ET1150 | EtherCAT ASICNew

The EtherCAT SubDevice Controller ASIC ET1150 offers additional functions to those already included in the ET1100.

• drop-in compatible with ET1100 (3.3 V designs)
• single power supply option, integrated DC/DC
• increased DPRAM: 15 kB
• 16 FMMUs & 16 SyncManager
• dual process data interface (PDI)
• 4 x independent DC latch & sync signals
• new PDIs: SPI-Master, Quad-SPI, Octal-SPI
• up to 5x faster PDI compared to ET1100 (config-dependent)
• OTP one-time programmable memory for device information, configuration, and application usage
• up to 5x lower power consumption (config-dependent)
• JTAG for ESC status, boundary scan test, and OTP programming
• built-in RAM self-test (BIST)
• supports gigabit & fiber-optic PHYs (100 Mbit/s mode)

Like all Beckhoff ESCs, the EtherCAT protocol is processed in the hardware, thus guaranteeing high performance and real-time capability, regardless of any downstream slave microcontrollers and the software implemented on them. The supply voltage is 3.3 V or 2.5 V; the core voltage of 1.1 V is generated by the integrated LDO or, newly, by the integrated DC/DC converter, or can alternatively be fed in directly. The ET1150 supports I/O voltages of 3.3 V/2.5 V/1.8 V in two sections for PDI signals and communication ports 0 and 1.
