名称: UMFT4222EV 开发模块
概述: 其它开发板
编号: UMFT4222EV
厂商: FTDI飞特帝亚

FTDI UMFT4222EV开发模块是一个高速USB2.0到QuadSPI/ I2C桥紧凑的32引脚QFN封装的开发模块。FT4222H需要一个外部晶振(12MHz的)的内部PLL进行操作。它支持多IO电压,3.3V,2.5V或1.8V。它也提供了128字节的一次性可编程(OTP)存储器,用于存储特定于供应商的信息的空间。该FT4222H包含SPI/ I2C配置接口。SPI接口可配置为主模式,单,双或四位数据宽度传送或从模式单位数据宽度传输。I2C接口可配置为主机或从机模式。

Features

  • Single Hi-Speed USB 2.0 chip (FT4222H) to flexible and configurable SPI/I²C interfaces.
  • SPI interface support for Single / Dual / Quad SPI Master Mode with configurable target operating speed.
  • Up to 28Mbps data transfer rate in SPI mode with quad data mode.
  • Support up to 4 slave selection control pins in SPI master mode.
  • Support Single SPI Slave Mode with SCK operating frequency up to 20MHz.
  • I²C interface support 7-bits address and fully compatible to v2.1 and v3 specification for I2C Master/Slave Mode with configurable target operating speed for 100kbit/S standard mode, 400kbit/S fast mode 1Mbit/S Fast mode plus and 3.4Mbit/S high speed mode.
  • Configurable GPIOs controlled by application software via USB bus
  • Fully support USB2.0 suspend/resume and remote wakeup
