개요

Description

The MCP2221A-I/SL is Microchip’s USB 2.0 Full-Speed USB-to-UART/I2C bridge in an 8-pin package. It lets a PC talk to a microcontroller or peripherals without USB firmware, by providing:
- A single UART channel (PC ↔ MCU) and an I2C master interface for I2C devices.
- A couple of configurable GPIOs for simple control or handshaking.
- A firmware/driver stack that exposes the device as a virtual COM port (or HID) with Microchip’s API, so software on the PC can configure UART speed, I2C operations, and GPIOs.
Key reasons to use it: quick, low-cost USB connectivity for MCU debugging, data logging, or I2C sensor networks; no custom USB firmware required on the MCU side.
Notes: the “I/SL” suffix indicates Industrial temperature range (-40°C to 85°C) and RoHS-compliant (lead-free) packaging. Check the datasheet for exact UART baud rates, I2C speeds, GPIO count, voltage levels, and driver requirements.

Features

Key features of MCP2221A-I/SL:
- USB 2.0 Full-Speed device (12 Mbps) and USB HID-like API
- USB-to-UART/I2C bridge: supports UART (TX/RX) and I2C Master interfaces
- I2C Master operation up to 400 kHz
- Four configurable GPIO pins (dir, state, basic I/O for user signaling)
- Easy software support: MCP2221 Utility, HID APIs, Windows/Linux/macOS drivers
- Industrial temperature range: -40°C to +85°C (I variant)
- RoHS-compliant, SL packaging (lead-free, small-outline package)
- Low-power operation with USB suspend/wake capability
- Simple, no-host-driver-needed basic operation; drivers available for full functionality

Package

MCP2221A-I/SL comes in an 8-pin Small Outline Package (SOIC-8). It is RoHS-compliant/lead-free with industrial temperature range (-40°C to 85°C).

Pinout

- Pin count: 16 pins (MCP2221A-I/SL in a SOIC-16 package).
- Function: USB 2.0 Full-Speed to UART/I2C bridge with four general-purpose I/O pins (GP0–GP3). It provides a USB interface to a host and can operate as a UART bridge (Tx/Rx) with optional I2C master mode on two of the GPIOs.

Manufacturer

- Manufacturer: Microchip Technology Inc.
- What kind of company: An American multinational semiconductor company that designs and manufactures embedded-control products, including microcontrollers, analog/mixed-signal ICs, memory, and interfaces (e.g., USB-to-UART).

Application

- USB-to-UART bridge for MCU/embedded system development, debugging, and serial consoles
- USB-to-I2C master interface for I2C sensors, EEPROMs, displays, etc.
- USB-to-SPI master interface for SPI devices
- GPIO for bit-banging control and peripheral interfacing
- PC-based programming, data acquisition, testing, and lab instrumentation
- Industrial-grade version suitable for automation and instrumentation in harsh (industrial) environments
