DESCRIPTION
The CC2538xFnn is the ideal SoC for high-performance ZigBee applications. It combines a powerful ARM Cortex
M3-based MCU system with up to 32K on-chip RAM and up to 512 K on-chip flash with a robust IEEE 802.15.4
radio. This enables it 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 boot loader. Combined with the free to use
Z-Stack PRO or ZigBee IP stacks from Texas Instruments, the CC2538 provides the most capable and robust
ZigBee solution in the market

SWRS096A – DECEMBER 2012 – REVISED APRIL 2013
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

The CC2538 contains a power on reset (POR) module and a brown out detector (BOD) that prevent the device from operating under
unsafe supply voltage conditions. In the two lowest power modes, PM2 and PM3, the POR is active but the BOD is powered down,
which gives a limited voltage supervision.
If the supply voltage is lowered to below 1.4 V during PM2/PM3, at temperatures of 70°C or higher, and then brought back up to good
operating voltage before active mode is re-entered, registers and RAM contents that are saved in PM2, PM3 may become altered.
Hence, care should be taken in the design of the system power supply to ensure that this does not occur. The voltage can be
periodically supervised accurately by entering active mode, as a BOD reset is triggered if the supply voltage is below approximately
1.7 V.
