A True System-on-Chip solution

CC2430 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-ofmaterial 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. This data sheet contains preliminary data, and supplementary data will be published at a later date. Chipcon reserves the right to make changes at any time without notice in order to improve design and supply the best possible product. The product is not yet fully qualified at this point. 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 RAM, 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 standby 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.
