The DP83TD555-Q1 integrates IEEE802.3 Media Access Controller (MAC) and IEEE802.1 AS timestamp enables a variety of microcontrollers with SPI interface to connect to Ethernet networks using 10BASE-T1S bus. The device also integrates IEEE 1588v2/802.1AS to enable accurate time synchronization (< 100 ns ) and hardware time-stamping for various applications.
The DP83TD555-Q1 allows for efficient system-level battery current consumption by supporting TC10 Wake/Sleep requirements. This allows a low-current sleep state in which power is gated to system components by DP83TD555-Q1. When a wake-up even is detected, the DP83TD555-Q1 initiates system start-up by driving INH high. The wide VBAT operation range allows DP83TD555-Q1 to connect to 12 V, 24 V, or 48 V battery systems.
The DP83TD555-Q1 is equipped with diagnostic features such as cable fault detection and undervoltage detection to accelerate root cause analysis.
