/IEEE 802.15.4
CC2538
The CC2538 is a cost-effective,
low-power, and full System-on-Chip
(SoC) solution specifically tailored to
IEEE 802.15.4 point-to-point, star, and
ZigBee PRO mesh network advanced
applications as well as ZigBee IP
Smart Energy 2.0 applications and
6LoWPAN products.
The CC2538 combines a fully integrat-
ed high-performance RF transceiver
with an industry-standard enhanced
Cortex
®
-M3 MCU, Flash, RAM and
other powerful supporting features
and peripherals.
The CC2538 comes in multiple
memory and feature options, among
them 256KB/512KB Flash memory,
16KB/32KB RAM memory and
multiple security features such as AES
engine with 128-, 192-, 256-bit key
support and Public Key Accelerator
ECC and RSA-2048.
