Microchip announces new single- and dual-core dsPIC33C Digital Signal Controllers (DSCs) that add more options to meet changing application requirements for memory, temperature, and functional safety. These options will help system developers design high-end embedded control applications that need flexible options to provide scalability as projects increase in complexity.
The new dual-core DSC dsPIC33CH512MP508 it is suitable for applications that require more program memory. The DSC of a core dsPIC33CK64MP105, for its part, is a cost-optimized version that is aimed at applications that need less memory and a smaller size. Developers can easily find the most suitable model thanks to the new devices, whose pins are compatible with the dsPIC33CH and dsPIC33CK families.
The dsPIC33CH512MP508 (MP5) family expands the recently introduced dsPIC33CH with Flash memory that increases from 128 KB to 512 KB and program RAM that triples from 24 KB to
72KB. All of this makes them ideal for larger applications with multiple software stacks or more program memory, such as in-car and wireless charging applications. More memory is required to install AUTOSAR software, MCAL drivers and CAN FD peripherals in automotive applications. The implementation of wireless charging in automotive applications requires more software stacks for the Qi protocol and NFC (Near-Field Communication), which in turn increases the need for more program memory. Live Update capability for real-time firmware updates is essential for high availability systems but also doubles the total memory required. On dual-core devices, one core can function as a master and the other as a slave. The slave kernel is useful for executing dedicated and time-critical control code, while the master kernel handles the user interface, system monitoring, and communications functions. For example, the availability of two cores makes it easy to split software stacks for parallel execution of the Qi protocol and other features like NFC to optimize performance in in-car wireless charging applications.
The dsPIC33CK64MP105 (MP1) family expands the recently introduced dsPIC33CK family with a cost-optimized version for smaller footprint and less memory applications, offering up to 64 KB of Flash memory and 28- to 48-pin packages starting in size from 4mm x 4mm. This compact device provides the ideal combination of features for automotive sensor applications, motor control, high-density DC/DC conversion, or stand-alone Qi transmitters. Single- and dual-core dsPIC33C devices enable fast deterministic performance for time-critical control applications by providing context-selected registers to reduce interrupt latency and speed algorithm instruction execution mathematicians.
All devices in the dsPIC33C family incorporate fully functional safety hardware to facilitate ASIL-B and ASIL-C certification in safety critical applications. Functional safety features include multiple redundant clock sources, Fail Safe Clock Monitor (FSCM), I/O port verification, Flash Error Correction code Correction Code, ECC), automatic RAM checking (RAM Built-In Self-Test, BIST), write protection and redundant analog peripherals, among others. A powerful set of CAN-FD peripherals, along with their new ability to operate to 150°C, make these devices ideal for very harsh operating environments, such as under-the-hood automotive applications.
The dsPIC33C family is supported by the MPLAB development ecosystem® from Microchip, including Microchip's free MPLAB X Integrated Development Environment (IDE), MPLAB code configurator, MPLAB XC16 C compiler, and MPLAB in-circuit programming/debugging tools. MotorBench version 2.0™ Microchip's Development Suite, now supporting high-voltage motors up to 600V, is also available to customers to help tune motors using a Field Oriented Control (FOC) algorithm.
Various development boards and PIM modules (Plug-in Modules) are available for the entire family of devices. Development tools for the new devices include the dsPIC33CH Curiosity board (DM330028-2), the dsPIC33CH512MP508 PIM for general application designs (MA330046), the dsPIC33CH512MP508 PIM for motor control (MA330045), the dsPIC33CK64MP105 PIM for general application (MA330047), the dsPIC33CK64MP105 PIM for motor control with external op amp (MA330050-1) and the dsPIC33CK64MP105 for motor control with internal op amp (MA330050-2).
The dsPIC33CH512MP5 devices are now available in 48/64/80-pin TQFP, 64-pin QFN, and 48-pin uQFN packages. The dsPIC33CK64MP1 devices are now available in 28-pin SSOP, 28/36/48-pin uQFN, and 48-pin TQFP packages.
The dsPIC33CH Curiosity Development Board is now available for $39,99 per unit. The aforementioned dsPIC33C PIM development boards are now available for $25,00 per unit.
