• SPI Application Communication Interface
– 40 bit datagram length (1 ReadWrite bit + 7 address bits + 32 data bits)
– Immediate SPI read response (register read access by single datagram)
– SPI clock frequency fSCK up to 2 MHz (8 MHz write, 8 MHz read w/ 500 ns pause after address)
• TRINAMIC Real Time Monitoring Interface
– High frequency sampling of real-time data via TRINAMIC’s real-time monitoring system
– Only single 10 pin high density connector on PCB needed
– Enables frequency response identification and auto tuning options with TRINAMIC’s IDE
• UART Debug Interface
– Three pin (GND, RxD, TxD) 3.3 V UART interface (1N8; 9600 (default), 115200, 921600, 3M bps)
– Available as port for external position sensors (e.g. absolute encoder together with processor)
– Transparent register access parallel to embedded user application interface (SPI)
• Supply Voltages
– 5V and 3.3V; VCC_CORE is internally generated
• IO Voltage
– 3.3V for all digital IOs (choosable by VCCIO Supply)
– 5V common mode analog input voltage range (1.25V ... 2.5V differential operating range)
• Clock Frequency
– 25 MHz (from external oscillator)
• Packages
– QFN76
