# [EC618](https://doc.soc.xin/EC618)
* [eigencomm](http://www.eigencomm.com/): [Cortex-M3](https://github.com/SoCXin/Cortex)
* [L3R3](https://github.com/SoCXin/Level): 204 MHz## [简介](https://github.com/SoCXin/EC618/wiki)
[EC618](http://www.eigencomm.com/Content/1117083.html) 是上海移芯通信科技2018年发布的更高集成、更低功耗、更优成本、更小尺寸的Cat.1bis芯片,支持3GPP R13/R14 Cat.1bis标准。也是当前最低成本Cat.1模组采用的方案,模组价格低至¥18。
内部集成电源管理芯片,支持WiFi Scan,支持无外部32K晶体,以更低成本支出客户多样化功能需求。
### 关键参数
* 26/102/204 MHz Cortex-M3
* 1MB SRAM + 4MB SiP NOR flash
* 支持供电 3.1v - 4.5v
* 3GPP R14 Cat.1bis standard: DL 10Mbps/ UL 5Mbps
* LB: 617 MHz - 960 MHz (5, 8, 12, 13, 14, 18, 19, 20, 26, 28, 71)
* MB: 1710 MHz - 2200 MHz (1, 2, 3, 4, 25, 34, 39, 66)
* HB: 2300 MHz - 2690 MHz (7, 38, 40, 41)
* SPIx2,I2Cx2,GPIOx32,UARTx3,PWMx6,ADCx4,USIMx2,FEM IOx8,OneWirex1,RTCx1,WDTx1,PWRKEY
* 封装 LFBGA,134balls (6.1*6.1*1.14mm,pitch 0.5mm)接收灵敏度等射频指标综合水平更优,TDD频段接收灵敏度相对竞品提高2-3dB,低至-101.x dBm,有效提升弱信号下传输成功率

[EC618](https://github.com/SoCXin/EC618) 同类Cat.1bis竞品包括:
* [ASR1606](https://github.com/SoCXin/ASR1606)
* [ASR1601](https://github.com/SoCXin/ASR1601)
* [V8850](https://github.com/SoCXin/V8850)
* [UIS8910DM](https://github.com/SoCXin/UIS8910DM)Cat.4速率更高,上行最高50Mbps、下行最高150Mbps的,但在功耗、集成度、价格方面很难满足部分行业的物联网应用需求,而Cat.1兼顾制式、性能、功耗、成本等优势,尤其成本比Cat.4低近30%。
