The applications MCU subsystem contains an industry-standard ARM Cortex-M4core running at80MHz.

The device includes a wide variety of peripherals,including a fast parallel camera interface,I2S,SD/MMC, UART,SPI,I2C,and four-channel ADC.The CC3200family includes flexible embedded RAM for code and data and ROM with external serial flash bootloader and peripheral drivers.

The Wi-Fi network processor subsystem features a Wi-Fi Internet-on-a-Chip and contains an additional dedicated ARM MCU that completely offloads the applications MCU.This subsystem includes an802.11 b/g/n radio,baseband,and MAC with a powerful crypto engine for fast,secure Internet connections with 256-bit encryption.The CC3200device supports Station,Access Point,and Wi-Fi Direct modes.The device also supports WPA2personal and enterprise security and WPS2.0.The Wi-Fi Internet-on-a-chip includes embedded TCP/IP and TLS/SSL stacks,HTTP server,and multiple Internet protocols.

The power-management subsystem includes integrated DC-DC converters supporting a wide range of supply voltages.This subsystem enables low-power consumption modes,such as the hibernate with RTC mode requiring less than4μA of current.

Figure3-1.QFN64-Pin Assignments

3.1Pin Attributes and Pin Multiplexing

The device makes extensive use of pin multiplexing to accommodate the large number of peripheral functions in the smallest possible package.To achieve this configuration,pin multiplexing is controlled using a combination of hardware configuration(at device reset)and register control.

NOTE

TI highly recommends using the CC3200pin multiplexing utility to obtain the desired pinout.

The board and software designers are responsible for the proper pin multiplexing configuration.Hardware does not ensure that the proper pin multiplexing options are selected for the peripherals or interface mode used.

Table3-1describes the general pin attributes and presents an overview of pin multiplexing.All pin multiplexing options are configurable using the pin mux registers.

The following special considerations apply:

?All I/Os support drive strengths of2,4,and6mA.Drive strength is configurable individually for each pin.

?All I/Os support10-μA pullups and pulldowns.

?These pulls are not active and all of the I/Os remain floating while the device is in Hibernate state.

?The VIO and V BAT supply must be tied together at all times.

?All digital I/Os are nonfail-safe.

NOTE

If an external device drives a positive voltage to the signal pads and the CC3200device is

not powered,DC current is drawn from the other device.If the drive strength of the external

device is adequate,an unintentional wakeup and boot of the CC3200device can occur.To

prevent current draw,TI recommends any one of the following:

?All devices interfaced to the CC3200device must be powered from the same power rail

as the chip.

?Use level-shifters between the device and any external devices fed from other

independent rails.

?The nRESET pin of the CC3200device must be held low until the VBAT supply to the

device is driven and stable.
