Light Sensor
Light Sensor, ISL29023, is an integrated ambient and infrared light to digital converter with I2C (SMBus
Compatible) Interface. Its advanced self-calibrated photodiode array emulates human eye response with
excellent IR rejection. The on-chip ADC is capable of rejecting 50 Hz and 60 Hz flicker caused by artificial light
sources. The lux range select feature allows users to program the lux range for optimized counts/lux. For
ambient light sensing, an internal 16-bit ADC has been designed by using the charge-balancing technique. The
nominal ADC conversion time is 90 ms; however, the user can adjust it between 11 μs to 90 ms, depending on
the oscillator frequency and ADC resolution.

3G Modem
The MCIMX53SMD board has a mini-PCIe interface that can be used by 3G modem. The developer can use
USB port to communicate with 3G modem. No A/D audio interface is reserved for 3G modem. The developer
needs to have a 3G modem, no 3G modem is provided with the MCIMX53SMD board kit.

WiFi/BT Module
The MCIMX53SMD board also has another mini-PCIe interface that can be used by the WiFi/BT module. The
WiFi/BT module is designed by a Taiwan-based company, USI, which has Atheros as one of its major chipset
providers.
This is a half size mini card featured with steady stream of up to 150 Mbits/s wireless networking and
Bluetooth combo function to provide both technologies for enterprise and home wireless LAN and PAN
access. The half size mini card is based on the Atheros AR6003 and AR3001 integrated circuits. AR6003
supports 802.11a, 11b, 11g, and multimode 11n WLAN implementations. AR3001 provides a highly integrated,
complete Bluetooth system, and it is compliant with latest Bluetooth V2.1+EDR specification. A firmware-
based architecture can support latest industry standards in the security and quality of service (QoS), draft
802.11i and 802.11e (WMMTM) standards, respectively.
Note that this PCIe connector pin-map is just mapped to Atheros WiFi/BT module, which uses a non standard
mini-PCIe pin map. No other mini-PCIe card should be connected to this slot.
The i.MX53 processor controls WiFi part through SDIO port. A 4-line UART and an I2S are connected with BT
part.

GPS Module
The MCIMX53SMD board also has GPS module, GM22, which uses AR1520A. The AR1520A is a monolithic,
highly-integrated, 130 nm CMOS single-chip GPS receiver that combines the functionality of a single-
conversion GPS RF front-end and GPS baseband processor. A complete GPS receiver built with the AR1520A
needs only a handful of external components, such as SAW filter, TCXO, RTC crystal, and few passive
components, keeping the overall bill of materials to a minimum. Many peripherals, controlled by CPU, support
I/O that can be configured on any of the GPIO pins. The device features multiple power islands, 1.8/3V I/O
compatibility, battery backup RTC, on-chip regulators, and powerful GPS specific functions.
The i.MX53 processor controls the GPS module through UART.
5.22.
ZigBee
The MCIMX53SMD board uses MC1323x as ZigBee function. The MC1323x family is Freescale’s low cost SoC
platform for the IEEE® 802.15.4 standard. It incorporates a complete, low power, 2.4 GHz radio frequency
transceiver with transmit/receive switch, an 8-bit HCS08 CPU, and a functional set of MCU peripherals into a
48-pin LGA package. This family of products is targeted for wireless RF remote control and other cost-sensitive
