It is intended to be used with the DSP56KCentral Processing Unit Manual (DSP56KFAMUM/AD), which describes the central processing unit, programming models, and includes details of the instruction set. TheDSP56002 Technical Data Sheet (DSP56002/D) provides timing, pinout, and packagingdescriptions (see Figure 1-1).Freescale Semiconductor, Inc...This section presents the DSP56002 features.24-bitDSP56002DSP56000Family ManualProductsCentral Processor andInstruction Manual• central processor• instruction set# DSP56KFAMUM/ADDSP56002User’s Manual# DSP56002UM/ADDevice Manual• peripherals• memoriesDSP56002Technical DataSpecification• electrical• mechanical# DSP56002/DFigure 1-1 DSP56002 Technical LiteratureMOTOROLAINTRODUCTION TO THE DSP56002For More Information On This Product,Go to: www.freescale.com1-3Freescale Semiconductor, Inc.FEATURESFreescale Semiconductor, Inc...1.2FEATURESDSP56K Central Processing Unit (CPU) Features• 20 Million Instructions per Second (MIPS) at 40 MHz• Single-Cycle 24 x 24 Bit Parallel Multiply-Accumulator• Highly Parallel Instruction Set with Unique DSP Addressing Modes• Zero Overhead Nested DO Loops• Fast Auto-Return Interrupts• Fully Static Logic, Operation Frequency Down to DC• Very Low-power CMOS Design• STOP and WAIT Low-power Standby ModesDSP56002 Features• 512 x 24 Program RAM• Two 256 x 24 Data RAM• Two 256 x 24 Data ROM (Sine and Cosine Tables)• Full Speed Memory Expansion Port with 16-bit Address and 24-bit Data Buses• Byte-wide Host Interface with DMA Support• Synchronous Serial Interface Port• Serial Communication Interface (Asynchronous) Port• 24 General Purpose I/O Pins• 24-bit Timer/Event Counter*• On-chip Emulator (OnCE) for Unobtrusive, Full Speed Debugging• Optional Program Security Feature Disables Unauthorized Program ROM andOnCE Access• PLL Based Clocking with Wide Input Frequency Range, Wide Range FrequencyMultiplication (1 to 4096) and Power Saving Clock Divider (2i, i=0,...,15) toReduce Clock Noise1.3DSP56K CENTRAL PROCESSING UNIT OVERVIEWThe DSP56K series of 24-bit modular processors is built on a common central processingunit (CPU).
In the expansion area around the CPU, the chip can support various configurations of memory and peripheral modules which may change between series members.* The first version of the DSP56002 (mask number D41G) did not have the timer/event counter. Later versions of the DSP56002 which havedifferent mask numbers do have the timer/event counter.
This mask number can be found below the part number on each chip.1-4INTRODUCTION TO THE DSP56002For More Information On This Product,Go to: www.freescale.comMOTOROLAFreescale Semiconductor, Inc.MANUAL ORGANIZATIONFreescale Semiconductor, Inc...The central components are:• Data Buses• Address Buses• Data Arithmetic Logic Unit (data ALU)• Address Generation Unit (AGU)• Program Control Unit (PCU)• Memory Expansion (Port A)Figure 1-2 shows a block diagram of the DSP56002, including the CPU and the expansionarea for memory and peripherals.
