Texas Instruments 2.4 GHz IEEE 802.15.4 / ZigBee®

CC24x - RF Transceiver and System-on-Chip Solution with Location Engine

CC2420 RF Transceiver
The CC2420 is a true single-chip 2.4 GHz IEEE 802.15.4 compliant RF transceiver designed for low-power and low-voltage wireless applications. CC2420 includes a digital direct sequence spread spectrum baseband modem providing a spreading gain of 9 dB and an effective data rate of 250 kbps.
The CC2420 is a low-cost, highly integrated solution for robust wireless communication in the 2.4 GHz unlicensed ISM band. It complies with worldwide regulations covered by ETSI EN 300 328 and EN 300 440 class 2 (Europe), FCC CFR47 Part 15 (US) and ARIB STD-T66 (Japan).
The CC2420 provides extensive hardware support for packet handling, data buffering, burst transmissions, data encryption, data authentication, clear channel assessment, link quality indication and packet timing information. These features reduce the load on the host controller and allow CC2420 to interface low-cost microcontrollers.
The configuration interface and transmit/receive FIFOs of CC2420 are accessed via an SPI interface. In a typical application CC2420 will be used together with a microcontroller and a few external passive components. CC2420 is based on Chipcon’s SmartRF®-03 technology in 0.18 µm CMOS.

CC2431 - System-on-Chip for 2.4 GHz ZigBee / IEEE 802.15.4 with Location Engine
The CC2431 is a true System-On-Chip (SOC) for wireless sensor networking ZigBee®/IEEE 802.15.4 solutions. The chip includes a location detection hardware module that can be used in so-called blind nodes (i.e. nodes with unknown location) to receive signals from nodes with known location’s. Based on this the location engine calculates an estimate of a blind node’s position. The CC2431 enables ZigBee® nodes to be built with very low total bill-of-material costs. The CC2431 combines the excellent performance of the leading CC2420 RF transceiver with an industry-standard enhanced 8051 MCU, 128 KB flash memory, 8 KB RAM and many other powerful features. Combined with the industry leading ZigBee® protocol stack (Z-Stack™) from Texas Instruments, the CC2431 provides the market’s most competitive ZigBee® solution The CC2431 is highly suited for systems where ultra low power consumption is required. This is achieved by various operating modes. Short transition times between these modes further ensure low power consumption
