APC330采用集成度非常高的射频芯片Si4438，其在性能与成本之间取得了极佳的平衡，性价比优势极为突出，在1Kbps速率下的接收灵敏度高达-120dBm，丝毫不逊于同类成本高昂的产品；APC330采用高效的循环交织纠检错编码（CRC），使其保有了非常高的抗干扰能力，非常适用于对性能要求高且对成本要求极为苛刻的智能电能表无线抄表。
APC330尺寸与引脚均兼容APC250、APC320，使得Si4438, Si4432, Si4463模块产品得以灵活使用和自由替换。
应用：
- 无线抄表, 智能电表无线手抄、组网集抄系统
- 无线电子点餐机、点菜机
- 各种温度、流控、压力、位置、角度仪表通信监测
- 住宅及各种建筑物智能控制, 工业自动化数据采集
- 安防、报警系统, 各种基础设施监控管理
- 油井、矿山实时监测, 通信系统配电监测、无功补偿系统
