A True System-on-Chip Solution for 2.4-GHz IEEE 802.15.4 and ZigBee Applications

The CC2530 is a true system-on-chip (SoC) solution for IEEE 802.15.4, Zigbee and RF4CE applications. It enables robust network nodes to be built with very low total bill-of-material costs. The CC2530 combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8-KB RAM, and many other powerful features. The CC2530 comes in four different flash versions: CC2530F32/64/128/256, with 32/64/128/256 KB of flash memory, respectively. The CC2530 has various operating modes, making it highly suited for systems where ultralow power consumption is required. Short transition times between operating modes further ensure low energy consumption.

Combined with the industry-leading and golden-unit-status ZigBee protocol stack (Z-Stack) from Texas Instruments, the CC2530F256 provides a robust and complete ZigBee solution.

Combined with the golden-unit-status RemoTI stack from Texas Instruments, the CC2530F64 and higher provide a robust and complete ZigBee RF4CE remote-control solution.

CC2530EMK评估模块套件

The CC2530 Evaluation Module Kit contains two CC2530 Evaluation Modules, which can be used either as standalone modules (requires external power) or connected to e.g. the SmartRF05EB Evaluation Boards (not included in kit) for full control from the PC. The evaluation modules can be used as a reference module for prototyping and for verifying the performance of the CC2530 RF IC. The CC2530 RF SoC enables both consumer and industrial grade applications by offering state-of-the-art selectivity/co-existence, excellent link budget, operation up to 125℃ and low voltage operation.
