An onboard balun along with a TX/RX switch allows direct connection to a single-ended 50-Ω antenna. The integrated PA provides programmable output power typically from -30 dBm to +4 dBm, and the RX LNA provides -95 dBm sensitivity. This solution also has onboard bypass capacitors and crystal load capacitors for the smallest footprint in the industry. All components are integrated into the package except the crystal and antenna.Figure 3-3. MC1322x RF InterfaceAugmenting the core device on the Sensor Node are:• Low-cost 2.4 GHz ISM Band radio• 2.0 USB connection• User interface with pushbuttons, and LEDs• Versatile power sources and management• Debug / development port• Audio subsystem• Pressure, temperature, and accelerometer sensors• GPIO connector for system expansionUsers are encouraged to reference the board schematic for the topics covered in the following sections.3.3 Power Management and MeasurementTo allow maximum versatility, the Sensor Node can be powered via a DC source (typically an AC-DC converter; nominally 5 Vdc), the USB node, or an onboard battery pack with 2 AA alkaline batteries.• The DC source or USB will automatically shutdown the battery supply.• The DC source and the USB power are regulated to 3.3 V, however, the raw battery pack voltage directly supplies the circuitry• All sources are isolated via diodes.• An on/off switch and a power-on LED are provided (see Section 4.2.2, “On/Off Switch and Power On Indicator”).ANALOGTRANSMITTERANALOGRECEIVERRFTX/RXSWITCHBALUNLNAPA
System Overview and Functional Block Descriptions1322x Sensor Node Reference Manual, Rev. 1.1 3-4 Freescale Semiconductor• Zero-ohm resistors are provided to allow isolation and measurement of various system components (see Section 4.2.3, “Power Measurement”)3.4 Low-cost 2.4 GHz ISM Band radioThe MC1322x provides an onboard balun, antenna switch, and LNA. The only external component required for the radio is an antenna. The Sensor Node provides a pcb printed metal F-antenna for a complete solution. Figure 3-4 shows the RF network external to the MC1322x.• Typical nominal output power is 0 dBm, with +4 dBm max• Typical sensitivity is -95 dBm.• Frequency range is 2405 to 2480 MHz• Typical range (outdoors, line of sight) is 300 metersFigure 3-4. Sensor Node RF Network.3.5 USB InterfaceFor many applications or demonstrations it is desirable to connect the Sensor Node to a PC or other device. A USB port is provided with a USB “B” receptacle plug. The port is connected to a FTDI FT232R USB UART device that appears as a Virtual COM port (VCP) to the PC. PC drivers are available with the module.The USB interface is configured as a “Bus Powered” device and will therefore draw all required power from the USB interface. The device is USB 2.0 full speed compatible. 3.6 User InterfaceThe Sensor Node provides multiple means for user interface for both debug and demonstration.• Four individual pushbuttons can be used as input, and a 4-direction tactile joystick switch with center push is wired in parallel with the individual pushbuttons. These pushbuttons have interrupt generation capability.• Four individual LEDs can be used as indicators for debug or status.

System Overview and Functional Block Descriptions1322x Sensor Node Reference Manual, Rev. 1.1 Freescale Semiconductor 3-53.7 Debug/Development InterfaceThere is a standard JTAG debug port (for pinouts see Section 4.6, “Debug/Development Connector (ARM JTAG Interface)”). A 20-pin connector is provided for a standard JTAG debug interface that only requires a simple interface cable to connect to the PC and uses standard ARM software development tools.3.8 SensorsThe SN provides a temperature sensor, a pressure sensor, and a three axis low-g accelerometer. All three sensors provide analog voltage outputs and require use of the MC13224/225 ADCs.NOTE• There are two VREFH voltages. ADC2_VREFH is tied to the device VCC and moves with the VCC voltage, i.e., either the regulated voltage or the battery voltage. ADC2_VREFH is useful if the application wants the ADC reference to scale with the supply voltage (as for audio), however, it is unreliable for a fixed voltage reference such as the temperature sensor. In contrast, ADC1_VREFH is tied to a fixed 1.5 V reference (see Section 4.10, “ADC Voltage References”). This fixed reference should be used for battery operation where a known voltage is required.• All sensor voltage outputs are conditioned with RC filtering to help eliminate noise.• The user is referenced to the individual data sheets for each of the sensors for detailed information.3.8.1 Temperature SensorThe temperature sensor is a National Semiconductor LM61BIM3. Its accuracy is ±3°C, and its output voltage is typically 0.600 Vdc at 0°C with a slope of +10 mV/°C. The sensor requires only one ADC input and is constantly powered.Figure 3-5.

