.45 GHz ISM band. The transceiver is connected to the microcontroller and an on-board chip antenna (with an optional SMA connector to an external antenna). The IEEE 802.15.4 transceiver is ZigBee™ compliant.

The CFT3001 works in conjunction with Crossfield’s CFT3003 USB Wireless Adapter and software to provide a complete solution for wireless instrumentation.
