1.3 Description

Start your design with the industry’s first programmable FCC, IC, CE, and Wi-Fi Certified Wireless

microcontroller (MCU) module with built-in Wi-Fi connectivity. Created for the Internet of Things (IoT), the

SimpleLink CC3200MOD is a wireless MCU module that integrates an ARM Cortex-M4 MCU, allowing

customers to develop an entire application with a single device. With on-chip Wi-Fi, Internet, and robust

security protocols, no prior Wi-Fi experience is required for faster development. The CC3200MOD

integrates all required system-level hardware components including clocks, SPI flash, RF switch, and

passives into an LGA package for easy assembly and low-cost PCB design. The CC3200MOD is provided

as a complete platform solution including software, sample applications, tools, user and programming

guides, reference designs, and the TI E2E™ support community

The applications MCU subsystem contains an industry-standard ARM Cortex-M4 core running at 80 MHz.

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 CC3200 family includes flexible embedded RAM for code

and data; ROM with external serial flash bootloader and peripheral drivers; and SPI flash for Wi-Fi network

processor service packs, Wi-Fi certificates, and credentials.

The Wi-Fi network processor subsystem features a Wi-Fi Internet-on-a-chip™ and contains an additional

dedicated ARM MCU that completely off-loads the applications MCU. This subsystem includes an 802.11

b/g/n radio, baseband, and MAC with a powerful crypto engine for fast, secure Internet connections with

256-bit encryption. The CC3200MOD supports station, access point, and Wi-Fi Direct™ modes. The

device also supports WPA2 personal and enterprise security and WPS 2.0. 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 than 7 μA of current.

3.3 Pin Attributes and Pin Multiplexing

The module 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 module reset) and register control.

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. Table 3-2 describes 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 of 2, 4, and 6 mA. Drive strength is configurable individually for each

pin.

• All I/Os support 10-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 VBAT 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 CC3200MOD 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 CC3200MOD can occur. To

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

• All devices interfaced to the CC3200MOD must be powered from the same power rail as

the chip.

• Use level-shifters between the module and any external devices fed from other

independent rails.

• The nRESET pin of the CC3200MOD must be held low until the VBAT supply to the

module is driven and stable
