Frequently Asked Questions

How fast is the CPU core in SM320F28335GBS and what does that mean for real-time control loops?

The SM320F28335GBS runs a 32-bit C28x core at up to 150 MHz, allowing control loop execution times well under 10 µs. This speed enables high-bandwidth feedback loops needed in servo drives, power converters, and motor controllers that must respond to fast transient events.

Which communication interfaces are available on SM320F28335GBS for industrial connectivity?

The device provides SPI, I2C, SCI (UART-compatible), McBSP, and a CAN 2.0 interface. With up to 3 SCI ports and 1 CAN port, it supports multi-node industrial networks operating at standard baud rates up to 1 Mbit/s.

For a digital power supply design, how many PWM outputs does SM320F28335GBS provide and at what resolution?

SM320F28335GBS offers 18 PWM output channels, including 6 high-resolution HRPWM channels with sub-nanosecond edge placement capability at 150 MHz system clock. This resolution enables precise duty-cycle control in DC-DC converters and multi-phase inverter designs.

What voltage supply does SM320F28335GBS require and are there multiple rails needed?

SM320F28335GBS requires a 1.8 V core supply and a separate 3.3 V I/O supply rail. The dual-supply architecture is mandatory as noted in the device specifications, and both rails must be stable before the device exits reset to ensure reliable operation.

When would SM320F28335GBS be selected over a standard automotive-grade C2000 device?

The SM320F28335GBS is a space-qualified screening variant suited for aerospace and satellite applications that require operation across -55°C to 125°C and radiation-tolerant environments. Standard automotive C2000 parts are screened to AEC-Q100 Grade 1, but they lack the space-level qualification and radiation assurance offered by this variant.
