From motor drives to data centers, an integrated approach is helping reduce complexity while improving responsiveness, efficiency and long term system security.
Microchip Technology has expanded its dsPIC33A digital signal controller portfolio with the introduction of the dsPIC33AK256MPS306 family, targeting high-density AI data center power, complex motor control and intelligent sensing applications. Designed to meet increasing demands for deterministic real-time control, higher efficiency and enhanced cybersecurity, the new devices integrate control, analog and security capabilities into a compact form factor.
Built on a 200 MHz 32-bit core with a double-precision floating point unit, the architecture combines high-resolution 78 ps pulse width modulation, multiple 40 MSPS 12-bit analog-to-digital converters, high-speed comparators and digital-to-analog converters. This integration supports fast and predictable control loops required in applications such as DC DC power conversion, auxiliary power systems and sensing platforms, including those using silicon carbide and gallium nitride technologies operating at high switching frequencies.
The family also incorporates hardware-based security features designed to address evolving cybersecurity requirements. These include support for secure boot, secure firmware updates and secure debugging, along with library support for post-quantum cryptographic algorithms aligned with CNSA Suite 2.0. Hardware acceleration for cryptographic functions and live update capability further support uninterrupted operation in connected real-time systems such as data center power supplies.
In addition to control and security, the devices offer multiple communication interfaces including I3C, CAN FD, LIN, SPI, I2C and SENT, enabling integration into scalable telemetry and sensor networks. Features such as fast trigonometric execution and support for motor feedback interfaces including BiSS-C, EnDat and encoder systems allow implementation of responsive control algorithms, including field-oriented control.
An integrated touch controller and high-speed ADCs with oversampling support simplify sensing and human machine interface designs, while high levels of integration help reduce external components and overall system complexity. Developed in line with functional safety processes such as ISO 26262 and IEC 61508, the devices are intended for safety-critical applications and are designed for operation in demanding environments.
“We’re seeing customers look beyond individual components and focus on how quickly and confidently they can bring a system to life,” said Joe Thomsen, corporate vice president of the digital signal controller business unit at Microchip. “These DSCs combine control, analog and security capabilities in a single device, helping teams manage complexity and meet evolving performance and cybersecurity requirements from early design through deployment.”
