dsPIC33C Digital Signal Controllers

dsPIC33C devices are optimized for high-performance embedded, digital power, motor control and robust applications implementing sophisticated algorithms such as wireless power, server power supplies, drones, and automotive sensors.

The dual-core dsPIC33CH has one core designed to function as master while the other functions as a slave. The slave core is used for executing dedicated, time-critical control code while the master core is busy running the user interface, system monitoring, and communications functions that are customized for your end application. The dsPIC33CH facilitates independent code development for each core by separate software teams and later enables seamless integration when brought together in one chip. If your design doesn’t require the dual cores, the cost-effective, single-core dsPIC33CK family offers the same high-performance core and peripherals as the dsPIC33CH family.

These DSCs are also designed to ease functional safety certification required by many automotive, industrial and appliance applications where safe operation and shutdown in failure situations are critical. The devices include integrated functional safety features such as RAM Built-In Self-Test (BIST) for checking RAM health and functionality, Deadman Timer (DMT) for monitoring the health of application software through periodic timer interrupts within a specified timing window, Dual Watchdog Timers (WDTs), Flash Error Correction Code (ECC), Brown Out Reset (BOR), Power on Reset (POR) and Fail Safe Clock Monitor (FSCM). Supporting an extended temperature range of −40°C to +150°C, they are also AEC Q100 Grade-0 compliant. These devices simplify functional safety (ISO 26262, IEC 61508 and IEC 60730) compliance for ASIL-B, ASIL-C, SIL-2 and Class B focused applications. Our device-specific ecosystem for functional safety readiness includes the Failure Modes, Effects, Diagnostic Analysis (FMEDA), Functional Safety Manual and Safety Diagnostic Library, all of which are shared under NDA.
