7 / 158

– PWM auto scaling for transparent change of PWM frequency during motion

• SPI 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 up to 1MHz (8MHz in future version)

• TRINAMIC RealTime 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

–

Advanced controller tuning support by frequency response identiﬁcation and advanced 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, or 3M bps)

– 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 input range for diﬀerential analog inputs,

1.25V input range for single ended inputs

• Clock Frequency

– 25 MHz (external oscillator needed)

• Packages

– QFN76
