CC257x
The CC257x family of ANT chips is the first ANT network processor solution from Texas Instruments. Meeting the requirements from new markets like mobile health, this family of chips integrates a fully functional ANT-FS Client, file system and AES-128 encryption, reducing design cycle and system cost.
- Integrated ANT-FS Client
- File System management
- AES-128 encryption
- +4dBm transmit power
- High resolution RSSI reading
The New Generation ANT Core Stack Enhancements
- High density node support – up to 300 nodes at 1 Hz Tx rate in same RF space
- Frequency agility
- Proximity search
- Scanning mode – extremely low latency for asynchronous applications such as remote control
- Low priority search – does not impact existing channels
- Channel ID management – improve device pairing efficiency
- Individual output power control per channel
