MCP2210
USB-to-SPI Protocol Converter with GPIO (Master Mode)
Features:
Universal Serial Bus (USB)
• Supports Full-Speed USB (12 Mb/s)
• Human Interface Device (HID) device
• 128-Byte Buffer to Handle Data Throughput:
- 64-byte transmit
- 64-byte receive
• Fully Configurable VID, PID Assignments and
String Descriptor (factory programming also avail-
able)
• Bus Powered (factory default) or Self-Powered
(can be selected through special USB
commands)
• USB 2.0 Compliant
USB Driver and Software Support
• Uses Standard HID Drivers (built-in support on
Windows® XP, Vista, 7, Linux and Mac OS®)
• Configuration Utility for Device’s Power-up
Configuration
• Utility for USB-SPI Communication, GPIO
Manipulation and Miscellaneous Features Usage
SPI Master Peripheral
• Supports all Four SPI modes (Mode 0, 1, 2, 3)
• Bit Rates from 1500 bps up to 12 Mbps
• Configurable Delays for SPI Transactions:
- Chip Select (assert) to 1st byte of data delay
- Data to data delay
- Data to Chip Select (de-assert) delay
• SPI Transactions Lengths of up to 65535 Bytes
Long
• Up to 9 Chip Select lines – to be used in any
combination for a given SPI transaction (the Chip
Select lines are shared between GPIOs and
alternate function pins; certain GPs – up to 9 of
them – can be assigned with the Chip Select
functionality)
General Purpose Input/Output (GPIO) Pins
• Nine General Purpose I/O Pins
EEPROM
• 256 Bytes of User EEPROM (accessible through
certain USB commands)
Package Types:
The device will be offered in the following packages:
• 20-lead QFN (5 x 5 mm)
• 20-lead SOIC
• 20-lead SSOP
