DSP56F803 Digital Signal Controller

NXP's 56F803 features a flexible set of peripherals on a single chip

Image of Freescale Semiconductor's DSP56F803 Digital Signal ControllerNXP Semiconductor's 56F803, a member of the 56800 core-based family of digital signal controllers, combines the processing power of a DSP and the functionality of a microcontroller with a flexible set of peripherals on a single chip. This creates an extremely cost-effective solution for servo and motor control, power inverter and converter applications.

The 56800 core is based on a Harvard-style architecture consisting of three execution units that operate in parallel, allowing as many as six operations per instruction cycle. The microprocessor-style programming model and optimized instruction set allow straightforward generation of efficient, compact code for both DSP- and MCU-style applications. The instruction set is also highly efficient for C compilers, enabling rapid development of optimized control applications.

Because of its low cost, configuration flexibility, and compact the 56F803 is well suited for many applications. Its many peripherals are especially useful for applications such as motor control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and control, automotive control, engine management, noise suppression, remote utility metering, and industrial control for power, lighting, and automation.
