CC2530 chip introduction

Introduction

The CC2530 combines the performance of a leading RF transceiver with the industry-standard enhanced 8051 CPU, in-system programmable flash memory, 8-KB RAM and many other powerful features. CC2530 has four different flash memory versions: CC2530F32/64/128/256, which have 32/64/128/256KB of flash memory respectively. The CC2530 has different operating modes, making it particularly suitable for systems with ultra-low power requirements. Short transition times between operating modes further ensure low energy consumption.

The CC2530F256 combines Texas Instruments' industry-leading golden unit ZigBee protocol stack (Z-Stack™) to provide a powerful and complete ZigBee solution.

CC2530F64 combines Texas Instruments' golden unit RemoTI to better provide a powerful and complete ZigBee RF4CE remote control solution.
