motorola dsp56f826 product brief 3 ? two external interrupt pins ? external reset pin for hardware reset ? jtag/on-chip emulation (once?) for unobtrusive, processor speed-independent debugging ? software-programmable, phase lock loop-based frequency synthesizer for the dsp core clock ? fabricated in high-density emos with 5v tolerant, ttl-compatible digital inputs ? one time of day module energy information ? dual power supply, 3.3v and 2.5v ? wait and multiple stop modes available dsp56f826 description the dsp56f826 is a member of the dsp56800 core-based family of digital signal processors (dsps). it combines, on a single chip, the processing power of a dsp and the functionality of a microcontroller with a flexible set of peripherals to create an extremely cost-effective solution for general purpose applications. because of its low cost, configuration flexibility, and compact program code, the dsp56f826 is well- suited for many applications. the dsp56f826 includes many peripherals that are especially useful for applications such as: noise suppression, id tag readers, sonic/subsonic detectors, security access devices, remote metering, sonic alarms, pos terminals, feature phones. the dsp56800 core is based on a harvard-style architecture consisting of three execution units operating 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 applications. the instruction set is also highly efficient for c/c++ compilers to enable rapid development of optimized control applications. best in class development environment the sdk (software development kit) provides fully debugged peripheral drivers, libraries and interfaces that allow programmers to create their unique c application code independent of component architecture. the codewarrior integrated development environment is a sophisticated tool for code navigation, compiling, and debugging. a complete set of evaluation modules (evms) and development system cards will support concurrent engineering. together, the sdk, codewarrior, and evms create a complete, scalable tools solution for easy, fast, and efficient development. product documentation the four documents listed in table 1 are required for a complete description and proper design with the dsp56f826. documentation is available from local motorola distributors, motorola semiconductor sales offices, motorola literature distribution centers, or online at www.motorola.com/sps/dsp.
