DSC integrates control, sensing, security

Microchip’s dsPIC33AK256MP306 digital signal controller (DSC) combines a 200-MHz, 32-bit core and double-precision FPU with high-resolution PWMs and high-speed ADCs. It also includes a hardware crypto accelerator with support for post-quantum cryptography (PQC). Offered in a 36-pin VQFN package, the DSC saves space and simplifies PCB layout in power conversion, motor control, and intelligent sensing applications.

The dsPIC33AK256MP306’s four PWM generator pairs (eight outputs) deliver fine edge placement (FEP) resolution down to 78 ps. Three 12-bit SAR ADCs operate at up to 40 Msamples/s, alongside 5-ns comparators and 12-bit DACs with slope compensation. These features enable fast, deterministic control loops for high-efficiency DC/DC converters, auxiliary rails, and high-frequency SiC/GaN systems. An integrated touch controller extends support to sensing and HMI functions.
To address growing cybersecurity requirements, the dsPIC33AK256MP306 family supports secure boot, firmware updates, and debug, with hardware-accelerated PQC aligned to emerging standards for connected control systems. Live update capability maintains uninterrupted firmware upgrades in high-availability systems.
Prices for the dsPIC33AK256MP306 start at $1.97 in lots of 5000 units.
