Cortex-M4 mcus offer gateway to the IoT
Texas Instruments has launched the Tiva TM4C129x family of mcus. The ARM Cortex-M4-based devices come with Ethernet MAC+PHY and are said to enable the creation of highly connected products that bridge the cloud and the Internet of Things (IoT).
The mcus are available with a number of simultaneous connectivity options, such as CAN and USB, as well as on chip data protection and an lcd controller.
Designers can control outputs and manage multiple events, such as lighting, sensing, motion, display and switching, using sensor aggregation capabilities with 10 I2C ports, two 12bit a/d converters, two quadrature encoder inputs, three on chip comparators, an external peripheral interface, and advanced pwm outputs.
The devices also come with 256KB of integrated sram and 6KB eeprom to support greater functionality, along with a scalable 512KB to 1MB flash.
Target applications include home/building automation gateways, connected human-machine interfaces (HMI), networked sensor gateways, security access systems and programmable logic controllers.
