ADSP-2185L Product details

GENERAL DESCRIPTION
The ADSP-218xL series consists of four single chip microcomputers optimized for digital signal processing applications. The functional block diagram for the ADSP-218xL series members appears in Figure 1 on Page 1. All series members are pin-compatible and are differentiated solely by the amount of on-chip SRAM. This feature, combined with ADSP-21xx code compatibility, provides a great deal of flexibility in the design decision. Specific family members are shown in Table 1.
   
PERFORMANCE FEATURES
    Up to 19 ns instruction cycle time, 52 MIPS sustained performance
    Single-cycle instruction execution
    Single-cycle context switch
    3-bus architecture allows dual operand fetches in every instruction cycle
    Multifunction instructions
    Power-down mode featuring low CMOS standby power dissipation with 400 CLKIN cycle recovery from power-down condition
    Low power dissipation in idle mode
   
INTEGRATION FEATURES
    ADSP-2100 family code compatible (easy to use algebraic syntax), with instruction set extensions
    Up to 160K bytes of on-chip RAM, configured Up to 32K words program memory RAM Up to 32K words data memory RAM
    Dual-purpose program memory for both instruction and data storage
    Independent ALU, multiplier/accumulator, and barrel shifter computational units
    2 independent data address generators
    Powerful program sequencer provides zero overhead looping conditional instruction execution
    Programmable 16-bit interval timer with prescaler 100-lead LQFP and 144-ball BGA
   
SYSTEM INTERFACE FEATURES
    16-bit internal DMA port for high-speed access to on-chip memory (mode selectable)
    4M-byte memory interface for storage of data tables and program overlays (mode selectable)
    8-bit DMA to byte memory for transparent program and data memory transfers (mode selectable)
    Programmable memory strobe and separate I/O memory space permits “glueless” system design
    Programmable wait state generation
    2 double-buffered serial ports with companding hardware and automatic data buffering
    Automatic booting of on-chip program memory from bytewide external memory, for example, EPROM, or through internal DMA Port
    6 external interrupts
    13 programmable flag pins provide flexible system signaling
    UART emulation through software SPORT reconfiguration
    ICE-Port emulator interface supports debugging in final systems
