Frequently Asked Questions
What USB speed does MCP2221-I/ML support and what maximum data transfer rate can it achieve?
MCP2221-I/ML supports USB Full Speed at 12 Mbit/s, delivering a maximum effective data transfer rate of 1.5 MBps. This bandwidth is sufficient for high-throughput serial communication tasks such as data logging, firmware programming, and real-time sensor streaming in embedded development setups.
Which serial protocols can MCP2221-I/ML bridge to USB simultaneously?
MCP2221-I/ML bridges USB to I2C, SMBus, and UART interfaces within a single IC. The I2C port supports standard-mode 100 kHz and fast-mode 400 kHz speeds, while the UART supports configurable baud rates. This multi-protocol capability eliminates the need for separate bridge chips in mixed-interface designs.
How does the VQFN-16 package of MCP2221-I/ML compare to a DIP alternative for PCB layout?
The VQFN-16 package has a 4x4 mm footprint with 16 leads on a 0.5 mm pitch, occupying far less PCB area than an equivalent 16-pin DIP package at 19.5 mm x 6.35 mm. This makes MCP2221-I/ML suitable for compact USB adapters, dongles, and multilayer boards where minimizing component footprint is critical.
