Product Overview
The CC3220S is a Texas Instruments SimpleLink Wi-Fi wireless MCU built around an Arm Cortex-M4 application MCU subsystem operating at 80 MHz. It provides 256 KB of user-dedicated application RAM for CC3220S designs and uses external serial flash for storage, with no integrated on-chip flash in this device comparison.
Wireless networking support includes 802.11b/g/n station mode, 802.11b/g access point mode for up to 4 stations, and Wi-Fi Direct operation as Client and Group Owner. The network processor subsystem supports IPv4 and IPv6 TCP/IP, 16 simultaneous TCP/UDP sockets, and 6 simultaneous TLS/SSL sockets using SSLv3, TLS 1.0, TLS 1.1, and TLS 1.2.
For embedded control, the MCU integrates up to 27 GPIO pins, a 4-channel 12-bit ADC, SD, SPI, I2C, UART, and I2S/PCM interfaces, plus 4 general-purpose timers with 16-bit PWM mode. The RGK VQFN-64 package has a 9.00 mm x 9.00 mm body and 0.5 mm pitch, supporting space-constrained Wi-Fi connected assemblies across -40°C to +85°C operation.
