System developers designing high-end embedded control applications need flexible options to provide scalability as projects increase in complexity. To meet these needs, Microchip Technology has announced dual- and single-core dsPIC33C digital signal controllers (DSCs) with more options to meet changing application requirements across memory, temperature and functional safety.

Microchip’s dsPIC33CH512MP508 dual-core DSC enables support for applications with larger program memory requirements. The dsPIC33CK64MP105 single-core DSC is suitable for applications that require smaller memory and footprint. Developers can easily scale across product lines using the devices, which are pin-to-pin compatible within the dsPIC33CH and dsPIC33CK families.

The dsPIC33CH512MP508 (MP5) family expands the dsPIC33CH with Flash memory growing from 128 to 512 KB and triples the program RAM from 24 to 72 KB. This enables support for larger applications with multiple software stacks or larger program memory, such as automotive and wireless charging applications. More memory is needed to accommodate AUTOSAR software, MCAL drivers and CAN FD peripherals in automotive applications.

In the dual-core devices, one core can function as a master while the other is designed as a slave. The slave core is useful for executing dedicated, time-critical control code while the master core is busy running the user interface, system monitoring and communications functions; for example, having two cores facilitates partitioning of the software stacks for parallel execution of the Qi protocol and other functions such as NFC to optimise performance in automotive wireless charging applications.

The dsPIC33CK64MP105 (MP1) family extends the dsPIC33CK family with a version for smaller memory and footprint applications, offering up to 64 KB Flash memory and 28- to 48-pin packages. Package sizes are available as small as 4 x 4 mm. This compact device offers a good combination of features for automotive sensors, motor control, high-density DC-DC applications or standalone Qi transmitters. Both single- and dual-core dsPIC33C devices enable fast deterministic performance for time-critical control applications, providing expanded context selected registers to reduce interrupt latency and bringing fast instruction execution of math-intensive algorithms.

Functional safety features include multiple redundant clock sources, fail safe clock monitor (FSCM), IO ports read-back, flash error correction code (ECC), RAM built-in self-test (BIST), write protection, analog peripheral redundancies and more. A robust set of CAN-FD peripherals, along with support for 150°C operation, make the devices suitable for use in extreme operating conditions such as under-the-hood automotive applications.
