Overview:

The Texas Instruments EV2400 EVM interface boardEV2400 EVM interface board enables an IBM-compatible or other type PC (with the required driver for its particular platform) to communicate with the Texas Instruments SMBus, I²C, HDQ, or DQ interface gas gauges via a Universal Serial Bus (USB) port. In addition to this board, PC software is required to interpret the gas gauge data to complete the evaluation system.

EV2400EV2400 Controller
- The EV2400 controller is an MSP430F5529MSP430F5529 running at 4 MHz. The controller firmware is stored in flash memory and is executed by the core at power-up.
- The controller communicates with target device(s) through either: a 2-wire SMBus communication port, a 1-wire HDQ port, or a 2-wire EEPROM I²C port.
- The 2-wire SMBus communication port supports both SMBus and I²C protocols. CRC-8 checksum verification for the data packets prevents data corruption over the USB.
USB Interface (USB)
- The interface board connects to a USB port (version 1.1 or later) on a host computer and is powered from the port.
- All communication over the USB is human Interface device (HID) class.
- Drivers are built into Windows ® and most of the operating systems.
HDQ Interface (HDQ)
- This interface allows a host computer to interact with a slave or target device through the 1-wire HDQ interface.
- The ports are labeled with the corresponding signal names above each port connector. Connect the signal and a ground reference (VSS) to a target device.
I²C Interface (I²C)
- This interface allows a host computer to interact with I²C interfaces, such as a battery monitor device and EEPROM through a 2-wire I²C interface. Connect the data, clock, and a ground reference (VSS) to a target device.
SMBus Interface (SMBus)
- This interface allows a host computer to interact with an SMBus interface device such as a battery monitor device through a 2-wire SMBus interface. Connect the data, clock, and a ground reference (VSS) to a target device.

Key Applications: analog and digital sensor systems, data loggers, and others that require connectivity to various USB hosts.
