ADSP-2184LBSTZ-160

ADSP-2184LBSTZ-160 is an ADSP-218xL series DSP microcomputer. It consists of four single chip microcomputers optimized for digital signal processing applications. It integrates up to 160K bytes of onchip memory configured as up to 32K words (24-bit) of program RAM, and up to 32K words (16-bit) of data RAM. Power down circuitry is also provided to meet the low power needs of battery-operated portable equipment. The ADSP-218xL’s flexible architecture and comprehensive instruction set allow the processor to perform multiple operations in parallel. The ADSP-218xL series instruction set provides flexible data moves and multifunction (one or two data moves with a computation) instructions.

• Up to 19ns instruction cycle time, 52MIPS sustained performance
• Single-cycle instruction execution, single-cycle context switch
• 3-bus architecture allows dual operand fetches in every instruction cycle
• Multifunction instructions, low power dissipation in idle mode
• Dual-purpose program memory for both instruction and data storage
• Independent ALU, multiplier/accumulator, and barrel shifter computational units
• Powerful program sequencer provides zero overhead looping conditional instruction execution
• 2 double-buffered serial ports with companding hardware and automatic data buffering
• 13 programmable flag pins provide flexible system signalling
• 100-lead LQFP package, -40°C to +85°C temperature range
