A Powerful System-On-Chip for 2.4-GHz IEEE 802.15.4-2006 and ZigBee Applications - CC2538

CC2538 (ACTIVE)

A Powerful System-On-Chip for 2.4-GHz IEEE 802.15.4-2006 and ZigBee Applications

Description

The CC2538xFnn is the ideal SoC for high-performance ZigBee applications. The device combines a powerful ARM Cortex-M3-based MCU system with up to 32KB on-chip RAM and up to 512KB on-chip flash with a robust IEEE 802.15.4 radio. This enables the device to handle complex network stacks with security, demanding applications, and over-the-air download. Thirty-two GPIOs and serial peripherals enable simple connections to the rest of the board. The powerful security accelerators enable quick and efficient authentication and encryption while leaving the CPU free to handle application tasks. The low-power modes with retention enable quick startup from sleep and minimum energy spent to perform periodic tasks. For a smooth development, the CC2538xFnn includes a powerful debugging system and a comprehensive driver library. To reduce the application flash footprint, CC2538xFnn ROM includes a utility function library and a serial bootloader. Combined with the free Z-Stack PRO or ZigBee IP stacks from TI, the CC2538 provides the most capable and robust ZigBee solution in the market.
