Our CP220x devices are the industry’s smallest single-chip Ethernet controllers containing an integrated Media Access Controller (MAC) and Physical Layer (PHY). The CP220x single-chip Ethernet controller contains an integrated IEEE 802.3-compliant MAC, a 10Base-T PHY and 8 kB of non-volatile Flash memory available in either a 28-pin QFN (5 x 5 mm) or 48-pin TQFP (9 x 9 mm) package. CP220x can add Ethernet connectivity to any microcontroller (MCU) or host processor with 11 or more port I/O pins. 8–位外部存储器接口总线可为符合行业标准的英特尔和摩托罗拉总线格式，提供多路复用和非多路复用模式的支持。CP2201 28 引脚 QFN 封装仅支持多重寻址。模式选择引脚用于选择总线接口模式。
