ZHCSHX5A November 2017 – March 2018 DP83TC811R-Q1
PRODUCTION DATA.
Electrostatic discharge is a serious issue for electronic circuits and if not properly mitigated can create short-term issues (signal integrity, link drops, packet loss) as well as long-term reliability faults. The DP83TC811R-Q1 has robust integrated ESD circuitry and offers an ESD sensing architecture. ESD events can be detected on both the xMII and MDI pins independently for further analysis and debug.
Additionally, the DP83TC811R-Q1 provides an interrupt status flag; bit[11] in the INT_STAT1 Register 0x0012 – Interrupt Status Register #1 when an ESD event is logged in the ESDS Register 0x0448 – Electrostatic Discharge Status Register. Hardware and software resets are ignored by the ESDS register to prevent unwarranted clearing.
