MCP2210 1.0 FUNCTIONAL DESCRIPTION The MCP2210 also has 256 bytes of integrated user EEPROM. The MCP2210 device is a USB-to-SPI Master converter which enables USB connectivity in applications that have an SPI interface. The device reduces external components by integrating the USB termination resistors.
MCP2210 1.1 Supported Operating Systems The following operating systems are supported: • Windows XP/Vista/7 • Linux • Mac OS 1.1.1 1.3.2 SPI MODULE POWER-UP CONFIGURATION Default parameters: • 1 Mbit • 4 bytes to transfer per SPI transaction • GP1 as Chip Select line ENUMERATION The MCP2210 will enumerate as a USB device after Power-on Reset (POR). The device enumerates as a Human Interface Device (HID) only. 1.4 1.1.1.
MCP2210 1.5 USB Transceiver FIGURE 1-1: The MCP2210 has a built-in, USB 2.0, full-speed transceiver internally connected to the USB module. VDD The USB transceiver obtains power from the VUSB pin, which is internally connected to a 3.3V internal regulator. The best electrical signal quality is obtained when VUSB is locally bypassed with a high-quality ceramic capacitor. The internal 3.3V regulator draws power from the VDD pin. In certain scenarios, where VDD is lower than 3.
MCP2210 In order to meet the inrush current requirements of the USB 2.0 specifications, the total effective capacitance appearing across VBUS and ground must be no more than 10 µF. If it is more than 10 µF, some kind of inrush limiting is required. For more details on Inrush Current Limiting, see the current Universal Serial Bus Specification. According to the USB 2.0 specification, all USB devices must also support a Low-Power Suspend mode.
MCP2210 1.6 GP Module The GP module features nine I/O lines. 1.6.
MCP2210 1.7 EEPROM Module The EEPROM module is a 256-byte array of nonvolatile memory. The memory locations are accessed for read/write operations solely via USB host commands. The memory cells for data EEPROM are rated to endure thousands of erase/write cycles, up to 100K for EEPROM. 1.9 Oscillator The input clock must be 12 MHz to provide the proper frequency for the USB module. USB full-speed is nominally 12 Mb/s. The clock input accuracy is ±0.25% (2,500 ppm maximum).
MCP2210 2.0 MCP2210 FUNCTIONAL DESCRIPTION The MCP2210 uses NVRAM to store relevant chip settings. These settings are loaded by the chip during the power-up process and they are used for GP designation and SPI transfers. The NVRAM settings at power-up (or Reset) are loaded into the RAM portion of the chip and they can be altered through certain USB commands. This is very useful since it allows dynamic reconfiguring of the GPs or SPI transfer parameters.
