CC2430 PRELIMINARY (rev. 1.01) 2005-09-15 Page 1 of 225
A True System-on-Chip solution for 2.4 GHz IEEE 802.15.4 / ZigBee
™
Applications
• 2.4 GHz IEEE 802.15.4 systems
• ZigBee™ systems
• Home/building automation
• Industrial Control and Monitoring
• Low power wireless sensor networks
• PC peripherals
• Set-top boxes and remote controls
• Consumer Electronics
Product Description
The
CC2430
comes in three different versions:
CC2430-F32/64/128, with 32/64/128 KB of
flash memory respectively. The
CC2430
is a
true System-on-Chip (SoC) solution
specifically tailored for IEEE 802.15.4 and
ZigBee™ applications. It enables ZigBee™
nodes to be built with very low total bill-of-
material costs. The
CC2430
combines the
excellent performance of the leading
CC2420
RF transceiver with an industry-standard
enhanced 8051 MCU, 32/64/128 KB flash
memory, 8 KB RAM and many other powerful
features. Combined with the industry leading
ZigBee™ protocol stack (Z-Stack) from Figure
8 Wireless / Chipcon, the
CC2430
provides the
market’s most competitive ZigBee™ solution.
The
CC2430
is highly suited for systems where
ultra low power consumption is required. This
is ensured by various operating modes. Short
transition times between operating modes
further ensure low power consumption.
Key Features
• High performance and low power 8051
microcontroller core.
• 2.4 GHz IEEE 802.15.4 compliant RF
transceiver (industry leading
CC2420
radio
core).
• Excellent receiver sensitivity and robustness to
interferers
• 32, 64 or 128 KB in-system programmable
flash
• 8 KB SRAM, 4 KB with data retention in all
power modes
• Powerful DMA functionality
• Very few external components
• Only a single crystal needed for mesh network
systems
• Low current consumption (RX: 27mA, TX:
25mA, microcontroller running at 32 MHz)
• Only 0.9µA current consumption in power-down
mode, where external interrupts or the RTC
can wake up the system
• Less than 0.6µA current consumption in stand-
by 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
• AES security coprocessor
• Two powerful USARTs with support for several
serial protocols.
• Watchdog timer
• One IEEE 802.15.4 MAC Timer, one general
16-bit timer and two 8-bit timers
• Hardware debug support
• 21 general I/O pins, two with 20mA sink/source
capability
• Powerful and flexible development tools
available
• RoHS compliant 7x7mm QLP48 package
