Status Explanations for product status codes

Active: In Production.


The MAX7322 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the capabilities of the MAX7322 I²C port expander with four push-pull outputs and four inputs. The MAX7322 EV kit also includes Windows® 98SE/2000/XP-compatible software, which provides a simple graphical user interface (GUI) for exercising the MAX7322's features.

The MAX7322 evaluation system (EV system) includes a MAX7322 EV kit and a Maxim CMAXQUSB serial-interface board.

The CMAXQUSB board connects to a PC's USB port and allows the transfer of I²C commands to the MAX7322 EV kit.

The EV kit comes with the MAX7322ATE+ installed. The MAX7322 EV kit can also be used to evaluate the MAX7319/MAX7320/MAX7321/MAX7323. Contact the factory for free samples of the pin-compatible MAX7319ATE+, MAX7320ATE+, MAX7321ATE+, or MAX7323ATE+ to evaluate these parts.