System Overview and Functional Block Descriptions1322x Sensor Node Reference Manual, Rev. 1.1 3-6 Freescale Semiconductor3.8.2 Pressure SensorThe pressure sensor is a Freescale Semiconductor MPXV5010GC6U fully integrated device. It provides a high level analog output signal that is proportional to the applied pressure. Its accuracy is ±5%, and its output voltage is typically 0.200 Vdc at 0 offset pressure with a slope of +450 mV/kPa (1.0 kPa [kiloPascal] equals 0.145 psi.). The sensor requires only one ADC input and is constantly powered .The pressure sensor has an axial port (upright tube) for connecting tubing for a pressure source. The outside dimension of the tube is 3.0 mm nominal, and the tube is accessible through the top of the plastic enclosure.3.8.3 Three-axis AccelerometerThe three-axis accelerometer is the MMA7260QR2 device from Freescale Semiconductor. The MMA7260QR2 is specified for sensitivity in four ranges (1.5g/2g/4g/6g). The range is selectable via control lines. Consult the data sheet for sensitivity and other information. Each axis requires an ADC input (three total), and the accelerometer can be powered down.3.9 Audio SubsystemThe audio subsystem provides means for simple output sounds/tones or for TELCO voice quality audio.• A 2.5mm stereo jack is provided to interface to a typical telephone-type headset with an electret microphone and a single earphone.• Audio input - The audio input is taken from the headset electret microphone (mic).— An onboard 10 k-ohm resistor circuit biases the mic for an ~1 Vdc operating voltage.— The mic AC signal is filtered and amplified through a active low-pass filter with a voltage gain of about 30 (~30 dB). The filter topology is a multiple feedback (MFB) 3-pole, linear phase design. The target cutoff frequency is 3.6 kHz. The filter is intended as an anti-aliasing filter for sampled data.— The input amplifier output is sampled via the onboard MC1322x ADC. The sampling frequency is programmable.• Audio output source - The audio output can be sourced from both a serial 10-bit DAC and a PWM timer output.— The 10-bit serial DAC uses the SSI port to send provide the digital sample data.— The PWM timer output is typically modulated to create a Class-D amplifier. Secondarily, a simple 50% duty cycle signal can provide simple tones.— The audio output source is jumper selectable via J7• Audio output processing - The DAC or PWM out signal is filtered through an active 2-pole LPF. From the filter the signal passes through a passive attenuator, and then is amplified and driven to either an on-board speaker or the headset earphone.— The attenuator provides a volume control that is controlled via a software 32 linear tap programmable, non-volatile digital potentiometer. The interface to the potentiometer is the I2C port.

The user should take care to avoid conflict.• Power supply voltage is provided— Current draw should be limited to 50 mA.— A separate regulated voltage can be enabled• Provision is made to supply an external reference clock if desired.3.11 ClocksThe MC1322x Sensor Mode provides for two system clock sources.• MC1322x Reference Oscillator - The default frequency for the reference oscillator is 24 MHz and the mounted crystal X1 is a 24 MHz device that meets MC1322x specifications. There are two additional options for the module— X1 can be replaced by a 13-26 MHz crystal (it must meet MC1322x specifications), however, the onboard PLL must be used in this case. The pcb provides for PLL filter components, but these are not populated.— An external clock source can be supplied as the reference source (typically 24 MHz). The frequency must be accurate to +/-40ppm. The external clock source is supplied through GPIO Connector J2, and crystal X1 must be removed and capacitor C58 mounted (see Chapter 5, “Schematic, Board Layout, and Bill of Material”, Sheet 1).— 32.768 kHz Crystal Oscillator - Provision is also made for an optional secondary 32.768 kHz crystal X2. This oscillator can be used for a low power accurate timebase. The module comes without this crystal and its load capacitors C7 and C12 unmounted (see Chapter 5, “Schematic, Board Layout, and Bill of Material”, Sheet 1).
