1 / 80 page  2016 Microchip Technology Inc. DS20005565A-page 1 MCP2221A Features: Universal Serial Bus (USB) • Supports Full-Speed USB (12 Mb/s) • Implements USB Protocol Composite Device: - Communication Device Class (CDC) for USB-to-UART conversion - Human Interface Device (HID) for I2C device control and configuration • 448-Byte Buffer to Handle Data Throughput at Any Supported UART Baud Rate: - 64-byte transmit - 384-byte receive • Human Interface Device (HID) for Both I2C Communication and Control: 64-byte buffer to handle data throughput at any I2C baud rate • Fully-Configurable VID and PID Assignments and String Descriptors • Bus Powered or Self Powered • USB 2.0-Compliant: TID# 40001594 USB Driver and Software Support • Enumerates as a Composite USB Device (CDC and HID) Using Standard Drivers for Virtual Com Port (VCP) on the Following Windows® Operating Systems: XP® (SP3), Vista®, 7, 8, 8.1 and 10 • Configuration Utility for Establishing a Custom Boot-Up Configuration •I2C/SMBus Terminal • Windows DLL CDC and Universal Asynchronous Receiver/Transmitter (UART) Options • Communications Device Class (CDC) for the USB-to-UART Option • Responds to SET LINE CODING Commands to Dynamically Change Baud Rates • Supports Baud Rates: 300-460800 •UART TX and RX Pins Only • Serial Number Used During the CDC Enumeration Can Be Enabled By Using the Microchip-provided Configuration Utility or By Calling the Proper API From the Support Libraries for this Device I2C/SMBus • The Device Runs as an I2C Master. The Data to Write/Read On the I2C Bus is Conveyed By the USB Interface. •I2C Master: - Up to 400 kHz clock rate - Supports 7- or 10-bit addressable devices; 10-bit addressable devices are supported through the PC host library - Supports block reads/writes of up to 65,535 bytes long • SMBus Master: - Supports all of the SMBus transfers - SMBus functionality is achieved through a combination of chip and support library processing - Up to 400 kHz clock rate General Purpose Input/Output (GPIO) Pins • Four General Purpose Input/Output Pins • All GP Pins Can Be Assigned to Other Functionalities Other Functionalities • UART Activity LED Outputs (UTX and URX) • SSPND Output Pin • USBCFG Output Pin (Indicates When the Enumeration Has Completed) • Three ADC Inputs • One DAC with Two Possible Output Options • Clock Reference Output: 12 MHz or Other Configurable Values • External Interrupt Edge Detection Other • Operating Voltage: 3.0 to 5.5V • Electrostatic Discharge (ESD) Protection: > 4 kV Human Body Model (HBM) • Industrial (I) Operating Temperature: -40°C to +85°C Note: The MCP2221A is identical to the MCP2221 in all aspects except for the maximum supported baud rate of the UART, which has been increased from 115200 (MCP2221) to 460800 (MCP2221A).
