CC2431_07 Datasheet, PDF (2/14 Pages) Texas Instruments – System-on-Chip for 2.4 GHz ZigBee/ IEEE 802.15.4 with Location Engine

CC2431
Key Features (continued)
• Less than 0.6µA current consumption
in power-down mode, where external
interrupts can wake up the system
• Very fast transition times from low-
power modes to active mode enables
ultra low average power consumption
in low duty-cycle systems
• CSMA/CA hardware support
• Wide supply voltage range (2.0V –
3.6V)
• Digital RSSI/ LQI support
• Battery monitor and temperature
sensor
• 8-14 bits ADC with up to eight inputs
• 128-bit AES security coprocessor
• Two powerful USARTs with support
for several serial protocols.
• Hardware debug support
• Watchdog timer
• One IEEE 802.15.4 MAC Timer, one
general 16-bit timer and two 8-bit
timers
• RoHS compliant 7x7mm QLP48
package
• 21 general I/O pins, two with 20mA
sink/source capability
• Powerful and flexible development
tools available
Note:
The CC2431 and the CC2430 are pin compatible, and the MCU and RF parts of the
CC2430-F128 are identical to the CC2431 except the Location Engine. This data sheet
complements the CC2430 data sheet with a description of the Location Engine. For
complete information about the CC2431, please refer to the CC2430 data sheet in
addition to this data sheet.
