11AAxxx/11LCxxx UNI/O™ 串行 EEPROMMicrochip 11AAxxx/11LCxxx 系列设备为串行 EEPROM，具有 Microchip 的专有 UNI/O™ 串行总线。 UNI/O™ 串行 EEPROM 设备只需要与主机微控制器建立一个连接，因为时钟和数据通信组合在单个串行位流中。 结果是 UNI/O™ 设备只需要一个微控制器输入/输出，而非 I2C、Microwire 和 SPI 总线 EEPROM 设备需要的 2 至 6 个（取决于配置）。 对于设计人员，这使他们可以部署较小的主机 MCU 及更少的输入/输出，从而降低 MCU 成本和实现更紧凑的设计。### 特点### EEPROM 串行存取 - Microchip

**11AAxxx/11LCxxx UNI/O™ Serial EEPROM**

The 11AAxxx/11LCxxx family of devices are Serial EEPROMs featuring Microchip’s proprietary UNI/O™ Serial Bus. UNI/O™ Serial EEPROM devices require only one connection to a host Microcontroller as clock and data communications are combined into a single serial bit stream. The result is that UNI/O™ devices require one Microcontroller I/O instead of the 2 to 6 depending on configuration that I2C, Microwire and SPI bus EEPROM devices require. To the designer this opens up the possibility of employing a smaller host MCU with fewer I/Os, reducing the MCU cost and allowing for a more compact design.
