Hardware Description
• 4 KB of on-chip RAM
• USB 2.0 Full Speed (12 Mbps) with dedicated on-chip 3.3 V regulator; supports control, interrupt,
isochronous, and bulk transfers; supports endpoint 0 and up to six additional endpoints; endpoints
5 and 6 can be combined to provide double buffering capability
3.7 MC13202 ZigBee Transceiver
The MC13202 is a short-range, low-power, 2.4 GHz industrial, scientific, and medical (ISM) band
transceiver. The MC13202 contains a complete packet data modem which is compliant with the IEEE
802.15.4 standard PHY (physical) layer. This allows the development of proprietary point-to-point and star
networks based on the 802.15.4 packet structure and modulation format.
Combined with an appropriate microcontroller (MCU), the MC13202 provides a cost-effective solution
for short-range data links and networks. Interface with the MCU is accomplished using a four-wire serial
peripheral interface (SPI) connection and an interrupt request output which allows for the use of a variety
of processors.
MC13202 features:
• 2.0 V to 3.4 V power supply range
• Operating temperature range of –40 °C to 85 °C
• Buffered transmit and receive data packets for simplified use with MCUs
• Three power-down modes for power conservation
• Two internal 16-bit timer comparators
• Programmable frequency clock output for use by MCU
• Seven general-purpose input/output (GPIO) signals
3.8 MPXV5050 Pressure Sensor
The MPX5050/MPXV5050G series piezoresistive transducer combines advanced micromachining
techniques, thin-film metallization, and bipolar processing to provide an accurate high-level analog output
signal that is proportional to the applied pressure.
MPXV5050 features:
• 2.5% maximum error over 0 °C to 85 °C
• Ideally suited for microprocessor-based or microcontroller-based systems
• Temperature compensated over –40 °C to +125 °C
• Patented silicon shear stress strain gauge
3.9 OSRAM Pictiva OLED Display OS128064PK27MY0B00
OLED displays are a self-emissive technology that normally requires less power than LCD backlights.
These displays only consume power if a pixel is turned on. This feature makes OLED displays ideal for
battery-powered applications. The specific OLED being used in this application is a 128 x 64 pixel display
