This device includes the Diagnostic Tool Kit, providing an extensive list of real-time monitoring tools, debug tools, and test modes. Within the toolkit is the first integrated electrostatic discharge (ESD) monitoring tool. The device can count ESD events on MDI as well as providing real-time monitoring through the use of a programmable interrupt. Additionally, the DP83TC812-Q1 includes a pseudo-random binary sequence (PRBS) frame generation tool, which is fully compatible with internal loopbacks, to transmit and receive data without the use of a MAC. The device is housed in a 6.00mm × 6.00mm, 36 pin VQFN wettable flank package. This device is pin-2-pin compatible with DP83TG720 (1000BASE-T1) and is also form factor compatible with DP83TC811. This means a PCB layout is useable for DP83TC811, DP83TC812, DP83TC814, and DP83TG720.
