Key Features
- USB 2.0 Full Speed interface bridging to UART and I2C/SMBus for direct PC-to-embedded connectivity without custom drivers
- 4 configurable GPIO pins with dedicated ADC and DAC functions enabling mixed-signal control over a single USB cable
- DIP-14 through-hole package ideal for rapid prototyping and lab bench tools requiring minimal soldering infrastructure
Applications
The MCP2221-I/P is commonly used as a USB-to-serial bridge in PC-connected embedded development setups, allowing direct communication with I2C sensors, EEPROMs, and UART-based modules at up to 1.5 MBps. It suits custom USB HID devices and test fixtures where a host PC controls peripheral hardware through a simple USB cable. Its integrated GPIO with 10-bit ADC and 5-bit DAC channels make it valuable for PC-controlled analog measurement and stimulus applications.

Frequently Asked Questions
What USB speed and data throughput can the MCP2221-I/P achieve?
The MCP2221-I/P operates as a USB 2.0 Full Speed device at 12 MHz, supporting data transfer rates up to 1.5 MBps. This makes it suitable for moderate-bandwidth serial bridging tasks such as streaming sensor data or firmware loading over a standard USB port.
Can the MCP2221-I/P drive I2C sensors directly, and what voltage levels does it support?
Yes, the MCP2221-I/P natively supports I2C and SMBus at standard (100 kHz) and fast (400 kHz) modes on its 3.3 V or 5 V I/O pins. It can directly interface with sensors operating at those voltage levels without level-shifting hardware in most bench or prototyping scenarios.
For a PC-based analog data logger, how many ADC channels does MCP2221-I/P provide?
The MCP2221-I/P includes 3 analog input channels with 10-bit resolution and 1 DAC output channel with 5-bit resolution. These allow a PC application to sample up to 3 analog signals and output one analog voltage, covering basic signal monitoring and control tasks at low cost through a single USB connection.
How does the DIP-14 package of MCP2221-I/P compare to its SOIC and SSOP alternatives for production boards?
The DIP-14 package has a 2.54 mm pin pitch and 300 mil body width, occupying more board space than the SOIC-14 (1.27 mm pitch) or SSOP-14 options. For volume production requiring compact SMD assembly, the MCP2221A-I/SL SOIC variant is preferred, while the DIP-14 excels in through-hole prototyping and socketed lab setups.
