The ADSP-217x also has a Bus Grant Hang Logic (BGH) feature.The ADSP-217x provides 2K words (24-bit) of program RAM and 2K words (16-bit) of data memory. The ADSP-2172 provides an additional 8K words (24-bit) of program ROM. Power-down circuitry is also provided to meet the low power needs of battery operated portable equipment. The ADSP-217x is available in 128-pin TQFP and 128-pin PQFP packages.Fabricated in a high-speed, double metal, low power, CMOS process, the ADSP-217X operates with a 30 ns instruction cycle time. Every instruction can execute in a single processor cycle.The ADSP-217x's flexible architecture and comprehensive instruction set allow the processor to perform multiple operations in parallel. In one processor cycle the ADSP-217x can:generate the next program addressfetch the next instructionperform one or two data movesupdate one or two data address pointersperform a computational operationThis takes place while the processor continues to:receive and transmit data through the two serial portsreceive and/or transmit data through the host interface portdecrement timer

The ADSP-2184L is a member of the ADSP-218x family. The ADSP-2184L is one of the lowest cost pin compatible devices in the ADSP-218x family. It can be designed into systems the same way as all other ADSP-2100 devices.The ADSP-2184L combines the ADSP-2100 family base architecture (three computational units, data address generators and a program sequencer) with two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O, and extensive interrupt capabilities.BenefitsAlgebraic assembly language supports C language-style constructs for easy programming100-lead LQFP package provides for space and power savings (16mm x 16mm)On-chip RAM and 4 DMA ports make reprogramming easy16-bit DMA port makes bus interfacing easier5 sleep and powerdown modes maximize battery life.
