Microchip expands memory for automotive DSCs
With ample space for sophisticated software such as Autosar, MCAL drivers and CAN FD peripherals, Microchip’s new dual- and single-core dsPIC33C Digital Signal Controller (DSC) family is targeting automotive environments.

The new dsPIC33CH512MP508 dual-core DSC enables support for applications with larger program memory requirements. The dsPIC33CK64MP105 single-core DSC adds a cost-optimised version for applications that require smaller memory and footprint. Developers can easily scale across product lines using the new devices, which are pin-to-pin compatible within the dsPIC33CH and dsPIC33CK families.

The dsPIC33CH512MP508 (MP5) family expands the recently introduced dsPIC33CH with Flash memory growing from 128 KB to 512 KB and triples the program RAM from 24 KB 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. Implementing wireless charging in automotive applications requires additional software stacks for the Qi protocol and Near-Field Communication (NFC), driving the need for even more program memory. Using Live Update capability for real-time firmware updates is essential for high-availability systems but also doubles the overall memory requirement.
