CHIPCON AS, represented in Australia by Clarke & Severn , has released a single-chip IEEE 802.15.4 and ZigBee system-on-chip. The CC2430 combines the features of Chipcon’s CC2420 with an 8051 MCU, 128 kBytes of FLASH memory and eight kBytes of RAM.

Applications include building automation, industrial monitoring and control systems, and wireless sensor networks. It will enable OEMs to develop complex wireless network products using the CC2430 as the only active device in the system, reducing both time to market and production costs. It can also be used as a general 2.4GHz direct sequence spread spectrum device for a number of systems not using IEEE 802.15.4 or ZigBee. ZigBee is a wireless network technology that provides low node cost and long battery life.

The MCU used in the CC2430 is an 8051 eight-bit, single-cycle microcontroller core. The device is equipped with as much as 128 kBytes of FLASH memory and eight kBytes of RAM. This is sufficient for ZigBee or ZigBee-like wireless network nodes, including coordinators, routers and end devices.

The device also includes features typically required in a complex wireless network technology like ADC, several timers, an AES-128 coprocessor, USARTs, watchdog timer and a sleep-mode timer with 32kHz. The CC2430 is based on Chipcon's SmartRF03 technology in 0.18µm CMOS. It is available in a 7mm x 7mm QLP 48 package.
